I have a 2006 Jeep Liberty CRD and just moved to RI this Fall in time for the cold weather. How long should I leave the key in the pre-start position before starting on really cold days (it was in the mid 20s when I left for work this morning)? I know the owners manual says to leave it until the Glow Plug Indicator light goes out but mine doesn't illuminate and I am afraid that it is burned out. I'm driving up to Toronto and Buffalo this weekend and love my jeep. Is there a good rule of thumb; ie. 1 additional minute for every 10degrees below 40 that I can use?

I had wanted to get on the road first thing in the morning but am wondering now if it is better to stop somewhere and make sure the glow plug system is working properly. Any recommendations for the New England Area?

Thanks in advance.

Do you have the block heater? if you don't have a visable plug to plug the jeep in with an extension cord to warm it up on cold days, get a flashlight and there should be a black plug/wire wrapped up and zip tied to the oil dipstick. Most of the crd's came with it from what i read. Mine was zip tied and i just routed it through the grill and plug it in for a few minutes in the morning when its cold.

Im also in RI.

I received and used my new Overland Diesel 2014 in november. 5000km to date
I had to start in cold weather in Québec La Malbaie. -26 celcius or -15 Fahenheit. It stated whitout any hezitation. Howerer, it is not a good habit, I prefer plug it when we could have electricity for the parking site. Up to date very satisfied. 10 liters per 100 km (23,5 mile/gal(us)) in very cold temperature mix city and highway. Could not be more happy. My GMC 4.8 liter (292 cu in) made 13 mile/gal (us) in the same condition and temperature. average of -10 F

In two week, I am going for a road trip to Quebec California 16 000 miles trip towing a 19 foot trailer 4300 pound (dry 2900+ 400 option+ 1000 equipement) with all camping gear and acc. I will keep you inform: my GMC did 12 mile/us gal for a trip to miami.

My 2005 Glow Light Plug is generally very quick to go out. In the cold weather (single digits above 0 F) it was going out after about 5 seconds. I would think that 1 minute would be more than plenty.

That is also my problem with the wife's Liberty. Any idea or recommendation which aftermarket brand that would last longer compared with oem plugs?

I was taught a tip by my son-in-law, who has diesel VW's, he says make sure it is plugged in, make sure you are adding diesel conditioner and DOUBLE PLUG IT. This means, wait until the glowplug light goes out, turn the key off and then on again right away and start it when the light goes out again.
