The fan relay replacement solved the problem.
Issue solved with that hose replaced. It was a hose under the engine somewhere, he doesn't know the name of it but he used that tool where it blows air into the coolant intake cap area and he pinpointed the air coming out of one of the hoses.
Car is fine now.
Well, what else the mechanic is going to replace?Problem has returned, same issue.
This.The cooling system needs to be overhauled.
Probably a little leak and not gushing out on the floor. If you don't see a puddle on the floor after parked it, then the little leak from these pipes cannot cause the overheated issue that you reported.He said they are leaking.
It is a hard pipe and not a soft rubber hose. As I said the slow leak (water gets evaporated because of the heat in that area and on the parts. Thus the leak can be hard to pinpoint) that didn't dump the coolant on the floor would not cause the overheat. Hopefully after replaced the #8 pipe the mechanic bled the system properly and this fixed the overheat, but not the old pipe with small leak that caused the overheat. (Remember you had thought the problem was fixed, twice, and it came back.)The main one with the leak was the number 8 house in the diagram. Its interesting because when that one leaks, the water gets evaporated because of the heat in that area and on the parts. Thus the leak can be hard to pinpoint.
