If I do this now there wouldn't be the chance of the pcm overcharging my battery or undercharging if it went out. That is preventing problems. Therefore it's preventive

 

But, there is no guarantee that the regulator you put in place of the current regulator in the PCM (that is still working....) won't do the same thing.

If it ain't broke, don't fix it.

 

I'll order it but wait till it goes out to put it in

 

That's preventive purchasing. : )

 

Which could be a smart move... how many more years do we have before parts certain aren't available.

 

Exactly, the more rare the more expensive

 

Preventative maintenance works for mechanical parts that are nearing the end of their life-cycle: tie-rod ends, ball joints, shocks, rotors, O2 sensors, water pumps, spark plugs and plug wires, belts, and the like. Items like the water pump will present signs that failure is imminent. Most electrical parts should only be replaced *when they fail*. The reason O2 sensors and spark plug wires are included in the life-cycle list is because they degrade over time. The sensor portion is covered with a special coating. The manufacturers recommend those sensors be replaced ~50-65K miles for optimal performance of the emissions system. As some of the folks here have pointed out, don't replace certain parts "just because". Keep a manual and service book to use as a guide and you won't go wrong.

 

Since work has decided to not pay me for anything I've done for three weeks, I still haven't been able to do anything to my truck really, my alternator put out 3 amps on the tester. I was working so I didn't get to witness it tested so I'm gonna take it back and have them test it again where I can witness.

But in the three weekz I've been working I've made 60 bucks that's doing a whole front end, changing oil, changing transmission fluid and filter, flushing a radiator core with carb cleaner, tearing abart a whole truck so it can get sold in pieces, help put the truck on a trailer. 60 bucks. I love being a mechanic but this is a little much. Trying to act like this is charity work or some bs

 

Are you paid flat rate? Or what?

 

By job I think, but ive been working on the bosses truck


I changed the oil in a 2000 mustang today for a customer, not even sure if ill see a cent from it
