Brakes:
This is a major safety item and should be checked regularly by a qualified mechanic.
Pulling, soft pedal, no power, locking, grinding, or squeaking are some of the reasons
to get your brakes checked for safe operation.
Driving
Over 6000 Feet: In high altitudes your engine will have a 3 percent per 1000 feet
decrease in power and the idle will be slower. If you do not drive regularly above
6000 feet, it is not necessary to change your carburetor adjustments or the ignition
timing. If you do live at these high altitudes, check with local mechanics who will
advise you about how to change your ignition to suit the altitude.
Generator:
If your generator starts to make a grinding sound, the bush and/or bearing are badly
worn. This is usually caused by a fan belt being adjusted too tight. The belt should
not be "twangy" tight; it should have a little looseness, but not slip.
Cooling
System: Check the accuracy of your temperature gauge against a thermometer inserted
in the top of the radiator, with cap removed and car idling. Any temperature readings
over 195 degrees F on the gauge while driving, should be investigated to avoid overheating
and engine damage. Check condition of radiator and heater hoses and replace if they
are old, hard, cracked, or mushy.
Hubs,
Wire Wheels: Check the condition of the hubs by driving slowly in second gear and
going on and off the gas pedal. Listen for clicks coming
from the hubs. If you hear these clicks, your wheel could come
off while driving. Do not over tighten the knock-offs to stop the clicks. Clicks
could also be caused by a worn universal joint or differential.
Water
Pump: Hold the pulley or fan blade at the tip and move it. There should be no movement
or looseness. Look for a rusty stain or a coolant leak from the hole in the bottom
of the pump.
Electric
Fuel Pump: If the pump is old and dirty, you should replace it with the newest type
electric S.U. pump.
Battery:
Check that the specific gravity of your battery shows at the fully charged mark
of 1.280. If not, charge the battery and check the specific gravity again. If is
has not reached the fully charged state, replace it before if causes you a "no
start problem."
Leaks:
If your car leaks every time you park it, don't assume it could only come
from your engine. Check the transmission level and the coolant level. (Note: water/antifreeze
looks like clean oil.) Don't forget to check the engine oil as well. Keep a close
watch on all your fluid levels and avoid an expensive overhaul.
