Single coolant preheater for diesel and gas engines
✔️ 240 volt 1.5 kilowatt heater fits 8 to 12 liter engines

This heavy duty coolant preheater keeps your engine warm during freezing weather without adding extra moving parts. You typically mount it in fleet trucks, construction machines, marine vessels, or standby power units where cold starts wreck components. The thermosiphon flow moves heat straight through the block so you save money on fuel and oil changes.

✅ Operates on 240 volts single phase power
✅ Triggers warming cycle at 100 degrees and shuts off at 120
✅ Pulls roughly 6 amps while running smoothly
✅ Handles motor blocks ranging from 500 to 750 cubic inches

💡 Why is a coolant preheater necessary for diesel engines in cold climates?
The primary function is simple: it maintains consistent fluid temperature so mechanical wear stays low when outdoor temps drop.
- Prevents thick lubricants from blocking critical pathways during startup
- Keeps internal metal components expanded evenly to avoid warping
- Acts as a handy safeguard for standby generators parked outdoors
- Reduces overall maintenance bills by cutting friction and sludge buildup
