Water Pump

[SWFLHOMES]

Has anyone done this? Any details would be greatly appreciated. My Water pump pulley has movement in it so I thought I would replace it before it failes.

I sent you a PM.

Can you also please send me the procedure? I am going to change out my water pump when I install aluminum coolant pipes.

Can I get the instructions also? Mine has a slow leak and will need replacement soon.

I'd be thrilled to take pictures and write it up as a DIY.

Thanks,

Trey

This is probably a 3 on the DIY scale. I was able to do this in 1 to 1 1/2 hours. Unfortunately I wanted to get this job done while it was below 90 degrees (Florida) so I did not take any photos. There are a couple of things I did differently (right or wrong) that made the job easier.

1. Remove the two front engine covers above the fans with a coin.

2. Remove the the y pipe (there is a connector on the bottom of the y pipe) and extensions that connect to the MAF sensors (left and right.

3. Disconnect the wires that go to the throttle adjuster and then unbolt the throttle adjuster (4 bolts).

4. There is another 1/4 inch tube and electrical connector that is an emmissions piece that needs to be disconnected because it's in the way. It's near the bottom right of the throttle adjuster.

5. Loosen the 3 water pump pully screws (WITH THE PULLY STILL ON).

TIP: If you don't remove the electric fan cover it will be difficult to get a wrench between the fan and the pully. I used my torx head bit and used an adjustable wrench sideways or perpendicular on the torx bit. They loosen real easy counter clockwise as usual.

6. Loosen the belt tensioner pully and remove the belt. I did not remove the belt completely but you will get coolant on the belt if you don't cover it when you pull the water pump.

TIP: Ease the pully off, it will take some patience and some wiggling (I used a 1/2 by 1/2 piece of wood to not damage the pully).

7. Loosen the 8 bolts that hold on the water pump.

TIP: There are similar bolts around the water pump bolts. Use the new water pump to help guide you on the bolts you can't see.

8. Lightly tap the pump ant it should come right off.

I did not drain the coolant. I recently did the coolant pipe replacement and didn't feel the need to drain it. I lost about 1 pint to 1 quart of coolant when I removed the pump. If you do this don't remove the reservoir cap. That will allow more coolant to come out. DO remove it after you complete the job and get the temperature up so the thermostat open and the system can bleed itself.

I am not a mechanic, but if I break it I own it!
