The other night, driving in the rain, blocks away from my house my power steering started getting stiffer, battery light came on, e-brake light came on and I started overheating. Pulled over looked around the engine bay and notice my serpentine belt was completely off the pulleys Checked belt for wear and tear no rips damage or worn out teeth. Did the same thing with the pulleys nothing.

Today I put the serpentine belt back on checked all of the pulleys and noticed that my water pump pulley had some play in it.(I was able to move it side to side) Also noticed the belt as it was spinning on the water pump moving side to side.

Question: Do you guys think that the shaft play on the water pump pulley can be enough for a perfectly good serpentine belt to just fly off??? Or could it be something else? What else should I check? The tensioner looked and felt like it was pirty good to me idk.

 

I don't know the answer to 'is it enough'. I do know you water pump is shot.

 

^would it be enough. Would the movement side to side on the water pump pulley be enough to have the serpentine belt fall off?

 

Today the evo started overheating again. Half of the Anti freeze drained out of the overflow bottle. Wtf is going on???? Somebody help!

 

Could it be my thermostat also? So frustrating right now.

 

Obviously you have a water pump issue. Id look into that

 

Have you checked the tensioner ?

 

The tensioner is good. It's a self leveling auto tensioner. Didn't see much slack at all on the serpentine belt. Water pump is working but the car is overheating

 

Look for replace water pump. You said it has play.
When was last time u replace a pump?

 

Would I need a brand new water pump? Or can I rebuild it (heard some places rebuild them).

 

But the car has 47k on it only should the pump be going out that early??? My Honda civic has 160k pump is still good on it.

 

Buy new. If you got evo 8, you can get a aftermarket ones. Check sticky thread, one of member posted part number (60k service thread)

 

Never replaced a water pump on it pump

 

Thinks can fail. Its just luck especially when it comes to car stuff.

 

Just because the pump spins doesn't mean its working. The blades on the inside could be gone. i have seen it before. Replace the pump with a new one.
