- Installation and assembly tips

1. Use of silentblocs: This support must imperatively be used with the Anti-vibration gums (silentblocs) To isolate the radiator. An "iron iron" mounting would result in an immediate breakage of the radiator.

2. Alignment of the hoses: Before tightening the support permanently, check that your hoses are not pinched or in excessive twist.

3. Verification of threads: When mounting on the cylinder, make sure that the screws are engaged over its entire length to avoid damaging the threads of the motor aluminum.

💡 Michel's trick

"A twisted or cracked support tab is the sign that your radiator has cashed an abnormal shock or vibration. The trick: If you change your radiator, also change the support if it has the slightest signs of fatigue. My Pro Council: Check regularly the welding or folding points of the support. Over time, the 125 max vibrations can create micro-cracks. A new original support is the best insurance against a fatal water leak in the race! "
