The heater core is also known as the heater matrix. It works in a similar way to the car radiator but, instead of removing heat to the outside air it transfers heat to the vehicle interior thereby helping to keep you warm.
Why Heater Cores Fail
More often than not a heater core leak will be the result of poor maintenance leading to corrosion and leakage. You can usually tell if the heater core is leaking because there will be excess condensation on the inside of the windscreen and/or the mats in the foot well will be damp.
K-Seal to the rescue
K-Seal will fix most leaks in the heater core. The heater core is usually located just behind the dashboard making it very difficult, time consuming and expensive to repair. When using K-Seal for this type of repair make sure that the heater is switched to maximum so that K-Seal flows through the pipes and reaches the leak. You can save literally hundreds of pounds.
