Radiator Fan

[scott woodward]

My stock engine water temperature meter reads about 1/4 when I'm putting
around town. On the freeway (55-60 mph) it gets very close to 1/2. I'm
concerned that I may be getting close to overheating.

I've just installed a new fan clutch and I haven't heard it kick in. I
figure that if the fan clutch doesn't cut in, the temperature must be in
the ok range.

People tell me that when the fan cuts in you certainly will hear it. Can
anyone comment on whether or not this is true. An explanation of what it
sounds like when it is engaged would also be helpful.

Thanks,

Scott

When the fan kicks in it sounds to some people like the transmission has
kicked down a gear. You won't miss it. The temperature guage does not
register as you might think. Normal operating temperature on a stock unit
will register about 1/4. When you reach 1/2 or more, you are running pretty
hot.

Scott, The original temp. sender will show 1/2 scale at 250 degrees,
which is boiling point with standard pressue cap and proper anti-freeze
mix. Go to NAPA auto parts, get a TS-6469 sender. It will read full at
250 and 1/2 at about 200. My fan cuts in at 207 but it is not original.
With digital read out I run between 178 and 199 most of time in warm
weather. Hope this helps. There have been a lot of engines damaged
because of that sender.
