Okay here's the ordeal. If i leave my jeep for a few days without driving, say 2 or 3 days, i will start to have coolant leaking down the oil pan from what looks like the bottom of the crankshaft pulley.
I cant actually tell where its coming from, i can only see in a limited space. Its not a horrible drip, but a small puddle every few days of not driving.
I replaced my waterpump and t stat before Christmas. I used RTV on the seals as well. im not ruling those out, but i cant see the bottom of the waterpump to actually tell or not.
Someone mentioned a freeze plug? but i would like more input if possible.
When you installed the new water pump did you clean all the gasket/dirt off of the bottom mating surface super good where the oil/grime accumulates above the timing chain cover? Did you install a new water pump inlet tube as can be seen in the below link or just use the old one? Sometimes the old ones are hard to seal correctly and can leak. Also make sure your hoses are tight.
thank you, yes i did clean the opening well, chisled the old gasket off and used acetone on a rag and cleaned the whole area well. unfortunately i had to use the old hose inlet tube, as the were out of stock for new one. I guess ill just pull the fan off and take a closer look.
although i find it odd it doesnt leak after i drive it. Its just after 2 days or more of sitting.
YW and if you can remove the fan clean everything off with spray brake cleaner then you may be able to see where the coolant is coming from after sitting. They also sell a UV marker you can use or eventually the coolant should leave a trail/residue where it's leaking.
I've also had to use the old inlet tube on new/rebuilt pumps before and supposedly on some there's an o-ring down in the port which needs replaced. But after putting gasket sealer on the threads it seems like they don't always bottom out but haven't had them leak after doing this. And I do use gasket sealer (Ultra Black) rather than regular RTV on any coolant mating surfaces even with a water pump gasket.
