| How To: Replace Water Pump in 1hr:) Took me a lil over an hour, get the lisle tool, saves unnecessary work, and with a real long extension and swivel you can get to the water tube on the back of the pump and you don't have to remove the t-stat housing, you can slide it in. OP where do you live? Also the dealer quoting about a grand is right, it calls for like 8 hours in the book.

| I expect the water pump fails sometimes due to the build up of pressure instead of coming out of the rad. reservoir. It finds the weakest point and thats why it leaks out of the water pump is my guess to all this. I just hope I don't find that the headgaskets are blown. Is there a test I could do? |

| ^^^ that is kind of the general reasoning it seemed in the threads I read. When my head gaskets were out the top radiator hose was hard after sitting all night and you couldn't remove the reservoir cap without it blowing coolant everywhere. Sent from my iPhone using AutoGuide.com App
