I put a new radiator, hoses, sensor, and new water pump on. when i started the car antifreeze was leaking from under the car. did i miss another gasget some where? or did the gasget for the water pump not sit right? all the hoses and drain are tight. is there some where it could be leaking?

Hi Crhjelkrem,
My name is Chuck and I'd like to help you figure this out. I do need to know what model year and engine size you are working on. Also,can you pin-point the origin of the coolant drip? What I am looking for is what area under the car are we looking at? What kind of tools do you have to work with? Do you have a way to pressurize the system to leak check? I will look for your post. Thanks,Chuck

Did you thourorhly clean all debry from the metallic parts before reassembly? A little micro chip from the old gaskets will cause any leak

Only way to know is to take it apart again. Your guess is as good as anyones. Some of these have an inner gasket for the water pump which means there was another unit you need to remove once the pump was off.


If this is the same leak as before then maybe its not the water pump thats leaking. If this is a new leak then you didnt do something correctly.
