Replying to: johnson11978 (Mar 24, 2008 8:27 pm) I'd check the weep hole on the nose of your water pump. While the pump on our 2003 is still intact and not leaking after well over 170,000 kms, I've heard from other 2003 owners that their pumps started leaking right around the 100,000 km mark.   Best Regards, Shipo
#34 of 51 I think I found the leak, now what? by mosander1 Apr 14, 2008 (10:56 am)
I have a '93 Caravan 3.0 litre that runs like a top; it does, however, suffer from age related complaints, the most recent of which is a coolant leak. I naturally found this following a much needed cooling system flush. The leak appears to be coming from the pipe on the return side to the radiator. The hose is new, and the little pipe it comes off of appears to be in good shape, so if I had to guess, I would say the o-ring on the engine side of the pipe is shot. My question is this: How do you replace it? Visibility is nil when it comes to seeing just how to get at it.   Many thanks in advance for any input,   Mosander Replies to this message: crackorn (May 04, 2008 9:04 am)
#35 of 51 fan motors not working by dmains Apr 20, 2008 (10:29 am)
The fan motors on my 1999 voyager are not working. Fuse is good. Where do I look from here?   Thank you Replies to this message: srs_49 (Apr 20, 2008 1:57 pm)

Replying to: dmains (Apr 20, 2008 10:29 am) Could be the fan relay. Pull the connector off the fan and, probe the connector pins with a voltmeter. When you think the fan should be coming on (by looking at your temperature gauge), i think their should be 12V across the pins.   Another thing you could do is to try and apply 12V directly to the fan motor (after taking off the connector) and see if the fan spins. Need to be careful if you do this using the battery, however, 'cause a short might melt the wires you were using.   The purpose of these two experiments is to try and isolate the problem to either the fan motor itself or the controlling relay, sensor, and associated wiring.
#37 of 51 99 voyager cooling fans relay by dmains Apr 21, 2008 (4:59 am)
I cannot seem to locate the relay for the radiator cooling fans. Would appreciate some help in finding the relay.   Thanks Replies to this message: jrcaracci (Apr 21, 2008 12:14 pm) sdavis1982 (Jun 06, 2009 3:39 pm) pmary (Jun 06, 2009 7:46 pm)

Replying to: dmains (Apr 21, 2008 4:59 am) My 2001 had the relay between the front of the radiator and the grill on the cross bar, drivers side. Take the six screws off the top of the grill and you can spread it enough to get a hand on the relay to pull out the plugs. Helps also if you remove bolt on top of cover, driver side of radiator that holds down the plastic cover. Gives you more room without taking out the whole grill. Could not find the right part anywhere on line or at Local auto supply shops(Autozone and Murrays).. Best bet is to go to Dodge or Chrysler dealer for the part and they will also help you locate and give tips at getting to the part.   Hope this helps. I just replaced mine last week. My problem was that the fans would not shut off, so I had to pull the 40A relay in the fuse box. Replies to this message: sdavis1982 (Jun 06, 2009 3:39 pm) pmary (Jun 06, 2009 7:46 pm)

#40 of 51 Radiator fans are runing on all the time by tecguy Jun 08, 2008 (6:25 pm)
I have a 2003 Dodge caravan and the radiator fans are coming on all on their own, even with no keys in the ignition.Error code (P1491-Radiator fan control relay circuit) I suspect it is the relay myself. any help is ... Replies to this message: jrcaracci (Jun 09, 2008 4:44 pm)

Replying to: tecguy (Jun 08, 2008 6:25 pm) Same happened to my daughters 2001 Town&Country. Answer should be in #38 on this list and the answer I got in #31. The relay is between the radiator and the grill in the 2001 and probably on your 2003. Could only find the right relay at a Chrysler/dodge dealer. It costs about $65 if you install it yourself. Check with your dealer to make sure the relay is located the same as my 2001 model.
