Had a puddle directly underneath the front of the engine, behind the radiator, so am thinking it's the pump. It's dripping down the front of the oil pan, didn't see any coolant on the rad hoses, will look more closely after I clena it up to see where it's coming from.

Anyone had problems using a NAPA waterpump? $51.99 is the cost. If not, which one from Fastlane, Laso for $80 or Geba for $51.

Anything else I should change while I'm at it? Thermostat, etc?

Also, I recently had it in to my mechanic for AC service, and they told me my fan clutch is shot, and recommened I replace it. Any suggestions on where to buy? Fastlane?

Thanks,

Adam
