I'm all too familiar with this exact radiator design, replaced one last fall, from the W126 chassis, and that overflow tube coming off the neck of the radiator...that thing is ULTRA fragile. I mean, don't look at it too hard or for too long, fragile.

Because said radiator doesn't have a cap, this is the only way to add coolant to the system.

I hope has the name Nissen, or something besides just the Mercedes star. If that one is OEM, it's already on borrowed time.

You might want to bring a combo of the correctly-sized machine threaded bolt to fit the hole, teflon tape, and JB Weld Qwik to plug it, should it crack.

Alternatively, find an extra rad...or 15 heater cores and a slew of hose.

I saw the puller. Much too far from the radiator IMO. It probably didn't do much but recirculate hot air. Oh well,too late now. Perhaps next time.

And as for shearing the distributor drive pin, it's likely that the pump sucked up a bit of trash which stopped the pump rotors. Those gerotor pumps are not forgiving of debris. With a SBF the debris is usually hardened valve stem seal bits, although I have seen a few valve cover gasket spacers get sucked up. If you don't find what it was the problem WILL happen again

An electric pump would definitely help with water flow, as the stock pump was never intended to push the coolant that far (both uphill and away.)

Good luck at the races!

@cq: Considering the most the truck has done is idle, don't know. Haven't driven it yet, and haven't gotten back on getting the shroud in. We'd be on the electric plan if we had a sheet metal break.

But as far as the sitting in the driveway and running, it's been cooling fine. But, then again, it's got a massive aluminum radiator.

No, the well-vented rear seat space is for the ice chest of beer. Call it a driver negative thermal device.

Good luck men. You are our only hope.

My dad was telling me how damn crazy some aspects can get with custom cooling systems a few weekends ago. Many years back he went to a seminar or something, when he was building up the badass '74 Camaro. Going through the same guess-and-hope-it-works stages with a 70s C10 shroud on my '69.

How much did the radiator cost? If by any chance a bigger one is needed for the next race... I've got a huge aluminum one from a last generation Escalade. Just has water spots from an acid wash... Dealership Freebies FTW. Didn't fit in my truck, so it's just sitting.

We went through agonizing debates that covered every overheating cause mentioned here, plus a few more, and if we'd had another week we'd have worked the bugs out... but we didn't have another week.

I'd like to point out that this is possibly the most hardcore comment posted on Jalopnik, and you bastards ignored it.

First of all, it looks Viking. Secondly, I think I see bloodlust in there, then he says he'll sacrifice some animals for you.

In my experience, you should have had WAY more heat transfer than necessary out of those long tubes, and with that many fans. Unless they were picking up heat from the exhaust?

Maybe it wasn't working because of cavitation in the lines... or maybe the cooling airflow isn't right at speed due to some kind of aerodynamic weirdness you'd need a wind tunnel to sort out... or maybe something we'd never figure out. Regardless, the car had to be ready to go.

That said, the front radiator setup is pretty well protected; the Volvo front bumper is a monster, we've got the crash bars in front of the radiator, and the front edge of the hood is just hanging there, so it's unlikely to get mashed into the radiator top tank.

Murilee Martin

Simple, buy two or three and change them out.

Or plumb them all in parallel with diverter valves and simply switch pumps.

For The Tunachuckers, we reinforce with bits of old lawn tractors and scrap metal found in the barn.

The rear radiator, however, is genius, at least in concept. With adequate time, and an extra few dollars in the budget, it could probably work very well.

Loved that rear rad. I hope the 302 doesn't Grenad(a) on you again this weekend. Unfortunately, I will be at a wedding in CT this w/e, but I'll be sure to catch your zany (mis)adventures Monday.

You should build a cowl induction hood to cover the radiator. It would have to have a low spot in the middle for that crazy air intake, but if you did some kind of wild v-shaped cowl induction hood it would look awesome.

You could have probably just added an electric water pump via Harbor Freight.

[www.harborfreight.com]

from there you simply gut the stock pump and thermostat and use a rheostat or (an electric motor controller of some sort, say like an electric R/C car controller)

Either way, great recovery, hope to hear of your success at Altamont this weekend!

Good job getting it put back together, though. Sucks to have to pull an engine to do an oil pump swap. I did mine (on a Ford 390) with a floor jack and some 2x4's, while the car was up on jack stands. (wiggle that oil pan out!)

Mr. Gasket Street Scoop. Fiero wing. MR2 side vent. That is quite possibly the coolest hodgepodge of a Volvo ever.

I'm not sold on the radiator relief cut through the hood, but I suppose if a projectile were threatening that particular vulnerability, you'd have bigger concerns than the radiator. Like something large and heavy flying at your face/windshield.

Thanks for the update, Murilee.

No, I have nothing of substance to add.
