#1 of 13 Dodge Caravan coolant leaking on the right side of engine
Jun 28, 2009 (7:37 am)
I kept finding my coolant leaking. But I cannot locate where the leak was. Yesterday the first time the temprature went to roof. I stopped the van immediately and then I heard the steam buzz. I looked at the bottom of the van and found the steam came from the the passenger side after the engine. And the coolant was completely gone. I added two gallans of the coolant and made it home. Is it the water pump o-ring problem? How difficulty to change it?

I found where the leak is. There are two lines of pipes across from the front to the back. Each line is composed of one solid metal pipe connect to the engine, a 8 inches rubber pipe and another solid metal pipe to the back. Just before the rubble pipe, the erosion eats the metal pipe. If the car is not running, no leaking. When the car is running, the pressure makes leaking. How do I replace the metal pipe?

It's funny you mentioned this. We just had the same pipes replaced last week on our 01 DGC with 114K, because of corrosion. We had no leaks, but they were rusted pretty bad and have been doing so for the past few years. (I've had my share of this kind of problem from my old cars, when pipes under it rusted out. So I learned my lesson.) It cost us about $500 at the dealer. The replacement pipes are made of non-corrosive metal.

I just noticed today that I have the same problem. What are those pipes called? Yeah I keep putting coolant in my radiator and after a few days its down again.

I don't know what these pipes are called. I guess that they are for colling the backend AC. The way I fixed it costed me less than $2. The hole was just one inch before the rubble pipe. I cut it out and buy the new longer (1 foot) rubble pipe to replace the old rubble pipe.

Mine is right at the fitting. I was thinking about using rubber hose and bypass the metal pipes but I was just curious how much the metal ones were.

They costed around $200 for all parts from the dealer. Those pipes are the coolant that runs to the back of the van for heat. (It runs to another heater coil for the rear heat.) I would caution you to only replace it with metal piping only and not rubber hoses. Since they run under the vechicle, they can get damaged very easily.

Thanks for all the information. How hard is this to do ourselves at home? How long does it take? Would it be a bad decision to get this part used at a junk yard????
#9 of 13 2001 Dodge Caravan Coolant leaking rightaway

I was getting intermittent heat; I checked there was no coolant in the reserrvoir. I added a full bottle. Rightaway, I heard all the reservoir coolant leaked away, even without starting engine. I added coolant to the radiator, and it stayed there. What could be the cause? I will apreiate any input.

It seems fairly obvious that either the reservoir is cracked, or the hose that connects it to the radiator by the pressure cap is broken or detached.
