About Car Thermostat

Our car thermostat range is built from established UK suppliers and trusted aftermarket brands. Each product is mapped against OE/OEM references and TecDoc ktype data so the reg-lookup above filters to only the parts that fit your specific make, model, engine and trim.

Engine and cooling system parts

Engine and cooling parts span a wide spectrum — timing belts and chains, water pumps, alternators, starters, gaskets and seals. Some are service-interval items (timing belt every 5-10 years or 60-100k miles depending on engine), others are catch-it-early items where small failures can lead to bigger ones if ignored.

Common engine warning signs

• Whining or rattling from the front of the engine — failing belt tensioner or alternator bearing.
• Coolant loss with no visible leak — head gasket, hose or water pump seal.
• Charging warning light or dim headlights at idle — alternator output dropping.
• Slow cranking on cold mornings — starter motor or battery, both worth checking.

Don't postpone a timing-belt service

The biggest avoidable engine failure on the UK fleet is timing-belt overrun. If your service book is missing or the previous owner's record is unclear, get it checked — replacing a belt costs a few hundred pounds; replacing the engine after a belt snap on an interference engine runs into thousands.
