About that.... VX in shop. Symptom: engine stopped while driving 25mph w/ no shutdown of electrical. Would not start after. Starter sounded different (about half the repetition of normal with high pitch sound.) Diagnosis: Timing belt broke. Upon replacement it was suggested that Water Pump be replaced. I agreed. Secondary symptoms: Engine ran hot and tranny overheated under load several times. Smells like a hot exhaust but from the tranny as evidenced by the rough shifting and slippage. Have replaced tranny fluid and filter once a year for two years. Engine has 130K. VX still not fixed due to confusion on an interference or non-interference engine causing possible valve damage leading to misfire upon belt replacement. Have yet to diagnose electrical being as plugs were replaced by the mechanics. Moral of the story: If you suspect bad water pump replace, and I agree replace timing belt as well. Or else the built up heat over mileage WILL lead to broken belt, excessive wear on tranny, ultimate failure of both engine and tranny and a whole lot of headaches. And beware of that mode selector switch as it may have failed due to the excessive heat from the tranny as a result of a water pump that should have been replaced before I bought this badass moon buggy.
