Note: Part numbers sometimes change without notice. Always double check with your supplier that you have the latest part numbers. A third (center) radiator is standard on the Porsche GT3, Boxster S and all Carrera's or Boxster's with Tiptronic transmission. As well, the third radiator is now standard on all X51 Carrera Power Kit (engine power upgrade). Although the Tiptronic radiators are plumbed differently it is obvious that Porsche did this to increase the cooling capacity of these cars. Having great concern for my engine, specifically it's cooling in the hot California weather and... knowing that what Porsche does for it's competition cars is usually a good (yet sometimes expensive) idea for our street (sometimes tracked) cars. I decided to add the GT3 radiator to my 1999 Carrera Coupe (w/factory aerokit). The goal being that extra amount of protection that the additional cooling capacity adds. Initial tests show that the highest temperatures (after hard driving) have gone down 10-20°F (7-12°C) after this installation. Here is my installation procedure: It took me 4-5 hours taking pictures and cleaning. I would expect this can be done in 3-4 hours (or less).

The parts kit from Carnewal.com. Two views (second one courtesy of Scott Mandell). Pre-assemble the Radiator. Using the numbers in the illustration you can pre-assemble some of the radiator parts using the rubber grommets (4) and the M6 Speed Nuts (6) and M6 Bolts (5). Note the radiator outlet positions and the retaining frame top and bottom (see parts list for p/n). The radiator hose connections face the car and are on the top. The top retaining bracket (2) has tabs with small hooks. The tab hooks point towards the car and the tabs themselves angle away from the car. The bottom bracket (3) has tabs that face the car. When mounted the radiator will NOT be vertical it will be at a slight angle up. Raise the car and remove the wheels. Start by jacking the car up and placing jack stands under the front wheel jack mounts. This really puts the car at a more comfortable height to work on. Next remove the front wheels. Remove the side markers. Move the wheel well liners back. Remove from the wheel well the 3 plastic rivets and the 10 mm nut. Pull the wheel well liner back as shown (I used twine). Remove the front bumper cover. There are two screws on each side at the side marker area. One is at the forward part where the side marker assembly attaches, the other is behind the side marker. Remove the screws and rivets under the nose (2 rivets and 7-9 screws). Remove the plastic cover over the front trunk latch. This is held in place by four plastic fasteners. You just rotate these 90 degrees to remove them. Carefully pull the cover off over the latch handle. Finally remove the 2 screws (now visible). Detach the air temperature sensor cable. Lift the bumper cover off and place on a padded surface to avoid scratches. Remove the air scoops. There are 5 torx screws on the scoops to remove them. On the right side you will need to feed the rubber grommet (for the temperature sensor) through the scoop to remove it. Clean the radiators. Detach the air conditioning condensers (2 torx screws) and use a soft brush and vacuum to clean the radiators and air conditioner condensers well. Loosen the radiator assembly on each side. Remove the two bolts (13 mm) under the support bracket. Then remove the (13 mm) nut that holds the bracket (inside the wheel well). This will now allow the whole assembly to move about 6 inches down and to the side allowing enough room to change the hoses. Replace the lower hose on right (passenger side) side. Using pliers slide the hose spring clamps back on the hose but don't remove the hose yet. Place a clean container (about 2 quarts should be enough) to catch the coolant when you carefully remove the hose at the radiator end first. Coolant. This about the quantity of coolant you should expect when you remove the lower hose. I would guess slightly more than one radiator capacity. Right side (passenger side) Hoses. Old hose on left new hose on right. Place the clamps on the hoses and re-attach. Before tightening down the hose clamps rotate the hose so that the small hose is correctly positioned at to the top center of the car (for the new radiator). Replace the upper hose on left (drivers side) side. Place the clamps on the hoses and re-attach. Before tightening down the hose clamps rotate the hose so that the small hose is correctly positioned at to the top center of the car (for the new radiator). This one is a little trickier but you should see the hose path as it sits up and under the fender. Left side (drivers side) Hoses. Old hose on left new hose on right. Attach the center radiator to the car. Using the M8 speed nuts place them on the brackets on the car and attach the radiator (assembly) loosely using just the top 2 bolts. Attach the small hose to the center radiator. To easily attach the left hose remove the bolt from the left side mounting (now only supported on the right) and attach the hose and tighten the clamp. Do the reverse on the other side (place bolt back in left side and remove right bolt). Finally tighten down all 4 M8 bolts to hold the radiator firmly in place. Re-attach the radiators. Carefully re-position the radiators and replace the 2 bolts and nut that holds the assembly in place. Take care to line it up as it was previously. Reattach air conditioner condensers and tighten the 2 torx screws that hold them in place. Test for leaks. Start the engine and run for at least 5 minutes while checking for leaks. If everything is tight and leak free proceed with the rest of the re-assembly. Attach center air duct. Carefully position the air duct such that the 6 protrusions snap into the places on the radiator frame. Reattach the side air scoops (5 each torx screws). Remove the center plug in the bumper cover. This may sound easier than it is. Seems Porsche uses a black silicone type sealant on this. I found the best way was to use (carefully) a utility knife to cut away as much of the sealant as possible and then carefully pull until I got a corner up and worked my way around the edges. Note: For standard (non-aerokit) front bumpers; cut the inside gasket along the line. Remove the center plug as shown in these images (courtesy of Scott Mandell) Or, you could replace the rubber bumper insert with: 996 505 553 05 01C Air Inlet for Tiptronic (or for MY02 and newer 996 505 561 02 01C). This replaces the original insert and installs across width of stock 996 bumper. Re-attach the bumper cover. Basically, the reverse of removal. Re-attach wheel well covers. Ditto, basically the reverse of removal. Re-attach the side marker lights, wheels, lower car. Again, the reverse of removal. Add coolant, check for leaks (again), and bleed system... Add a mixture of antifreeze and water using the HMZ coolant. Antifreeze in coolant: 50% gives protection down to -31°F (-35°C) 60% gives protection down to -58°F (-50°C). Be careful not to overfill (it will get pushed out on the floor). Lift the bleed valve. Start the engine and allow it to get to full operating temperature (I also ran the air conditioning to force circulation). The coolant warning light will likely start to flash. Shut the engine off and WAIT until the engine and coolant has cooled enough to remove the coolant tank cap. Then add coolant to the tank and repeat the process. You made need to do this 2-3 times. When the coolant level fails to fall then the system is bled and you can close the bleeder valve. Enjoy your "cool" car. Just to be safe it might make sense to check the coolant level a couple of times in the next one or two days. I found under heavy (track) driving in hot weather my coolant temps run 10 to 20°F (7 to 12°C) cooler now.

