Keeping your 1995 Honda CR80's cooling system in top shape is essential for high performance and engine longevity. Flushing and replacing the coolant ensures your bike stays cool under pressure - both on the trails and the track. Here is MotoSport's proprietary step-by-step guide to changing the coolant on your CR80, with model-specific tips to help you get the job done right.
What You'll Need
- Compatible ethylene glycol-based coolant (Honda-specific or approved for aluminum radiators)
- Basic hand tools (screwdrivers, sockets, wrenches)
- Drain pan
- Cotton rags
- Rubber gloves & eye protection
- Distilled water (for flushing, optional)
Before You Begin
- Never attempt to remove the radiator cap or drain the system while the engine is hot. Severe burns can occur from hot coolant or steam.
- The CR80's compact design means clearance around the radiator can be tight. Give yourself time and space to reach fittings without forcing anything.
- Dispose of old coolant responsibly – it is toxic to humans, animals, & the environment.
Step-by-Step Coolant Change Guide
- Remove the seat and left side shroud to access the radiator and overflow components.
On the CR80, these are held by bolts and sometimes a band. Remove carefully and keep hardware organized for reinstallation. - Place a drain pan under the water pump or radiator drain bolt location.
The drain bolt is typically on the lower side of the engine case or under the water pump cover. Consult your bike's layout and loosen the bolt. If no dedicated drain bolt is visible, disconnect the lower radiator hose where it joins the engine. - Open the radiator cap (with the bike cold.) to let air in and help the coolant drain completely. Let it drain fully into your pan.
- Inspect hoses and clamps for any wear, cracks, or leaks. Replace worn components as needed to avoid future coolant loss.
- Flush the system (optional, but recommended if the coolant is dirty).
Pour distilled water into the radiator, briefly reinstall the cap, and run the engine just long enough to circulate. Turn off, allow to cool, and drain. Repeat until drain water runs clear. - Reinstall the drain bolt or reconnect the hose.
- Fill the radiator slowly with new coolant to the brim.
Use a funnel to avoid spills. The 1995 CR80 only requires a small amount of coolant; consult your owner's manual for exact capacity. - "Burp" the system by gently squeezing hoses with the cap off to help air bubbles escape.
- Fill the overflow reservoir to the correct line. Do not overfill.
- Reinstall radiator cap securely.
- Start the engine and let it run at idle until it reaches operating temperature.
Watch for coolant leaks. As the engine warms, you may notice the coolant level drops slightlystop the engine, let everything cool, and top up as needed. - Reassemble the shroud and seat once no further adjustments are needed.
CR80 Model Notes
- The 1995 CR80 features a lightweight, high-revving engine and a compact, single-radiator cooling system.
- Clearance is tight around the water pump, so be mindful when loosening or tightening bolts not to cross-thread or overtighten.
- Always use coolant compatible with aluminum systems to prevent corrosion and overheating.
- Check for radiator fin damage – bent fins can reduce cooling efficiency, and dirt build-up should be carefully rinsed away during maintenance.
After the Coolant Change
- For the first few rides after a coolant change, monitor the level in both the radiator and reservoir, topping up as needed.
- Inspect for any leaks when the engine is hot and cold. Address issues promptly to protect your engine.
