Thanks Ray. Magnetic oil pan heaters had been mentioned recently and
I got to thinking, wouldn't work on aluminum. Looks like it will be
frost plug or radiator hose style heater is I do anything at all.
All of the new chev small blocks have aluminum pans that
are designed to provide part of the structural strength of the
whole engine/trans unit. The 4.3 v-6 is like that, the Ecotec
is like that, the all aluminum 4, 5, and inline 6 are like that.
I missed the other thread when you were asking
about what type of block heater to install. My
personal opinion is that the block heater that is
installed "in the block" is by far the best. I've
tried the recirculating ones that go in the hoses and
I've never seen them really do a whole lot other then
heat that particular hose up real good.
When I was younger, I had a 71 Roadrunner with
a 383 engine. The previous owner (a tech that I
worked with) had installed a block heater in each
side of the block. "Dual" block heaters. When I
plugged that thing in during the winter, it started like
a dream, the temp gauge was already off the cold
indicator, and heat was coming out of the heater.
Well with that final bit I think it is decided for me. If I get one
at all, it will be a in the block frost plug type. I don't REALLY
NEED one since I hardly drive my Z28 in the winter, and I use
synthetic oil too. But another part of me always likes to be
prepared. Although very rare here, extreme cold temps of -40 F are
sometimes seen. Usually -25 F is the coldest part of winter where I

Just noticed the thread; so may be a bit behind... but
I qualify as a cold weather old guy; it's -37 degrees here
If it's of interest, and you only want/need it intermittently,
what I have on hand for visitors foolish enough to visit us
unprepared during the winter is an "electric dipstick"
Simply remove your oil dipstick, stick this in in it's place,
and plug 'er in. A warning though should you decide on this
route - "check the oil" with the heater dipstick first -
it *must* be well submerged in the oil, else there's a
tiny possiblity of an oil fire. Having said that, the
upside is that it can be rotated among cars - even
snowmobiles, snowblowers, etc if you can dip it into the
And if all else fails, what we did back when I was a
boy was just open the hood, sit a 100 watt trouble lite
on top of the engine, and close the hood carefully. It
And fwiw, I agree with the fellow that uses two block
heaters. Wonderful! In my case not for more heat, but
rather being old and retired I don't much anymore pre-plan
trips, so can't really use a timer. Instead, should someone
say let's go for coffee, I can turn it on and it's ready to go
in only an hour or so...
