Question about Cars & Trucks
Would like to know the correct procedure involved in flushing the cooling system. i know the mixture is 50/50,but am not sure how to flush all coolant without overheating the engine.
All I have done for 49 years is drain the radiator & then
refill with 50/50 or 60/40
If you do every 3 years your okey
People are obsessed with coolant & trans flushing,why?
You do not have the engine running until you have it refilled
then add as the thermostat opens & fill the degas bottle

Use the heater hose to back flush the cooling system, they make an adapter kit for what you are doing, it's very inexpensive, it goes in the supply line to the heater core, that is the larger of the 2 hoses.

Preferable to flush as much out as possible to get rid of the old stuff and can be done at home by undoing the heater hose at the fire wall and using the garden hose to force water through until it comes out clean Dont turn hose on full blast as it will spray out over everything build up to it so it doesnt make a mess.Make sure the heater is in the on position so that water comes out the pipe you took the hose off.Either way though it will still be ok to just undo the bottom radiator hose as the majority of it will come out.

hello your intake gasket is most likely leaking internally into your engine.pretty common problem.the plastic and silicon gaskets get weak over time.

your radiator has a pecock on the bottom of it screw it out then you can run water through a hose behind it once it stops draining to get any residue out as far as the engine youll never truly get all of the old coolant out without tearing it down and putting it back together so flushing the radiator is just fine.
