I have a 1995 SC400 with 160,000 miles on the clock. I have a coolant leak in the left front engine area that I just can not find. I can see the coolant dripping down near the oil filter housing and running out on to the ground. It is coming from somewhere above that area. I have checked the hoses and pipes, as best I could and find no leaks top side. I removed some of the plastic covers and the cover from the left bank timing belt cover. I see what appears to be dried coolant in the area but see no leaks. It appears I can't see behind the left timing belt/cam gear without major disassemble. Can anyone help before I start removing large pieces parts?