If brake pad wear is indicated by the warning light, the warning contact sensor (sender including wire and plug connection) must also be replaced. Replacing the warning contact sensor can be avoided by replacing the brake pads no later than when the pad thickness is 2.5 mm. Warning contact sensors with a worn wire core must be replaced. However, if only the plastic part of the warning contact is worn, replacement is not necessary. Also, do not disassemble the caliper when changing the vibration dampers (or painting the calipers) as Porsche does not sell inner seal kits. Jack up the vehicle at the lift points provided and remove the a wheel (you will need to do this for each wheel). Visually inspect the brake pads for wear. The wear limit is reached when the pad has a residual thickness of 2 mm (or less). Front Pad Replacement Remove the retainer (arrow) and extract the retainer pin inwards. Pull out the warning contact wire on the brake caliper and remove the warning contacts from the brake pad plates. Remove brake pads with a brake pad puller or use the water pump Pliers to spread the pads. (Photos are courtesy of Greg Heumann) Important Notes: Pull out brake pads together with the vibration dampers. If this is not possible (depending on wear of the brake pads), use a spatula to detach the vibration dampers from the brake pad plate before removing the pads. In both cases, first set back the brake pads as far as possible with the piston resetting fixture. If necessary, first remove some brake fluid by suction from the brake fluid reservoir. If necessary, carefully push back the piston to its original position. Fit new vibration dampers in the pistons. Do this by removing protective film from the vibration dampers before installation. Insert the brake pads. Caution: The pad backing plates (rear side of the brake pads) must not be greased. Note: If you are using Pagid (or some other 3rd party pads) you will likely have to drill the pad for the wear sensors. Just look at the old pads and drill the sensor holes in the same location. Fit new expanding spring, new retaining pin and new retainer (retaining bracket). These parts are available as a repair set and must be 'renewed' each time the pads are changed. Insert the warning contact wire and warning contacts. Firmly press the brake pedal several times with the vehicle stationary so that the brake pads assume their fit in accordance with the operating state. Next, check and, if necessary, correct the brake fluid level. Bedding in the brake pads New brake pads require a bedding-in period of approximately 125 miles. Not until then do they achieve their best friction and wear coefficient. During this period, the brakes should be subjected to full stress only in emergencies when traveling at high speed. ------------------------------------------------------------------------------------------------------------------------------ Rear Pad Replacement Remove the retainer (arrow) and extract the retainer pin inwards.

