    2001 w900 c15 6nz cat. Noticed this morning coolant is leaking past cap on surge tank. Any ideas what would cause this? Cap is about 2 months old. And is 10 lbs.

    Get a rad. press. tester and bring eng. up to op. temp with tester on in place of cap to see if it is building up lots of press. in rad. a oil sample test will tell you if anything is in oil yet?
