Warm It Up
Warming up the M160 gives the oil time to lubricate the vehicle’s parts. It also
lets the engine warm up enough to boil off condensation caused by normal engine
breathing. That way, you won’t have to worry about condensation mixing with the
oil and forming a sludge that’ll clog the engine.
So, once the M160 is warmed up and operating, check these readings, especially
those for water temperature and engine oil pressure. They should be within normal
operating range.
Cool It Down
After operation, let the M160 cool down before shutting it off. Idle the M160 for
2–3 minutes. The engine needs to cool down after operations to prevent excessive
heat in the engine, particularly in the turbocharger center housing.
Overheating can crack the block, warp a head or valves, or bake the oil until it’s
not slick enough to lube the bearings. Cooling down also lets the turbocharger slow
down, reducing coking in the turbocharger bearings.
