Radiator Reverse Flush

[pakers]

Anybody have a opinion about using the Prestone reverse flush on my
1993. Also the best place to install the flushing T.
Thanks

In most of the vehicles I have owned in the last 20 years (stopped counting at 15 LOL) I have put the "T" in one of the heater hoses so that the heater core would be flushed out at the same time. It has worked well for me. I just wish one of my current vehicles (1997 Venture) had the heater hoses in a better place instead of out of sight, and inaccessible.

Can't you just switch them at the firewall and do the same thing?

replenishing the coolant should suffice.using the high pressure flush could dammage the cooling system.

Beware; before attempting to flush a venture:The venture has a radiator that is lower than the rest of the engine. This makes it trickier to flush or replace coolant. Air can get trapped in the lines because it can't get out the rediator cap as in most cars. This can cause the heater or other parts of the engine not to recieve coolant correctly. The owners manual said it could actually damage the engine.
I have been told to do this proceedure from a mechanic:There are 2 air bleed screw valves about 1/4 inch in diameter. One is mounted in the pipe at the water pump which goes to the heater and the other is on the top radiator hose pipe on the engine, near the thermostat. After replacing coolant put the cap on the radiator and you run the engine until the top hose is hot to open the thermostat. Then open these air bleeders until a little coolant leaks out. You likely will here air escape a little-this is good. Once the coolant is positively trickling out, seal them down again.The system should be void of air now.
As far as the flush kit goes, I decided not to risk cutting the heater lines since they are so far back in the engine area. However, there is a short section of hose next to the water pump that connects to the heater return line. I disconnected this and with a few extra pieces of hose and pipe clamps, used it as point to tie on a flush line. It worked well for me. Hope this helps.
