Coolant pressure test kit

Where is the heat exchanger located?

 

Well while greasing the truck today noticed small drops of red coolant... Not the best picture put it's that little clamp in the middle of this picture... of course getting to it is going to be a PIA. The clamp is turned so I'm not able to stick a long screwdriver and try and tighten it. It's the clamp that has a screw on it. Located directly above trans. I'm assuming it's the clamp although could be the hose. The hose has that plastic protectant over it so I cant see the actual hose until I get in there. Think the only way to access it is going to be by taking that black wheel cover deal off in the second picture... This is why I always tell people they should grease the truck themselves, you find stuff like this.

 

The hetaer exchange is on the right the part with the screw sticking out or in the middle where that hose with the clamp is?

 

Seems like that would be really fun trying to change. Could that leak at the clamp be caused by the heater exchanger being bad or do you suspect it's either the clamp or hose as I said in my previous post?

 

Probably stupid question... When-if I remove hose-clamp coolant is going to run out like crazy right?
