Shop parts for a 1982 Suzuki RM60 Dirt Bike.
Keeping your 1982 Suzuki RM60 running cool and efficient requires periodic coolant changes. This dirt bike features a straightforward, air-cooled engine, yet over the decades, some owners may have installed aftermarket liquid-cooled cylinder kits. This guide covers both the stock configuration and considerations for customized cooling systems, so owners can perform this vital maintenance confidently.
Tools & Supplies Needed
- Screwdrivers (flat & Phillips)
- Socket set
- Drain pan
- Coolant compatible with two-stroke dirt bikes (pre-mixed or distilled water to mix if necessary)
- Funnel
- Shop towels
- Latex gloves
Step-by-Step Guide to Changing Coolant
- Let the engine cool completely before beginning. Removing the radiator cap from a hot bike can cause burns or injure you due to pressurized fluid.
- Access the radiator and reservoir (if equipped). Remove any bodywork or plastics if your RM60 is equipped with a liquid cooling kit–stock bikes will not have a radiator. For aftermarket cooling kits, locate the radiator cap and overflow reservoir.
- Open the radiator cap carefully. Place a drain pan underneath the radiator or water pump area.
- Remove the drain bolt located at the bottom of the radiator or at the water pump housing. Let all coolant drain out. If your model has a coolant reservoir, disconnect and drain this as well–rinse with water if contaminated.
- Inspect hoses and clamps for signs of wear, cracks, or brittleness. On a vintage RM60, rubber components can deteriorate with age; replace as necessary for safety and reliability.
- Replace the drain bolt & gasket once drained. Tighten securely to avoid leaks.
- Fill with fresh coolant using a funnel. If using concentrated coolant, mix with distilled water according to the packaging (usually 50/50). Fill to the base of the radiator filler neck. Also, fill the reservoir to the upper level marker if present.
- Burp the cooling system by starting the engine (with radiator cap off) and letting it run for a few minutes. Gently rock the bike or blip the throttle to help remove air bubbles. Watch for coolant movement and air escaping. Top off the coolant as needed until it remains stable at the full mark. Replace the radiator cap.
- Inspect for leaks around the drain bolt, hoses, and radiator. Run the bike up to operating temperature, then allow to fully cool and recheck levels.
- Dispose of old coolant properly at a recycling center or auto parts store–do not pour into the ground or drains.
Essential Notes for 1982 Suzuki RM60 Owners
- Stock RM60 models are generally air-cooled. If your bike is liquid-cooled, aftermarket modifications are present. Check your system for correct kit installation, as some require unique or proprietary radiators, hoses, and caps.
- Rubber hoses and seals on a 40+ year old dirt bike are especially prone to age-related failure. Inspect and replace components to avoid coolant loss.
- Coolant choice matters—use a non-silicate, pre-mixed motorcycle coolant to prevent corrosion and cavitation in aluminum parts. Never use plain tap water as it introduces minerals and contaminants that accelerate wear.
- System capacity varies. Aftermarket radiator kits often hold 700–950 ml. Do not overfill; check your specific kit instructions if available.
- Recurring coolant loss or air bubbles suggest leaks or head gasket issues. Monitor coolant levels post-service and address persistent drops promptly.
