Coolant Outlets

Plastic housings and outlets play an important role in automotive design, widely used and offering cost efficiency and flexibility across applications. However, in restricted engine bay environments, they have their service limits – lack of maintenance and failure of other components in the cooling system can lead to secondary failure of one or more plastic coolant housings, which then require replacement.
Serck Automotive offers the widest available range of replacement parts, including thermostat housings, coolant outlets, coolant pipes and thermostat covers.

Heater Matrix

A heater Matrix, often referred as a heater core, is a crucial component in a car heating system.
The heater matrix is essentially a small radiator located inside the car’s dashboard. Its primary function is to warm up the air that blows into the Cabin.
Hot coolant from the engine circulates through the heater matrix. This coolant is the same that’s used to cool the engine, but here it serves a dual purpose by providing heat.
Air from outside or recirculated air from inside the car passes over the hot heater matrix. The air absorbs heat from the matrix, gets warmed up, and then is blown into the car’s interior through vents controlled by the heating system.
All components are vigorously tested under stringent operating conditions to ensure quality and longevity.
- Lightweight, Aluminium construction
- Highly efficient performance
- Excellent parc coverage
- Includes seals, fittings and pipes, where applicable
- High stockholding for consistent availability
Heater Blowers

Interior blowers are a critical part of a vehicle’s climate control system, ensuring the correct amount of ambient air intake to be distributed throughout the cabin. These electrical devices are considered fragile, due to plastic elements, and sensitive to vehicle system failures. We offer a range of OE equivalent specification parts to sit most models.
- Competitive range across all popular vehicles across car and van

Heater Resistors

Heater resistors – or heater blower motor resistors – control the fan speed of the interior heater, and as one of the most commonly used cabin functions, they are liable to wear out over time. We offer a range of heater resistors and pre-resistors (radiator fan resistors), which also require replacement once they wear out to ensure that radiator fans are working correctly.
