Hello and Welcome to justanswer..
If you are having real trouble clearing an air lock - switch the heater control to Hot - then drain the system completely ..
Then raise the front end of the vehicle by at least 18" -
Then undo the vent / bleed nipple/s..
Prepare a 50-50 mix of antifreeze / coolant and water... make sure its a 50/50 as that helps with cooling ..
fill the cooling system - and as you pour it in - slowly
- Do not be tempted to rush it ... pump the top and bottom radiator hoses all the time that you are filling
That dispels air locks - When the system is filled up to the MAx mark - start the engine and allow it to idle - while still pumping the hoses
- and bring it up to temperature...
You will see that the water level drops as the thermostat opens...
Then you need to top the system up - again , slowly - and make sure you dont scald yourself when opening the cap...
At this point you should top up with warm to hot water...
Fill only to the max mark - no more...
Then drop the vehicle and run it until the fan comes on. Recheck the levels and all should then be well .... Dont forget to close bleed nipples.I Since
rely hope I have helped you - Please ask me if you need more help..
Kind Rgds, MIKE
