You are in the Pontiac Montana
What is this discussion about?
Pontiac Trans Sport, Pontiac Montana, Van
Apr 05, 2008 (12:11 pm)
I have a 1998 Pontiac Trans Sport. Recently I have noticed that everytime I come and go I smell coolant, I thought there was coolant possibly blowing out of the hose when I am driving. I see that there is a small puddle of coolant on the top of what I believe to be the thermastat. I am having to add coolant about every other day at this point. I thought maybe it was just the hose but now I am thinking its the water pump. I have not had any problems with it overheating at all. My mechanic quoted me $150.00 to replace it but I do not have the money. I did get a new water pump and hose but am at a loss not knowing if its actually the water pump or not. The upper and lower manifold gaskets have all been replaced a while back along with a new radiator. I do not use Dexi-Cool due to having that be the primary reason why the upper and lower manifold gaskets needing replaced. I am seeing no anti-freeze on the garage floor. Your input would be greatly appreciated. Here is a link to some pics of what I see. http://s297.photobucket.com/albums/mm213/1998_TransSport/">
#1328 of 1493 Pontiac Montana air leveling system
Apr 22, 2008 (3:18 pm)
I have a 2005 Pontiac Montana with the rear air leveling system. The problem is that the compressor pumps the shocks all the way up and does not release any air . I have replaced the complete air compressor and all the parts on it, the switch and control arm on the axle and a relay on the side of the compressor. Replacing all these parts has not helped one bit. Any ideas or suggestions would be a great help.

Wondering if you are still on the forum and if you ever found out the problem with your leveling system ? I have a 2005 with the same problem.

I had the same problem, ended up being a faulty transmission pressure sensor. I replaced it and now it shifts like a champ. Now, about 15k miles later, I am getting a weird rumbling noise from the drivers side of the engine bay. Sounds like a Civic with a fart can muffler under my hood. I took it to Les Schwab and they checked the brakes and bearings and said they were okay. I can't pin the noise, and if I turn to the left while accelerating from a stop, the traction control kicks in. Any ideas?

Yes, be careful I had to take my son to the emergency room, the door closed on his hand and fractured 3 bones. I've spoken with the GM reps and they said there is no plan on a recall to fix this problem. After having numerous problems with this van, the same model and year I owned previously, a grand prix, and a camaro, I am seriously contemplating changing manufacturer loyalty.

Are you speaking of the auto slider door? I started having problems with the slider on my van not wanting to close or getting stuck in the open and close mode (1998 TransSport) and just keep the switch on the off position. Did take it in for the recall but the dealer at the time did not have the parts. I will never own another pontiac. I originally purchased this van (New, Not used) anticipating on having a wheelchair lift put in a couple years later to aid in transporting my son that is severely disabled and when I went to do so I was told that the year I have would not accomidate the lift that I wanted and that they would have to cut and raise the top (NOT!!!) The slider doors on each side of the 1998s is narrower then the year before and year after. My son is now almost 21 and I am still the lift system. I paid this vehicle off within the first year and could not afford to get another. The guys at the dealer basically lied saying that this vehicle would accomidate the lift system when I bought it.
#1333 of 1493 2004 temp problems
May 09, 2008 (5:36 pm)
I just got a used 2004 Montana, love it so far but have noticed the fluctuation on the temp gauge. Hwy driving has been fine, one tick below the half way mark, but stopped at the drive thru window at the bank on a warm day and noticed the temp gauge going higher then halfway, maybe on tick below the 3/4 mark. Once I started going it got back down and then reached my destination. Once I started going home it started reaching the 3/4 mark again (stop and go) once I was back to hwy driving it lowered to the one tick below the halfway mark. I have noticed lately it has been ok for the most part but when I drive slower (trying to find a location) and stop, turn around etc it starts going above the halfway mark. Anyway reading the forum I have seen the gasket problems, but didn't see many for the 2004, is this issue with this year as well? Haven't seen the coolant light come on or anything, but I have never had a vehicle have this much fluctuation in the temp before. My hubby was wondering once you change the gasket will it be fine or will this continue to happen over and over. Thank God he can do it, so we won't have to pay for the labor, just parts.

Hi, I may be able to help you a little! I used to sell cars for GM. I had a situation like
yours with wanting to add a wheelchair lift! Now I have sold cars for a long time, so believe it or not, your not the only one with this problem!!! Your 1998 will support a wheelchair lift. You just have to find someone to do it! The dealership wont do it cause it would void the warranty! Do you still even own the van? If so the warranty may be dead anyway. There will be no top cutting as well. Ive seen it done! Plan on spending around three grand! I hope this info helps!

i had the same problem in my 1999 montana, the problem with the gaskets is that they are made of plastic and they develop cracks. i did not find out until it blow out a head gasket. $1700 dollars later the car is running ok.

The original gaskets in the 3400 engine are bad. The coolant, after a few years, eats away at them. After changing the gaskets you must do a coolant flush and change and say good bye to Dexcool. Check your antifreeze level and I would bet it is down and your engine oil level is up!
