Ok so i noticed a small leak coming from the rear cylinder. the leak is coming from the coolant line thats connected to the cylinder.its not the actual hose, but the metal pard that connects to the motor. doesnt seem to be leaking alot but still something im concernd about. im sure theres threads on here exlpaining my issue but cant seem to locate them.

Maybe it's leaking where the hose connects - is the clamp tight?

I gave the clamp a good tightening after noticing that was the source of the leak. The hose was in good shape so i hope hope this cures my problem. I put about 1200 mi a month on my 9 so i want to make sure shes rinning in top shape.

Hey Bobby,

Have you had some cold weather lately out there in sunny Cali?

Coolant leaks always seem to pop up in cold weather. The molecular structure of antifreeze reacts to cold by shrinking.

My 900 developed a coolant leak in cold weather. I used a small socket to tighten all of the coolant clamps I could find; some of them were pretty loose too.

Tighten all of your hose clamps and your leak should go away.

You probably got it. This is a very common occurence with the 9s. Mine did it and once I tightened the clamp it was done.
