i have no idea where it comes from. the water pump was replaced with a brand new one like 6 months ago. the thermastat was just replaced last month. new gasket as well. it semms to leak up front like naer the radiator, hoses are fine any ideas where its coming from would helpthanks

 

Could have a hole in the radiator. The easiest way would be to buy the dye for the coolant and go back over it with a black light to find where it is coming from.

 

ill give it a try

 

could be a cracked radiator. or the gasket for the water pump might not have been installed correctly. If you went with a re-built pump it could be bad already. Dont discount somthing just because its been recently replaced. Bad parts do happen

 

Get out a flashlight and see if you can tell where it's coming from for sure. Mine was leaking pretty good after I did a water pump and it was coming from the timing cover gasket.

 

that seems alot more logical cuase it was coming from up top and at frist i thought it was the thermastat housing but it was good so ill give it a look[:-]

 

pressure test the radiator w/ a pressure tester, you can do it with the truck off and then you can hear and see right off the bat where the fluid is leaking, I had a pinhole on a rad hose that I didn't see until I pressure tested the system

 

check the hose behind the alternator

 

found it, that housing for the thermatsat was loose from the shop.

 

Mine is leaking at the radiator / top radiator hose connection. I believe its because they poked a hole in teh hose to tag it. I am going to try and cut about an inch off of the end of the hose and reattach and see if that stops it.
