AAC Ultimate Cooling Package for a VW Engine!

The heat is on, and its not even summer yet! We're about to leave for another BusBash and I want to make sure the engine stays super cool, so I'm installing another of Andrigs fancy gizmos. These are fixed cooling flaps that direct the air to exactly the right spots for maximum cooling. With the super fan and all the work we did to the tins we should be able to handle the heat with no problems!

You’re not boring anybody by doing everything and showing us how as long as you’re doing it right which looks very good

[@andrigtmiller]

Good luck on the trip, and can't wait to hear about it.

[@OldVolksTV]

The national forest was closed so we had to postpone it .

[@VWJawbreaker]

Can’t wait to hear the results of the upgrades. Great stuff dude.

[@OldVolksTV]

Thanks! Motor should be going in today or tomorrow, then we can see how it does.

[@gmd1417]

@@OldVolksTV Did these upgrades make the engine run cooler?

[@charleslawrence7194]

Good stuff. I'm anxious to see how everything works on the trip. Always enjoy your videos. Keep your body cool. Also looking forward to new t shirts. I wear my blue one everywhere.

[@tetra4411]

I have a Baja Bug. I mounted a 10” fan over the fan shroud, blowing fresh air into the fan intake and over the generator/ alternator. Cooling it down and providing plenty of un-preheated air to the engine. This has worked well for the long desert hwy drives and long hill climbs hwy.

[@OldVolksTV]

That's not a bad idea for a Baja! I've seen people do that with a small oil cooler, and that's bad news. But just a fan seems like it would help!

Nice video. Denison from Brazil.

[@Steve-ff7xj]

Really like the new tech cooling mods, should have used button head allen screws for the louver inserts makes for a nicer look

[@vanzelstrestorations998]

Those little ducts were factory fitted for a reason and many have been left off over time. They should be on every aircooled motor. These are a separate thing to the moveable thermostat flaps.

[@michaelnagy4603]

Very interesting ❤

[@luisrivera3056]

Those are turning vanes, used in airconditioning ductwork to eliminate turbulence.

[@Mikefngarage]

That fan replicates the Corvair fan I think. IDK if the flaps are really going to do anything only if you have an original fan shroud with all the air directors in there. Probably would have made up a water vapor injector with compressor tank and nozzles around the fan intake. I may do that for my truck.

[@OldVolksTV]

The shroud is actually a German one, but it's had lots of welding and bondo. The flaps reduce the "swirl" of the air so it moves past the fins easier.

[@brianchisnell1548]

Stock is rock

[@johnj2496]

Nice You could ditch the bolts for pop rivets

[@tetra4411]

Another mod I found works for me. I blew a valve cover cork gasket on a hot desert hwy. The engine needed to breath.. So I removed the oil filler cap and with a hose clamp and N-95 mask 😷 covered the oil fill hole. This gave a lot of extra heat breathing for the engine. Since then The engine runs cooler and I have not blown valve gaskets.

[@OldVolksTV]

Interesting. I wouldn't recommend too many miles with that cap off, even with the mask. Vented valve covers are easy enough to find or even make. That way you keep all the dust out of the oil.

[@Mikefngarage]

good road fix. breather kit would be the best answer. you need one if you have a bigger engine and driving it a bit faster on the freeway. all those RPM build up crank case pressure. Also best to redo the gearing on the car or bus. so the engine is not revving so high this will stop those things from happening. too.

[@branchsnapper2228]

Cool

Love the videos, I always learn something when I tune in!! That is a really cool fan, looks like it will move a ton of air! Do you think it would work in a stock shroud? Thanks for sharing

[@andrigtmiller]

It fits any Doghouse fan shroud (introduced in '71). OEM, and all the aftermarket ones.

[@patrickmcneil2911]

Cool, thanks

[@ardegaragem7283]

Hi, This turbine that appears in the video is better than the other original model?

[@jeffreybeman5806]

back in the day... 1978 ...the spring would bust and the flames would close and over heat the motors..bug ranch Norco ca

[@michaelbrind9222]

most aftermarket shrouds are crap, VW knew what they were doing when they disigned it, and most of the crucial parts are left out including the thermostat, flaps, and proper direction vanes . and heat exchanger and decent seals on tinwork that isnt chrome tat.

[@mikehammer4546]

Cool video, where and how are you measuring the temp.

[@OldVolksTV]

I'll have an oil temp sensor at the stock pressure location and a head temp sensor on #3.

[@crackpotts5347]

Fellas, I got to see these in person. If you don't have the stock flaps, you must have something to direct the air. I can't possibly explain the effects of not having, over having, but, it has to do with the Lumiere effect. Wind is chaotic and must be directed to be effective. Directed air has a large amount of force when focused, however, once it leaves the machine, it only has a small amount of focus but looses an enormous amount of energy. I can imagine that there are a lot of small eddies inside the shroud next to the inner and outer surfaces of the fan shroud which causes loss of energy. Bla bla bla, directed to be effective!

[@OldVolksTV]

Professor Tony!

[@andrigtmiller]

I have done tons of testing of the fan and fan shrouds, and what is interesting is how the fan itself actually causes the air to swirl inside the shroud. The air directional vanes in the shroud are complex, and what you see is that the 3/4 cylinder side has a lot of vanes in it to direct the air to that side, where there are only a couple on the 1/2 side, and that is because the swirl of the air is in the direction the fan turns, so the air wants to mostly exit on the 1/2 cylinder side. That's why I chuckle a bit whenever I see those center mount fan shrouds with no air directional vanes. They certainly won't cool both sides of the engine properly.

[@crackpotts5347]

@Andrig I absolutely believe you.

[@christophersustayta5974]

So how well does it cool and how much was your fan upgrade ?

