Frequently Asked Questions
The LR031880 heat exchanger transfers heat from the auxiliary fuel-fired heater into the vehicle heating circuit to warm coolant or intake air independently of the main engine. It keeps combustion products isolated from the vehicle fluid circuit; blockage, corrosion or cracking reduce heat transfer and can permit cross-contamination, so inspect regularly and replace if damaged.
