#23 of 72 Heater core replacement?? by muggelberg Jan 27, 2008 (9:12 am)
I believe my heater core has plugged up or is in new of being replaced. I have a 2001 caravan with only the front heat. how hard is it to replace the heater core in this model?? Any help would be great... Bill . . Replies to this message: shipo (Jan 27, 2008 9:18 am) muggelberg (Jan 27, 2008 9:33 am) shipo (Jan 27, 2008 9:44 am) and 1 more...

Replying to: muggelberg (Jan 27, 2008 9:12 am) Hmmm, what brings you to the conclusion that your heater core is plugged? I ask because I haven't heard of this being a problem, and I've been tracking this and other minivan boards for a number of years now.   Best Regards, Shipo Replies to this message: muggelberg (Jan 27, 2008 9:33 am) shipo (Jan 27, 2008 9:44 am) muggelberg (Jan 27, 2008 12:35 pm)

Replying to: shipo (Jan 27, 2008 9:18 am) My only reason for this is that I haven't seen any leaks and the vans not over heating(lack of coolent) The only thing it did do, is it threw a little heat for a second or too when I raced the engine a couple of times, but now there is nothing coming out but cold air.. I've let it idel for 30 mins and the coolent gauge shows that the van is plenty warm... just no heat what so ever soming out.. I'm was going to start with a rad and core flush(start cheap) and work towards the more $$$ things.. The local auto parts store has a core in stock, $90.00 and advised me that the dash would need to come out...yikes!!   Thanks for the reply also... Bill .

Replying to: muggelberg (Jan 27, 2008 9:33 am) I'd be inclined to suspect the blend door in the HVAC system before the heater core. I've never had to tear one of these apart and as such don't know what is involved, however, I have heard from some other folks that this task isn't too involved.   Best Regards, Shipo Replies to this message: muggelberg (Jan 27, 2008 12:35 pm)

Replying to: shipo (Jan 27, 2008 9:44 am) Well, I've figured it out.... Last night before I went bed I put extra coolent in the reserve. This morning on the way to my buddys oil change shop to flush the Rad, the heat came back...Hummm that's odd I thought.. I was going to turn around and head home( figuring out that it was fixed) but I stopped by his shop... He and I began to flush the rad anyway, and what do I see??? coolent flowing from the bottom of the motor!!!!! The water pump did go bellyup.. and I had NO coolent in the engine(therefor no heat) So, it's in my other buddy shop to the tune of about $400 with parts and labor ... Thanks everyone for the input....   Bill. . .

Replying to: pinmed (Feb 28, 2008 4:06 pm) This is a very common problem, all you need (typically) is a blower motor resistor ($17.69 from NAPA).   http://www.napaonline.com/MasterPages/NOLMaster.aspx?PageId=470&LineCode=ECH&Par- - tNumber=BR266&Description=Blower+Motor+Resistor   Best Regards, Shipo
#30 of 72 Re: Can't check AC compressor for 1998 Plym Voy. by gg1328 May 11, 2008 (6:36 pm)
I purchased a 1998 Plymouth Voyager Expresso 3.3 engine last week. I also purchased the Hayes Repair manual. It states in order to put R-134 in, the compressor has to be running. If not, jump the LOW PRESSURE CYCLING SWITCH with a jumper. It does not show a picture of what it looks like, nor where it is located. Can any body please clue me in on the exact location and what it looks like? Thanks in advance. Replies to this message: ccdlpd (May 27, 2008 8:59 am)
#31 of 72 Fan belt squeals by nclake1 May 16, 2008 (4:39 am)
98 Caravan: Replaced serpentine belt at about 100,000. Belt squealed when A/C is turned on and intermittently at highway speeds with A/C on. Had belt tightened, temporary relief. Belt began to squeal again when A/C turned on and intermittently at highway speeds with A/C on. Did not squeal with A/C off. Replaced belt. Temporary relief, but squealing began shortly again. Have had this problem for 50,000 miles and mechanic does not seem to be able to figure it out.   Now the belt squeals when ever the A/C or the heater fan is turned on and squeals intermittently at highway speeds with either A/C or heater fan on.   I love my mini van, but I am afraid the belt will break in some desolate place or worse. Any suggestion would be greatly appreciated. Thanks Replies to this message: shipo (May 16, 2008 5:14 am) nclake1 (May 16, 2008 2:47 pm) shipo (May 16, 2008 4:34 pm)

Replying to: nclake1 (May 16, 2008 4:39 am) Had belt tightened, temporary relief. Ummm, these vans have a spring loaded "belt tensioner", so unless you had your mechanic replace the tensioner with a unit that has a higher tension, then there is no such a thing as "tightening" the belt.   Over the years I've read about many belt issues on these vans and squealing is almost always one (or more) of three different issues:   1) Cheap belt. I've personally had to deal with this one, I was too lazy to replace my own belt a couple of years ago and so when it was in for the annual state inspection, I had the shop put a new belt on. Needless to say, they bought the cheapest belt they could find. Damn thing squealed from Day 1. I finally got tired of the squealing and bought the best NAPA belt sold and put it on, squealing gone and has remained gone for the last 20,000 miles.   2) Oil, Power Steering Fluid, or Coolant contamination: As engines and accessories, age they tend to leak, fact of life. Check to see if there is any contamination on the belt surfaces.   3) Failing or failed A/C clutch or compressor. Of the two I'm thinking that the compressor is most likely. Do you hear any noise or racket emanating from the compressor when the A/C is working?   Best Regards, Shipo   Edit: It just occured to me that you might have a 4-Cylinder engine or the Mitsubishi 3.0 liter V6, all of my comments were made assuming you have either a 3.3 or a 3.8 liter Chrysler engine. If you have either of the two smaller mills, disregard my comments. Replies to this message: nclake1 (May 16, 2008 2:47 pm) shipo (May 16, 2008 4:34 pm)
