So I've been driving my DII since I did the head gaskets and I still have a leak. I had thought I got it because my leak did not show when the truck was cold (it leaked before right from the get go). When it heats up though the coolant pours out of the front drivers side of the engine. I see it dripping down the front left corner but cannot quite see where is is coming from. I don't believe it is coming from the any of the upper gaskets.

Could this be from the water pump? How does the change flow once the engine heats up? Any help would be appreciated as I am ready to trade this truck in on Obama's gas guzzler plan.

 

Don't guess, go have some one pressure test the system and make sure.

 

I am going to be taking it in for a pressure test. The leak starts when the engine gets to it's operating temperature. There are no leaks when cold. This is why it eluded me for a few days.

Just so I know how does the coolant flow when the engine is cold vs. hot? Where would the coolant be when it is hot vs cold?

 

It's probably just a matter of the higher pressure when the engine is warm, though there is limited coolant flow through the radiator until the thermostat opens.
Also, an inspection mirror can come in handy for seeing things in out of the way places.

 

Check the throttle body heater plate.

 

No it is not from the top of the engine I replaced all those gaskets. I'm thinking it is from the water pump or the gasket from the front engine cover.
