In addition, the cooling system must be bled of air at the intervals specified in the periodic maintenance and lubrication chart. EWS00390 WARNING Do not remove the radiator cap when the engine is hot. Scalding hot fluid and steam may be blown out under pressure, which could cause serious injury. When the engine has cooled, place a thick rag or towel over the radiator cap, and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual pressure to escape. When the hissing sound has stopped, press down on the cap while turning counterclockwise and remove it.

If oil is leaking, immediately turn the engine off and make sure that the engine oil drain bolt, oil tank drain bolt, cylinder head cap, and the oil filler cap are installed correctly. 18. Turn the engine off, and then connect the oil level gauge coupler. 52
