Engine Heater Thermosiphon Preheater For Diesel And Gas Engines Weather Tight Coolant Preheater With Thermostat No Pump Needed Fits 350 To 500 CID 5.7 To 8.2L For Trucks Marine And Construction Equipment With 1 Year Warranty

Single unit thermosiphon engine preheater 5.7-8.2L
✔️ 208V, 1.5 kW, 7.2A, 60Hz, thermostat control; fits 350-500 CID

The weather-tight coolant preheater uses a thermosiphon flow to warm engine coolant before cold starts. It’s designed for diesel and gasoline engines in trucks, marine craft, and construction equipment, with a displacement range of 5.7-8.2 liters (350-500 CID). A thermostat keeps the outlet temperature within a reliable range, and no pump is required.
