Well, the cleveland is overheating again and when I checked the radiator it had some fins clogged with chunks of dirt. Is there something i can use that will dissolve or clean the radiator and engine? thanksAldo

A radiator flush will help clean deposits from inside the block -- or so the makers claim. But if your radiator is really clogged, you can't beat removing the top and bottom tanks, and running it through with a long, thin metal strip. Takes time, but it sure works. And when all the crud is out, make sure to use distilled water in future, especially if you've been using hard water. That stuff will clog it up again fast.

Take out the radiator and take it to a radiator shop. Have them rod your radiator. This will clean all the crud out of the radiator. While the radiator is out, flush your engine block. This will help clean out all the water passageways. You will need to remove the thermostat to flush the block.Dave & Terri ------------------ Poison Ivy (Dave's) '65 Fastback Modified 289 4V, C-4, dual exhaust, styled steel wheels, rally pac, A/C '02 Explorer XLT, Black, 3.73:1 limited slip, class III tow package!

Make sure you weigh up the price of a new rad against what the radiator shop will charge. Around here most of them want beaucoup bucks for rodding (depends on how much of the work you do yourself) One of the biggest benefits of playing with mustangs is that they are popular and the parts are pretty cheap, take advantage of that where you can. Most new rads wont cost you more than 150 bucks, the rad shop could easily charge that for the cleaning job. Depends if you are keen on keeping it truly original as well.

Be careful with radiator flush if your engine block has never been flushed. I used a heavy duty flush and it broke loose a lot of junk from my block and it lodged in my radiator cooling tubes. I removed my radiator and had it rodded then flushed my block like someone suggested. Engine cooling system is just about perfect now.

I agree with Indy, I'd buy a new rad, and flush well before putting the new rad on. Use a 50-50 mixture of coolant/water , get a new cap with the new rad and use a new 160 thermostat. Also, get a rad overflow tank if not already equipped with one. I cut the hose which lies across the top of my 65 289 and added an insert and cap so that after flushing, I could REALLY clean out the acid after flushing with the garden hose. That way, you won't have any residual acid still left in the system to break off additional rust or rot out your heater plenum.
