Hole in halogen headlight |
|
|
I just noticed there is a small hole in one of the halogen headlights
on my pickup. The light still works. I know there is a separate bulb
inside of these halogens. Since it works, it seems senseless ot
change it. Is there any danger to using it like this? Could I
protect the inner bulb if I put some clear silicone caulk in the hole?
The hole is about 1/8". Probably a rock hit it. Cash is tight right
now, and this is not my daily vehicle, just something to haul stuff,
so if I can patch the light, I will.
Any suggestions?
Thanks
Mark

Good idea to use silicone sealant on the hole or any cracks. Water
and road crud will find it's way in there and mess up the mirrored
finish as well as blow out the bulb on hot contact. You wouldn't be
the first or last person to do this.

I have done that on several. RTV sticks nice, but be careful what kind
you get. If you have a modern vehicle with an O2 sensor, you need to
get 'sensor safe' silicone because the fumes from the regular stuff
kills sensors fast.
I know folks that have sealed a diff cover with regular only to kill
both O2 sensors from fumes in the air.

Mark, I've used GE clear silicon sealer in the past rather than automotive
grades. The GE sealer is meant more filling small areas. It doesn't yellow
either.

This is a 79 Ford F-150 pickup. Does it have an O2 sensor? I kind of
doubt it.
Just how touchy are those sensors? In other words, how far away does
the silicone have to be? I mean, a headlight it pretty far from the
engine, and if the engine is not running, how would it get in there?
Or. for example, if a car (with an O2 sensor) was in the garage, and
used some silicone on my work bench, (with garage door closed) will
that cause problems? It sounds like those things are real touchy. |

Really touchy. Lots of folks have had trouble on Jeeps because they
change the diff fluids fairly regularly and think that is far enough
away or something yet they still get tagged out in the open air even.
The fumes do tend to hang in the air for a long time. I wouldn't use it
on a work bench in a closed room with a vehicle near, that's for sure.
That 79 might have a sensor, depends on where it was sold. Does it have
a cat and feedback carb? If so, it has the O2 sensor.

It dont have either of these.....
What other things cause these sensors to fail? You said Differential
fluid and silicone. Are there other things?
How does it affect them? (I mean scientifically). I find it hard to
imagine how a few vapors from silicone or diff fluid could do anything
other than stink. And, if the engine is not running, how does it get
into them?

Sorry for the confusion, when changing the differential gear oil, folks
normally use silicone for a gasket on the cover. It is the fumes from
this silicone that nails the O2.
The sensor safe RTV stuff is way more than twice as expensive as regular
RTV and for household silicone sealer, likely more than ten times more.
It is worth it....
The fumes are persistent and as far as I know just get in the reference
air passage on the O2 sensor itself and it's instantly dead. The
sensors have an air passage to allow a reference air sample, some of
them have a hole and some have a space between the plug and the wire for
this so those you aren't supposed to waterproof the plug with dielectric
grease or anything.
I have been told antifreeze and engine cleaners getting on the O2 or in
those holes will kill them also.
If you think about the closed garage scene someone mentioned. 'You' can
smell silicone everywhere in there, well so can the O2 sensor.
The O2 acts like a chemical/heat battery. It uses the difference in
oxygen in the outside air compared to the oxygen in the exhaust to make
power. I believe they die because the silicone fume molecules in the
air coat or maybe chemically combine with the electrode so it can't see
the oxygen molecules. Oxygen is only a small percent of our air volume
remember.

You might try to find a lens-'rebuild' kit, made to cover, waterproof |
and inspect-proof lenses with holes. Used them on rear taillite and back-up
lenses. Kit even contains several pads to make various "dimple" effects to
approximate originals. I feel like the part of the kit that 'rebuilds'
back-up lenses might work since it is clear also. HTH & good luck, s |
