1940 Pontiac Horn Repair

The best source of technical information, help, and ideas is always from our hobbyist members themselves. Such is the case of this information on repairing your horn contactor (button) assembly in your early Pontiac. While the example in this article is of a 1940 Pontiac, it is very similar to other earlier years too.

If you have technical advice to share, please help us all be sending it in.

1962-'64 Pontiac Tachometers

One of the most popular options for the early '60s Pontiacs is a tachometer. But, with the different years and models, not to mention types of transmissions, it can get a bit confusing. Here is the information as found in the 1962-'64 Pontiac parts manual.

If anyone can add more information, such as additional year applications, please share it so we can save it and share it with everyone.

It's interesting what you can stumble on snooping around old files and such. Like this May 16, 1968 Pontiac Sales Promotion Bulletin on the new Firebird and GTO Ram Air II 400 engine. In none of our other sources do we find such detailed information, not only of what this RAII consisted of, but also the price, recommendations for use (rainy weather is out!), and even the dealer installation procedures.

Door Panels, Street Wheels & Dash Pads Restored- Where to Go and Who to Call

There are certain areas of restoration that best be left to the professionals. And with that said, there are "professionals" and then there are "PROFESSIONALS!" But how to tell the difference- at least without a very costly bad lesson. That is where finding out an expert's opinion is invaluable.

Here Pontiac Paradise owner Les Kasten has shared his experiences in the reproduction/restoration of Pontiac door panels, steering wheels, and dash pads. If anyone has good quality Pontiac knowledge gained for years of experience, it is Les. And we thank him for sharing this information with us.

DuBonnet Suspension- 1934-36 Pontiac: Part I and II

The earlier years of automotive innovation are filled with items that were thought to be great ideas, but for one reason or another just fizzled out. Such is the case of the DuBonnet suspension system adopted from a French designer and used for only a few years by Pontiac and Chevrolet. In this two part report we have a very detailed account of a member's overhaul of his 1936 Pontiac DuBonnet units, and the actual pages from the 1935-36 Pontiac Maintenance Manual.

Early Steering Systems

If you think cars only got more complicated as time moved on, here is an example of just the opposite... something that was complicated, that got simpler. The early steering systems of our Pontiacs contained a relay rod assembly that contained lots of parts that today there is no longer a need for.

GM Gauges- Tachometers

There is little doubt that Pontiac was the leader in most all things automotive performance related in the mid-1960. So, it is little wonder that when the subject of tachometers comes up, the Pontiac examples stand out from all the rest of the GM herd. This article shows the many different examples and layouts from this period, including some of the other GM gauges as well. If you're looking for what is correct, or looking at something to buy, this may help you make the right choice.

HEI Coil Conversion

Sometimes you find out things that can make your car better and more reliable the hard way... like when your good old (even if new) HEI leaves you sitting somewhere, hopefully not too far from home and a good neighbor with a truck and tow strap. Such was the case with our '40 Pontiac which sports a '74 T/A 400 engine. That lead to investigating ways to perhaps avoid this from happening again. Since heat is an HEI module's number one enemy, we decided to check out the HEI coil conversion... as in eliminating the heat generating distributor mounted coil for a remotely mounted coil- like they did (probably for a good reason) in the old days.

Check out this process and see if it might be something that could help your HEI keep its cool in our On-Line Magazine at: Click Here

Installing Power Rack & Pinion Steering in Your Older Car

There are many things you encounter when building a hot rod/street rod that you never though about having to address before. Installing a new power steering system in your older car is one of them. But, remember, much of the enjoyment of "building" a car is supposed to be the research and planning- also remember, much of the frustration of "building " a car is the same! But, not insurmountable, especially when someone comes along (as here) and gives you all the hard fought information for free. We hope this will help you as you "build" your new old car.

Interior Make-Over: 1969 GTO

One of the scarcest jobs to the average wrench turner is anything that has to do with interiors. Well, it needn't be so scary, nor so difficult when you have the right how-to information and the number of suppliers making so many fine materials for most of the newer Pontiacs.

Here our good Pontiac friend Jim Black walks us through the work on recovering the door and rear side panels of his '69 GTO convertible. As with all of Jim's work, it is extremely detailed and photo documented. And, we thank him for sharing this with all of us.

Knowing Your Pontiac Automatic Transmissions

The advent of the automatic transmission as we pretty much know it today can be attributed to General Motors with the introduction of its Hydra-Matic transmissions; and Pontiac was a big part of this story. While others tried, GM succeeded in bringing durability and reliability to the public, with enough confidence to move from the tried and true manual gear changers to these all new automatics. Here we bring a study of some of the most successful automatic transmissions as used by Pontiac. It will help you understand what was used when and what its pluses and minuses may be.

Loose Timing Chain? How to Chect it Out

Don't get caught with your timing chain on the loose. As many Pontiac hobbyists know, the earlier Pontiac V8s were in the habit of jumping chains right at about 120-125,000 miles. Almost like clock work.

But here is a very simple way to check your timing gears and chain for proper operation/tolerances. Hopefully it will help you from becoming the stranded victim of an old Pontiac with a wayward timing chain.

Mickey Thompson HEMI Heads

The word "hemi" doesn't belong strictly to Chrysler, although they were the only ones to ever move this engineering concept into production cars (with great success too). Here we see some interesting information on what many consider only an "urban myth"... a Pontiac hemi head. However, it took aftermarket developer Mickey Thompson to make this a reality. Even then, it did not take off market-wise, although the heads did power-wise. See an old M/T product sheet with these Pontiac hemi heads, and see information on some rare survivor items.

In this review straight from the '58-'59 manual we see the components and explainations of how it worked... or most often, was "supposed" to work.

Pontiac Flathead Engines: 1933-1954

One of Pontiac's most famous features was its time proven flathead engine design. From the beginning of the flathead straight-8 in 1933, followed by the inclusion of the straight-6 in 1935, it was little changed until it was finally replaced after 1954. As with other manufacturers, its positives had by this time become negatives as others were passing it up with their new OHV V-8s. An era ended.

Pontiac Vacuum Gauges

The '60s saw just about anything and everything one could imagine being marketed to the car buying public if it looked like it had to do with performance. And while many perhaps actually "used" the devices for the intended purpose, many were more than likely just car eye candy. Such was the cool '60s Pontiac vacuum gauge.

Certainly it was one more item to add to the race car look of your daily driver, but if monitored, actually had a purpose- other than "Hey, watch me bury that needle!" Regardless, they are good looking accessories to add to your old Pontiac. But be careful, there is much to look for in purchasing a good, working unit.
