Saturday morning I made a pile of hash browns for the family, cleaned up the kitchen, and ran a bunch of tools out to the garage to get a long-awaited project started: installing a new aluminum radiator.
I’m always conscious of starting projects that I might not be able to finish in a weekend, and this time I was under the added pressure to getting it done by the afternoon, because we had family plans for Sunday. Additionally, I’ve got an appointment next Saturday across town to have the caster correctors installed, so I wanted to have everything road tested and ready. I have anxiety about having a broken-down truck sitting in the driveway with an appointment on the horizon.
First, I drained the coolant. It came out relatively clean, a little milky from age but not black. I got about two and a half gallons out from the stopcock and the lower rad hose into an old cat litter pan. Then I pulled the lower hose and the upper hose, disconnected the shroud mount and pulled that apart into two sections, and loosened the body bolts. Everything came off smoothly; nothing needed PB Blaster (although I used it) to get started, which was a blessing.
Once that was done, the old radiator came out easily. The bottom was getting corroded but it wasn’t as bad as my spare, where the bottom rail is disconnected from the frame.
Then I pulled the new one out of the box and slid it right in place—this time I stood and straddled the fenders to drop it in from the top. Hand-tightening the body bolts, I put new hoses on above and below. The lower hose needed a 2″ trim to avoid a bad kink in the bendy section but other than that they both slid right on. Next I hooked up the overflow tank for the first time since I’ve owned it: the old radiator was missing the brazed nipple on the cap valve. Then I installed and adjusted the shroud mount and shroud itself, tightened the body bolts down, and checked all of the fittings.
The only thing I didn’t have were two blockoff bolts for the automatic transmission inlet/outlet, so I ran around town to find a set and found them at Advance. They’re brass but I wrapped them in Teflon tape and tightened them into place.
Finally, I put about 2 1/2 gallons of new 50/50 antifreeze in the system, topped off the overflow tank (I need a new one, because the plastic mounting brackets have both snapped off), said a prayer, and started her up. I idled in the driveway for 15 minutes, pausing only to cap off the radiator once the bubbles stopped, and let her get up to temperature.
I had to stop at that point for dinner and other family stuff, so Sunday morning I took a 20 minute ride around the neighborhood to shake the hoses around and see how things held up. I chose a route that featured lousy roads (there are no shortage of those) and lights to stop at and some long stretches and banged her around a bit, and I didn’t see any leaks or steam. The temp gauge stayed pegged to the left side of the horizontal bar. Success!
Should I have flushed the system while I had it open? probably. In the fall I’ll have Jiffy Lube do it for me when I get the oil changed. Could I have saved money mixing antifreeze myself? definitely. But I was in a hurry and I had nothing else to mix it in.
Special thanks go to my pop, whose tools I inherited, which made everything much, much easier. Happy Father’s Day, Dad.
Peer Pressure has been running strong and smooth the last couple of weeks; I’ve had her out every weekend since the top came off. She’s hauled bags of dirt and mulch from the store, garbage to the dump, and run multiple errands around town—basically whenever I have an excuse to go out and get something. I’ve been poor at shooting any pictures, because I haven’t ranged far from home, so the sights are all the same. But I’ve got some plans for her in the next couple of weeks, stuff that’s making me excited. The first thing is replacing the old radiator with the new aluminum unit I bought back in March.
This should be a straightforward procedure. I don’t have any extra cooling gear hooked up to what’s there right now (no transmission cooler, although adding one eventually would be a wise move) so it should be a matter of draining the block, pulling the hoses, detaching the shroud and shroud mount, and unbolting it from the body. Hopefully it’ll pull out without any fuss. Next I flush the block with a kit I bought and clean everything out. Then I put the new unit in and bolt everything back into place. Hopefully the shroud I fabricated will install with little fuss; if anything I’ll have to drill two new holes to adjust for the new radiator. I’ve got this coming Saturday blocked off to accomplish this, and I hope it goes smoothly.
Second, I’ve got an appointment with an alignment/front end shop over on the East side of town to put the caster shims in, as well as go over the front end and tell me what’s in need of repair. This will happen in two weeks, and I’m going to wait there while they work on it. Hopefully we won’t need to order out for any parts, but you never know. I have a feeling they’re going to find some bushings and other parts that are worn, and that will almost certainly require new parts. In which case I’ll just Uber home and wait for the work to be done.
With those two things completed I’ll feel much better about a drive out to Ohio for Nationals this year. I’m really hoping the caster shims help out the handling issues, because I miss having a Scout that tracks straight. If things don’t improve dramatically, I’m going to start saving up for some 16″ steel wheels I can mount a skinnier tire on, and I’ll have to take a loss on the wheel/tire combo I’m running right now. But that will come next year.
I took some time to look over the Champion radiator that came in last week and compare it to the stock unit I’ve got out in the garage so that I know what I’m working with. I bought the 3-core deluxe version, figuring cooler is better with a 5.7 liter engine, and also got two new upper and lower radiator hoses to replace the ones that are there.
Overall, it’s a very sturdy radiator and feels solid in my hands, as well as 10 pounds lighter than the OEM version. I pulled my spare fan shroud from the parts bin and test fit it (use M6 x 1.00 x 16 metric bolts) to find that it doesn’t quite line up at the bottom when I started two bolts at the top. I’ve read in some places that it needs to be trimmed to clear the pulley and fan, but I won’t know that until we get into it.
When I line it up side by side with the OEM unit it sits a little shorter in comparison, but I’d need to take more time to measure and compare to see if it’s any deeper.
Look what showed up on my doorstep yesterday!
