I bought a 1993 Loyale. Body is near mint condition. The previous owner had some cooling trouble just before I got the truck to pick it up. Long story short, the headgasket/s are blown. I am re assembling another known good EA82 engine that I already had from another one of my cars. But I need the intake from this 93 since it is the only California car I have.
So I remove it, and the coolant passages are partially coated with crusty orange crud. Some flakes off, some is very stuck to the aluminum. I can't get at every passage - so what to do?
What could this be, I've never seen this kind of crud in a cooling system. What might remove it?
I'll have to check the radiator and the heater core before running the car!
