    antifreeze leak Grand Caravan

    Have a slow drip of coolant on my 1999 grand caravan on the passenger side.

    Its dripping onto the plastic shielding in the upper corner in front of the the wheel about a foot in from the side.

    I cant see anything topside of leakage near the belts or anywhere inside the engine bay by flashlight.

    have any ideas?

    Trying to determine how much this is going to cost me cause im pretty mechanically stupid

    It is likely from the water pump dripping onto the splash shield. I would take a look at it, they have a weep hole on the bottom.

    but isn't the water pump further inside the engine bay next to the timing chain?

    This is right up in the front left corner almost under the pressure overflow tank but i don't see anything indicating a leak from there.

    Is the drip green? Is the coolant level low? Could it be the windshield washer tank leaking?

    The coolant blows around from the moving belts. I had a leak in the same area, it was the pump. Have someone put it on the lift

    Get it on a lift as Philip suggests. Shops will usually take a look on your behalf for free. Water pump is most likely culprit. Maybe a small slit in the bypass hose a little lower. Hopefully your ride is a 3.3 or 3.8 liter.

    I had a leak that sounded similar, and it was not the pump. It was the radiator leaking.

    Yes it is a 3.3 and i know its the antifreeze as my temps get hot and i have to add about a gallon of water/fluid to top it off every time.

    After i top it off it takes a few days to get low again.

    Thanks for all of the assistance hopefully it wont get too costly to replace the pump i don't know how much that would cost me ill have to call around some.

    Money is tight at the moment ill have to wait a week or so till i can get it into a shop to get it looked at.

    Think ill be ok for a week limping it along on only short trips to the store no long drives ?

    I hope its not the radiator that will set me back a bit more than merely needing to swap out the pump or a hose.

    Just changed out my waterpump on my '00 Grand Caravan last night (3.8L), it's only $20-25 for the pump, and easy to DIY. Bolts are 10mm for pump body, 13mm for pulley, and a 15mm box wrench to loosen the tensioner to remove the belt. There are small holes on the pulley to stick a screwdriver thru (to keep it from spinning) to take the pulley bolts off. Couple of hours max to do it. It sounds like you already got the antifreeze so go at it.
