So few are as responsible. Hat's off to ya. And that wasn't a tongue lashing.I don't understand. Just drain the radiator and not the block ? I thought the idea was to get the crap outta the block ? Incidently I was going to back flush into 5 gallon pails and drop off at a recycle center. But thanks for the tounge lashing anyway.
X2 If I was concerned about the coolant left in the block, I'd just get the back end of the car up high and let it drain...no way I'd try going after the block drain. I'm too skeered. But like the Crazee man said, if the coolant is clean in the tank and you're not overheating, chances are what's left in the block is good enough as well with a mix of half new and half what's in there.If your car isn't overheating, and you don't have dirty coolant in the reservoir, a drain and refill is all you need to do. If the car IS running hot and/or you have crappy looking coolant in the res., a flush won't solve anything.
Gonna be difficult with this plan Steve as the thermostat is unlikely to get hot enough to open, so you won't be circulating through the rad, unless you take the stat out. Why not fill it, run it, and empty it a few times. Gonna be as good as you're going to get.Thought of running a length of hose from the drain plug to a tank or whatever then open the plug up a bit, only a bit so then I can start engine and keep topping the reservoir up to flush the system through slowly cos the drain plug will be only be open a fraction.
Sounds a plan or am I just dribbling?!
You'd have to jack it up 90 degrees.....X2 If I was concerned about the coolant left in the block, I'd just get the back end of the car up high and let it drain...
