Isotemp Water Heater Installation Kit for Promaster, Sprinter & Transit

$249.00$289.00

The installation kit was originally designed for a Ram Promaster, but we have since confirmed that this is also compatible on a Mercedes Sprinter and Ford Transit. Our installation guide shows photos of the kit being installed on a Ram Promaster, however the installation is virtually the same on both Sprinter, Transit and Promaster – the key difference in the procedure for Transit or Sprinter vans is the process of cutting into the van’s coolant lines near the “heater core” and we try to update instruction guide often to show these differences. The components of the kit vary slightly depending on your van type.

You can choose between standard stainless steel hose clamps or Gates PowerGrip heat shrink hose clamps in your kit. We prefer the PowerGrip hose clamps but other installers prefer standard hose clamps. The PowerGrip hose clamps are a bit more expensive which is reflected in the cost of the kits that use that option. The PowerGrip clamps require a heat gun and a bit of a learning curve to install. The standard hose clamps only need basic tools and are easier to remove for any maintenance.

Vanlife Outfitters Isotemp Water Heater Installation Kit for Promaster, Sprinter & Transit Vans

We've taken the mystery and hassle out of installing an Isotemp water heater in your van! If you add on our optional installation kit, you'll get all the fittings, hose and hardware necessary to install the water heater in a typical installation. No need to order all these parts separately and hope that you have the right parts. The kit also comes with very detailed step-by-step guide on how to install the water heater and connect it to your van's coolant lines . The only additional thing you'll need to purchase yourself is the Mopar coolant to top up the system after you install the water heater. Note, our guide does NOT cover plumbing your water lines - only the installation of the water heater itself but we do provide some advice for hooking up your fresh/cold and hot water plumbing.

The installation kit was originally designed for a Ram Promaster, but we have since confirmed that this is also compatible on a Mercedes Sprinter and Ford Transit. Our installation guide shows photos of the kit being installed on a Ram Promaster, however the installation is virtually the same on both Sprinter and Promaster - the key difference in the procedure for Transit or Sprinter vans is the process of cutting into the van's coolant lines near the "heater core" and we try to update instruction guide often to show these differences. The components of the kit vary slightly depending on your van type.

We offer three versions of the kit. The "standard" kit with 50' of coolant hose will work for installations where the water heater is located on the driver side of the van. If you're locating your unit on the passenger side or high off the ground, consider getting the "long" or "extra long" versions of the kit which add some extra hose and related fittings. Full details of what is included in each version of the kit below.