[@OldVolksTV]

Less than $200 in parts. It works extremely well!

[@mathewboyd3746]

Where did you find the fixed flaps? I have never seen them. Are you using CHT for temp reading?

[@OldVolksTV]

Andrigsaircooledtechnology.com has the fan, flaps, and several other upgrades. I'm using a laser to read the temps on various parts of the engine.

[@user-zd3zi6lk2x]

I am interested in that crazy cooling fan ! Where do you get them ? Thank you

[@OldVolksTV]

They're no longer available. They were made by Andrigsaircooledtechnology.com , but they have a newer version that is far better.

[@user-zd3zi6lk2x]

Hey thanks for the super fast reply , really appreciate you ! I have 3 cases in my garage and am planning a 1600 "grocery getter" but not "stock " counterweighted Crank , HP rods , 110 cam . Always full flow case . I even throw in a "windage tray" to keep that pesky oil in the bottom of the case . My other build will probably be another 1835 like I built for my 1971 van , 100mph in a straight line , "freeway flier" cornering not so much 😂 Keep on bugging !!

[@ronjones977]

Hey brother did that stuff actually work? It looks really cool

[@OldVolksTV]

@ronjones977 it did. Engine temps dropped drastically. I hvent tried the newest version yet, but I hear it's much better.

[@ronjones977]

@@OldVolksTV that's awesome bro thanks for getting back to me man I really appreciate it I love the videos

[@alexguerrero3675]

Update on the fan please how is it working? I'm really interested in one for my 2180

[@OldVolksTV]

I just got back from a trip. 3 hours of hiway driving, fully loaded for camping and pulling a camp trailer, with 85° temps. The head tin over #3 was 165° and the block was 180° . The fan makes some noise but it quiets down while cruising around 55mph. Overall I'm very happy. From what I hear he's making a new version that looks like a stock fan and is even more efficient. Worth every penny.

[@Rockettube1]

Did you ever get one Alex? I'm interested as well.

[@andgate2000]

Always wondered how the stock design fans coped with a 2275 turbo....i guess it wont.

[@OldVolksTV]

A stock fan will work fine. If you get the RPMS too high they'll slip and cool less, and if you use a tensioner on the belt it won't slip. If it doesn't slip, it'll fly apart. That's why Berg started welding them. If you use a tensioner AND turn high RPMs you absolutely MUST run a welded fan. Or one of Andrigs fans, since they're lightweight and one piece they Han take the abuse.

[@torisings9058]

That fan has been out of stock for a while now. Anyone have any info on a possible eta. I signed up on andrigs site for notification when it becomes available. But I’ve been waiting to make some repairs on my shroud, in hopes that I can swap the fan at that time.

[@OldVolksTV]

I think he changed the design and has taken this style out of production. He has a new version that is closer to a stock style fan with upgrades and those are in production now. Should be available on the website soon.

[@AnzaValley]

Just put a Mazda RX 7 oil cooler on it and it will run cool even at Johnson Valley in August.

[@OldVolksTV]

Is that a thing? I've never heard of that. Sounds interesting.

[@skytopshop]

Where can I purchase the flaps and the fan? I don’t see them on the link you shared.

[@OldVolksTV]

I believe he sold out of those fans. He's moving into a larger shop and should start production soon.

[@gmd1417]

DID THESE UPGRADES MAKE THE ENGINE RUN COOLER?

[@OldVolksTV]

Very much so. In fact, over the winter I noticed my engine wasn't getting all the way up to operating temps, so that's something to keep an eye on.

Looks good but are you not aware that a type 4 or later type 2 or a 914-4 oil cooler will fit the Dog house fan shroud if you widen the Dog house by 1" and that cooler is by itself good for a 2000cc 914 Porsche!

Well, that's 17 minutes of my life I'm not getting back.

[@75vw]

So it’s been a year! What are the results!?

[@OldVolksTV]

Undecided. The motor all of this went on had trouble keeping the heads tight. When I had it running I noticed a significant drop in engine temps. Didn't quite make it to the summer heat. I'm running a 1904 now but it has a welded stock fan. I'm planning to move this cooling to the new motor soon to see what happens.

[@soggz4246]

Why couldn’t you just use the originals and a thermostat? Really would like to know. All the best.👍🏾🇬🇧

[@OldVolksTV]

This setup is more efficient and lighter weight. In Texas we rarely have to worry about cold weather, our motors almost start iff warmed up 😂. The fixed flaps help direct the cooling air to the parts that need it most, which is better than the nothing that was in there.

[@soggz4246]

@@OldVolksTV I guess you just rebuild them, when they do wear out, flaps or not. So you normally just ditch the flaps, anyway, then? As you say the engine is already warm…

[@OldVolksTV]

I believe he's back up and running. He moved into a new house with a bigger shop and he's building up his stock.

[@jameshorel1938]

I don't believe those flaps do anything. The same amount of air is going through the same space. The fan looks cool though.

[@OldVolksTV]

It's hard to see on the video, but the "flaps" are bent slightly to direct the air in the right direction. They do the same thing as the stock flaps

[@andrigtmiller]

The flaps direct the air. The air flow coming down from is actually swirling somewhat, so that final flaps makes sure the air is directed where it does the most good. This was documented by Gene Berg many years ago with the thermostatically controlled flaps that came from VW. A lot of people get the used flaps, and either wire them open, or spot weld them so they stay open, but the original flaps are getting hard to come by.

[@Wiencourager]

Why fixed flaps? You’d be overcooling the engine some of the time.

[@OldVolksTV]

It's almost always hot in Texas so it works out OK. I did have an issue when it was super cold, my engine barely got up to temp.
