Engine coolent bubbling ..new water pump?

Porsche Boxter 2.7 (UK)

2002

Facelift edition

Water pump was burst, has now been replaced. Began refilling with Porsche engine coolant, but struggling for the coolant and water to go down the tube, keeps bubbling and pressure keeps building up with the dial on dash ticking upto 120 (Red) after about 2/3 mins of engine 3k revs. Have been told about air pockets? Told this can be a long process, but the more coolent thats put in, i would imagine the car wouldnt be overheating but still continues to go above 90 on the dash then eventually heading towards 120. Any tips on removing air pockets or any tips on how to sort the overheating please?

Did you open the vent when you filled it? Under the black plastic cover around the fill port and oil port. Take those two caps off, and pull the dipstick out, and then the cover will come out. Lift the wire up and it will vent the air out. Open the vent, fill it up, and start the car. It may also help to drive the rear of the car up on ramps to make the coolant jug the highest point in the car.

I have not tried that, i will try this tomorrow and let you know how i get on. Should the full 22 litres (11 water) and 11 coolant be added? As there was previous water about 4 litres in it after the water pump was replaced?

Also my heating isnt working now? There is cold air comming from the inside of the car? does the air bubbles contribute to this or is it a seperate issue?

The Airlift tool by UView works great! Edited February 10, 2011 by kbrandsma

Using the Airlift tool by UView makes the job foolproof and complete in no time.

If you decide to do it without the tool, here's another step by step DIY that will do the job: http://pedrosgarage.com/Site_3/Install_3rd_Radiator_%26_Coolant_System_Bleeding_Instructions.html

The DIY also includes installing a 3rd radiator, so go down about two-thirds of the way down the page to get the bleeding instructions.

I think all your problems a the result of your system not being bled all the way. There is an official way to do it but I simply fill it up all the way, drive it about 34 of a mile where the temp gauge is getting close to the red (and which happens to put me right back at my house to). Then let cool down some, top it off and do another lap putting it close to the red again (and in front of my house again), and top it of again etc. It takes about 5 laps.
