Custom Radiator Project

Postby bertvorgon » 28 Apr 2015 07:23

My spring project this season was to finally get a custom radiator done at Specialty Engineering. As much as the old Monza cross flow has done me well, I thought it was time to upgrade.
With the large oil cooler on one side and my inter-cooler on the other, I just could not drop in an off the shelf item, at least one that would maximize my radiator support opening. There was also the simple issue of maintenance. I have a large oil line fitting that projects out towards the end tank from the bottom of the oil cooler.

Andy decided to put a small taper into the end tanks, and, make a nice cut out for the cooler line, so the radiator goes straight down when installing. He put two threaded pop rivets for the brackets to hold the tank in at the top, and used my existing saddles on the bottom, with a thin rubber cushion.

My old Honda fan was an issue to, so we just decided to put another fan out front. This is a major bonus for me as I can now get at my methanol injection system for any servicing, without major hassle. I had to re-route the two feed lines for my water spray and methanol, dropping them to under the radiator.

Andy also noted my crinked fender eyebrow trim and my bottom stainless grill trim was missing the three mounting tabs....don’t remember why they got removed....! In a few minutes Tracey had some nice used pieces, finishing the front off nicely. The new fans sit further in too, so nothing touches the grill.

Andy found a nice hose with a right angle for the top hose, so it kept it square to the top of the radiator, bottom hose was the stock one.

I changed the oil and did my spring nut and bolt check, getting rid of some rattles inside the car.

On Saturday I drove the car back to my work, dazzled by the acceleration again and truly looking forward to this year's drives.

I'll bet the weight difference is huge.

But the first thing you'll notice on our drives is how fast the aluminum radiator will take the heat out of the system compared to the brass unit.

That core looks very similar to the one I used, did Andy base it on the Ford Aerostar rad core? If not, what was the original application and dimensions of the core or radiator?

I sure noticed how active the temp gauge is now, on the drive back. I could see EXACTLY when the thermostat would open, temp would drop 5 degrees, come back up 10 degrees, then crack again.

When I shut the car off, and left the fans running, the rad was cooled right off, after maybe 5 minutes.

This is going to be so nice for when we get stuck in traffic for any length of time, let alone just better for the engine.

Very nice Mr Vorgon.

The twin fan installation is so simple in its mounting, Andy did a great job forming the mounts to daisy the fans together.

The threaded insert tool if a tool i have been looking at buying for some time. Fabory makes a beautiful insert in steel, but the pneumatic tool in install it is nearly $800. But it's on my wish list for a someday purchase. The threaded inserts sure make a nice installation. The rad will slip down in seconds with easy access to the fasteners. On the Bronze I opted for the top plate to be the securing point, but now I think that what you have done, even with two small fasteners, is a better way and gives more back up. My rad in the Bronze also sits in a saddle at the bottom.

My guess is that, like the Bronze, when you stand at the rear of the car you'll feel the heat right past the rear bumper when the fans kick in. My two fans draw 14 amps at start up, man they do push some serious air, and I suspect yours will as well.

After all these years worrying about the temp getting too high when traffic slows in higher temps, you are going to love the peace of mind moving forward with this set up. Great work Bert, as always.

Very nice installation Keith, solving many niggling problems all at once, and it looks RAD!! (couldn't help myself!)

All kidding aside, it looks very good and sounds like it works like a charm, we need a Specialty down here!

Looks great Keith! Nothing like peace of mind while stuck in i5 traffic or hard charging in the HOT canyons. Aesthetically speaking, the engine compartment looks even moar amazing. You & Andy did an awesome job as pre usual. :mrgreen:
