FREELANDER Pre-Heater

Nov 21, 2004 7 Replies

Have just had an answer to a previous question regarding noises which materialise as Pre-Heater noises on my TD4 LS Freelander. How does this Pre-Heater work. Many thanks for the original answer to Paula but I was unaware that I had a Pre-heater! (things have moved on since my series 1!) I used to have a pre-heater on an old VW but that had dials & switches on the dash. I can find no reference to it in my booklet.


being a diesel engine it will have something to pre-heat the combustion chamber area as compressed diesel likes to be warm when it goes pop and the preheater warms things up a bit.

I am not familiar with the newer land rover engines but I expect it's mostly automatic and it also stays on for a few minutes after the engine has started.

someone who knows what they are talking about will be along presently..........

NOOOOO

The TD4 is a remarkably efficient engine which does mean that is struggles to get to operating temperature in low load situations. (more efficient means less wasted energy ie: heat)

So In order to maintain a correct running temperature (probably more to stop people from moaning about the lack of heater than for engine life) there is a diesel fired heater fitted to heat up the coolant !!!!!!! while the engine is running.

I dread to think what the tree huggers would think about that. The Super efficient low emission engine being kept warm by another oil burner!

I do think there was / is an option available to switch this on via a timer etc. to act as a true block heater for cold climates

I didn't know that, does the TD5 and TD6 have one too?

As far as I know it's not a standard or optional factory-fit item on the Td5, but the Td6 has one as standard. They are an option on the V8 Range Rover.

To Paula, thanks you are a star! The year of manufacture is 14.11.2000 and warranty has expired. Has just been for its 96.000mls service with no problems. To Neils question, I am unaware of a centrifugal oil pump.

Go have a look at

and you will find the heater fitted to the Diesel Freelander. It can be upgraded to remote control, timer control, and even mobile phone control. I have one on my Defender with remote control and timer.

I remember looking long and hard for it in mine. I think it's called a "positive temperature coeffecient ceramic diesel heater" or soemthing.
