I have one of these vans and it is closing in on 100,000 miles - my low coolant light came on a couple of days ago and I added a quart of dexcool and it has not reappeared so far - I looked under the very cramped engine compartement and felt around the hoses that I could access to see if I could find a leak but there is nothing obvious - note that I did have the intake manifold gasket replaced at 70,000 miles about a year and a half ago at a GM dealer - I am just wondering if the the problem is coming back - can the leak be seen or felt on any part of the engine from under the hood or is it mainly an internal leak? One of my main worries with this situation is that damage has gradually been done to the engine because this problem has probably existed for some time. Anyway I will probably be taking the van back to the dealer where I got it repaired the first time but just want to confirm that this is the problem if possible before I do that
Thanks for any assistance or advice
