When i went to Orielys I asked for a water pump for a 97 Silverado with a 5.7l. Thats where I found out it was a reverse rotation pump. I am using a Equos temp guage that is mounts in the intake beside the water neck. The serpentine belt is routed correctly, it causes the water pump pulley to turn to the left wnen you are looking at the engine. I am going to get a different thermostat today, and see if that is it.
After a couple of hours of web surfing, I believe that I can have four or five problems.
1. Wrong water pump
2. Head gaskets installed wrong
3. Faulty thermostat
4. Blown head gasket
5. Air locked engine
Too address these I plan on doing the following.....
Im going to get a new thermostat installed today.
Im going to bleed the system at the Temp sending unit.
Dont think the head gaskets are faulty. No steam or vapor out the exhaust, Im not losing coolant anywhere.
The water pump will be the last resort. I will double check the # I was given if I can locate the reciept, If not when Im at Orileys I'll have them look it up. It a warranty Item. I didnt skimp on it. WAY WAY WAY too much tied up in this engine.
I found the reciept for the pump. MWP 58-147. Going to look it up on the web in a min.... Heck I even paid a core. LMAO
