How to Change the Coolant in a 2013 GAS GAS EC250E
Changing the coolant on your 2013 GAS GAS EC250E is a vital part of routine maintenance, ensuring optimal engine cooling and longer component life. This process is straightforward, but attention to detail is required to protect sensitive engine and radiator components. Below is a unique MotoSport guide for riders looking to perform this service themselves.
What You–ll Need
- Coolant recommended for your EC250E (see owner's manual, typically high-quality premixed ethylene glycol with corrosion inhibitors, 30% mix for cold climates)
- Socket set or spanners
- Drain pan
- Funnel
- Safety gloves and eye protection
- Clean rags
Important Model-Specific Notes
- The EC250E is equipped with an aluminum engine and radiator; only use coolant that contains anti-corrosion properties to avoid premature rust and blockages in the cooling system—never use plain water or non-compatible coolants, as this can damage internal components.
- Check your owner's manual for the recommended coolant type and maintenance interval. For many GAS GAS models, coolant should be replaced regularly for optimal operation–every 1–2 years is commonly advised.
Long-life coolants, such as GRO GCC at a 30% mix, are often recommended for GAS GAS 2-strokes in climates to –18C.
Coolant Change Procedure
- Let the engine cool completely. Never open the radiator cap while the engine is hot, as the cooling system is pressurized and hot coolant can cause severe burns.
- Remove the seat and shrouds as necessary to access the radiator cap and drain plug area.
- Place your drain pan beneath the water pump area on the right side of the engine.
- Remove the radiator cap slowly to release pressure. The cap is typically found on the left or right top side of the radiator.
- Locate and remove the coolant drain bolt. For the 2013 GAS GAS EC250E, the coolant drain bolt is usually situated at the lowest point of the water pump cover (right engine case). Loosen the bolt, allowing coolant to drain into your pan.
- Allow the system to fully drain. Tilt the bike gently side to side to ensure all old coolant exits, including residual liquid in hose and radiator bends.
- Inspect the old coolant. Any signs of oil, rust, or debris may indicate further cooling system or engine issuesconsider additional inspection if contamination is noted.
- Reinstall and torque the drain bolt securely to manufacturer specs. Do not overtighten to avoid damaging the threads or sealing surface.
- Refill the radiators with fresh coolant. Use a funnel and slowly pour coolant into the fill neck until it reaches the top of the radiator core. Squeeze radiator hoses gently to help dislodge air bubbles and ensure complete filling.
- Reinstall the radiator cap carefully.
- Start the engine and let it idle for a few minutes. With the bike safely upright, watch the coolant level before and after as air may burp out—top off as necessary after initial startup and system bleeding.
- Check for leaks at the drain bolt, hoses, and radiator cap area. Also, double-check coolant level after engine has cooled again from your test run.
Tips and Reminders
- Never mix different types or colors of coolant unless confirmed compatible by the manufacturer.
- Worn coolant loses its anti-corrosion performance; err on changing it more frequently for hard-ridden or seldom-used bikes.
- Dispose of used coolant responsibly, as it is hazardous to the environment and animals.
The 2013 GAS GAS EC250E is widely respected for its lightweight chassis and competitive 2-stroke performance. Keeping your cooling system in good condition is one of the simplest ways to ensure reliable rides and consistent engine power all season long.
