Question about 2000 Dodge Caravan

1 Answer

I have a coolant leak coming from the passenger side of the van. It appears to be coming from a part that I am not sure what it is. The lower radiator hose comes from this part, back to the bottom of the radiator. Is this a possible source for the leak, and what is the part called?

    I thought that it was maybe the water pump. Thanks for the help!

The water pump is connected to the radiator hose.

3.3L & 3.8L Engines To Remove:
Water pump location (3.3 and 3.8L engines) I have a coolant leak coming from the passenger - 91153g21.gif

  1. Disconnect the negative battery cable.
  2. Drain the cooling system.
  3. Remove the serpentine belt.
  4. Raise and safely support the vehicle. Remove the right front wheel and lower fender shield.
  5. Remove the water pump pulley.
  6. Remove the five mounting bolts and remove the pump from the engine.
  7. Discard the O-ring. Clean the O-ring sealing surface and inspect the water pump for damage, cracks, seal leaks, and loose or rough turning bearings.
When installing the pump, make sure that the O-ring is properly seated in the groove in the pump body (3.3 and 3.8L engines) 91153g22.gif

To Install:
  1. Install a new O-ring into the water pump groove. Install the pump onto the engine. Tighten the mounting bolts to 108 in. lbs. (12 Nm).
  2. Install the water pump pulley. Tighten the water pump pulley bolts to 20 ft. lbs. (28 Nm).
  3. Install the fender shield and wheel. Tighten the wheel lug nuts, in sequence, to 95 ft. lbs. (129 Nm). Lower the vehicle.
  4. Install the serpentine belt.
  5. Refill the cooling system to the correct level with a 50/50 mixture of clean, ethylene glycol antifreeze and water. Bleed the cooling system.
  6. Reconnect the negative battery cable, run the vehicle until the thermostat opens, fill the overflow tank and check for leaks.
  7. Once the vehicle has cooled, recheck the coolant level.

Leaks coolant under van down the frame rail on passenger side even on the outside of the passenger front door


The door is getting spray from the leak coming from the engine compartment. The easiest way to find the leak is to use a pressure testing device. Check with autoparts store see if you can rent one because they are not cheap.

Passenger side coolant leak


I'd have to see it in person to comment. The water pump is on the passenger side of the van.
A mechanic would fill the cooling system then pressure test it for leaks.

Cant stop a 201venture van from over heating the heater works the van dont run hot but wen the heater dont heat the motor runs hot


When your not feeling heat coming from the heater it usually means that the coolant level is too low in the radiator. It sounds like you have a coolant leak somewhere which is causing your overheating problem. Fill your radiator and let the engine run for about a half hour with the radiator cap on tight. Then turn off the engine and check for any leaks under the van. If you don't see any leaks under the van then see if the carpeting is wet on the passenger side of the vehicle. If the carpet is wet and it smells like anti-freeze you have a heater core that is leaking. I hope this helps you. :)

Coolant is leaking from what appears to be a hose stub sticking out of the passenger side firewall.


Are you sure it's not water. It could be a drain for the cowl (rain water). If it is coolant it's coming from the heater core and hose should be changed. Good luck

2000 Chrysler Town and Country Antifreeze leak


I would replace the Thermostat and see if that will not Stop this. It is Coming from the Overflow Tank. It is getting a Little Warm during Driving and the Extra Coolant that will Build up Preassure needs somewhere to go So, It sends it to the Overflow Reservoir and it Seeps out the Overflow Outlet. This is Pretty Common though and Really not that Big of a Deal as long as you do not loose too Much. Please Rate My Response! Thanks!
