Volvo Penta KAD Intercooler / aftercooler demystified

Many great video's on how to clean the intercooler or aftercooler on youtube, however there are no video's showing how the intercooler is mounted / disassamled / assambled, so thought I could turn the lights on and show you quickly how it is build and what it does.
This Intercooler is found in KAD41, KAD42, KAD43, KAD44 and KAD300 (or in KAMD)
Hope you find this useful, DON'T FORGET TO COMMENT OR LIKE

Extremely good film! Good explained! please do more of this content

[@sorenfleron]

Thank you very much :-) I will do more when I find more relevant stuff to record :-)

Thank you very much :-)

If you cant get the intercooler itself out without unbolting the whole casing, then the workshop vacuum is a quick way to enable a descale. Neat idea ! Ok, you cant get to the cooling fins., but...

[@sorenfleron]

Hi - is that because there is not enough space? the insert itself should be fairly easy to pull out using a set of pliers.

[@gavinmay4047]

@@sorenfleron Yes, starboard is ok, but there isn't enough height on the port side

[@sorenfleron]

@@gavinmay4047 Bummer 😞 that is really sad, so empty usinca vacuum and then I guess the only way is to unbolt the whole case. when the case is empty from water you can remove it nicely - there is a good video on this (except for draining 🙂): kzbin.info/www/bejne/rHLChmNme9iar5Y

What if you live in a very cold weather climate?

[@sorenfleron]

Hi @user... I would still clean the intercooler, if it is clogged your engine will have a hard time getting enough air. You also have the compressor to help the engine get more air when running cold. Not sure if that answers your question? BR Soren

[@davidshepherd7750]

Except the shop manual on my -42 specifically points out the drain plug on the intercooler as one point of drainage for winterization.

[@sorenfleron]

Hi David You are absolutely right. The point of this video is that it is not needed to drain there... much easier using a water vacuum cleaner and empty through the hoses :-) Wish you a great day. BR Soren

[@davidshepherd7750]

@@sorenfleron Are you sure you're getting all the water out by vacuuming from the top?

[@sorenfleron]

@@davidshepherd7750 Hi David. Yes that is also what the video is showing. when dismounting the tube from waterpump and sucking on the out of the intercooler the intercooler is emptied out. I was able to suck it, and then remove it from it's cage and it was all emptied out. Really good thing by removing it completely is to clean out all the stuff that is sucked in from raw water. But yes - it was dry. BR Soren

hello greetings I would like to get the workshop manual for volvo Penta KAD 42 KOMPRESSOR

[@sorenfleron]

Hey - thanks for writing - yes would in deed be good, however there is really not much about the supercharger / kompressor, seems to be ONE part, only info is on changing oil in the kompressor which is a VERY good idea to do yearly, and also fairly simple and not expensive...

[@sorenfleron]

Please also see here, there are not many parts around the kompressor: marinepartseurope.com/en/dealer/jlmarine/category/marine%20diesel%20engines/product/kad44p/explodedview/54168140?catalog=7738870_MD4B&functiongroup=Inlet%20and%20Exhaust%20System&img=45444.png&header=Compressor%20and%20Belt%20Protection

I recently had a leak with the aftercooler which resulted in water getting into the engine

[@sorenfleron]

OH NO 😞 so sad to hear. so the aftercooler leaked - do you know why? it does not rust, so strange. Did it damage the engine? BR Soren

[@robertsandall9493]

I think so, waiting to find out. Costly

[@sorenfleron]

Ouch - so sorry to hear 😞how did you find out? white smoke?

[@robertsandall9493]

@@sorenfleron checking the aftercooler we pulled it out and found that it had deteriorated. Also salt crystals in the bottom of the casing.

[@sorenfleron]

@@robertsandall9493 not great - I hope you did not get too much salt water in the engine. Crossing fingers for you. But keep us updated.
