Put what ever you like in the radiator but it won't fix your problem and it will mor than likely cause you even more grief. Bubbles in the radiator indicates a head / gasket fault and the only fix is to pull the head.

There seems to be an air pocket or no antifreeze in engine block. Try this method disconnect upper radiator hose and pour water directly into hose down into engine block until it full. when its filled reconnect hose and fill up radiator. as the vehicle warms up open bleeder valve on the thermostat housing and release air from system. open slowly and BE VERY CAREFUL WATER WILL BE HOT, bleed until you get a steady stream opening and cosing valve. However if all of this don't work. You may have a bad pump. Good Luck

ok, its time for a radiator flush. there is major sludge in the internals of this radiator. Make sure the thermostat is in the correct position as well. I've seen many cars come into my shop with the thermostat inserted backwards.

yes it can mix, also check the timing cover for rubs from the timing chain. this is the common problem with 22r. many mechanics will tell you its the block but they are just trying to make money.

The car's engine is overheating !
Its not because you forgot to fit in the thermostat there could be other problem, like tht of the water pump, radiator clogged up, cooling fan.
You have to check them all.
Was there any problems before you pulle out tht cylinder head?
SOURCE: Water not staying in Radiator
yes, not having an overflow reservoir for your radiator will cause you to lose water. As your engine warms up the water expands and creates pressure in the cooling system. When the pressure reaches a certain point(usually about 15 psi.) the radiator releives the pressure by releasing water into the overflow tank. When the engine cools back down the water shrinks pulling water back into the radiator from the overflow. If there is no overflow, the everytime the engine warms up on a drive water will be lost and not recovered on cooldown.
