steve g Posted January 24, 2013 Share Posted January 24, 2013 Recently changed my 300tdi 90 ('96) for a td5 ('04) and I'm surprised at how long it takes to warm up in this weather (around 0C). At least 10 mins before the needle get about 1/4 way up and pretty close to that before any even mildly warm air appears!Two questions really... Is this normal and whether it is or not, what can I do about it?? (... apart form put more clothes on!)ThanksSteve Quote Link to comment Share on other sites More sharing options...
ejparrott Posted January 24, 2013 Share Posted January 24, 2013 Rad muff, makes a hug difference to my 88. Without it the needle on my vdo gauge doesn't get off the stop(40) on the run to work, with it it'll get to around 60degC Quote Link to comment Share on other sites More sharing options...

V8 Freak Posted January 24, 2013 Share Posted January 24, 2013 Takes approx. 10 miles / 10 mins for mine to get to temp..... Quote Link to comment Share on other sites More sharing options...
ukspike Posted January 24, 2013 Share Posted January 24, 2013 03 Defender, mine was just the same as yours, I replaced the thermostat and it's nice and toastey in next to no time now, I would try changing the thermostat first, they are cheap enough.

steve g Posted January 24, 2013 Author Share Posted January 24, 2013 Thanks all. Sounds like thermostat 1st then muff. Steve Quote Link to comment Share on other sites More sharing options...

Off Road Toad Posted January 25, 2013 Share Posted January 25, 2013 Don't forget a new thermostat housing gasket either Not on a TD5! it's a self contained jam jar type affair. Quote Link to comment Share on other sites More sharing options...
Diablo Posted January 25, 2013 Share Posted January 25, 2013 Fair play. Assumed it was still the traditional sort, and the number of times I've had to make a gasket out of cereal boxes for things like this, when I've forgotten to order one Quote Link to comment Share on other sites More sharing options...
Guest Posted January 25, 2013 Share Posted January 25, 2013 I would say it sounds about right for a TD5 at this time of year, when doing motorway speeds I find it can drop quickly although the thermostats are not expensive <£20 IIRC I wouldn't bother changing it, it is at the bottom of the radiator so you will also have to change your coolant. I made my own radiator muff and it makes a massive difference, you just need to keep your eye on the temp just in case it does start to get too warm. http://imageshack.us/photo/my-images/266/wp000509u.jpg/'> [url=http://imageshack.us/a/img850/8264/wp000507.jpg[/img][/url] Jason.

Smego Posted January 25, 2013 Share Posted January 25, 2013 My 200 takes ages, probably 20mins, and temp goes down over 55mph Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted January 25, 2013 Share Posted January 25, 2013 My 200 takes ages, probably 20mins, and temp goes down over 55mph Need to change your thermostat then, mine is up to temperature in about 4 miles / 5 minutes on my drive to work. That's in lovely warm Scotland and with a viscous fan that's partially seized on! Quote Link to comment Share on other sites More sharing options...

rudilb Posted January 25, 2013 Share Posted January 25, 2013 (edited) Probably a 'standard feature' but my 2000 td5 heating system is erratic to say the least. Takes an age to warm up (that's expected) but once hot, it only pushes out warm air if the vehicle is moving fast (above 40 mph). I thought it could have been the speed of the water pump that made a difference (so for example, idling in traffic would not push the water around fast enough) but if I rev it hard at standstill it still won't produce any warmth. Heater fan works as poorly as it should and with direction on feet it still pumps out on the demisters. So no surprises there. It's almost as if there is not enough coolant (had that problem in previous cars) but the coolant level is fine. On motorway journeys it gets lovely and warm but around town I freeze! I've had this since buying the Landie 3 years ago so it's not a new problem... but in this weather i'm not enjoying it!

Off Road Toad Posted January 25, 2013 Share Posted January 25, 2013 Viscous fans normally fail in the 'on' position, check that as well as the thermostat Quote Link to comment Share on other sites More sharing options...
Tanuki Posted January 25, 2013 Share Posted January 25, 2013 TD5s are like that: they are efficient and waste very little heat into the coolant. Even when mine is fully warmed-up [like after a 50-mile fast run] if I have the heater going full-blast then in cold weather after five minutes of slow-city-traffic/engine-idling the temperature-gauge needle starts to drop. After ten minutes of idle it can be down into the blue gauge-segment. This is why Eberspachers and Webastos were invented! --Tanuki. "Thank you for calling the NHS Incontinence hotline.

western Posted January 25, 2013 Share Posted January 25, 2013 may need a new thoermostat if the heater temp isn't good enough & a adjusyement to the heater unit control cables http://forums.lr4x4.com/index.php?showtopic=33481&st=0&gopid=323899entry323899 Quote Link to comment Share on other sites More sharing options...

SteveG Posted January 25, 2013 Share Posted January 25, 2013 Jason - does the rad muff affect the intercooler? Would it be better to put a rad muff in between intercooler and radiator, or ones it not make that much difference? Cheers Steve Quote Link to comment Share on other sites More sharing options...
Guest Posted January 25, 2013 Share Posted January 25, 2013 Steve, I have not had an issue with the inter-cooler, the bottom 45 degree bit is not covered just the grill bit, so some air is still getting through. You can roll the front flap up a little if you need to let more air in. Jason. Quote Link to comment Share on other sites More sharing options...
