| Post subject: | CRD will not heat up!! |
Not so much the engine, but I want to run this by someone and see if it's normal. I get up in the morning and since I live in NL, Canada it's pretty cold at 7:45 AM. I start up the Jeep and leave it running for 15-20 minutes and have the heat turned on. I come out to leave and it's still freezing inside and the engine temp gauge is still reading the very bottom. It's not until I'm driving for 10 minutes that the temp needle is pointing 90 degrees up and stays there...it's then that the temp inside the vehicle finally goes up. Then, for example, if I'm sitting outside of a mall waiting for my wife with the vehicle still running, the temp will start to go back down and the air coming from the vents actually turns to cool air again. If I turn it up on 3-4 the air is actually quite cool even if it's turned on the hottest setting and the vehicle has been on for 40 minutes to an hour. Is this normal!?!?!?! It doesn't seem like it should be!! |

Are you on one of the mix settings with really cold outside air? Mine - at 25-30F (coldest it gets around here) doesn't warm too well at idle but it's blowing warm air on the recirc within a mile and will heat the outside air to hot within 2 - and by that time the temp needle's centered straight up. It doesn't cool off while the engine's on. the CRD does have a seperate viscous heater to warm things up since the standalone diesel doesn't warm up quickly. Yours sounds like it's not working. |

It has a little graphical guide... should be easy to find. It could just be that cold up there. My temp gauge fell today... it was about 20ºF. |

my CRD heats up VERY quickly when driving, when I stop and idle the temp and heat output drops considerbly after 5-10 mins or so. Even here in Georgia on a cold morning (OK not really cold but just above freezing) if I start the CRD and let her idle she doesn't really warm up or heat the cabin. I'm pretty sure if I went home to me mothers in Moretons Harbour, Newfoundland with my CRD where it can get truly cold that I could idle her for an hour and she wouldn't be very warm at all. |

My experience with two VW TDI's is that they will not warm up just ideling. They have to be driven for 3 miles to get good heat:!: Heat comes from a inefficient engine and our diesels are very efficient  The TDI's will actually cool off after they are warmed up sitting at a traffic light  My CRD starts to put out a little heat in about 2 miles

Our CRD makes heat in less than a mile, even if its 15 degrees out, and it will continue to make heat even at an idle. I would say that the viscous heater is not kicking on. You should be able to tell, it will draw the engine down right after you start it on a cold morning...much like the AC compressor kicking on. |

I have always noticed the same thing. When driving i have lots of heat, but to just start it and let it sit no heat. My viscous heater works i can hear it but no heat. I just figued it was a diesel thing. I remember having a high idle installed on a 98 gm so that it would heat up. I have an interior car heater in the jeep si it keeps it not so cold till the engine heats after driving. even at -30 C only takes 2-3 km till i have heat. |

It's is not uncommon for it to take 10 to 15 minutes for mine to warm up when it's cold outside. When I say cold I mean like -10 to -20. When it's nice out, like +30 to +40 it heats up in the first mile or so but there is a huge difference between +30 and -20. Have you tried your block heat at nights? that should help alot. |

Yep, mine takes a long time to heat up to in this weather (<-15C) . Once heated the guage sits at 12o'clock but as soon as I stop at lights the temperature drops rapidly! |
