Faults:

Constant overheating problems; I've replaced the thermostat, radiator cap, hoses, water pump and I fitted a three core radiator. I even had the head rebuilt., and I still have problems.

Since the three core radiator went in, it has been much better, however she still wants to overheat.

I feel the Problem must be in the block; does ANYONE know anything about these types of problems that these engines have. I had another Crown ten years ago with the exact same problem, and I ended up replacing the engine and the problem went away. I do not want to do that again. HELP.

General Comments:

When I bought this car, the previous owner was very old and never put coolant in the car. He never drove her far.

When I got it I put in some good quality coolant and started this chain reaction; all this rust started appearing in the radiator, and it got to the point where I had to pull it out every day to flush the rust out of it, then refit it, once the rust stopped showing up. I had the system flushed and then replaced the radiator, since then no end of problems. I drove the car across three states when I picked it up, not a single problem till I put the coolant into the engine.
