BUGaru Part 10 - Cooling System

[@goodguy555]

Can't wait to hear it run!

+RandomGuy Soon!

Sounds awesome!! Stopped by and saw this amazing bug!

[@KUTZFRECH]

Bursaries!!! I can't thank you enough for taking the time to make these videos you have helped me tremendously with my diy project however I need some help... I'm a little confused with how to route the heater tubes do I connect them together with a u style piece of tubing? I have a non turbo motor those heater tubes are confusing me

[@Busaru]

+KUTZFRECH If you're not installing a heater now then just "U" them together.

[@KUTZFRECH]

Thank you so much for your response I religiously watch your. Ideas back to back to back you have no idea how much you have helped and not to mention make this dream come true as corny as it sounds lol... I have the heater thing under control that was easy I was overthinking it lol... the next thing that has me stumped is the radiator... I'm not understanding how to setup up the fill tank reservoir and or overflow isn't the overflow supposed to be upfront? I'm using a scirocco radiator

[@kevinhornbuckle]

The aluminum tubing will help dissipate heat. Don't let the tubing touch steel anywhere. Isolator bushings are easy to make with old inner tubes or vinyl pan liner from the tile section of home improvement stores. What did you use to make the bends?

[@forthwithtx5852]

Yes, I was wondering if you bent the tubing yourself or if it was an aftermarket item..

[@Busaru]

+Kevin Hornbuckle Thanks for the tips on isolating the aluminum. I used a standard EMT conduit bender - cheap and works great for this sort of thing.

[@Busaru]

+Forthwith Tx DIY my friend, simple to bend with a hand conduit bender.

Do you think the height of that arch of tube in the wheel well will be a high point to trap air?

[@Busaru]

+draggonhedd YEP! Any higher point is going to trap air, including the top hose of the radiator and the arch. I'm going to need some revs to push it through. Or putt some bleeders in - we'll see!

[@draggonhedd]

best of luck. Have you also thought about using waterless coolant so the system doesn't need to be under pressure?

[@Busaru]

+draggonhedd A friend just told me about this the other day - I'm excited to research it more.

[@draggonhedd]

itls cool, buy it once kind of thing. Once you have it, you never need to replace it. Need to work on the cooling system? drain it into a bottle and fill it right back up when you're done. Never freezes, never boils, no pressure.

[@Busaru]

+draggonhedd That's pretty incredible that is doesn't pressurize. That could be a great upgrade. I'll have to look into it.

[@mylittlehamburger]

Near the end, could you tell us how much you spent on the conversion? Most of the time when I see Subaru swaps, it's something crazy and expensive. I'm looking for a little more reliability with my 72bug daily driver, so this build you're doing is perfect.

[@Busaru]

+daniel Jimenez That's a great idea, I'll do a video on that subject at the end. This is definitely a lower budget build (reusing a lot of parts from donor cars, etc). Since this is my personal project I tend to keep things pretty budget friendly :)

[@mylittlehamburger]

+Busaru. Thank you!

[@christianschilling9500]

Nice Build so far. Where you got the Aluminum Tubing? Green from VA Christian

[@Busaru]

+Christian Schilling I actually picked it up from the local Habitat Home Store for $10. It was hard to pass up a deal like that.

[@beauvansickle1777]

Curious about how you plumbed the fuel system. Will that be coming up in a future video? That is one of the parts hanging me up in my build. A lot of guys recommend a sump in the tank to avoid fuel starvation, but usually that means a custom tank. Curious about your solution.

[@Busaru]

+Beau Van Sickle (Dirtkatt Motorsport) I would run a sump if you're doing a lot of autocross or rally. I don't plan to compete with my bug so I didn't go with a sump. The fuel video might be released tonight. Cheers!

[@randylucas7751]

i did one of those senders that go in your coolant line not sure if its the best thing but i feel it will work i wasnt sure if my fan would kick on if i replaced the stock one?

[@Busaru]

+Randy Lucas The sender is just for the dash gauge. The Subaru ecu uses a temp sensor in the coolant manifold on the engine to control the fans.

[@jeffinillinois]

What clamps are you using to hold the tubing to the pan/ body?

[@Busaru]

+jeffinillinois they are just EMT one-hole conduit clamps from Home Depot. Inexpensive and effective. May need to isolate them from the aluminum but this is all experimental for me.
