bushytails Posted Sunday at 12:55 PM Share Posted Sunday at 12:55 PM Hrmm, I could have sworn the 2wd still had it, but it's been so long since I've seen one, I seem to be mis-remembering! Link to comment Share on other sites More sharing options...

You're not the only one. I fortunately, didn't spend much time directly under the brats that I owned. If anyone has any spare parts, shoot me a PM.

el_freddo Posted yesterday at 08:41 AM Share Posted yesterday at 08:41 AM Just wait until you get into torsion bar specs. Brumby/brat are heavier than the wagon. And a mob over your way makes new ones that are 30% stiffer from what I’ve heard. Cheers Bennie Link to comment Share on other sites More sharing options...

If you use one, you must install a reservoir like a newer car has. From what I can tell, running them without a reservoir, with an air bubble in the top like these cars normally run with, causes them to instantly crack due to thermal stress as the air bubble moves around. So, what does most people use for the overflows now? Mt. Dew bottle zipped into place? Rather use something that looks somewhat factory. Link to comment Share on other sites More sharing options...

Rather use something that looks somewhat factory. I got a universal stainless steel one on ebay. Google, ebay, or amazon for universal coolant reservoir, universal coolant tank, and searches like that. There's tons of nice-looking ones available.

bushytails Posted 16 hours ago Share Posted 16 hours ago I should add, it's just my *theory* that not having a reservoir makes them crack. I've had a lot of problems with them cracking, and here's what I decided: With no reservoir, the radiator always runs with a bubble on top. Even if you fill it to the brim, when it warms up and expands, it'll push coolant out the cap, and pull air in when it cools. At idle, the bubble is at the top of the radiator. Coolant entering the upper hose at low velocity drops by gravity and slowly flows through the tubes, with the top couple tubes filled with air from the bubble. At throttle, the high-velocity coolant against the resistance of the tubes causes coolant to flow through all the tubes, including the top ones, and the bubble is pushed to the outlet side of the radiator. You can see this if you look down the cap with it running - the level drops when you give it any throttle. So, at throttle, the top tubes are filled with hot coolant, and are hot. As soon as you go to idle, and the bubble moves into them, the airflow over the radiator instantly cools the tubes down to air temperature. Then you give it throttle, and they get filled back with hot coolant, and instantly heat to coolant temperature. Then you go back to idle, and they drain and instantly cool to air temperature. And paper thin aluminum can only take so many 100 degree temperature cycles every few seconds before cracking... especially since when they cool, they contract against the force of the rest of the hot tubes expanding the tanks apart... I couldn't find any other claims about this when I extensively searched for info on them cracking - just lots of other people having mysterious cracks in fairly new expensive radiators. So, with no other competing theories, I'll go with the one I came up with! 1 1 Link to comment Share on other sites More sharing options...

Durania Posted 8 hours ago Author Share Posted 8 hours ago Picked up 5, spoked wagon wheels last night from a guy in Nashville that came off his BringATrailer Brat. Got a great deal as the tires are like new and Kuhmos. Dude even hooked me up with the spare tire retaining screw that I was missing. I was sad to see the retaining plastic rings are discontinued from Subaru. Guess I'm going to have to find someone to 3D print me some. https://www.thingiverse.com/thing:1024984#files Link to comment Share on other sites More sharing options...
azdave Posted 5 hours ago Share Posted 5 hours ago 10 hours ago, bushytails said: I should add, it's just my *theory* that not having a reservoir makes them crack. My problem was a stupid radiator cap and how it fit (improperly) to the filler neck. The cap seemed to fit great when I installed it but unseen by me was the fact that when it was installed, the overflow relief spring was fully compressed and therefore, would not allow excess pressure to vent to the overflow bottle. It was basically a radiator cap with no safety relief whatsoever. I had just installed a new radiator, new cap, new clamps, all new hoses, new thermostat and new temp sensor but had to stay with the original heater core as it was not blocked and working fine until then. Guess which part split open when the coolant pressure was unable to vent? Note: I bought the radiator and cap from the same vendor who showed them as a correct fit but clearly they were wrong. Moral of the story here is to carefully check the fitment of your radiator cap to the filler neck. Half the stuff being sold online these days shows as "compatible" when it isn't and it cost me a heater core repair, which is a nightmare. After that mess, I got one of those radiator cap testers and confirmed that the cap released pressure properly. I also used a caliper to confirm the depth of the sealing ring within the radiator filler neck and compared it to the requirements of the radiator cap.
