a bloody good idea, most boat owners know how engines work, and are generally up to do the basics, but are put off when the engine is in a boat, the raw water principle over radiators normally confuse, well done
Hello Parker, I have a question that I would like to hear if you can answer for me. I have to remove the diesel injector pump on a Volvo Tamd 41b, year 1990. When I dismantle this pump, does the cam wheel / pulley need to be fixed? I have seen that a Timing Tool Kit for Landrover is avible. Is there anything similar for Volvo? Or how do you do it? Best regards Ben.
@parkerAdams, Well done! So I would like to ask you, wether you have experience about electric engine preheaters? How to install, required power 500W, 750W or 1000W ?
The blades of original impeller were downward facing, indicating a clockwise rotation of the impeller. The replacement blades were facing Upwards indicating a counter clockwise rotation. Will the blades reset to proper clockwise rotation once engine running & water pumping?
Hi I noticed this also, however the impeller turns anti-clockwise or the long way round from inlet side to engine side. The impellers push the water around rather than pull the water around, imagine emptying a bucket of water with your hand. The blades or vanes will correct after 1 revolution. Hope this helps 😀
This impeller was fitted incorrectly, at 0:34 to 0:46 you can clearly see the impeller is set to rotate in a clockwise direction, pushing the cold water up into the filter above. At 4:14 the impeller blades are facing the opposite direction to the rotation of the drive shaft. Hopefully on startup the blades will correct themselves without causing damage to the impeller.
@@brucestrachan3368 sorry I missed your message a while ago, a few people have commented about the blades on the impeller now, in fact the impeller blades were the wrong way round before as it has had works done, hence why the engine is out and at some point the engine was rotated the wrong way by hand. I have explained in the video the correct rotation and fitted it in the correct way.

I see in the video that the impeller blades are installed the opposite way. So does this have an impact or do the blades rearrange themselves after 1 turn of the impeller?
They 'should' rearrange themselves. I would have twisted the impeller the other way, against the cam, so there is no doubt they are going the correct way. Once the cover plate's back on you'll never know if it's all good!!!
The impeller you took out the impeller blades were leaning left or counter clock wise but the one you installed the blades were leaning to the right or clock wise. Why????
Hi Parker, thanks for the vid. There would have been a thin gasket that came with the new impeller. Can you tell why you never used it? In your opnion is it not needed?
Hi there, this type of impeller cover has a rubber oring seal, as shown in the video. This replaced most earlier pump housings which require the paper gasket instead. In the new impeller kit you usually get both types as the same impeller will fit in both pump types. Hope this helps, I will be putting more videos on so please subscribe to our channel.
@@markadams2723 if it is sea water you are losing a common place is the impeller pump shaft seal, there is a gap at the back of the pump to allow water to escape there if the shaft seal is worn as otherwise it would go into the engine.
First note which way the blades go and fit the same way around ! Put a tye rap around new impeller to ease fiting , and you call yourself a professional! I think not!

You do not need a tie wrap in most cases but on occasion it can help on the larger impellers so thank you for that.

Nice job 👌
Great tutorials. I am a bit of a diesel novice so happy to see some pro tips. How about decompression usage, changing belts and anodes?
Is this impeller use in the engine cooling water pump?

hi Parker, useful video. Do you have any hint for the heat exchanger cleaning?

@@brucestrachan3368 Yes they should rearrange themselves but in very rare cases they don't. I had a overheating problem because of that.

Because he fitted it incorrectly

@@ParkerAdams Great thanks!
Should both be used? What about the small black disc for the end of the shaft?
Oh ffs. I need another tool to get the impellor out just to inspect it? Argh....
My Volvo AP 41 6 cylinder is losing water could it be this

It’s the fresh water I put into the header tank sorry to sound stupid but I’m just lost with all of this
can you share dimensions of o-ring?
Udskiftning af termostat
Don’t want to carry special tools for every task on a boat. Would have been interesting to see how to remove impeller without the tool.
