Engine Cooling System Efficiency 5.7 Hemi

Ahh don't you miss all of those vehicles on the side of the road on a hot winter day when they were running low reid vapor pressure fuel.

No.

North of the border we never had any winter issues,but a hot summer day meant there would be a few that wouldn't start after driving to town/city and letting the car sit for a bit,and the fuel line between the fuel pump and carb would heat soak and boil the fuel in the line.

 

[HEMIMANN]

And then we waited....and waited...and waited....(for the damn thing to cool down).

Good thing we weren't in as much of a hurry in those days, for the most part.

Alot of people carried enough wrenches in those days to loosen off either the filter or fuel line at the carb or fuel pump,lol. I grew up in a farming community,and the local town was angle parking,and on a hot day,you'd see the majority of vehicles parked with the hood up,lol

Oh how I remember the vapor lock days! Tried everything, eletric fuel pumps of all kinds and nothing worked. I forget when the Chrysler brand cars started using the fuel filter with the small vapor or return pipe on them back to the fuel tank (mid to late '70s) but I started putting it on everything I owned afterwards and it solved the vapor issues for me.

And then they added them to the 4 cylinder cars - and a bunch of them leaked fuel at the seam and had to be sealed. hahaha

Up where I live you always had a big-a$$ flat screwdriver to prop open the carburetor(s) choke plate when (not if) the engine flooded during subzero weather. Of course, this improved one's feel for accelerator pump pumping prior to, and during engine cranking to hit that interminable engine pop point. Standing out in -20F and blasting wind'll do that for ya.

That brings up the other issue with a carb on a cool humid day, carb icing.Ah the good ole days,when you'd carry a towel with you to throw over the carb to get some heat soak into it,lol

TOWEL sometimes helped when the CARB puked and U had a lil fire going, or if U had a brain dead day and sprayed too much ether sometimes to get started, lmao.

It definitely been worst since the pandemic, I for one am hopeful you mousekateers get a chance to go outside and put your bottles away and dryout.

Although I’m kind if going to miss all this affection

Oh yeah, backfires always fun, tell the newb to lean over when cranking.

I use a 180 thermostat because of towing and being in the mountains.

I don't see how moving to a 180 helps with towing and heat. In my truck I see sustained temps while towing at about 220 to 230. When I climb a long hill it can jump up to 245.

Note that at all those temps (220, 230, 245) doesn't matter what thermostat you're running, all of them would have opened long before that.

What we really need, is an external oil cooler that activates at 220.

That's easy enough to cure. These are available in 3 differant opening temps 185 / 205 and 215

Your 19 should have FCA's so-called oil heater/cooler,which puts oil heat into your cooling system,and puts your cooling system under more stress

What's the idea with this system? Obviously heat transfer, but what's it supposed to accomplish?

As far as i can tell,it's to speed up heating the engine oil more then it is to cool the oil.They started to implement it about 2017 ,before that it wasn't employed. The older trucks with-out it,seem to do better with coolant temps while towing,then the later trucks with it do from anything i've gathered up. Think Cafe and EPA,lol
