Today is one of those days I want to stick a "For Sale" sign on my '66 and say "To hell with it!" Here's the deal . . .
My car has a LONG history of engine scaling problems that has led to constant, reoccuring overheating. I have owned this car now for four summers, and I just put in the third radiator since I've owned it (and I had one of those recored!). The last radiator was installed a month ago, and in the 90 degree weather, she ran cool. I also added an overflow tank for the heck of it as it's a daily driver, and I've been careful to make sure it was never low.
Well, today I was picking up my other car from the shop with my wife when I noticed coolant all over my window. I checked the temperature gauge and sure enough, she was hot. When I got home I popped the hood and noticed that the overflow tube had popped off its fitting at the radiator neck, and the overflow tank was completely full. When it cooled down enough to check the inside of the radiator--you guessed it--there was a bunch of engine scale/rust that had accumulated. Tons of it . . . AGAIN!
Before I installed my present radiator about month ago, I used Prestone acid flush and ran the motor for 12 minutes, then drained it. Then I added some anti-scaling coolant and additive to help prevent it from happening again. So much for my efforts.
So now what? Some tell me to remove the water pump and flush out the motor that way, but that won't really loosen up and flush out scale will it? Others say to remove the freeze plugs and flush it that way--but is that really any different than flushing it at the water pump?
I really don't know what to do. I am going to have to have this radiator rodded out as it is, and the car is now undriveable AGAIN. I really need some HELP!
