When I put water in the radiator it flows out as quick as I pour it in. The reservoir is also empty. What is possibly the problem?
If water is coming out as quickly as you are pouring it in, you have a major leak. Look under the van, find where it's coming from.
Likely candidates for a leak this big are:
- radiator drain plug. Located at the bottom of the radiator (driver side, if I'm not mistaken), it may be open or defective.
- one of your radiator hoses, likely the lower one. Squeeze it to look for cracks, make sure it is snug at both ends.
- could be a hole in the radiator. Remove the cooling fans to have visual access to the back of the radiator.
