Overheating problem
I was hoping to get some advice here. We have a 1990 Acura Integra that has an issue overheating. We had it checked out by a mechanic and we had all the necessary parts replaced. A month later, the car began overheating again, so we took it to a different mechanic and explained the situation and he said we might have a slow leak.
Now we're in a tight spot. One of the pipes connected to the muffler is rusted and falling off, so it needs to be replaced. The work will cost $400, but the mechanic said that there is a threat of the master cylinder going out because of the slow leak.
Would somebody be kind enough to offer their input? I'd really appreciate it.
My question is: Should we pay the $400 to get it fixed? How great is the threat of huge repairs being done (given the information I provided) sooner rather than later down the road?
