Driving an automobile powered by a diesel engine definitely saves you a lot of cash because it is very cost-effective in terms of fuel consumption. However, this well-loved trait can also bring you a few drawbacks. You see, since diesel engines are more fuel efficient, they tend to produce very little waste heat that can be used to provide warmth inside your vehicle's cabin during cold days. To make up for this, most vehicle manufacturers attach a heavy-duty auxiliary heater, which can produce enough heat to warm up your interiors. This particular component comes in a lot of varieties and you can choose one depending on what vehicle make and model you drive. For instance, it can either have a 2 or 3 speed fan, and it can also be a 12 or 24 bolt model. If you don't have this component within your system, you can always attach one yourself anytime you want. Performing a DIY can make the task a lot cheaper as compared to hiring a professional to do the job. Just make sure that you have the proper tools and hardware needed to make the job easy and quick.

How to Install an Auxiliary Heater

Engine builders have long been aware that one of the best ways to generate heat inside a vehicle's cabin is by installing an auxiliary heater. Unlike other heating components, auxiliary heaters cut idling time and fuel consumption. With these benefits, we won't be surprised if you're planning to install an auxiliary heater in your vehicle as well. For the right way to install an auxiliary heater, you just have to read the instructions below.

Difficulty level: Difficult

Tools needed:

  • Extra nylon ties
  • Auxiliary heater
  • Center punch
  • Dielectric grease
  • Power drill
  • Pliers
  • Self-tapping screws
  • Duct tubes
  • Thermostat

Step 1: Find a good location where the auxiliary heater will be mounted. If you're driving a truck, install the auxiliary heater inside the cargo box. Make sure that the auxiliary heater can be accessible from the ground so you can perform routine maintenance procedures.

Step 2: Using a center punch, drill holes for the ductwork, combustion, and wiring harness in the cargo box. To make this process easier, use the template that's included in the auxiliary heater kit. Note: Don't forget to create some clearance between the auxiliary heater and any parts in the mounting location before you begin drilling.

Step 3: Before installing the auxiliary heater in its mounting location, assemble it first with its mounting bracket, intake tubes, wiring harness, and component covers.

Step 4: Using a drill bit, drill a hole in the fuel tank so you can install the fuel pick-up pipe. Once done with drilling, remove the metal slug using pliers. The distance between the hole and the bottom of the tank shouldn't exceed two inches.

Step 5: Using a power drill, drill a hole near the cargo box where the thermostat will be installed.

Step 6: Cut the pickup-up pipe so it would fit the two-inch distance between the hole and the bottom of the fuel tank. Install the pick-up pipe, and make sure that you won't drop anything into the fuel tank.

Step 7: Put the auxiliary heater over the hole in the floor of the cargo box. While doing so, thread the intake and exhaust tubes through the hole. When the auxiliary heater is already in place, secure it using self-tapping screws.

Step 8: Secure the exhaust pipe and the intake tube by spacing their mounting clamps properly. Remember to put the exhaust pipe and intake tube as far away as possible from materials such as rubber and plastic. Make sure that both the intake tube and exhaust pipe are turned down so that water and contaminants won't get inside.

Step 9: Connect the auxiliary heater's power harness to the battery box.

Step 10: Install a heat outlet and air inlet inside the cab or sleeper. The heat outlet is where hot air is removed while the air inlet is where the air is sucked in so the auxiliary heater can operate.

Step 11: Install the fuel pump near the cargo box where the auxiliary heater is placed. Make sure that the distance between the heater and the exhaust tube is at least three inches.

Step 12: Install the thermostat. Make sure that its wiring harness is connected to the heater's main wiring harness. When installing the thermostat, make sure that the area where it's going to be placed doesn't have any components. Use nylon ties to secure the wiring harness of the auxiliary heater.

Step 13: Check the newly installed auxiliary heater by starting your vehicle's engine. If the component doesn't work, it needs to be cycled on and off so it can draw enough fuel.

Installing an auxiliary heater takes around six to eight hours for an expert DIYer. Don't forget to periodically clean the unit's mounting enclosure, and make sure to activate it even during the summer months.
