Engine Cooling System Efficiency 5.7 Hemi

Wow! 12 pages on how to fix a problem that doesn't exist.

Jack Daniels is gasoline. The real stuff is Forty Creek

...or diesel but I still like it.

...or diesel but I still like it.

I'll drink it in a pinch... or in a mix of coke or whatever, but I prefer whiskey with no mix or ice or anything. JD is too sharp at that point, Crown Royal or Forty Creek are very smooth and almost dangerous, almost like a liqueur, gotta watch the consumption rate before the lights start to fade out on ya.

Double Poppet bypass coolant thermostat

 

[Mister Luck]

A Dual or Double bypass system is what is now common in most current internal combustion engines.

“An approach to better thermal control is to make the bypass the primary path, and reverse the flow. This results in hot and cold coolant being blended before being pumped around the engine. “
The disadvantages are
“Modern engines require even finer regulation of coolant temperatures”

In my opinion
As advanced as our trucks have become the current market economy has made vehicle manufacturers produce budget friendly vehicles that combine vintage and modern technology.

MAP CONTROLLED BYPASS SYTEMS

Throughout the forums when the drive train components are discussed the subject of operating temperatures eventually comes into question.

“While engine wear becomes acceptable at 160F (70C), the sweet spot for emissions, power or fuel economy can be much higher, up to 230F (110C). What's more, there's no one right answer. The optimal temperature is dependent on transient operating conditions.”

“For leading edge engines, this problem is solved by implementing a thermostat map, controlled by the engine ECU. In other words, the engine temperature is varied according to RPM and load under computer control. The mechanism for this is an electronic thermostat”

I see the advantage of an electronic thermostat to be a monitored actuator that needs fewer physical inspections and a more comprehensive component accountability.

Other cooling system components have been modernized by electronic controls for example…
For some time now there have been electric water pumps and although they have their advantages they create additional loads to the electrical system.

The disadvantages of a mechanical water pump is, they are dependent upon a belt pulley system and draw power from the mechanical drive train and are reliant on engine RPM’s

Wow still at it !!!!!!

It’s not that unimaginable to retrofit a compatible device such as a map controlled thermostat.
It does seem as if I’m alone in this discussion but I’ve gotten this far at 13 pages and 6m views.

Thanks to all for bumping my post count up.
(couldn’t do it with out you)

If anyone is aware of a donor application vehicle.
In the mean time I’ll just research it on my own.

The map thermostats that are available are still actuated by a wax pellet but how much quicker is the heating of the wax compared to heated coolant from the engine?

Why wouldn’t an additional coolant temp sensor located on the upper hose or closer to the thermostat housing be more efficient?

Would relocating the CTS from the the top of the water pump closer to the thermo housing be reactively just as efficient ?

To reiterate an electronic sensor/ actuator would be proactive in monitoring device operating status or failure.

Let's keep the thread on topic, warnings and possible bans can and will be handed out to those that cannot comply.

Inside the red circle on what is to be reportedly the Tornado inline 6 for Jeep and RAM variants is a MAP controlled Coolant Thermostat.
Whether or not the housing is comparable with current models for RAM trucks is just a matter of time, but shows the need for a more resilient and adaptive coolant temperature managment sensor added to our current “budgeted” system.

Do you think that theory is because heat travels up ?

thermostat after pump in series, so with closed stat pump will cavitate and not overpressure the radiator. Additionally, whats the idea behind using V-6 fan? IS it electric? Wondering if it might save a little gas since I don't usually work my 03 too hard, with 153K miles and all original, save plugs and a battery change 3 years ago.
