I just recently replaced my serpentine belt and tensioner pulley. Well my drove okay afterwards but I had to put water everyday. Now my reservoir will not hold ANYTHING and wants to overheat fast. It's leaking from the bottom passenger's side. And it somewhat started sputtering when it did started leaking everything out of the reservoir. No water is in my oil, still starts, no smoke from my exhausted, and my reservoir cap is always tightly on. PLEASE HELP ME OUT WHETHER ITS MY RADIATOR, WATER PUMP, WATER HOSE, Thermostat, or something cheap!

How do you do that and what would it run me? Estimated.

Hello,

It sounds like you have a cooling fan issue. When the engine is overheating are the cooling fans on? If not here is a wiring diagram (below) for the fans and a guide to help you do some testing to see if it is the relay or the fans themselves.

Here is a few guide that will help you get the problem fixed.
