I've got a 1996 SC300 with about 94,000 miles on it. Lately I've been smelling burnt coolant. I got the system pressure tested and no leak appeared. However, I seem to loose about half the reservoir every 100+ miles. I think I've found where the system is leaking and have it isolated in the photos attached. I was looking for some guidance on what this area was and suggestions for a fix. It might just be the clamp on the hose but I would appreciate some of your thoughts. The first picture is to show the area. The second is a zoom in on the area I believe is leaking (its just behind that tubing). Thanks!

This hose is going to your heater valve if i'm not mistaken.Try to find where the coolant is leaking from.If its from the hose then you might be able to cut it a little so it will fit snug.If not ,then you can get a piece of hose from autozone and couple it up.

Yeah I would say the same thing. Get a new piece of hose and a new hose clamp. The hose might possibly leak again if you try to reuse it.

Upon further discovery the coolant leak may not be coming from the hose and/or clamp. I trimmed the hose and put a new clam on that seems to be holding tight. The seeping/leaking looks like its coming from the underside of the bell shaped part in the center of both pictures. It looks like that is what I need to replace. Can someone tell me what that part is called?

It is either a coolant valve or a actuator I forgot the actual name the dealer calls it. It is either or one of those names. Try to find one at a junk yard cause those things are kinda pricey if you get them from the dealer. That ro you can get it on CL I would do that. Better luck on here then going to a yard.
