I want to flush the cooling system in the cossie and wondered if a good way of doing it would be, to run the car up so it's nice and hot, so all the crap is soft and moving, then take the turbo return off of the header tank and with the engine still running let all the crap flow out and just put fresh water in the tank to keep it topped up.
Would this be a good way of doing it or a waste of time?
The reason I thought of it is its how you do a hot flush on a central heating system at home.

The system is currently drained so a lot of crap will already be gone, and I'm going to fill it up with fresh water now.
I've also ordered some dei coolant flush but thought I'd do this to get rid of the majority of crap first then put the flush in and do it again later.

What do you think?

I thought it was a bad idea getting the engine hot then putting cold water into the engine.

50% water 50% distilled vinegar. Fill it up, let it warm up, drive it for 15 mins, drain it. Watch the orange tango come out. Fill with antifreeze. Have a cuppa.

I did think it might not like me putting cold water into a hot engine, there's no reason I can't use hot water from the kitchen sink tho so will be filling it up with water that's nearly the same temp.



Another reason for doing it this was is that my system is a bitch to fill properly and not airlock. And by just taking off the bottom rad hose it doesn't drain fully so I have to take a hose off by the engine and it makes a lot of mess, by pulling off the turbo return I can just extend that hose to outside the car/garage and make no mess.

The turbo return is right at the top of the engine, so it'll be pretty useless. Best way it to take the rad out and flush it with a hose.
