Frequently Asked Questions
What is the primary function of this thermostat?
Its primary function is to regulate the engine's coolant temperature by opening and closing to control the flow of coolant to the heat exchanger or raw water pickup, ensuring the engine operates within its designed temperature range.
At what temperature does this Dometic thermostat open?
This Dometic thermostat begins to open at 160°F.
Can I use a thermostat with a different opening temperature?
While technically possible, it is strongly advised to use the thermostat specified by the engine manufacturer. Using a different opening temperature can lead to inefficient operation, increased wear, or overheating.
What are the physical dimensions of this thermostat?
Specific physical dimensions beyond the opening temperature are not provided in the available specifications for this unit.
How often should a marine thermostat be replaced?
Marine thermostats are typically recommended for replacement every 1-3 years or as per the manufacturer's service intervals, as they can become fouled or stick due to marine growth and debris.
