Greetings
again,
In the previous post, I
labeled the ports on my radiator, and now I'm confusing myself
:-)
When I was talking to Bruce
about my oil temp issues, he suggested that I run the (currently plugged) heater
output into the radiator inlet to produce some more coolant flow through the
radiator. This would be in an effort to increase the efficiency of the
oil/water heat exchangers when the thermostat is closed, and there's little
water flow. If I prove that I need to lower my temps, I'll try this.
Certainly, water
will actually flow from the heater port to the radiator inlet tank, because
Bruce said Mazda used to do this with the 1st gen oil/water heat
exchangers.
Since water will flow from
the engine to the radiator inlet tank, why do they return the heater itself to
the radiator outlet side. This is also true for the AST, and turbo as far
as I can tell. I certainly plumbed my AST and turbo returns back to
the radiator outlet tank, so in effect, they bypass the radiator. The
volume of water is small, so it's probably not a big deal, but it just seems odd
that they wouldn't return all the water to the same place. I initially
thought that maybe they made an exception for the oil/water heat exchanger
return, since it would be picking up heat, and they'd want to pass that through
the radiator. Of course you'd think the same would be
true of the turbo water return.
I'm not sure there's really
a question here, but if it happens to make sense to anyone, let me
know.
As for the oil temp saga, I
should have an oil temp reading into the engine by this weekend.
Thanks,
Rusty (waiting for oil
temp sensor supplies)
