On bitter mornings, you don't want to fight with an engine that cranks slow and strains your starter. This 1,500-watt circulating heater keeps coolant warm and flowing so your rig starts right up and parts stay protected all winter long.
On freezing mornings, engines strain when coolant is cold and oil thickens. This 1,500-watt circulating heater keeps warm coolant moving so oil and diesel stay fluid, letting parts glide instead of grind and cutting down on the wear that comes with hard starts. An internal thermostat maintains coolant between 147F and 185F, giving you steady, controlled warmth without overheating the system.
No two setups are the same, especially when you're working around hoses, filters, and tight clearances. That's why this heater's cylindrical body, universal install strap, and built-in check valve are designed to fit a wide range of plumbing layouts. With the check valve in place, coolant stays put when the heater's off, so you're not starting from an empty system the next cold morning. A detachable power cord makes routing easier, while the top-side connection keeps the plug clear of road spray and chemicals.
