Coolant
If coolant has to be added frequently then the cooling system should be inspected and pressure tested for leaks. See your authorized dealer
Check freeze point of coolant in surge tank. Maintain a 50/50 coolant concentration mix of ethylene glycol (minimum) with recommended antifreeze and coolant conditioner for proper corrosion protection of cooling system. Add coolant to surge tank as necessary.
