WARNING
NEVER OPEN THE EXPANSION TANK CAP WHEN THE ENGINE IS
OPERATING OR HOT. IT COULD RESULT IN SERIOUS PERSONAL
INJURY AND MAY CAUSE ENGINE DAMAGE.
REMOVING AIR BUBBLES IN COOLANT
• Start the engine and warm it up at a low rpm.
• Stop the engine and allow the engine to cool,
then open the cap of the expansion tank
carefully.
*NOTE: Never open the cap when the engine is
hot. It may cause scalding.
• Refill with coolant if needed.
• Reinstall the expansion tank cap
• Check the level of the expansion tank regularly.
CABIN HEATER CONNECTION
• In order to use a cabin heater, an extra coolant
circulation pump is needed.
• After connecting cabin heater lines, engine
coolant must be refilled and checked.
• Check coolant flow direction, as shown in the
drawing.
• If a cabin heater is installed, the volume of the
cooling circuit will be increased. It may be
necessary to add an additional expansion tank to
avoid losing cooling water as the expansion tank
on the engine may not have sufficient capacity.
• Contact your Hyundai SeasAll dealer if you have
any concerns.
