#45 of 51 2005 Dodge Caravan Leak by Dodge2005 Jan 19, 2009 (10:21 am)
I have a 2005 Dodge Grand Caravan with 85k and seems to be leaking antifreeze. Is this common?   Will leak stop fix it? Replies to this message: shipo (Jan 19, 2009 10:45 am) xwesx (Jan 20, 2009 8:51 am)

Replying to: Dodge2005 (Jan 19, 2009 10:21 am) "Is this common?" No.   "Will leak stop fix it?" Maybe, maybe not, it depends upon what's leaking. Replies to this message: xwesx (Jan 20, 2009 8:51 am)

Replying to: shipo (Jan 19, 2009 10:45 am) Any idea from where your leak is coming? As Shipo said, it depends on what is leaking. Also, depending on what is leaking, it may be easier/preferable to fix the leak rather than put an additive in the coolant.

Replying to: jrcaracci (Apr 21, 2008 12:14 pm) I have an 02 caravan with error code p1491, I replaced the fuses and the relay but the fans keep coming on even with the ignition off until eventually the battery is drained. Does anyone have a fix for this? Replies to this message: pmary (Jun 06, 2009 7:46 pm)

Replying to: sdavis1982 (Jun 06, 2009 3:39 pm) Hi,      I used to get the P1491 code on my 01 Caravan before I changed my leaky engine cooling radiator. It seemed that coolant was draining on to the wire leading to the far fan motor creating a grounding short. Some of the wire insulation was cracked so I graffted in a new section. The old rad looked okay until I took it out and and the the hot side tank was corroded along the fins. There is 2 other small rads (tranny& AC) that hang off the front of the engine rad and 2 electric fans. It took me a couple hours and a 6 pack of beer to fix it! The fan relay was behind the rad on top of the cross beam on the driver's side. I had to remove the head lamp module to access it.

Replying to: jrcaracci (Mar 20, 2008 4:21 pm) The service manual for 1998 T&C LXi 3.8L is a bit misleading on this. Its still on the drivers side at the bottom inside of the radiator mount just above the inlet hose. No need to pull the headlight as it doesn't buy you anything. You'll have to pull the air cleaner hose and aircleaner holder to get at it. Mine wasn't riveted (thank goodness) and dropped below the the lower bumper flare for easier access after I pulled the 2x 8mm machine screws. The interlock was pesky (slide the orange lock plate near the seal lip to the left and it will release without breaking. I found a $52 Niehoff Ignition Relay RL38851 OE at Kragen/Oreilly's that fit perfect, considerably cheaper than the $96 the dealer wanted for the same thing. Chrysler really needs to rework their design for ease of access. Its one thing to put it here for cooling (theoretically) but really, right above the hotter than heck radiator return hose and down where every puddle can splash it? According to the service department this is a frequently failing item.
