comment Hour meter stopped turning
Typically the hour meter inside of a tach is driven off the same input as the tach itself. If there's any signal to drive the tach, the hour meter is driven (usually as % of RPM, so 1 hour at 100% = 1 hour indicated and 1 hour at 50% only shows 0.5 "hour"). There are hour meters driven by oil pressure, but that's typically a stand-alone unit (and measure hours like a normal "clock" hour).

comment Where'd my heat go?
Probably not. My replacement costs were $12 for the thermostat, $26 worth of coolant, and $85 (an hour labor) to have a local shop do it so I wouldn't be stuck cleaning up the big mess that happens when the upper radiator hose is removed. :-D

comment Where'd my heat go?
@Rory That's the opposite of what mine would do. While I was moving the coolant temperature, and therefore heat output, would drop (due to all the airflow that was cooling my overactive thermostat), but when parked I'd get heat since the radiator couldn't mistakenly dissipate too much heat... :-)

comment Why is there oil pooled around the spark plugs on a 2.0L Zetec in a 1998 Ford Contour LX?
Be careful retightening... Some valve covers are quite low torque. I was used to higher torque valve covers but ran across a low torque one once and accidently tried to torque it to 11 ft-lbs instead of the indicated 11 in-lbs!.

comment Does a car lose its pickup with age?
Catalytic converters only get plugged if something else fails. I've got one car with 255,000 miles on the original converter. The other car has 120,000 and is on its third converter. First one died due to fuel pressure regulator failure excessively richening the mixture. Second failed due to ignition power transistor failure, which let raw gas go through the exhaust while I was trying to restart it while coasting to stop. Oh, still made good power, put 267whp down with the clogged converter, with chunks of catalyst shooting out the exhaust (that's how we found it was clogged).

comment Is this gouge in the side of the tire a safety issue?
Yep, that's one to be replaced sooner rather than later. There may not be much rubber left under there, the sidewalls of tires are quite thin compared to the traction surface.

comment Why rear disk brakes do not wear the pads even?
If the bearings and calipers are all in good shape, you shouldn't see any brake wear from improper alignment. It should all show up in the tire. However, with worn bearings you may see some brake wear issues.

comment How do you detect and deal with a freon leak?
A mechanic with the appropriate tools can test the system to find the leak(s), then make recommendations on repair.

comment How do you detect and deal with a freon leak?
Yeah, I've given up on A/C on my cars. I've gone ahead and removed it from both of them now. Luckily the climate I live in only has me seriously suffering a couple days each Summer.

comment If one coil spring needs replacing, do I need to replace both?
I consider it case by case. Standard logic is that both wear at the same rate. However, that doesn't take into account side specific loads and/or damage. Most cars have springs that should last a lifetime in normal use. If you nick one, you've significantly shortened its lifespane. Might consider doing just 1 in that case. Racecars, 1 side only is standard (as the load is asymmetrical, even on road courses (as they're primarily right hand turns and the driver is typically alone and on the left side of the car)).
