don't mean to hijack your thread but this just came up
I just noticed a coolant leak yesterday afternoon on mine I had been sitting in pa for 2 days with truck off. yesterday I went into restroom and when I came out I noticed coolant on the ground. so I checked the over flow it was full "were it is always at cold" got on the ground in the snow and saw coolant on the radiator support took it to a shop 3 miles down the road they said it was that my lower radiator hose clamp had come lose by a turn or too. I thought this was odd because ain't no one been under there since the middle of november. They said when it gets this cold out the plastic contracts at the hose fitting so I will see a coolant drip sometimes. never seen it before on anyother truck or van I have owned they said they tightened it up and I drove 900+ miles today and I have been sitting here now for 2 hours with van off and no drip yet. anyone else ever heard or seen this before. I thank they called it a cold air leak or something on the order of that:confused:
