Cleaning up the engine compartment on Blue 72

Post by njoconnor » Sun Jul 02, 2017 5:44 pm

Over the last couple of years, we've met one of Madison's original Fiat mechanics (ex-Fiat of Fitchburg) while we showed the 72 at the Botham Vineyard's annual Vintage Celebration. Each of the last three years, he's noticed the annual changes, and gently made suggestions for the next year. Last year, it was direct: "Neil, you really have to clean up that engine compartment, especially the wiring and those cam box covers!" What he saw:

(PS: the air cleaner wasn't THAT rusty; bad lighting or something.... :oops: ).

After a lot of reading on the various forums, planning and sequencing, and some excellent help from Ari K (Merci tres beaucoup, mon ami!) on polishing cam boxes, and from Csaba on hoses and other worries, Patty and I rolled the following out the door this afternoon:

Essentially pulled the various parts out of the compartment, cleaned, degreased, and repainted the compartment walls, and all of the metal brackets, holders, and of course, the radiator. Corralled up the wiring, installed wiper relays (ignition set is in a couple of weeks). New coolant hoses, and the de riguer "T" for burping. Fired up, got to operating temp in good order, and ran beautifully between storm cells this afternoon.

Needs a good cleaning inside and out, and then it's ready for Freakout 2017! See you there!

What did you do to the exhaust manifold? Was that repainted or replaced?

--looking very nice there Neil. Well done!

--You might check to see if you can eliminate the rubbing of the coolant hose that runs from the thermostat "T" to the external thermostat.

Joe: oh, yeah.....car did seem to run better on its shakedown yesterday, and acted a little perkier when going past the local Fiat studio this morning.... :)

Jim: Agreed. Keeping an eye on it for now, but when I find the same blue hose in a non-formed length, I'll probably swap in a slightly longer piece.

Chris: Took off the manifold, wire brushed it, degreased it with citrus cleaner, frog-taped the gasket surfaces, rattle canned Rustoeleum rust inhibiting primer, then top coated it with VHT aluminum color exhaust header paint, two thin coats, drying 24 hrs between coats. I was amazed at how close it looked to the (untouched) intake manifold; I will not claim that was planned. The paint requires curing, either in an oven, or on the car. The oven was a no-go....did not even ask. On the car was straighforward: run for 10 min at op temp; cool for 20 min; run again for 20 min at temp; cool for 20 min; run for 30 min...this was the shakedown run with Patty. Very pleased with the results.

Thanks!
