Booster Heater Logic (sorry To Have To Ask...)

[Ex-Galaxy person]

Hi,

 

I've read loads of posts on this and done some searches - just want to make sure I've got this right.....

 

Booster heater is supposed to come on when:

 

Ambient air temperature < 5-10 degrees or engine coolant temperature is below 75 degrees.

 

Is this correct?

 

I ask because mine only comes on when the air temp is cold - it seems to disregard engine temp. If the statement above is correct, the booster should fire up on a cold engine, even in warmer weather...right? In which case, I've got a duff coolant sensor (wherever that is - temperature gauge on dash is working.

 

Sorry to ask this - everything I've read so far confirms the cold weather bit, but not so sure about engine/coolant temp. I've got a 2000 Mk1 Zetec TDi.

 

cheers,

needs low ambient temperature AND cold engine to fire up.

Cheers - that means mine works as it should. :ph34r:

yep, mine seems to kick in at ambient temp 10C or below when the engine coolant temp is 75C or below.

 

both must be below the temps given,

I've got a 2004 Galaxy and I think there is a more complicated algorithm built into the computer. It always comes on first thing in the morning but after that there seems to be a time limit on warming the engine up. So the booster heater doesn't initially power up but after driving for a while and the engine temp is reading approx 50-60 degrees for a while it powers up till it reaches 90 degrees. I had to fit a new glowplug over the christmas period and the ebay seller motorcare online was super at sending it by special delivery so I could keep the Galaxy on the road.
