These movie clips cover the installation of Ventech’s Kit #19; suitable for a MaxxForce 7-powered bus equipped with an A/C compressor. Each clip is 2-3 minutes in duration. Scroll down the page to watch all of the installation movies step-by-step.
Unpack the LHG kit and familiarize yourself with the contents and confirm that all the parts are present.
Next, we begin the actual installation. Clip #2 explains the removal of the serpentine belt and the installation of the LHG mounting brackets.
Installation Brackets are available for many current school bus applications
We now install the LHG heater assembly. The LHG installation can be completed in approximately two hours
After installing the heater assembly, an idler or belt tensioner may be installed, depending on the engine / kit combination. Then, the LHG is plumbed to the existing bus heating system
Before we move on to the electrical installation, simply reinstall the Serpentine Belt.
Once the heater is installed and plumbed, the Electrical Harness, Control Box, and Dashboard Switch need to be installed.
Just a few more steps to go. We’re now going to mount the Driver’s Dashboard Switch that provides a ‘manual override’ of the LHG operation.
The LHG is designed to power up whenever the ambient (outside) temperature is below a certain threshold. The LHG will also disengage once the engine coolant temperature is rapidly raised to 185 Deg.F.
Final steps are to refill the coolant, bleed the system, and check the operation of the Ventech LHG for the first time.
