#1424 of 1454 Disconnecting transmission cooler lines by aitkenhead Jul 26, 2009 (7:14 pm)
I want to install an auxiliary transmission oil cooler in my 03 Montana. I do not understand how to disconnect the existing rigid cooler line at the radiator. Hayden/Imperial, manufacturer of my new cooler, had me order their fit kit number 397 which is just a flared brass tube, a compromise coupling. I am supposed to release the existing rigid tube at its quick-disconnect union at the radiator and substitute their coupling. I've tried several quick disconnect tools from the auto parts store, either split nylon collets or scissors-like tools that are supposed to encircle the rigid tube and slip into the union to spread the spring clip in there. These don't work for me (admittedly, they don't claim to work on transmission cooler lines). Any DIYers out there solve this one, or is there a professional who can give me a hint?

#1426 of 1454 Re: overheated 1997 pontiac montana trans sport [quehouse] by nthompson1 Jul 29, 2009 (3:29 am)
Replying to: quehouse (Jun 13, 2009 5:24 pm) Reply to quehouse reply. Have had a new radiator/radiator cap installed. Overheating probem is sooner, worse. The mechanuc who installed the radiator in 2 hours, gunned the engine for about 45 minutes(on and off, mostly on). This frightened me. After I left and went to Walmart, it overheated 30 mintues later. I took the Trans Sport back to mechanic. He released the pressure with a tool, and spent about 5 minutes on vehicle. He said all it needed is to be burped to get air bubble out. Driving home, it still overheated. I stopped at another service station and asked him to burp it. Mechanic there said head gasket is blown. I have tried all kinds of ways to burp the radiator(cap on and off, adding coolant, etc.) in the driveway. After first mechanic replaced cracked end radiator, vehicle now sends out white smoke, and oil is showing higher on dipstick. How do I know if the problem is intake manifold gasket or had gasket? Please help me. Replies to this message: boga228 (Jul 29, 2009 6:05 pm) quehouse (Jul 30, 2009 9:25 am) spike99 (Aug 02, 2009 8:43 am)

Replying to: nthompson1 (Jul 29, 2009 3:29 am) No matter what the problem is they still would to pull the intake out to check the gaskets. They also can do a cylinder leakage test or a compression test on the cylinders. Try and find a good mechanic if not see the dealer to find the real problem hope that helps.

Replying to: nthompson1 (Jul 29, 2009 3:29 am) I am almost sure that what you describe is a intake manifold gasket problem. What kind of mechanic installed your rad and did not notice that your engine oil was way over filled?? I would be looking for a new mechanic if I was you.

Replying to: nthompson1 (Jul 29, 2009 3:29 am) Sometimes, an engine can have a head and/or intake gasket leak and NOT show any external signs. For example, the "leakage" is being sucked into the cylinder very slowly and its very hard to detect. Even from inspecting its spark plug color and tail pipe color. If the RAD system constantly needs burping, then air is getting into its system. Most likely from blown head gasket.   After engine is cool (sitting 24+ hours), remove its rad cap, let engine idle and "warm up" on its own (say 10-15 minutes), then look down its rad cap opening. If you see a bubble of air floating to the top, then its most likely a blown head gasket. That's how they detected blow head gasket on my previous vehicle.   Being a 12+ year old van, I'd seriously think about trading in or selling for parts. Replacing head and intake gasket (do both at the same time) can cost from $2K to $3K. Especially if heads need to be plained down (to remove warp) as well. If wondering, I had to "dump" a previous GM vehicle that had a head gasket leak. It wasn't worth fixing either.   Hope this helps....

#1431 of 1454 HELP please by luvmyvan2 Aug 09, 2009 (8:54 am)
hello all i own a 2002 montana and last night had the scare of my life. it was raining and i had my youngest and my 4 month old grand daughter with me.   i wasn't too far from home thankfully, when the heat gauge went way up and the temp light came on, i had no power in the motor ( barely made it up the hill ). pulled over to the side of the road and threw on my hazards. (dangerous spot to have to stop but had no choice).   lots of coolant in the resevour, let it cool down for about an hour, drove it back home and parked it. this morning i started it back up to see if i could find a problem now my oil light is on and the oil life says it is at 0. just had the oil changed last month at the dealer.   has anyone else had this sort of problem and could you please tell how to fix it? this is my only vehicle and i use it daily as i am moving.   thank you for reading my post Replies to this message: spike99 (Aug 14, 2009 6:45 pm) luvmyvan2 (Aug 15, 2009 6:03 pm) kkollwitz (Aug 16, 2009 6:53 am)
#1432 of 1454 2004 Montana hatch door by quakergil Aug 13, 2009 (6:38 am)
I need to replace the back door or have it fixed. My ? is,What previous years have the same body parts. So, will a hatch door off of a 99', 00'or 01'models be the same hatch door as the 2004 model. Or even the Transports models, might they fit?
#1433 of 1454 Re: HELP please [luvmyvan2] by spike99 Aug 14, 2009 (6:45 pm)
Replying to: luvmyvan2 (Aug 09, 2009 8:54 am) Immediate engine over heating could be from a variety of different reasons. Anything from "stuck / broken" inner engine oil pump, to too low of engine oil, to plugged oil filter (assuming the previous engine oil replacement folks did change the oil filter), to plugged up main radiator, to stuck main rad `thermostate`, to electric main rad fans NOT turning on when they should, to even engine head gasket leakage. Variety of different reasons that a certified auto mechanic must investigate. As a suggestion, call a few local auto mechanics in your area and ask them to investigate. Can you drive your van to your local mechanic or get them to Tow Truck it to their shop? Hard call on this decision. Hopefully, its a simple stuck thermotate or perhaps a broken wire on their main rad's electric fans. Hopefully, its something this simple (and low cost) to fix.   Good luck.
