Always scrutinize your fluid levels on a general grounds for older cars.
As with most other latest automobiles, accurately troubleshooting problems with your 1994 Pontiac Grand Am GE can be ever arduous due to the complexity of engines and electrical components. On the contrary, learning basic automotive mechanics and some of the deeper regular problems other consumers compass experienced with the 1994 Grand Am can be a convenient first step to getting your vehicle on the plan again.
Instructions
1. Research websites such as the Internet Car Counselor or My Van Stats for recalls on the 1994 Grand Am. As of 2011, the Grand Am has two recalls: one for the welding on the fuel cistern meeting and another for the high-reaching now flowing down the ignition switch provided the van won't exit and the leading is held in the inception position for very far-off. Additionally, analysis for TSBs (scientific assistance bulletins) on the Grand Am, which may clue you in on a particular holy mess occurring on your vehicle.
4. Stand behind your 1994 Grand Prix while it is in the Park position and running, looking at any smoke that might be coming out of the tailpipe. If the smoke is excessive and white, then you may have a failed head gasket, allowing coolant to mix with the air-fuel mixture in the cylinders. The Actron CP9150 or the CP9145 (among others) can both be used to recite the diagnostic codes. Gaze up the troubleshoot principle using AutoZone's Repair Counsel for the 1994 Grand Prix. Common problems found through the OBD codes include the EGR (exhaust gas recirculation) system and the ABS front wheel speed sensors.
3. Check and replace the seals and weather stripping around the doors and trunk spaces if they appear aged or dry-rotted. The 1994 Pontiac Grand Am has a reputation for some models leaking water into the interior during heavy rains. If all the seals are in place correctly and the vehicle is still leaking water, check behind exterior lighting fixtures for possible leaks. Use silicone to caulk the seals around the lights for extra weatherproofing.
2. Establish the OBD (on board diagnostics) terminal on your Pontiac Grand Prix, which is located in the passenger compartment underneath the dashboard. The terminal is a 16-pin connector that looks consubstantial to the OBD II connector. Nevertheless, the 1994 Grand Prix de facto uses what some touch to as OBD 1.5 and requires a particular scanner to interface with the OBD II terminal and using an OBD I translator. Additionally, you will notice lower coolant levels in your overflow reservoir. A leaking head gasket is also dangerous to your engine as it also allows coolant to mix with oil, which could cause permanent engine failure. Blue smoke is an indication of oil leaks around the cylinder heads, which can be fixed by using thicker oil or an additive. Black smoke is a sign that your fuel-mixture is too rich, possibly caused by faulty fuel injectors or fuel pump.
