1998 Dodge Grand Caravan 3.0 Highway Speed Overheating by gabhanjacisa
Jul 14, 2005 (5:59 am)
I live in SC, but my wife is taking care of her father's funeral in MI, so I am trying to diagnose this problem long distance. The radiator was recently replaced due to a crack in it, but some similar problems/symptoms are occuring. Sometimes (not all the time, but too many times to ignore), at highway speed (70+ MPH), with the a/c on, the temperature gauge slowly inches up past the normal range. It does not reach the point where the engine overheat dash signal comes on -- yet -- but it does go up too high and too freqently for my liking. The a/c will start blowing warmer air. (On the way up to MI, she was stuck on the highway for over 2 hours due to an accident, in hot weather, and at the beginning of this stand-still, w/the a/c on, the gauge started creeping up. She turned a/c off and gauge went back down to normal range for duration of stand-still.) My brother-in-law just yesterday replaced the upper radiator hose, saying there was a crack in it. My wife drove it immediately after that with no problems, however later when she drove it that day on the highway, the same problem occurred. Any help/suggestions would greatly be appreciated.

Trans Blow Up by mhipchen
Jul 14, 2005 (2:39 pm)
I have a 1999 Dodge Grand Caravan. While driving it one day not far from homeit jerked twice and the transmision blew up.Parts flew out of the bell housing on to the road. It did'nt have 40,000 miles yet.I know that the warranty ran out at 36,000 I contacted Chryslers help line. They wanted the original reciept, sounded fishy,I copied it at Kinkos and sent it off.Chrysler got back to me stating that there was nothing that they could do. I'd like to know if this happened to anyone else.What do I do now?

It sounds a lot like the other radiatior was blocked inside and that the system was not blown out properly. The debris could have circulated out of the old radiator and then be causing intermittent blockages in the new one. But if they did a good job flushing out the system before the replacement then this should not be the case.
 
Considering it still heats up on the highway, I guess you can nearly rule out a cooling fan problem.
 
Does it lose coolant at all?
 
You could check the thermostat for proper operation or just go ahead and replace it. Takes about 15 mins and is usually a cheap part. It could be failing intermittently and trapping coolant.
 
check back if you figure it out

AC Blowing warm air while stationary, cool air when moving by pete77
Jul 15, 2005 (8:55 am)
My '96 Grand Caravan is blowing warm air on the AC when the car is stopped in traffic. However, when we are moving - either city driving or on the freeway, the AC is blowing cool air.
 
Any suggestions on what is causing this and what can be done to fix it.
 
Thanks

Obviously you need someone to check that a/c out but here are some possibilities:
 
1) Low refrigerant charge.
 
2) Check the condensor. If the compressor stops at idle it is probably running hot and the safety switch shuts the compressor down. It may be obstructed.
 
3) Check the fan clutch to ensure proper operation. It may not be spinning fast enough at a stop to cool things off.
 
4) In a related check, make sure all fans are working properly. If they aren't then it won't be cool at a stop. Airflow at higher speeds helps to cool things down. You may just not have enough air going over the condensor.
 
give us a heads up if you find out what it is

power supply not working by cathc
Jul 15, 2005 (9:13 pm)
In my 98 Grand Caravan, both the front and rear 12V power supplies are not functioning. I checked the fuse chart, but there is no fuse listed for power supply. Everything else is working fine. Is there an easy way to fix this? Any help would be appreciated.

lastwraith: I flushed the system prior to the installation of the new radiator, so I don't think that is the problem but I will keep it in mind. I have told my wife just to go ahead and have someone put in a new thermostat for her since that is relatively cheap. Re: coolant loss, I don't know right now, because when it overheated the other day my brother-in-law decided it was a good idea to open the radiator cap with the engine hot, giving him a nice burn and causing the car to spray coolant. I'll have someone check on it in a few days.
 
I am curious if you know about the operation of the twin cooling fans on this car. When should they come on: all the time? With the a/c on? Only when car starts to operate above normal temp? And, are both of them to come on, or just one and then the other kicks in upon the occurrence of a certain event (a/c, above normal temp, etc.). I am wondering if, for some reason, only one fan is coming on when two should be on.
 
The interesting thing about this problem is that at speeds in excess of 70 mph for an extended period of time, the above normal temp will occur, but if you drop it down to 70 or lower, the temp goes back to normal range.
 
Thanks..

Power OUTLETS not working by cathc
Jul 16, 2005 (2:10 pm)
I used incorrect terminology in message 3025, "power supply not working" (it was late!). What I was (am) referring to are the power outlets. Thanks again for any help.

Of all the factory manuals I've ever used, the Chrysler-Dodge-Plymouth are the best in my opinion. They contain the most accurate and often other information that others do not. You will not have any trouble understanding them.
