Around February my radiator cracked and leaked out a fair amount of coolant and the temps got pretty high on the gauge. I replaced the radiator with an aluminum aftermarket replacement, replaced the water pump w/ a NAPA with the rubber gasket. I used high temp rtv along w/ the rubber gasket since there was some corrosion on the mating surfaces (though I sanded it off and it was nice and clean before I installed the pump, it was just for extra insurance). I don't see the pump leaking, but I do see a couple drops of coolant on the bottom of the block near the oil pan, just below the harmonic balancer. I see a drop or two of coolant on the garage floor every couple days or so, but obviously not a major leak. Is it possible when the rad cracked and overheated it would have messed up the timing cover gaskets or is the new water pump a more likely culprit?

There was no coolant in the oil, and it runs fine, doesn't overheat, and isn't blowing smoke, so I don't think the head gaskets are messed up. I'm guessing its a giant PITA to replace the timing cover gasket if it is leaking. Anyone else had a leak there after overheating?

 

Your best bet is to get under the vehicle and find the leak. Use a flashlight to help. Look for an area that might look damp. While it is possible to heat things to the point of warpage, it is more likely you just didnt get a good seal.

I have however, replaced a waterpump that even though was new, still seeped from the seepholes slowly so do now rule the ump out unless you can see the seephole and verify it is dry

 

like he said check that seal leak hole I call it that's on bottom side of water pump If the seals on inside of both bearings are leaking the hole is there to verify the inner seals are good if not on any pump new or used you will get drips from that hole and Coolant could be running down from there

 

was it a new or reman pump? I have seen re-manned ones that are warped out of the box
