Ive noticed for the past several months that I have to fill the reserve tank every few weeks. And yesterday she overheated. The ratator was like half full. But when I inspect the hoses I dont see fluid dripping or even steam for that matter. Any tips on how to pinpoint where the leak is? There is some build up of crud on the end of a heater hose. Could that be where its escaping?

 

I posted something about this a while back. If you have the 2.8/3.1 theres a coolant tube under the throttle body that connects to a black tube with 2 rubber hoses coming out and going into the intake. This is probly the cause. It was on mine anyway. the part is 8 bucks and change from the dealer. ask for the intake coolant tube, the parts guy knew what I was after, It seems that the dealer I went to replaces 3-4 of them a week. The orginal part is aluminum and the replacement is a steel alloy.

 

If that is the problem then do a tb bypass and be done with it.

 

that wont fix it
this part does not flow into the tb it flows into the intake .

 

Oops read that one wrong.
