im not sure that the thermostat is clogged. i think it may jsut be a bad
i will look into burping it as i have not done that yet.
also, going to chekc the heater hoses when i get a chance
I took that silicone fan off and fired it onto the bush where it
belongs. Now I have a flex fan that is directly coupled and my
heater works fine.
What did people do way back before that clutch fan nonsense became the
We didnot Need one !! That was Before They relized that The Fan Actually
got in the Way of The cooling systen after 60 MPH !!
It actually Blocked Fresh air from coming thru the Rad fins.
My Family OWNED a LARGE Salvage Yard From 1944 till 1974.. and we sold
it,, it is still in operattion today.. And Back in the 50's cars
with 40,000 miles were real Rare. The engine wud blow around 35,000 (
When we Disassembled the engines for the Cast and aluminum pistons, We
noticed that Engines that used Pennsoil and Shell X-100 oil were gummed
up the most.. ( Pennsoil was the worst)
Standard permalube engines were the Cleanest followed By Quakerstate.
Valveoleen was clean also.
As you can see we NEVER used Shell or Pennsoil in any of our Machnery
or Tow Trucks.
I wish I had only 1% of all those Cars i cut up with a torch, I wud
be a Zillionare if I sold them today !!
lots of 57 Chevy's
The 55 Chev 265 had a Hollow Crank, So if it got hit in the Front , Good
buy Engine., We Learned to NEVER bid on a 55 chevy V-8 if the front was
damaged .. My first car was a 1953 Bel-air With a 235 6cyl and 3 CARBS
( Single Barrel Carbs ) on it.. Great for Street Racing, Until the Cops
got me !!
Geez, there isn't anything wrong with a properly operating
fan clutch. Why have something spinning around using horsepower
when it's not required? Most of the 2005 trucks models now have
completely dropped mechanical cooling fans...they are running
twin electric fans up front. I love it....the big fan shrouds are gone,
you can get at the front of the engine now real easy.
The clutch fan is the best compromise for mechanical style fans. Flex
fans pull a lot of air but you have to be up in the RPMs to get any
air flow. Of corse this applies to the clutch fan also. The flex
fan, at least in my view does not pull enough air at lower speeds. If
you have A/C and it the middle of the summer air flow makes a
difference, especially if you get stuck in traffic.
I too read where the 2005 GM Pickups have dual electric fans. I've not
been able to look at one yet or been able to find any pictures showing
the setup. Anyone know of any pictures or illustrations on the GM
trucks, showing the fans?
I would think that if you have two good sized electric fans that pull
air through the radiator at a good rate and they cover most if not
all of the radiator area on the rear of the radiator, that they would
perform rather well. There are a number of cars that run fine with
I'm about to try a dual SPAL fan setup on my truck. Currently I have
a fan clutch setup with aftermarket radiator that runs ok. The
electric fan setup will be somewhat of a test to see how it performs.
I wonder how hard it would be to adapt the new 05 dual fan setup to
older model trucks???

An aftermarket thermostat will act like that within short order. My
experience is "Buy cheap, buy twice". An OEM thermostat will run only
about twice as much as the el-cheapo brand but it will last at least
three times as long and the heater will smoke the hair right off your
legs in the bargain.
I live in Northwestern Ontario where it gets pretty cold sometimes.
Ok i changed the thermostat AGAIN and now my engine is
running at a higher temp up to about 195F and moving up
and down and the thermo opens and closes.
Still not much heat.
When i park it and rev the engine i get LOTS of heat.
Also after i do that, the inlet heater hose is red hot and
the outlet is vert hot.
Im guessing that the heater core takes some heat out
of the antifreeze int he process of making warm air.
Any ideas of how much heat is taken out ? lots / little ?
Anyway, from this it seems to me that the flow is not going through
my NEW heater core the way it should be, until the engine is really revved up.
So, i guess i will check the heater core hoses next when i have a chance.
i changed the long hose and the old one was clean as a whistle.
i didnt change the short one, becasue it has some kond of crazy connector
on it and it will cost me $60 for a new one.
but i checked it and it seems clean too.
still not much heat. even when its warmer outside i dont get a lot of heat.
So it looks like im down to :
- air in the heater core
- heater vent not operating correctly.
the hoses on the heater core are both pretty hot.
the one from the engine is too hot to grab onto.
the one coming out of heater core i can hold onto for maybe 1 second.
so they're pretty hot.
anyone have any experience getting at the vents in the dash ?
i took out the glovebox and i couldnt really get at anything there.
