radiator flush

Had to relace the radiator...previously had added stop leak. Garage did not flush the system, or else did a poor job. Radiator and overflow have poor color and clumps of substance that looks like butterscotch pudding. Will proper flush correct.

I have always had good luck with using the Prestone Flush Kit. This is the one the the "T Connector" for the heater hose and hooks up to a garden hose.

I've used this kit on multiple vehicles and flush plenty of fresh water through system with engine off and with engine running. You must first catch coolant in 5 gal buckets, maybe 2, for proper disposal, but after that, just let the water run.

Then add coolant to achieve 50/50 mix.

Remember, after you flush and drain, use distilled water or else you're going to have more buildup that you'll have to flush out later.

Don't crap where you eat.
