While thermostats, thermal switches and temperature sensors are designed to last the service life of an engine and are maintenance-free, they should be exchanged when accidents occur or as a result of external influences.
The advice comes from MAHLE Aftermarket following its expansion into the thermal management market.
What to look for:
1. Do the radiator and/or coolant pump have any obvious defects?
2. Is the coolant hose perished or damaged?
3. Is the water pump drive belt in good condition?
4. Was the cooling system opened beforehand, for example, to change the timing belt or replace the water pump?
5. Is there previous damage caused by thermal overloading or contamination due to previous service or repair work on the system?
The complete range of MAHLE Aftermarket thermostats extends to more than 500 individual part numbers, which represents a huge proportion of the UK vehicle parc.
The range includes traditional thermostat inserts, housing thermostats, map-controlled thermostats, sleeve valve thermostats, oil thermostats and EGR thermostats that regulate the flow of coolant through the EGR cooler.
In addition, MAHLE Aftermarket also supplies a multitude of thermal switches and thermocouples.
