Heater hose sizes?

[Ecomike]

Yes, I meant open loop.

I always read that 210* is normal operating temps and running down at 180 is too cool for the engine.

The 180 to 210 range has been HOTLY debated at times here.

What point on the temp gauge indicates 180*? I read on here before that it was actually set up as a log scale.

For an exact, real temperature I no longer trust the dash gauges. They are good for direction, size of T change, but they are rarely calibrated.

I use an infrared hand held sensor under the hood to verify localized real temperatures on mine and then correct the actual dash gauge reading for what I read with the IR gauge. Right now my dash is reading about 35 F too low compared to the thermostat area measurements I am getting. I am also getting a 20 F rise from the rear of my head to front.

What part of the engine are you taking teh measurement from? I have access to an IR thermometer.

Well, I just found a leak in the radiator. Just a tiny amount of coolant. Leaks from the lower, driver side corner. Also leaks trans fluid in that corner as well. Almost impossible to see with the e-fan installed.

This can explain my poor coolant temps ... loss of pressure in the system. Looks like I've gotta get a new rad to put in.

If you need an easy temp. fix, get some JBStick. Kinda like a 2 part epoxy putty. Sets in a few mins., cures in an hour. Helped me get home from work (~30 mi. highway) on a leaky rad. Held for a few days til I got new rad.

I was kind of thinking something like that, but it's nice to get clarification that I'm not totally crazy.

Just mosltly/partly?

Well, I'm not exactly sure where the leak is from, because it leaks just ever so slightly. I think the trans leak is from the fitting where the fluid hose goes into the rad.

I already knew i was partly crazy.
