Read articles →A step-by-step installation walkthrough produced by the heater's manufacturer, covering wiring harness routing, P-clip placement, coolant hose cuts and T-fitting splices, clearance around exhaust and sharp edges, and shutoff valve positioning specific to the Mahindra 1626. It follows the actual install sequence closely and flags common mistakes. Most useful to someone who already owns a Curtis cab heater and wants guided help through the physical installation.
Posted by Curtis Industries LLC, the manufacturer of the heater being installed, so the video serves as a branded how-to rather than an independent review.
Run the power harness over the cowl with P-clips, leave a six-inch loop for the wiper, then run it down the side frame with three more P-clips before connecting to the engine.
Cut the lower radiator hose in the middle of its straight section after draining coolant, then install a T-fitting and connect the heater hose with a small hose clamp.
Secure hoses with wire ties and trim lock away from the exhaust, sharp metal braces, and perforated steel, leaving slack so they do not rub.
An inline shutoff valve lets you stop the heater from getting hot in summer; it can be spliced in anywhere along the hose near the thermostat housing.
