I wouldn't recommend "power" flushing your coolant system unless it is absolutely necessary. My car was overheating, so I figured I would have my system flushed out to see if that would cure the problem. After I had mine done, my heater core went. It turned out that I didn't need the flush after all. The problem turned out to be that my rad cap wasn't maintaining the proper pressure

BEST way to clean a known plugged radiator is to bring it to a radiator shop and have them disassemble and "rod" it. Howo do you know it is plugged????

I like prestone super flush to CLEAN the system. It will not clear blockages or eliminate years of buildup from neglect.

a power flush is the shop draining your coolant and sticking a garden hose in your radiator...don't bother with that crap...

I change my coolant 0nce a year, it is not like I don't take care of it. The rad is only 4 years old to. It has a hard build up of some white stuff in it and i am not sure what it is, is there anythign I can put in to prevent it.

best stuff i've used is this two part prestone stuff we use at work for the bulliten on the blazer's with coolant turning solid. works excellent. but as has been said, if you have any leaks it will be very noticable after you flush it.

can you find out a exact name for it or a part # zippy, thanks

Best way to flush is to install a flushing T in your heater hose which allows you to back flush the system. Follow instructions on package. Regardless of the flushing agent used, the hardest part is to make sure all of it is out of the system, meaning alot of final flushing with water. To minimize further scale deposits, mix your antifreeze with distilled water instead of tap water. You'll never totally prevent the white deposits from forming. I can't remember for sure, but besides being scale deposits, it could also me solder bloom, which is a reaction of the coolant to the solder in the radiator.

Mine was all rusty and thn I put some flusher in it, let it run for a while so I knew it was out, then I clenaed it all out and it was perfect. Just remove teh upper radiator hose, take the cap off and run the engine wiht a hose stuck in the radiator carp hole. Dont worry about it overheating, it actually runs quite cold. But you do want to heat the engine a bit. Wait till you can only see clear water coming out of the hose. The nput your flush in according to the directions and it should be good as new and run much cooler.

Black,

Zippy and FJK have the right idea. Prestone used to market a kit containing a flushing 'T', acidic cleaning agent to remove the scale, a neutralixer to keep the acid from destroying the gaskets and castings, and fairly explicit instructions, which inluded removing the thermostat and reverse flushing with plenty of water. If you have excessive mineral deposits, follow FJK's advice and remix with distilled or deionized water.

FJK - looks like Jefferson is a wash today. There is a chance of T-storms with light hail moving right through the area later today. Seems like this happens about every other year...

Forgive me guys for using this post for a little note to Vader.
Hey, I was there at 7am & let me tell you the dogs are barking now. I forgot how they changed the fairgrounds & though main building....????.. that leaves too much to interpretation. I probably should have said "Sheep". Well, maybe next time.

i can get the part no. monday.

Did you get the part #?

[ use distilled water with your antifreeze mix this will help prevent depostits.
