Draining coolant and refilling in CJ 2.0 litre

Postby brislancer » Thu Jul 15, 2010 7:52 pm

Looking at doing a coolant change and refill on my ES 2.0. Looks like there is a butterfly shaped bung on the radiator, but was wondering if anyone had done a coolant change on their car. Am asking if anyone knows if there any bleeder screws in the head or block to undo for air release when refilling system?

Any help much appreciated!!!

Pretty sure there aren't any bleeder screws, just use the butterfly one and then remove the hose at the end.

You do need to make sure the coolant is up to temp though so that the thermostat is open

When we did LZY_EYE's car we only used the butterfly bleeder on the radiator and had no problems with air pockets

The main thing is there is enough active ingredients in the cooling system. From memory, system capacity is around 7L. Slightly different for turbo or 2.4 models. Consult owner's handbook to be sure.

Say system capacity is 7L and you are running 33%. You will need 2.3L of 100% concentrate or 4.3L of 50% premix. If you can only put 3.5L of 50% premix in and you are really worry about it, you can reduce the change interval proportionally. Which means reduce the change interval by 25%.

BTW, don't forget to turn the AC knob to hot to release the coolant from the heater core.

Do you have green or blue coolant and what year is the car?

Might be a silly question but opening the drain plug whilst hot and under pressure would seem problematic. Did you wait for it to cool somewhat or take some special precautions?
Without knowing the interior of the engine, if the drain plug is at the lowest point of the cooling system, I would expect the coolant to drain from both sides of the thermostat, even if it were closed. Can anyone confirm or dispute this?
