For any sidelined trucks returning to service, Chris Harrison, general manager, CIT Kenworth, and Scott Dehm, body shop manager, Central Illinois Kenworth, recommend the following steps: 1. Check fuel tanks, lines and filters before putting idled trucks back into service. 2. Do not use diesel additives to treat algae in a fuel tank. 3. Replace damaged fuel tanks with OEM-quality replacement tanks. 4. Check engine oil seals. 5. Examine drive belts, hoses, fittings and adaptors, plus the exhaust system for leaks.
