why does my mgf take ages for the heaters to warm

:frosty: does anyone have a problem with their heaters taking 2 weeks to get warm. The car takes a lifetime to warm up. If so is there solution ???

Sounds like the heater needs bleeding or the heater control tap has packed up. The heater normally comes on stream very quickly.

Bensewell had the same problem with his a while ago.

I have a suspicion that your thermostat may be stuck open.

my tf does the same i have tried bleeding the system 3 times now, it does get hot but takes about 6 miles driving to do so but my mk1 is pretty much hot by the end of my road

Some people in the past have put a small hole in the thermostat to allow continual flow to protect against thermal shock when the thermostat opens. One big side effect of this is it takes longer to warm up.
I'm not saying this is a good idea, but who knows what previous owners have done?

If i sit in one place it will warm up quicker but if one the move its just warm at best. The temp gauge is just above 0 when on the move. as soon as i stop it starts to climb

All possible reasons above.

First thing to do is remove the ashtray! If you put your left hand in there while seated in the driver's seat, you will be able to feel the heater pipes. Bottom one in in and top is out. After running the car for 10 minutes test these pipes for heat.

If the system is working properly the bottom pipe should be almost too hot to touch and the top less hot.

If the bottom one is hot and the top one cold there is no flow through the heater matrix. This could be the valve stuck shut, or air in the matrix preventing flow.

Let us know what you find and we can go from there.

That definitely sounds like thermostat.:yesnod:
It could explain some of your idling problems also.

Bottom is really hot top is hot but not as hot as bottom.

Is your heater blowing hot now?

Sorry for the delay. the heater warms up when your parked but never gets really hot and as soon as i drive its back to bordering warm
