There is no advancement to this thread, this "issue" was addressed many posts ago, the OP does this repeatedly (read all his threads), attempting to turn mole hills into mountains, if you choose to play his game then by all means proceed, but i for one am checking out of this nonsense, peace.

 

Meborder, I see what you're saying about heat transfer, that may well be a part of what's going on. I may heat up some coolant, and some water, and see which one cools faster. If the coolant holds the heat longer, that'll be all I need to see.

There is still the issue though, of the thermostat leaking. I'll have to do a test with a really strong coolant mixture, and see if the gauge temp lines up better with the time I first feel heat from the radiator. With the weak mixture, the radiator under the inlet was hot at around 155*.

Thanks for the info though, just more food for thought.

 

And to you montana, I'll make this short and sweet.

My father, a lawyer, and one of the smartest people I know, has always told me one thing about arguing with people:

"Your greatest challenge will never be the day you face your most worthy opponent, it will be when you come up against the most irreconcilably stupid one."

It has taken a genius of your magnitude for me to finally realize what he means.

 

Johnnie Cochran, an attorney, one of the smartest there was, quoted verbatim, "If it doesn't fit, you must acquit", perhaps your father should find another profession, one less despicable.

 

I throw my nickel in this for the hell of it...

A lawyer does not argue for what is right or what is wrong. A lawyer simply argues cases for the sake of winning the argument - regardless of what side of the argument he or she is representing.

Think about it... that's why they're typically despised.

 

Don't confuse "heat transfer rate" with "heat capacity"

Heat transfer has to do with how well a fluid receives or disperses heat from one medium to another, or to itself.

Heat capacity is how much heat an object can hold. They are similar but different. (google it for a better explination)

As for your experiment, go for it if you wish, but it is commonly accepted that a 50/50 mix of antifreeze/water has the best rate of heat transfer. If you do not live in an environment with extreem temps, and a 50/50 mix will give you sufficient freeze/boil over protection, then that is the mix I would use.

Antifreeze also reduces the skin friction of the water and allows the coolant to produce a better "contact" with all of the microsurfaces within the engine, allowing more opportunity for the coolant to pick up heat and disperse it throughout the system. (google "water wetter" which is another product you could use if you wish)

I'm not sure what to do about your leaky t-stat, however, I'd try a couple different brands and see what happens. I've always used Stant's Superstat with good luck, aside from the one bad one i got last year (only one ever, for me). Also, selling parts for a living for quite a few years, they had a very low rate of return from customers. Don't get the cheap Stant's, those came back all the time and were only sold (by me) under duress.

good luck

 

Sir, one last time, politely and plainly, please do not post anything more on this thread.

Thankyou.
