mr_mcp Posted November 19, 2009 Share Posted November 19, 2009 Has anyone changed their heater matrix with good results? The heater in my Defender is puffing out lukewarm air and I want a fix before it starts getting really cold!! Cheers, Mr_mcp Quote Link to comment Share on other sites More sharing options...

Cheers, Mr_mcp Ralph has a post on here for adjusting the heater controls to make sure they are working properly. Have a search - possibly in the tech archive. Worth doing before changing things. Maybe backflush the matrix before changing it as well. Quote Link to comment Share on other sites More sharing options...
outdoor_ian Posted November 19, 2009 Share Posted November 19, 2009 Guessing you have seen the one currently on flea bay Quote Link to comment Share on other sites More sharing options...
mr_mcp Posted November 19, 2009 Author Share Posted November 19, 2009 Thanks for the quick responses, I tried the search but didn’t find any useful posts (probably more poor search criteria). Yeah the one on eBay looks nice and shiny – didn’t know you could get uprated ones. Although to be honest I just want a relatively cheap fix <£40 and that looks like it'll go for a bit more with the rrp being '£200'. Has anyone bought one from paddocks, they seem fairly reasonable?

If so, don't expect lavish walls of red hot air, particularly on older series machines and 90 / 110 / early Defender (LR may have sorted it, but has been a joke for plenty long enough). 1) Have you followed Western's guide to heater control adjustment in the tech. archive? 1a) If not, have a read and then move on. 2) Have you checked to see if the thermostat is the right one (there is an optional cooler one for many engines, for use in very hot (hah) countries), and in fact actually fitted (they get removed to "fix" overheating problems) as no 'stat pretty much equals no heater in most Landys. Later engines don't generate masses of surplus heat anyway! 3) Otherwise, if the vehicle is quite old and likely to be on its orignal matrix, then get a new one, as it's probably furred up inside.

Yeah first winter in the landy! I was expecting it to be cold, but after an hours drive on the motorway I was expecting the heater to be warmer than my breath! I'll take a look at that article, thanks! Quote Link to comment Share on other sites More sharing options...

It should get above blood temperature (albeit just) ... I'd try the cheap things first! That brought on a nostalgia moment - -10 © outside, me sat in 109 with series Smith's heater going, only -5 © inside ... ah, happy days!

poohbear Posted November 19, 2009 Share Posted November 19, 2009 Not meaning to rub anybodies nose in it - but my heater gets ruddy hot once the engine is warm. Usually at a decent 'cosy' temperature within ten minutes of driving. D. Quote Link to comment Share on other sites More sharing options...
outdoor_ian Posted November 19, 2009 Share Posted November 19, 2009 yeah scrapping frost off the inside of the window is always interesting first thing in the morning!!!! Quote Link to comment Share on other sites More sharing options...
Ex Member Posted November 19, 2009 Share Posted November 19, 2009 The heater should put out lots of hot air when adjusted properly and in good nick. As mentioned, the first and most important things to check. 1) Thermostat is not leaking when closed. The engine temperature should come up quickly to the normal temperature and you should see a dip when the thermostat opens. 2) Move the hot/cold flap to hot and make sure it is pressing tight against the stops. If not, pop the cable clip off and adjust. Quote Link to comment Share on other sites More sharing options...
lrfarmer Posted November 19, 2009 Share Posted November 19, 2009 heat whats that my 90's heater works but the motor dosn't you get a small bit of cleared screen on the pasangers side one day i'll find the time to fix it Quote Link to comment Share on other sites More sharing options...
V8 Freak Posted November 19, 2009 Share Posted November 19, 2009 As someone said above, check thermostat, check the heater flap settings , make sure some hot water is going through the heater matrix etc. Are the radiator hoses hot? My 87 heater was getting hot but it was so furred / blocked up it wasn't effective. Changed it and blistering difference. Neil (it does also help having a V8 with a lorra excess heat available!)
