Hey guys, I'm kinda at a loss here. I have a coolant leak at a very small line that runs from a fitting on the passenger's side of the engine, at a small alliminum piece that actually has three lines coming from it, then the hose goes up and over the top of the engine. It has what looks to be a foam covering over, with a small hose inside. Does anyone know what this line may be?

I believe it's the skinny hose in the cfenter of this picture.

 

Anyone care to venture?

 

Check for a dry and cracked hose. Are you talking about the Thermostat Housing? You could have a leak from that gasket. I and others have had to replace the t-stat housing gasket.

 

Yes, it's the thermostat housing. The hose that comes out of the very top. But it could be coming from the housing gasket itself, blowing back onto the hose. Thank you so much, that helps me a lot.

 

So more than likely it's coming from the thermostat housing?
