#22 of 51 Re: Radiator replacement?? [xwesx] by hdbrg1 Jul 25, 2007 (4:30 am)
Replying to: xwesx (Jul 24, 2007 1:40 pm) My gauge normally ran between 1/4 and a 1/2. I noticed a couple weeks ago that it was running at half way, and a problem I do believe I have. Not sure how far I can drive safely. I live in Germany and there's not a whole lot of Chrysler dealers around. And if I drive to Italy or France I'm really hurting if it breaks down. Guess it's time for a new van. Replies to this message: xwesx (Jul 25, 2007 9:18 am)

Replying to: hdbrg1 (Jul 25, 2007 4:30 am) Well, start with flushing the radiator with a good solvent to clear any blockages and see where that gets you. If the van is running too warm, you would probably notice some significant variations (drop) in the temperature gauge when you are running at high speed and low rpm (such as descending a long hill).   The bottom line, though, is that if you cannot feel at ease when driving it and do not want to fix it, then it is likely time to move on to something else.

Replying to: tatalesua (Jul 23, 2007 10:59 am) Does it over heat in cooler temps.?    1) Check the fuses for the cooling fans.    2) When you see the temperature gauge going up to hot. Pull over, open the hood and see if the cooling fan is going. (If not, it might be the coolant temp. sensor.)    3) With the van running in Park, at idle speed, turn on the AC and see if the cooling fans are running. (Both fans should run all the time when using the AC.)    4) Make sure there is nothing blocking the flow of air through the cooling coils in the radiator. Sometimes you might have to run the garden hose over the cooling coils to rinse away all dirt and lent build up.    5) You can check the top radiator hose when the van is cold, to see if the thermostat is opening up and not stock closed. When you first start the van, let it run in Park at idle. As you see the temp. gauge going up, feel the top radiator hose to see if it is getting warm/hot. If it is still cold, then the thermostat has not opened yet to allow the coolant to flow thru the radiator to be cooled. If you see the temp. gauge going past the halfway point and the top hose is still on the cool side, it might be the thermostat

Replying to: singlemom3 (Apr 27, 2007 11:26 am) Hi,      You may have a short in the primary power wire from the relay to the cooling fan motor. A multi-tester in the continuity setting would confirm if theres a break in the line. An akward visual inspection from underneath the vehicle may also spot it. If so,cut the bad piece out and splice in an equal gauge of wire to graft it in to position. Ideally, copper wire could be soldered with rubber heat shrink tubing placed around it to seal it.
#28 of 51 Blower issues fixed by muggelberg Aug 09, 2007 (6:12 pm)
Thanks everyone, I ended up replacing the resistor pack myself (very easy). I think it cost me $18 and some change. I ended up having to cut off a small piece of wire to the blower motor(melted) and replace the end with a female connector from autozone for about $6 dollars.   All in all I think the whole thing was about $24 and tax.   And to think, the dealer said it was going to cost me $80 to LOOK AT IT!!!!   Thanks Bill
#29 of 51 98 Voyager overheated white smoke comes out by eric2 Sep 06, 2007 (1:28 pm)
my 98 voyager overheated again today, it has an overheated problem about 1 month ago, I replaced the fan relay, then it seems running good until today. When I stopped my car in the parking space, I heard a noise coming from the front, sounds like something boiling water. I guess it was the coolant, but when I look at the temp guage, the temp was right at the middle, seems normal to me, but next second, lots of white smoke come out under the hood, but no burnt smell, and the coolant spill over over the floor.....smoke stops about after 10 mintues. what should I do next?? please advice.

Replying to: eric2 (Sep 06, 2007 1:28 pm) What you saw was apparently steam and not smoke, a very important (and fortunate for you) distinction. It sounds like you need to fill the radiator and coolant overflow bottle and get it to a decent mechanic to debug the problem.   Best Regards, Shipo
#31 of 51 radiator cooling fan relay location by jrcaracci Mar 20, 2008 (4:21 pm)
The radiator fan keeps running on my 2001 Chrysler Town and Country, even with the ignition off. Also got engine light signal. Switched 40A relay in fuse box and this did not change situation. I believe the fan motor control relay is stuck in the closed position. Problem is I can't find where this relay is located on the car. Checked Chilton and Haynes manuals without success. Can't find anything on-line pertaining to location. Both Murray's and Autozone have replacement part but were no help in locating where to find it on the van. Dealers are all down for the weekend.   Does anyone know where this relay is located. Replies to this message: pmary (Jun 06, 2009 7:52 pm) schampio (Jul 16, 2009 1:40 pm)
