Hey guys, i noticed a small coolant leak a few days ago in my 95 gsr. It only leaks after the car has been driven to operating temperature. If I drive the car for 15 mins to get it warmed up and then park it, I can look under the car and see a steady drip every 2 secs. The dripping will stop after the car is cooled down and will not begin to leak again until the car is warmed back up. It olny leaks a small amount of fluid at a time, maybe a few ounces. I drove the car around and then took it home and immediately jacked it up to get a look underneath to see if i could spot the leak. It seems to be coming from under the intake manifold. There is a hose that connects directly under the throttle body and goes behind and under the intake manifold and connects to an elbow. I have isolated the leak to this area however i cannot find the exact spot when the coolant is leaking out. I have circled in red the areas that the leak is coming from. Anyone have any ideas what could be causing this. I inspected the hose and there are no cracks and i also replaced the hose clamps, but no better. Also when the hose goes from the throttle body to the elbow connector what is that part that the elbow is coming from called. I noticed that there seems to be a gasket in that piece, wondering if that could be the culprit. Thanks a lot.

 

its the hose to you IACV

below your IACV, there are 2 hoses. those hoses carry coolant. make sure you have the clips to hold them tight onto the iacv

 

they are a pinch style clip not a screw one

 

My car had one of those hoses under the IM start a small leak, then progressively got worst until I could diagnose it as the reason I was overheating. Funny how 14 year old hoses and pinch clamps don't hold up, lol. Replace them all while your there. 8mm hose.

There is one bypass hose that is in a U shape, I bought if from the dealer $4 because ordinary hose would just pinch.

 

I inspected the hose and couldn't find any holes or cracks. And I replaced the hose clamps just to be sure. Still leaks. Could the IACV be the culprit, do they have a common problem with coolant leaks?

 

common problem on most tegs that i have owned or others i know have owned as they get to some of elder years. more often then not its a hose not ur iacv
