A Brighter 74 Lamp

74 LED Lamp T1-3/4 Alfa Romeo Alfetta Tachometer

I was having trouble seeing the turn signal indicator in my 1979 Alfa Romeo Sprint Veloce. Though I am relatively old if you’re young, I didn’t want to look that way driving down 101 with my turn signals on.

When the original thermal turn signal flasher gave up, I replaced it with an electronic flasher. With the engine off I can hear it clicking very clearly – I can’t hear it while the engine is running unless the fuse box is open and I stick my head next to it – not a good driving position since the fuse box is just above the floor.

Probably 40 years ago, I made a turn signal amplifier using a 555 integrated circuit and a Mallory Sonalert. It was annoying, sort of like the beepers that some vehicles have when they’re backing up.

I started looking for a brighter lamp for the turn signal indicator that is mounted below the tachometer. The OEM lamp is a 74 Miniature Indicator Lamp – 14 Volt – T1-3/4 Sub Mini Wedge Base. In bright sunlight, it’s difficult to see if the OEM lamp is flashing. I found an LED replacement lamp that is essentially a SMT LED stuck on the end of a plastic tube with a diode and resistor to drop the voltage. It had the necessary wedge base. I had to file the sides down a little so it would fit in the lamp holder, but it was worth the $5.50. It’s bright enough to see in direct sunlight, but not so bright that it’s too annoying at night.

A little over two months ago, an incompetent driver slammed into my parked Alfa Romeo. The Alfetta was in the body shop for 46 days while I argued with State Farm over the value of the car and searched for replacement parts.

I was lucky to find some Euro-bumpers on AlfaBB.com. Larry Jr., at Alfa Parts Exchange was more than helpful in getting me grills and headlight buckets. I was up in Berkeley, so I made a personal appearance at Alfa Parts and bought a reproduction turn signal lens, complete with white gasket. Skip, at J & J Autobody in Monterey, did very nice sheet metal work.

Daniel Stern only had a 5.75 inch Cibie H4 headlamp. I had great difficulty finding a 5.75 inch, flat face, Cibie H1 headlamp. A deep Google search for Cibie “flat face” led me to Joe English, owner of Group2 Motorsports for the H1 headlamp. The last thing I’m waiting for are some Osram SilverStar H1 bulbs I bought on eBay.

In the end, it’s an experience I prefer not to have gone through.

Alfa Romeo Rust Repair

The body shop called today to point out some rust they found when they removed the rear bumper (like I didn’t know about this). I guess what they really wanted to tell me was that it was going to cost more money.

I had ladled POR-15 Rust Preventive Paint on the sheet metal above the left bumper shock six years ago when I saw it looking not so good. I tried to put out of my mind the rust that I could see inside the bumper where the rubber had split.

Mo’ money, mo’ money, mo’ money…

So far the body shop has repaired rust in the front rocker panels, around the base of the windshield on the passenger side (without removing the glass), around the right windshield wiper drive shaft, on the door under the driver’s side window, around the rear bumper shock, below the bottom edge of the rear window and the trailing edge of the trunk lid.

Over the years I had treated those areas with POR-15 and/or Eastwood Rust Encapsulator Paint and that seemed to slow the oxidation down almost completely.

I’d previously done my bush league repair work on the rust on the inner front fender wells and a large hole in the spare tire well – my first attempts at using fiberglass. Those repairs look great if you don’t look at them.

Thanks to my friend Kenny, I have an Alfetta Sprint Veloce.

Thanks to my friend Steve Fields, purveyor of automobilia, I now have the book, Alfa Romeo Alfetta GT by David Owen. Owen is the author of numerous Alfa Romeo books.

Alfa Romeo Alfetta GT covers some of the history of Alfa Romeo, the Alfetta’s family tree, Alfa Romeo racing and the Alfetta GT through the GTV6.

The Alfetta GT chapter outlines the design ideas and engineering solutions to problems such as weight distribution and rear axle design. The result being a clutch-transmission-final drive unit, DeDion rear axle and in-board disc brakes.

I’ve read that Giorgetto Giugiaro‘s original design for the Alfetta GT had retractable headlights, but I’d never seen any images. Owen’s book illustrates that with some of Giugiaro’s original sketches.

For the illiterate crowd, there are eight pages of color photographs plus black and white photographs of Alfettas and its predecessors throughout the book.

Alfetta Cooling Fan

I think because my 1979 Alfetta Sprint Veloce has an air conditioner, engine cooling seems marginal when the ambient temperature is above 80 F (27 C).
When running at speed, the temp gauge indicates a normal 175 F. But when stuck in traffic, though the engine doesn’t overheat, the gauge goes halfway between 175 F and 250 F (79 C to 121 C).

I had the radiator checked at a radiator shop; they said there’s nothing wrong with it. I’ve bled the cooling system at the pump and thermostat and use Red Line Water Wetter in the coolant.

In an effort to help with cooling when the car isn’t moving, I replaced the stock electric fan with a new one. My reasoning was that a fan with a modern design might be more efficient. I bought a Flex-a-lite 390 S-Blade Black 10″ Electric Fan. It’s a 10″ fan that advertises 775 CFM. The space behind the radiator doesn’t allow dual fans or a larger fan. The new fan doesn’t seem to make an difference in cooling.

I also thought about using the new fan to replace the one in front of the A/C condenser but I wasn’t sure I’d be able to remove the old fan without removing the radiator and A/C condensor. I know the old fan won’t come out through the gills below the bumper. I haven’t removed the grills yet. I cleaned a few bugs off the condenser, but even when the A/C fan is on, I can’t feel much air coming through if I put my hand behind the radiator.
