Stop fighting your diesel on frozen mornings and get back to work faster.

Heavy-Duty Engine Block Immersion Heater for John Deere Series 350 (4045 PowerTech Plus iT4)

Waking up a 4045 PowerTech Plus in sub-zero temps shouldn't feel like a gamble. The stock cold-start struggle on these iT4 engines puts massive strain on your starter and battery.

Because the Series 350 utilizes the 4.5L 4045 engine architecture, this 27mm immersion heater fits your block perfectly. It replaces the frost plug to heat the coolant directly at the source rather than fighting through the block walls.

This 1000W unit eliminates that "dry start" clatter by keeping the internal vitals warm. You’ll notice smoother idling and immediate oil pressure even when the mercury stays below zero.

Technical Specifications

Why You Need This Upgrade

• Instant Ignition: Prevents the "white smoke" stumble by pre-warming the combustion chambers for cleaner ignition.
• Engine Longevity: Reduces friction-related wear by ensuring oil flows to the turbo and bearings immediately.
• Direct Immersion: The most efficient heating method available, drawing less power than external "tank" style heaters.
• OEM-Grade Seal: Designed for a precision fit into the engine block to prevent coolant seepage during thermal expansion.

Installation & Fitment Notes

This is a direct-fit immersion heater for the 4.5L 4045 platform. You will need to drain your coolant before removing the frost plug or existing heater. Ensure the element is fully submerged and the system is bled of air before applying power to prevent burning out the copper coil.

Protect your investment and eliminate winter downtime with a heater that works as hard as your Deere.
