[jus_tin]

Driving to work this morn and as usual car was taking a while to heat up. then when it was just getting warm it stopped and now no hot air is being blown around the car. the heater blowers are working but got no hot air! also car was overheating and light was coming on which i couldnt understand why, especially since its so cold and frozen this morn. any ideas people?

Have you got any Anti Freeze in your water? If not this could be a potential problem. Also might have been your thermostat jammed shut. Or just air in the system

haha well its gotta be something to do with ur raditor mate either its screwed or id say more likely needs bleeding as said by saxomaniac

well radiators 2 months old and so is thermostat. have bled the system this afternoon and ALOT of air came out the radiator bleed point. havent tried car yet so will find out when i leave work and drive home. also i havent any antifreeze or coolant in car... perhaps i should pick some up on my way home????

If you don't mind your engine being eaten by water or the water in your cooling system freezing then I personally wouldn't worry about anti-freeze esp at this time of year. However if you have an ounce of care for your car and dont want to be shelling out for a new engine in a day, a week, a month? I suggest putting some anti freeze in.

another air lock...

edit: i'm also a noob at anti freeze... what is the ratio of anti freeze to water??? gonna do mine 2moro and need to know :)

well... i care for my car but not about to jump into bed with it! have topped up engine with anti freeze so my relationship with car wont come to a premature end... another happy ending! :luff:

50:50 ideally for the highest protection :y:

all the antifreeze does is stops the water freezing up in the engine stopping cracks and things in the block. Also does the oposite as it stop the engine from getting too hot hence anti freeze/coolant. Good job you have some in there now though

[stalkah66]

also stops the water corroding the internals of the engine

...lol, and that! :oops:

head gasket mate

Thats got to be the most helpful post i have ever read

head gasket mate

That will probably be the most helpful post in this thread….

The chances that the headgaskets gone are high. If it hasn’t gone already, the temp lights already been on so the heads probably warped and it won’t be long before it goes…

And signs of any leaks? If not then the only way an air pocket can get into the coolant is through the headgasket.

What’s the oil like? Any signs of mayonnaise? Any white smoke out the back?

The antifreeze is mainly there to stop it freezing, hence the name… for maximum protection use it neat. It will say on the bottle what ratio to mix it… usually 1:1 will protect to temperatures that we will never get in the UK so you’re just wasting it…

I've feared my headgasket has been going for a while as car used to get really hot. I then changed radiator and had a new thermostat and now when it goes up to 3/4 and just over, it drops down to half and hovers around there. Oil looks fine, no white smoke and had a mechanic do that gas test thing where it changes the colour of this liquid stuff but that was ok as well. I have got an oil leak onj engine but cant work out where its coming out from. Its not serious just a drop everynow and then.
