Pontiac Trans Am

5w-30 was factory install. I there more than 100,000 miles on the motor you may want to use a 10w-40 oil or maybe a 20w-50. 10w-40 is a safe option. For the BEST lubrication use Amsoil 100% synthetic motor oil & oil filter. This is fact not opinion.

disconect battery replace item that the SES is telling u to replace use an OBDII tool and reset that way

This varies with model year.

You picked an extremely difficult one.......It would be best to get a Chilton's or Haynes for this. I will tell you that it requires pulling the passenger side fender and inner fender well to gain access to it. Some of the later models....such as your '79 have an impression in the fender well that you can cut and bend down to gain access. When done, you bend it back up and seal it.

You should start by visiting the pontiac trans am site. Where you can find genuine parts. And even upgraded parts. You can also check your local auto parts store.

inter change able parts are those whos parts can be changed.

While pulling the release latch, try pounding on the top of the hood once or twice to break it loose. Those hoods have a tendency to stick sometimes. If you're not comfortable with pounding on your hood, try pressing down on it a couple of times with the palms of your hand at the front before pulling the release latch.

The Trans Am was the performance version of the Firebird.

Please be aware that for 1979 - 1981 Pontiac Firebird/Trans Am models no unique service manuals were created. Instead, model year-specific supplement manuals were printed, which detailed new data specific to their respective model years.

In other words, because the shift knob assemblies from 1979 - 1981 models were no different from the 1978 model year, the 1979 supplement manual refers the user to the 1978 service manual.

This is why the "7B-21_pic" service manual image says it's from the "1978 PONTIAC SERVICE MANUAL".

It is on the accessory sticker. Call your delaer parts store. They can also get it by your VIN ## (have it ready).

325 FACTORY RATED HP.

THE ABOVE IS INCORRECT

Factory claims 93-95 is 275rwhp 96-97 is 285rwhp

Those numbers are crank hp. RWHP would be about 240-250 for an auto and 240-260 for a stick.....

Follow the upper radiator hose back to the engine. There will be a outlet mount there that the hose connects too. There are two bolts on each side you must remove, it may also have a bracket mounted to it as well that will need to be removed. lift the outlet off the engine and you will see the thermostat. lift the thermostat out clean the mating surfaces, install new thermostat ( make sure it is in the grove flat )and gasket, remount outlet housing. Put the rest back together.

Premium (91) is recommended

I have an 87 TPI Trans AM 305 engine. I still have the factory emission sticker under the hood. It says the timing should be set at 6 degrees BTDC. I've been testing at different settings. It would seem that the engine would prefer 4 degrees for more top end power. And, 8-10 for more low end torque. Remember, when setting timing, the higher advance = less top end but more torque. And the more retarded is exactly the opposite. So try to find a balance.

The hook spanners are designed for use with SKF KM nuts as well as any other KM nuts conforming to the DIN 981 standard. Additionally, they are suitable for use with N, AN, KMK, KMFE and KMT as well as nuts manufactured according to the DIN 1804 standard.