(Edit - July 25, 2006 - Updated the clutch bleeding procedure to the latest procedure as outlined in supplement 98 of the Carrera Service Manual - Loren) Parts you will need: 1 liter (minimum) 000 043 203 66 Porsche DOT 4 Brake Fluid or equal (ATE Gold or ATE Super Blue) Tools you will need: Jack 19 mm socket for wheel bolts Motive Power Bleeder (or equal) image Needle Nose Pliers 11 mm wrench for brakes; 9 mm for clutch slave (sizes vary from car to car but they are usually 9 mm or 11 mm) Plastic tubing and waste container (at least 1 liter) Jack up the vehicle at the lift points provided and remove the rear wheel (you will need to do this for each wheel). Remove the cap on the master cylinder reservoir. Remove the plastic screen using a pair of needle nose pliers. This can be a little bit challenging but it will pop off (be careful with the brake fluid.. it eats paint!) Use a syringe (or turkey baster... just don't reuse it) and suck out as much of the old fluid as possible. Fill the master cylinder reservoir with new fluid. Put the rest in the power bleeder. Screw the cap that came with the power bleeder onto the master cylinder reservoir. Put the pressure cap with the pump handle on the power bleeder and pump it up to just under 20 psi - do not go over 20 psi! Bleed order - Right rear, Left rear, Right front, Left front. Place your drain tube over the outside bleed nipple and in the bottle (remember it will need to hold a liter when you are done). Bleed the outer bleeder valve first. Open each bleeder valve until clear, bubble free brake fluid emerges. Take care to bleed at each brake caliper and at both bleeder valves. Carefully tighten the bleed screw. Wipe off the area and replace the rubber protective cap over the bleed screw. Repeat steps 8-10 for the interior bleed screw. Then reinstall the wheel and move on to the next wheel. Note: It makes sense to check the pressure and amount of fluid in the tank between wheels. Running out of fluid means starting over and getting air out. Optional Clutch Bleeding This is best done when you are bleeding the left (driver's side) rear wheel as the clutch bleed valve is mounted high above the axle on the transmission. Push the clutch pedal in by hand (very slowly) and use a long piece of wood to hold the pedal down. I wedged the other end (of the wood) between the seat and door frame -- with plenty of soft padding to avoid scratches. A second option is to have a 2nd person sit in the car and keep the clutch pedal FULLY depressed. Open the clutch bleeder valve until clear, bubble free brake fluid emerges (at least 30 seconds according to Porsche). Remove the wood. Then, pump the pedal again very slowly by hand for a further 60 seconds. After pressing the pedal down fully about 10 to 15 times, leave the pedal in its normal position. After allowing a fill time of 90 seconds, check that no more air bubbles appear at the bleeder valve (use a collecting bottle with a transparent hose). Then close the bleeder valve. Wipe off the area and replace the rubber protective cap over the bleed screw. You may notice that the clutch pedal does not return... so carefully pull it up (slowly) to it's normal position. Then depress it (slowly) a few (at least 5) times. In a few cycles the feel should return. [*]Torque the wheels bolts to 96 ftlb. (130 Nm). [*]Do a final check on the brake fluid level and top up if needed.

Note: Part numbers sometimes change without notice. Always double check with your supplier that you have the latest part numbers. Parts you will need: 1 996 110 253 01 Fuel Filter - for 2WD cars or 1 996 110 253 52 Fuel Filter - for 4WD cars Tools you will need: Tire ramps or jack (and jack stands) Various screwdrivers to remove underbody cover For the C2 the fuel filter is located in the tunnel area facing the center unit above the coolant pipes (up to and including MY01). For the C4 the fuel filter is located in the engine compartment, strapped to the coolant tank (up to and including MY01). MY02 and newer cars have the fuel filter incorporated in the fuel pump - and usually does not need to be changed. This DIY is for MY01 and older cars. Remove cover for rear and center underbody. (photo courtesy Tool Pants) Pull off ground cable on filter. Then release the rapid-action couplings by pressing on the grey surfaces and remove the fuel lines. Collect emerging fuel. Loosen the large hose clamp on the filter and remove the filter element. Re-install a new filter element and tighten the hose clamp. Join the rapid-action couplings of the fuel lines. The plug connections must engage audibly. Then push the ground cable onto the filter element. Replace the cover for the rear and center underbody.

Note: Part numbers sometimes change without notice. Always double check with your supplier that you have the latest part numbers. Parts you will need: 1 each 996 102 151 64 (or 996 102 151 66) Polyrib Belt (with air conditioning) or 1 each 996 102 151 65 Polyrib Belt (without air conditioning) Tools you will need: 13 mm socket or wrench (for air cleaner) Regular screwdriver (for air cleaner) 24 mm socket or wrench (for belt pulley) Remove air cleaner housing. Mark belt travel direction with a coloured pen (if you intend to reuse it). Note: Never remove Polyrib belt when warm. The belt will deform and could be damaged. Turn the tensioning roller 7 on the socket wrench (wrench size 24 mm) clockwise and simultaneously remove the belt from the drive pulleys. Visually inspect the condition of the belt and replace it if necessary. Check belt pulley for damage. Install Polyrib belt in the order shown. Twist the tensioning roller 7 clockwise and simultaneously place the belt on the idler pulley 8. Subsequently relieve the tensioning roller slowly. Visually check whether the belt is correctly positioned on all pulleys. Reinstall the air cleaner housing
