6-1 Periodic Checks
Making Daily Checks
• Check fluid level; add fluid as needed.
• Check all connecting lines, hoses, and connectors for wear or
damage.
Making Monthly Checks
• Check for leaks developing at the pump seal, gaskets, and other
similar locations.
• Check the pump drive V belt for any wear.
• Check the reservoir tank vent for any obstructions.
Making Quarterly Checks
• Check the heat transfer fluid for deterioration. If the fluid is
noticeably darker, or it seems significantly thicker, drain the

every three (3) months, whichever comes first. Contact the Service
Department for information on fluid testing.
