Aux Heater

[DaveM]

Further to my recent thread on the the Aux heater packing up on my 2.8 V6 a couple of weeks ago.... it now has burst back into life, but only intermitantly.

 

i.e. start up, and after a couple of seconds, the drone turbine like pump/fan starts up. but then again, sometimes it doesn't, (it used to start up every time)

 

one thing though, you guys said the gizmo was positioned underneath behind the driver seat. Well there's a lump that looks like some sort of pump/heater in that position, in fact it looks like a mini alternator ! (I know it's not, but it gives you an idea). it also chucks off some serious heat !

 

The main turbine/fan/pump like noise emits from behind the under engine cover underneath the front of the car. I assume this is the additional water pump that pumps the aux heated water around the engine thats making the noise.

 

but then again, what do i know !?!

:P I'm still iffy on this petrol aux heater of your's BUT; the terminals of the pump on my old allhambra corroded and fell off when touched for examination 1 day :wacko: (it's positioned in a place that can catch salt etc)

 

" it also chucks off some serious heat"

 

:P It could be that this motor has siezed :angry: When my home central heating recirc pump siezed due to sediment - it still drew current and became EXTREMELY hot : IT BURNT MY HAND :P i got it running again by rapping the adjuster plug with a hammer (it loosened the sediment) IF your pump IS pumping petrol - and has siezed it MAY draw current during temperatures low enough to activate the heater :P AN EXTREMELY HOT PUMP WITH PETROL IN IS SCARY :P Cup your hands around it next time it's cold enough to activate - if it burns.....be afraid - be very afraid :wacko:

 

bear in mind that the temperature has been fluctuating recently :wacko:

Is that the small thing tucked up at front of the fuel tank? - I thought it looked like a cut off valve - I am also most miffed that electrical gear is just hung open to the elements - its already quite corroded although I keep it in the garage 90% of the time. Hope its not expensive..
