Block Heater for Cummins B3.3 in Snorkal TB60 - MikePhua - 07-03-2025
A discussion on the Panswork forum about using a block heater for the Cummins B3.3 engine in the Snorkal TB60 has sparked significant interest among users. Block heaters are essential for starting engines in cold weather, particularly in low-temperature conditions where starting problems are common. This article summarizes the relevant discussions and provides advice on installing and using a block heater.
Function of the Block Heater
The primary function of a block heater is to warm the engine in cold environments, ensuring smooth startup. For smaller diesel engines like the Cummins B3.3, a block heater helps increase the engine temperature, reducing stress during startup and preventing engine damage due to cold temperatures.
Reasons for Using a Block Heater
- Improved Starting Performance
- Starting a diesel engine in cold weather can be challenging. A block heater warms the engine coolant, ensuring the engine reaches an optimal temperature for starting, reducing wear, and allowing for quicker starts.

- Reducing Engine Damage
- Starting an engine in cold temperatures increases internal friction, especially when coolant and oil have not yet circulated. Using a block heater prevents long-term damage caused by improper startup due to cold conditions.

- Enhanced Fuel Efficiency
- Preheating the engine can also improve fuel efficiency since a warm engine burns fuel more efficiently, reducing waste from incomplete combustion.

- Heater Fails to Start
- If the block heater is not functioning, first check the power supply and ensure the switch is in the "on" position. If the heater still doesn’t work, the heating element may be damaged and needs replacing.

- Ineffective Heating
- If the heater isn't warming effectively, it could be due to insufficient heater power or an aging unit. Consider replacing it with a higher-powered model or check that the coolant is flowing properly.
