Sorry Romer - you deleted before I saw your PM.

Sorry Sumotoy - Shouldn't have made those quotes.

Still - you'd get a bunch more respect if you stopped weasling around and just flat out said that you were wrong, and admitted that radiant heat and convection are two different things, and trying to justify misusing radiant, by discussing the two types of convection, is just not a solid defence to being wrong.

This whole 'I"m not wrong even when proved wrong' attitude just really rubs people the wrong way.

Cool with me, just trying to keep the peace.:D

Thanks for your public apology
The irony is that post 48 appears to be the non tech version of 49. They both appear to differ only in applied terminology. Adopted and ready to move forward, I remain...

ready to vent...

Walking Eagle, firetruck41, medtro- instead of getting hung up on terminology or trying to turn this into a flame war at every turn, how about try contributing to the technical content of this thread? The pissing contest makes all of you look bad, esp. when SUMO is the only one responding in a mature manner, and guess what? Nobody really cares who wins the pissing contest portion of this thread. I seriously do not understand the aggressive and even angry posts on this thread. SUMO is trying to collect data, perform tests, and is doing so in an organized and systematic manner. If he is incorrect on terminology, just correct it and *move on* to concentrate on the the technical content instead of flaming. Sheesh.

SUMO- I have observed a slight rise in coolant temps (1-3 degrees F on my aux. temp gauge, but this is consistent) when I turn on my 14" pusher fan at idle along with the A/C. I'm assuming this is due to the warm air being blown from the condensor onto the radiator. Does this sound reasonable?

If he won't admit he is wrong on a trivial matter, what makes you think you can trust everything else he says? It's not that he is incorrect on terminology, he has a history of not admitting his mistakes, everything is suspect after that.

AC, appreciate the other words. Regarding the above, it could be from several things. More heat in the engine bay causing high intake air temps, more pressure in the engine bay reducing the effectiveness of the increased airflow, and/or a higher operating environment for the radiator, reducing it's efficiency at it's primary task.

One test you might try to do is see what temps are with no A/C on. That would probably confirm the condenser soaking theory.

Keep it technical and no more character comments. Take them to chat!

If you disagree, state so with data or just that it's your opinion. Otherwise, contribute or don't post in this thread.

As I told daughterofromer recently, "DON"T MAKE ME COME DOWN THERE!"
 
:bounce: :bounce: Thanks Romer... I appreciate everyones insights and effort but it was getting a little difficult to keep my interest in this thread.
 
This is a great technical subject and I would like to encourage POSITIVE discussion with ACKNOWLEDGEMENT of others points and COUNTERPOINTS that are constructive.


I'm starting to get out of my chair, you don't want me to come down there
 
Thank you SO much for this thread and the others in the series. Living in AZ with a recently purchased '96 LC that has 365k on the odometer you can imagine the frustration of having hot (not warm...HOT) air blasting out of the vents for 20 minutes of every hour. I'll be taking all of this great info and making this my next 'mod'.
 
So I could use some help with a cooling issue I am having.

Background info. Truck has entirely new cooling system. Koyo brass rad, Aisin water pump, toyota thermostat, Aisin blue hub with 20000cst . All cooling hoses have been done as well as the HG. There maybe 20 to 30 thousand miles on the cooling system and head gasket. Coolant looks dirty almost green. Coolant was last replaced when HG was done at Toyota. Not sure why Toyota would use green?

Truck never had issues with heat prior to being built. Now that it has armor (front arb with warn 12k, rear dual swing out slee and slee sliders) and 37s and drawers it gets hot just driving down the freeway. Never made it into the red but gets just below it.

I am kind of stumped. Why would an 80 with a new cooling system have heat issues? Could it be the thermostat is sticking?
 
Bump for help
 
With everything new or almost new, it shouldn't have a cooling issue. The color of the anti-freeze doesn't concern me, however, the description of "dirty" does. Maybe a flush and new thermostat to rule that out. Are all the factory air deflectors in place around the radiator and inner fenders? Could air be bypassing the radiator?
Pinched hose somewhere?
 
I am on board with the flush and first thing replace the thermostat. It is cheap enough if that is the problem your gonna kick yourself.
