PrestoneAF-KIT Flush 'N Fill Kit

Only work if you have an old car with a "radiator cap" and an American style garden hose end. Very disappointing, went straight in the bin.

Had a buddy with an old vehicle and a radiator in bad condition to match. Put this in line, got a lot of bad stuff outta the lines. Refilled with new coolant mixture & it's running better!!

Used this product to do a full system flush on my 2000 Buick LeSabre equipped with a 3800 series 2 V6. I cut into the heater hose near the back of the engine, slipped the adapter on, opened the rad cap and hooked the hose up to the adapter. It worked great and flushed all the old Dex-cool coolant out. I even managed to refill some of the system by pumping some of the new coolant into the adapter.After everything was finished and the rad was filled with new fluid, I put the cap (that came with the kit) on the adapter and have left it since. It's been over two weeks, have had coolant temps as high as 230 degrees, no sign of any leaks whatsoever from the adapter, it appears to be holding up great. If you have the general know-how and a few basic tools, would definitely recommend. It will make future flushes and refills far easier and faster now.

Myself and my brothers and friends have been using these for many years. There is no better way to flush your engine's cooling system. Just run a flushing chemical using it's directions, then flush through the Prestone T system. It will remove rust and corrosion and leave you with a clean system. Then just drain and use your preferred coolant.

Super product

It was easy and worked perfectly with no leaks.
