Changing Your Coolant Boost Pump
With the new pump in place, reinstall the hose to the left first. Get the band clamp nice and loose on the hose and slip the hose onto the fitting on the pump. You may need to twist and wiggle the hose to get it securely in place. Position the band clamp on the pump side of the raised lip of the fitting and tighten it down with a flathead screwdriver. Repeat the process with the copper pipe and reconnect the Quick Connector on the power cord.

- This video details the process of swapping out the boost pump in your van.
- Make sure the engine is cold before attempting to follow these instructions.
- Hot coolant can burn and injure you. If you are not comfortable performing this part replacement, contact a service professional for assistance.
- Open then close the radiator cap in the engine compartment of your van to depressurize the coolant system.
- Remove the tanks from your van. The video on how to do this is in related videos below.
- The boost pump is located at the bottom of the back wall of the plumbing side underneath the heater unit in your van.
- Disconnect the quick connect on the pump's power cord.
- Slide the insulation back on the lefthand hose to expose the heater hose.
- If this hose feels warm to the touch, the coolant is still too hot.
- Once cool, use a clamp to pinch the lefthand heater hose shut.
- Spilling some coolant is unavoidable, you may want to place a towel to catch it.
- Use a flathead screwdriver to loosen the band clamp on the top of the pump connected to the copper pipe coming out of the bottom of the heater unit. Don't remove the hose just yet. Get the band clamp loose enough to slide on the hose, but leave it in place. Loosen the band clamp on the hose to the left until it can slide on that hose as well. When both band clamps are loose, pull the pump free from both connections. The hose on the lefthand side may be snug and you may need to twist or wiggle the hose to get the pump free.
