Dodge Caravan coolant leaking on the right side of engine

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????

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.

I have a 1999 Plymouth Voyager van that is leaking engine coolant. upon closer look, it appears to be coming from an oval hole on the block of the engine, located on the passenger side near the back of the block....
coolant streams out even when engine is not running
any ideas

The oval recess in the block is called a freeze plug. It is an expansion plug designed to protect the engine from freeze damage. Many mechaics agree that the so called "long term" coolant, should not be used too long. the coolant corrodes the plug from the inside. This can be a DIY, but as much as I like to do it myself, I had a mechanic do it for less than $100. This was 2 years, 26,000 miles ago, and have had no more problems.
