overheating

pretty certain i have an airlock, engine is overheating, blowing cold air. then will blow hot air for a while and temp will drop, then does it over again in a cycle.

how do i bleed the system is there any easy way, read about people doing it but no one saying how

pos. blocked heater matrix??

Car cold,take the rad cap off and start the car, switch the blower on to full and heater onto full, get yourself a nice big jug for adding the water into the rad.

keep the car running at a fast idle and eventually the thermostat will open and thats when the water will be cicurlating fully, you will start to get bubbles (this is AIR) coming outta the top of the rad just keep adding water in and eventually you will remove the airlock.

it takes a while to get the airlock out,keep checking the heat from the airvents and they will eventually go very hot.

And be careful as doing this can get you a nasty burn.

Replace rad cap and check expansion tank and take car for a run and check levels later .

Nice one andy. Dont have a prob with this but a very detailed and helpful walkthrough

Oh....just to be picky, how do you take the rad cap off twice

you take it off...put it back on and then take it back off again..and then you say GROUNDHOG DAY IS HERE!! .
