I have a question
Could water left in a block's water passages over the winter cause the block to crack.
Thanks |

If it will most definitely cause it to crack.
Drain the block, exhaust, etc. from every possible location and run some RV coolant through it. |

A few years ago I kept a count of cracked blocks on this site caused by poor winterizing: 26 plus. Yup, water will wreck a motor if allowed to freeze.

jhelms, I like.so many others. have a heating problem. I have a 1981 318 Chrysler in my Skiff Craft. I have overhauled the raw water pump, installed a new engine water pump and replaced the thermostat with a 160 deg. and it still runs hot according to the guage. The manifolds are cool and I can still put my hands on the block and it won't burn me. Can anyone give me any more advice. I have only tested the engine with a Fake a Lake connection. Thakns |

You might be okay, and your gage lying to you. Hard to keep your hand on anything over 140 'F, and that's cool.
Someone add my usual message on infrared temp gages here, please!

RE: "replaced the thermostat with a 160 deg."
Was the existing t'stat a different value? |

are you losing coolant in the heat exchanger (if FWC)? check the levels from one cruise to the next. if the level drops, your heat exchanger may be corroded and mixing coolant with sea water and the running out the exhaust. That happened on my boat and it caused one motor to run 20degrees hotter than the other. never overheated big time but it did run a bit hotter.
gotta get my heat exchanger rebuilt. |

I bought a boat at auction with the drain plugs in and freeze plugs laying in the bilge. So I suspected the motor was toast. Started it up and filled the oil pan with water in about 20 seconds. They can and will crack. I thought I had a cheap replacement when a marina owner took possesion of an abandoned twin engine houseboat with 318's with only 680hrs. Guess what, plugs were left in and the freeze plugs were laying in the bilge. My search continues. |
