I have a new-to-me Century Coronado, with an M440 engine. After not seeing water for 3 years, I was amazed that it fired right up and runs very well. But I really want to change the oil. My old Mercruiser was easy: I pumped oil straight out of the dipstick tube. But when I try that on my 440, all I pull is crankcase vapor. Apparently the dipstick tube does not extend down to the bottom of the oil pan. I do see a drainplug on the oil pan. But There is not enough room down there for a catch tray. So how do I remove old oil from this M440? I don't just drain it into the bilge, do I? Can't be. I am sure there is a trick, and I am confident that someone here can share it. Thanks very much. |

if you can figure out a way to use the drain plug, do it. it flushes out all of the sediment at the bottom of the pan. i might try rigging up a funnel and hose system. let the oil drain into the funnel, and run the hose to a catch tray. if that won't work, get a siphon pump with a hose, unscrew the dipstick "holder/tube" form the oil pan, and feed the hose down into the pan. also you might want to consider a can of engine flush to clean all of the sludge out. hope this helps!

I use an oil changing system that is motorized. It is a 3 gallon bucket with an electric pump and switch mounted on the lid. You hook up to your engine battery for power and stick a plastic tube down the oil dipstick to suck the old oil out. They sell for about $125. It sounds like a lot of money, but well worth it. I changed my oil pan gaskets after using it and was happy to see that it got all but about a half a cup of the old oil out. |

I use a pump that attaches to a drill. About $8. the pump fittings are standard garden hose.
Remove the dipstick fitting and a 3/8" i.d. poly tube will fit down the hole into the sump. Warm the engines before pumping. Work the tube back to the lowest part of the pan. The sound will tell you if you are hitting black gold. |

I use a Alloy Marine All U-SUC hand pump about 80 bucks on my 440's. Pump it up, stick the 5ft hose down the dip stick tube into the pan and release the valve and up comes the oil. I tried one of those cheap electric ones and burned out the motor on the first engine because it's hard to get it primed. That went right back to West Marine for a refund. |

I wonder why Chrysler didn't just extend the dipstick tube down into the oil pan, like Mercruisers do. It's so much easier that way: Just suck it out of the dipstick tube. If I snake a tube down inside the dipstick tube, I need to use a wee little tiny tube so it fits. Then its quite difficult to pull even warm oil thru it. |

I was suprised myself how quickly the oil came up from the crankcase. I think it came with another much wider tube too that could be used to clean out a bilge or someother task. It really worked pretty well. |
