Hello all, new member here. Have an 2001 CL Type S that I am having coolant temp problems with. After a lot of reading(seems to be a very common prob) I changed the temp sensor and am now changing the thermostat. Top hose was much hotter than the bottom, so I figure this is the problem. After taking off the housing, I see a lot of build-up, yellowish hard substance in the housing, which is worrying me a lot. Coolant was changed out very recently. Any ideas?
