Is there evidence of coolant on the front? Or you're finding coolant under the car and assuming it's from the front of the engine?



There's a number of hoses in that area, so it could be any of those. Also a sensor in a hose. I had a leak from a hose that was getting on the belt so it was squealing during cold starts, but there was very little noticeable evidence on the engine itself. Also could be your valley pan, which I believe will start to weep out through the timing cover somehow (I haven't had this yet so haven't looked into how to track it down).


Personally when I'm trying to track down a coolant leak I'll go through a physically touch every hose connection point, particularly the bottom, to feel for any wetness and/or crustiness.
