Heating
« on: 08 January 2011, 14:32:21 »

Hi All,

I have an ongoing problem with heat (or lack of it!)

The car is taking a long time to warm up, while in traffic it will slowly warm until the gauge is just below the 90 mark, once moving it will drop down to the stop again. Possibly related, the passenger side will blow warm air but the drivers side won't. It will vary between freezing cold and luke warm whereas the passenger side will blow warm air. When the air is aimed at the demist it is coming out warm on one side and cold on the other.

This is on a 2.5TD mini f/l, it DOESN'T have climate, just the four rotary dials.

I've put in a new thermostat! (Although the old one moved correctly when placed in hot water so seemed to be OK)

I've dismantled the centre console, from the back of the drivers heater dial there is a flexible push rod that operated a flap at the bottom of the centre console, this appears to be working fine, has the same range of movement as the passenger side.

Finally, the viscous fan has been removed but the engine never warms up enough to need the electrics.

I'm running out of ideas now, about to try a matrix flush but not sure how/if this will help? Does anyone know how the air is routed through the matrix to keep the two heating zones seperate?

Any more ideas please, whilst I did enjoy the drive down to Mid Wales after Elite Pete put my new wishbones on (thanks again Pete!) I did arrive with very cold toes  :(

maybe the thermostat., and need a flush out as well.
to flush out the rad you need to remove the pipes in engine bay and then put hose pipe on one side and keep going from one pipe to the othere untill it comes out clean water, then leve to settle then do it again, wile the pipes are off flush the systerm at same time.

Rex, are the matrix pipes both hot as they go through the bulkhead?
