switching coolant

[shojuan]

I've done it that way on most of my vehicles throughout the years. That's the way Dad taught me. And like Dad, I've had a collection of unused prestone backflush kits collecting dust.

Has anyone successfully installed the Prestone flush kit in the heater hose of the SHO? I put one in my truck and its great; not much room in the MTX SHO because the engine is so close to the firewall.

When a heater hose started leaking at the block in July, I had to pull the pipe out so I had access to a heater hose at the firewall. Those one-way hose clamps are evil incarnate! It took me a good 45 minutes each to destroy them without damaging the rubber hose. Anyways, back to the story. I had the metal pipe seperated from the heater hose so I temporarily installed a prestone backflush kit and had at it. When I was done I filled a 5 gallon keg with distilled water and pumped this through the backflush connector to get rid of as much hard water as I could.

I think the key is to get those crappy clamps replaced with good old fashioned stainless screw clamps, do your cooling system maintenance often enough so the hoses don't bake to the pipes, use a little silicone spray to install and remove hoses, and then you can get the hoses off easily whenever you want. I plan on saving an old heater hose to splice in a backflush T so I can do a temporary install whenever I want to backflush. I know you can leave them installed, but whenever I've replaced nasty old hoses with nice pretty new ones I've always felt it would be cheesy to have the prestone kit installed. Besides, it's good exercise to make sure those heater hoses will come of easily every now and then. When they bake for a decade plus they can be a challenge to remove.
