tysree Posted May 11, 2009 Share Posted May 11, 2009 I have a 1986 XT Turbo EA82T, I'm Wondering how to do a cooling system flush? I herd I need some sort of adapter that will allow me to hook up a garden hose and then I disconnect something else and it will flush the system? what do I do? Thanks:) Quote Link to comment Share on other sites More sharing options...
Indrid cold Posted May 11, 2009 Share Posted May 11, 2009 (edited) I havn't had any luck with the off the shelf stuff since they pulled the real acidic/caustic stuff years back.... I had cooling issues on a Oldsmobile and tried the stuff.. I just finally bought a new radiator, pulled the T-stat (Thermostat) out and flushed with the radiator hoses dangling, got a good flush of water through system/heater core then installed new radiator, prestone 50/50 mix. ........ to answer your question, yes there are adapters that you can cut into the heater hoses.. but to get water to flow through the engine the T-stat would have to removed... or your really not getting a good job of it. The auto-garages have a system that ties onto the radiator cap or hose or heater hose and the car is ran up to temperature, this opens the t-stat and they flush with what ever chemical they use.... but if I have that much into it (shop rate $) I just bought a radiator, new T-stat and that fixed that.... my .02 cents worth Edited May 11, 2009 by Indrid cold Quote Link to comment Share on other sites More sharing options...

subiemech85 Posted May 12, 2009 Share Posted May 12, 2009 after reviewing my pictures, procedure was removed radiator to flush separately and clean fins, re-solder top support NOTICE: '78 BRAT uses 1/2" heater hose garden hose female fitting inserted into heater hose to flush system 1-3 head drain plug removed by plugging different ports, flushing direction can be manipulated flush until water runs clear in every direction switch to PG coolant [D] specific purpose control enclosure cover used to cover weber air filter Quote Link to comment Share on other sites More sharing options...
