I gave you the wrong pump it was the water pump that was changed

That is the engine oil cooler. Don't remove it if you don't have to! There are Orings that would need to be replaced and it has to be squeaky clean to get it to seal correctly. Pour hot water on the rad hoses or cut them off instead and replace.

Sounds like one of 3 things.... (none are good)

Someone made a mistake on a freeze plug and thats the leak.

The water pump wasn't installed properly, leaking from the base.

The block is cracked near the water pump.

As for the smell of fuel..... something was not re-installed properly and you have a fuel leak.

Sorry this was not a solution as much as it was bad news.

Either you have made a mistake and do not have a proper gasket seal or the pump is bad. Chances are that if you just installed the pump that there is a gasket sealing problem not a malfuction of the actual pump itself.

when you refilled the cooling system did you put anti freeze back in it if not straight water is not sufficiant anti freeze is a lubricant for the water pump seals which could be the problemit is a must in these newer cars &trucks now it is not recommended it is demanded

If you are changing seals and water pumps that frequently then the problem is run out in the end of the shaft. Could be a bad balancer or bearing. This is a major overhaul, I am sorry.

A core plug may have blown out due to freezing. They are designed to do that to protect the block. I know this did not directly answer your questions but hope it is helpful anyway I hope I have been of help but please do not hesitate to ask if you have any further questions. I appreciate your vote if you appreciate my reply.

Where does the coolant drip from? I had one and only one Cad from this era with the same problem. Turned out to be the recovery bottle cap would let go under operating pressure even though it passed the pressure tester test. Just one of those things.

There's a bleed-hole to warn you that it's time to change the water-pump. Also look around the thermostat to make sure its not faulty.

no, leaking water pump just means it is time to replace your pump. Not continue driving until you get around to it. replace it now. If it is not starting something esle is wrong. Unless you've over-heated the engine.

your pump wep hole, bad pump not pep boys fault :( sorry just need water pump.
