Next problem.... where's my water pump? 90 caravan 3.0

If you are standing in front of the car, and looking down between the back of the radiator and the front of the engine, the auxiliary water pump will be on the bottom left corner of the back of the radiator.

Behind the water pump pulley

It's located behind the front bumper on the driver's side. You need to disconnect the battery, remove the left front wheel and remove enough of the retainers for the left front wheel well [plastic] shroud, to move the shroud out of the way. This gives you access to the TCM [transmission control module aka transmission computer] Diagram linked below. See

on the front of the engine passenger side towards the axle shaft

The low pressure line and fitting is located between the the a/c compressor and the radiator, left side near the bottom front of the motor.

your water pump is at the front of the motor twards the bottom of the vanlook at the pullys the water pump is the only one that the smooth side of the belt runs on and has three or four bolts on the front of it

Water pump sits in the front of the engine top centerline. Look just below the coil pack. It uses the timing v-belt for operation so it takes a bit of mechanical know how to remove/replace (r&r) it, as the timing can be thrown off if the v-belt is not reinstalled correctly. Get past the timing belt, the water pump is r&r is just a few bolts away. I'm currently babying my water pump...the part is relatively inexpensive compared with an almost $500 labor charge (5hrs, dealer est.) to replace it. I'll be hitting up the dealer as my '93 Audi 90 CS Quattro is a daily driver. G/L
