Hey people my 94 yota today started to spew coolant from somewhere around the ac compressor truck runs fine but over heats after about a mile. I checked the oil an does not have water in it. I'm afraid the block might of cracked. I don't know a lot about 22re's so i that's why i asked. I cant see where the coolant is spewing from it does not seem the be the water pump an or gasket, any advice offered would be great thanks.

 

Mine started leaking from a small hose that connects from underneath the inlet manifold to a metal pipe next to the block - the hose had swollen up and split, its a "U" shape and well hidden :-

Good call you where dead on. Thanks you did not lie when u said it was well hidden!!!!

 

It was the only hose I hadn't replaced!, I found it by looking at an assembly diagram in the manual - I never knew it actually existed till it split.
