Hello Patrick,
My engine tends to overheat when I go beyond 2000RPM. Could you point me to the part (sleave) that you are taking about?
Thanks

First, you did not post your name , boat or the engine you have , however if you have a Volvo Tmd22 as I do, then this would apply. If you are overheating it would be a good idea to take out your heat exchanger , it may need cleaning and that may be your problem. I had cleaned mine a couple of times ,yet still had over heating. I only now discovered that there is a rubber ring/seal that slides over the tube and seals an opening inside the header tank , that forces the cooling water/antifreeze to flow thru the heat exchanger , rather than some of it to bypass it. That is why it still cooled the water to a point , but as the heat increased with rpms it could not cool it fast enough. I did not know about this seal as it was not on the tube whenever I pulled it out,it had deteriorated and fell apart, I found bits of it in the header tank. So pull the H/E out , if no ring that would be your problem. I also bought new rubber boots for the ends , the original ones were hard and hard to seal. Tip , The boots thru Volvo dealers were $144 each , I determined that my engine is a Perkins M80T and bought two boots from Parts4Engines for $48. for two ,saved $240. , they were more pliable and fit /sealed well, I also bought the seal from them, like $10. Its important that the seal is placed about 1/4 from the aft end so that it contacts with the opening in the header tank and seals it. With a flashlight look inside the tank ,you will see the opening. So check it out , if you have any questions let me know.

Thanks a lot. That does make it clearer. I will pull out the heat exchanger at the end of the season. I had also heard of people removing the thermostat to force all the cooling water to the heat exchanger and forfait the bypass. The engine is indeed a Perkins 80T Olivier SM Alpha |

Olivier, Removing the thermostat would not change the flow direction of the water and generally just would not be a good idea. The engine would not heat up as quickly,and may not ever rise to the correct temp. ,remember diesel do not like to run cool.Removing the thermostat would not correct your problem, unless you have a bad thermostat,and then it should be replaced ,not removed. Do what you will, but it only takes 15 minutes to remove the heat exchanger and it may just need to be cleaned out,problem solved , if its the seal then order it , problem solved, I would not wait to resolve your issue, but that me.

I'll definitely second what Pat has said here.
Removing the thermostat should only ever VERY short term fix to limp home because the thermostat is stuck closed. Running a diesel without a thermostat will cause serious damage from an operating temperature that is much too low. Removing a thermostat to fix an undiagnosed cause of overheating would be a very dangerous thing to do. Bill Kinney SM160, Harmonie Annapolis, MD. |

Hi Pat this is funny 😀 you remove a Heat Exchanger on a Perkins T 80 or a new Yanmar 110 hp in 15 min. well done spedy concales. I like some texte like that. I don' think you are serious. best regards hanspeter tamango 2 Von meinem iPad gesendet

Hanspeter, I always have a difficult time understanding your posts. I think you are questioning that it takes me about 15 minutes to remove the heat exchanger on my Volvo TMD 22a . If that was your point,( only guessing it was) you are probably right, it probably takes closer to 10 minutes. I only need to loosen three SS clamps and pull the boot off and slide the tube out. I can't speak to how long it takes on a new Yanmar. No need to reply to this reply ,as I won't reply to your next reply,its a slippery slope I've been down before !
