17 year old car, Pt 1, Electrical/tune up
Well that 2001 Bullit is now 17 years old. It's time for a bumper to bumper check-up. We're going to start under the hood. I will tell you why I do things in the following order as I move along.
1 Electrical: If you're electrical system isn't up to scratch, no point checking any further, deal with it.
Battery: (Voltmeter) Check the voltage after the battery has been charged, should be 12.6-13.0 volts at rest. If less charge again re-check, if voltage is under 12.5v, get a new battery, it's not going to get any better.
Start the car, check voltage, should be around 14.0v at fast idle, if less than 13v, you've maybe got a bad diode or your regulator is wonky. To confirm, turn everything electrical on, lights, fan ac, rear window defrost, radio, full load.If voltage is not holding around 13.5v @ 2000 rpm, it's time to get your battery and alternator load tested.
Pop the covers off your fuse boxes, check for corrosion, visual all your wiring. Have the rodents been snacking?
Check wiring in the trunk. Cycle all electrical units: Headlights, T signals, Brake Lts, check gauges, AC output, fans etc. OK lets move on.
Tune-up: If the mechanicals in your engine are worn, there's no point doing a tune-up. First, after 17 years your car deserves a compression test. You will have to remove spark plugs and coils and follow the directions in service manual. If you find oil in the spark plug holes you may need new valve cover gaskets. (a bit of a job) All cylinders should be within 10%. Example highest 100psi, lowest 90 psi. Manual will tell you the normal range. If all is well, good time to change plugs and check all the coils for cracks and put dialectric compound on the boots. Button everything back up. Start er up. OK, next. Check air filter, change if dirty or clean as required if reusable. Check all vacuum hoses, replace if cracked. Check all intake hoses,remove intake snorkel.
Check throttle body, clean if nec. (Do not use corrosive cleaners, check manual) Re-assemble. Start, Check, OK.
Visual check for any oil or fluid leaks and make note for next section.
Next time: Cooling system, fluids, and lube service. "Hey we're just getting started here." (Al Pacino)
Did I miss anything so far? This is internet Socratic method, impress the Prof, by suggesting what I need to include.

In my defense, I was left unsupervised.
