Q: You forgot to
mention the internet as a place to look for instructions on changing
cabin filters. Honda does not have the cabin location in the manual
(2012 CRV). Honda wanted to change the air filter and the cabin
filter for $129. I replaced both and saved $76, and it took a whole
30 minutes for both.
A: Yikes! I blew it
when cutting and pasting things, leaving mention of this information
goldmine who-knows-where! Good work renewing your own filters!
When contemplating an
automotive service procedure or simply trying to find out how
something works, often there will be someone presenting a YouTube
video on the subject. Another great site for information on a wide
range of automotive topics is www.aa1car.com, home of my favorite
technical writer, Larry Carley. His information is very well
presented! I also appreciate Tire Rack’s tech center articles,
which cover every imaginable tire/wheel question one could have.
Another source of information is forums, which are great for
assessing if a fault may be common, but take recommended fixes with
a grain — make that a handful — of salt! When curious about a
component’s characteristics — say, a window regulator prior to
door disassembly — I’ll often search as if to purchase the part,
to get a good look at a photo or illustration of the part. This can
sometimes provide hints on what may have gone wrong or how
removal/installation may play out. Please let me know of your
favorite information sources to share.
Q: I have been
noticing my engine cranking slowly first thing in the morning. I
remembered someone, perhaps you, recommending to give the battery
terminals a yank to check for looseness. Mine were tight, but one
was noticeably warmer, almost hot, compared to the other. They
appear clean. What does this indicate?
A: You nailed it!
Even though the cable connections appeared tight and externally
clean, the heat you noticed is a clear indicator of a poor
connection. There is apparently corrosion buildup where you can’t
see it between the post and clamp. Another way to confirm a reliable
battery terminal connection is to measure the voltage drop across
the connection, one meter lead on the post and the other to the
clamp while a helper cranks the engine. Greater than 0.2 volts
indicates the need for cleaning. Ignore the minus symbol if it
battery posts/clamps is easy using a Schumacher BAF-BI terminal
cleaning brush or similar. You’ll want to avoid erasing computer
memories by installing a computer memory saver tool prior to
disconnecting the cables. The accessory lighter socket type does not
work on many cars, as the socket isn’t “hot” with the key off.
In this case a tool that plugs into the under-dash data connector is
the best choice. A 10-foot cord on one of these would allow a second
vehicle’s battery to provide the needed trickle of electricity.
Keep doors closed/interior lights off!
