aerocorey Posted January 29, 2009 Share Posted January 29, 2009 What's the difference between a heater core with horizontal pipes and one with vertical pipes other than the orientation of the pipes? Quote Link to comment Share on other sites More sharing options...

Ex Member Posted January 29, 2009 Share Posted January 29, 2009 Umm, no... The cores are different sizes. Quote Link to comment Share on other sites More sharing options...
JonR Posted January 29, 2009 Share Posted January 29, 2009 The horizontal pipe matrix is aluminum, as opposed to brass (or was it copper?) on the other type, which, on mine anyway provides a faster warm up in comparison. Jon. Quote Link to comment Share on other sites More sharing options...
Simon B Posted January 30, 2009 Share Posted January 30, 2009 Was reading the Bearmach catalogue (got bored with the Bravissimo one) saw a "high efficiency" heater matrix but the text said it was only 20% better but for a fair bit of cash more.

Dr Goon Posted February 1, 2009 Share Posted February 1, 2009 I think I need to replace the heater matrix on my 110. It is barely putting out any heat at all, even at 65mph on the motorway. I suspect that the matrix is full of mud and so very little air is passing over it. The fan works OK at all 3 speeds and the engine temperature is nor abnormally low. I do not have any sort of fan on the vehicle following removal of a knackered viscous unit about 2 years ago. I have spent ages on the 'net tonight trying to work out which is the correct matrix for my vehicle. My 110 is a 1996 export model with aircon, the early type which means I have no bulkhead fresh air vents as the dash panel is full width. The controls are not the normal ones each side of the instrument binnacle but mounted on a panel in the centre of the dash. There are 3 buttons that control air distribution, one each for screen/facia/footwells. A horizontal slider for temperature control (ha ha!) and a vertical four position switch for fan speed: off - 1 - 2 - 3. The facia can be seen in some of the pictures in the following thread http://forums.lr4x4.com/index.php?showtopic=11057 When the facia vents are open, those on the nearside blow vaguely warm air, the ones in the middle vaguely tepid air and the one on the right, cold air. I have read all the threads about improving defender heater performance and I ahve reached the conclusion that the matrix has probably had it. Can anyone help as to which matrix I need: two are listed, one with horizontal pipes and the other with pipes that curve downwards. I cannot find any information as to which is likely to be the correct one for my vehicle. Many thanks. Quote Link to comment Share on other sites More sharing options...
western Posted February 1, 2009 Share Posted February 1, 2009 300Tdi needs UTP1725 for vehicles with air cond for upto chassis number WA159806 Quote Link to comment Share on other sites More sharing options...
Dr Goon Posted February 1, 2009 Share Posted February 1, 2009 Thanks Ralph. At least I can now look at getting one ordered and then talking to my friendly mechanic to get him to try and fit it. I assume that the fitting is not complicated by the fact that I have got air con? Quote Link to comment Share on other sites More sharing options...
western Posted February 1, 2009 Share Posted February 1, 2009 heater box is in the engine bay same as any other 90/110, so that will need removing to swap the matrix, I'm sure your tame mechanic can handle it the air con kit shouldn't make it any more difficult.
