cooling-coolant

hey now.got a friend building a mustang stroker motor,cant rember hoe we got on the cooling subject,but we are divided on thermstats and cooling...i maintain that without a thermstat,and running it hard you will over heat,reason being is that the coolant doesent have sufficent time to be in the radiator to cool down,he thinks more air means more cooling,anybody care to chime in with a link that would prove one of us right.....along with this most people will argue with me when i say you can die from hypothermia in 90 degree water,but it's still true...

You are wrong.

If only those who knew what they were talking about replied, this thread would still be on page one.

Re: cooling-coolant

I have ran a SBC without a t-stat and it never even got hot so I would have to say it will stay cooler without a t-stat.

Re: cooling-coolant

if u run a vehicle without a tstat in winter, it will never get warm enough to warm the vehicle up. thats pretty much it.

Re: cooling-coolant

When a t-stat fails it usually stays closed so it heats everything up.

Re: cooling-coolant

I've run most of my engines with no T-stat, but you need something to control coolant flow. Especially if it's a race engine that will see high RPM and high coolant flow situations. I just used washers that have the correct OD to fit in the housing and then changed the ID until I get the desired flow.

If the engine is used in a driver the only thing you will notice is the coolant will take a bit longer to warm up, but after that the temps will be much more constant. You should have some device to control coolant flow, whether static or dynamic, in the system.

A lot of things will cause an engine to overheat. Coolant flowing too fast thru the radiator isn't one of them. Wasn't that the original question?
