Hello all. My wife and I are considering purchasing a 04 H2. We test drove it last night and she really liked it. I am not new to 4X4's but they have been mostly Toyota's and older Chevy's. Could someone tell me what I should be looking out for? This one has 104XXX miles, sits on 37" Dick Cepek tires and has a check engine light on. I pulled the code and it is P0118, engine coolant temprature circuit high. Is that just a sensor failure or something more menacing? We currently have two 5th Gen Camaros that are cammed and modded. I can do a lot of the work myself if needed but dont want to buy a money pit. I was reading the forum last night while waiting to get posting authority and have lots of questions about options. It appears to have center and rear locking diffs but I dont know how to tell if it has air suspension. I didn't crawl under it to look. I also read to check the power steering as it may be leaking since it has the larger than stock tires. I'll have to look if we decide to pursue it. Also what about the roof leaking? Dont know if this one does as I only sat in the back while she drove. If it does, does that mean its a no go? I did notice that the AC was dripping a lot of water. I did the feel/taste check to make sure it was water and not antifreeze or oil. Anyway, I'm rambling but if y'all could answer those questions it would get me started. Thx.
