gazelle Posted January 3, 2008 Share Posted January 3, 2008 Now that it has become colder again I would like the grown ups to answer a question that has been bothering me for some time: If you want to warm up the truck quickly in winter, is it best to: - Keeps the engine working hard at low revs, or - Keep the engine working at high revs (once the oil has had a chance to get round!) - Drive anyway you like as it makes no difference. The TD5 in the deafener takes an absolute age to heat up and start de-icing the driver - thank god for the heated seats! Martin PS I know I could go the Webasto/Eberspatcher route but I cant spare the cash at present Quote Link to comment Share on other sites More sharing options...
GBMUD Posted January 3, 2008 Share Posted January 3, 2008 If you have a driveway, put a fan heater in the back of the car the night before and then, when you get up, turn it on. When you then go out (half hour?) later it will be toasty warm in the car and there will be no ice on the windows. If you are lucky the car heater will start to give off it's usual tiny amount of heat before the inside gets cold again. Chris Quote Link to comment Share on other sites More sharing options...
BogMonster Posted January 3, 2008 Share Posted January 3, 2008 The exhaust gas temperature on a Tdi is quite a lot higher when you are working it hard at low revs. I can't give you figures as it was installed in my 90 and I haven't got around to putting it in the 110 yet, but if you are doing X mph up a hill and the EGT is getting high, you just drop a gear and use more revs, and the EGT drops back quickly, which in turn would suggest to me that the engine will be putting less heat into the coolant. I guess this is why they say you should not labour an engine in the running in period. Quote Link to comment Share on other sites More sharing options...
Troddenmasses Posted January 3, 2008 Share Posted January 3, 2008 I would agree that using lower revs would heat up the components quicker - leading to very slightly more heat in the coolant. The question is whether you really want to be working the engine hard just when the lubricant is most viscous and therefore giving the least protection to the engine. I found that putting a cover over the front grille improved the heating no end on my series 3 (well, a piece of cardboard as I couldn't afford one of those nice Land Rover branded covers). Other than that, the best way to make yourself warm is to wear a thicker coat and some gloves As Chris suggested, a fan heater in the back is incredible. I used to live in the High Peak, and winters got a little chilly. I made an extention lead with a timer on the end, and plugged it into a fan heater every night. When it snowed, the heat from the fan heater even melted the snow on the roof - best of all it didn't mist up and was quite warm. Quote Link to comment Share on other sites More sharing options...
siearl Posted January 3, 2008 Share Posted January 3, 2008 I havent a clue what way to drive it but the 90 seems to warm up quite well without the need for anything. Quote Link to comment Share on other sites More sharing options...

I guess that there are other reasons in the cold to keep your revs down, like keeping traction/keeping torque down on ice etc. Quote Link to comment Share on other sites More sharing options...

FridgeFreezer Posted January 4, 2008 Share Posted January 4, 2008 For full on luxury buy a plug-in timer for it too so you don't have to remember to switch it on. Just remember to unplug it before driving off! Quote Link to comment Share on other sites More sharing options...

nas90 Posted January 4, 2008 Share Posted January 4, 2008 Burning that much fuel - I'm not surprised! Yes, LPG type fuel at 51.4 pence per litre and there are no particulates, like there is from God's own fuel Quote Link to comment Share on other sites More sharing options...
JST Posted January 4, 2008 Share Posted January 4, 2008 thats the sole reason i fitted a webasto to mine, i know irrelevant now to you. go for Chris suggestion. Quote Link to comment Share on other sites More sharing options...
ciderman Posted January 4, 2008 Share Posted January 4, 2008 Martin , I have a Kenlowe Hot start In the garage doing nothing , I took it off a 90 and it was working then , It simply taps into the heater hoses and has a plug that by the look of it takes a caravan type hook up and then into the mains . Failing that Ive found things warm up hell of alot quicker if you block the air flow to the radiator ,Mud usually works well Quote Link to comment Share on other sites More sharing options...
gazelle Posted January 5, 2008 Author Share Posted January 5, 2008 I like the fan heater idea a lot, but the truck is kept in a place to which I cannot run an electric cable with out p***ing off the neighbours. (guess how I know). Hence the need for other options. Gloves, a hat and a warm coat come time mind! Martin Quote Link to comment Share on other sites More sharing options...
