I drained my 02 UK spec corolla.
Tried to refill, but only managed to get about 1litre of fluid in.

Seems I have an airlock in the system.

Any suggestions how to clear it please?

running the engine has no effect, the overflow tank remains undisturbed.

TIA Dave

Most cars have a "bleeder screw" near the thermostat or the watter pump or both...Check a repair manual or ask a mechanic where it is, if not you might have to drain it all out or have it purged at a shop...Good Luck...Radd Guy...

Are you filling the system from the overflow tank or have you taken the rad cap off????

If you have removed the rad cap and filled the system and you want to bleed any air from it you can squeeze the upper and lower rad hoses with you hand to push out any air that may be trapped ( or as metioned in the other post you can use the bleed screw if equipped).

If you are trying to fill from the overflow tank it may not go into the system directly, it's really only used for the overflow of coolant if overheating, and acts as a small supply if coolant is lost.
When the coolant level drops the system (rad and eng only) will take in (syphon) from the overflow resivoir to replace any lost coolant.

Hope this helps you out

park facing uphill on the steepest damn hill you can find. steep enough that the radiators higher than any other part of the coolant system rev the engine a bit with the heater on full blast (temp not fan). turn it off and add fluid then. OR take a coke bottle and cut the end to a size that will fit in the radiator fill hole and seal halfway decently. fill 'er up and turn the engine on (preferrably on an uphill again).

or just go to a shop to get it done.

...any bubbles will go to the highest part. doing this is attempting to make the radiator cap the highest part cuz you can take the cap off and fill it up with fluid... called burping the system. maybe its a cressida thing.

Sorry It just seemed funny :) But I can see the logic in your idea :eek: If a car doesn't have a bleeder screw I can see that working and even better would be letting your car run/circulate in that position and after cooling down remove the cap and getting rid of the trapped air ;) ...Good Idea :thumbup: ...Radd Guy...
