I need to drain some coolant out of a V40 2002, where is the plug and is it clock or anti clock to open, I dont want to break the valve. Previous owner has near pure antifreeze and I get little interior heat, I checked it with a new Prestone needle gauge. It has so much antifreeze it wont even register a %.

Ok I found and removed some coolant from the valve, I wish this radiator had a cap like old ones. Do I just fill the expansion tank and it fills the radiator? Do I have to run it while watching it? How much coolant do these 4cil hold, filling an expansion tank has me worried I now have air in the system.
yep, run the motor and slowly add your coolant via the coolant tank....once the level is stable...fill to the indicated line in the coolant tank...drive for 30 min, check level...drive another hour or so, dbl check level...and you should be all set...
the air should purge itself after a bit of driving...cooling, warm up, etc... just keep an eye on the level over the next few days and it should become stable...
thanks
I usually squeeze the upper hose a few times once it's warmed up and that does a good job of getting the air out. After that just check it after a few days of normal driving to make sure everything is ok.
yea, puttin' the squeeze on the hose is a good idea....it keeps the coolant moving around and gets the air moving.....
Antifreeze doesnt transfer heat as well as water, the idiots did have pure antifreeze in it, I put in 3 quarts of water in a 6 qt system and now my heat comming inside is about 20 degrees hotter.

How can a motor blow up from no thermostat, You said it goes through to fast to cool, exactly the opposite would happen, the motor just takes forever to warm up, I used to run no thermostat in a V8, on a 4 in winter it just wont get warm, it wont blow up. Japs use pure glycol? on every can of antifreeze ive read it saiys dont use pure glycol, the motor will run hotter and the trans if the cooler is in the radiator
