My engine doesn't run 'cold' and there is no moisture in my oil, ever. I've checked my mileage a number of times and it is always at or above what Chevrolet says it should be.
Many head gaskets have been blown by stuck thermos, with the cars ending up in a junkyard as a result. At the very least it's an expensive repair job for those who can't do this repair themselves.
Again, those living in cooler climates shouldn't remove them.

 

Funny I haven’t heard of a single one

your engine definitely takes longer to warm up. Have you tried putting the thermostat back in as a control to see what kind of consumption you get?

 

lol just bc you don't see it doesn't mean it not happening.

...don't promote it as something its not. Its not better.

blown head gasket seem to be your big worry; if you 're scare you stat will stuck close; they have failsafe stats google it.
you have the same chance of blowing a water pump belt or chain tensioner and overheating


engineers want the thermostat in place. Even when the stat is open it acts as restriction that increases system pressure. This is improves flow to low flow areas and increases the boiling point of the coolant.

 

if your cav has to have the stat out to run cool....you got other issues

 

If you haven't seen a single blown head gasket due to a sticking thermo I would politely suggest that perhaps you haven't been working on cars for too long.
Guys like us, who keep an eye on what their cars are doing, know what to do when they stick. But many other people, especially females and the otherwise mechanically illiterate will blithely continue driving 'to get home!' and blow a gasket. It happens.
And yes, I'll go ahead and stick one back in and see what the difference is.

 

Over 20 years. I do all my own mechanical work. Neither I nor anybody I know, family friends coworkers etc, has had this happen.

I guess your car is magic and breaks the laws of physics.

 

if you need to compare references lets do it.
What he is saying is right. Don't promote myths.
The only time running without a thermostat is better...is when the stat is stuck closed....but in no way is it a good idea to remove a properly functioning thermostat and run like this all the time.

 

You may be able to get better fans, but I don't think it's worth it, that's not hot enough to being doing any damage, just enough to worry you. Mine does this in the summer too, as soon as I get moving it cools down again, I've just been assuming it's because the radiator isn't getting as much air flow, since it's not moving. My fans are running, but there's only so much 19 year old fans can do in 90+degrees. It gets hot if it idles for more than 5 - 10 minutes depending on how hot it is outside. And honestly, I drive a cavalier, I don't have idle for 5-10 minute gas money and just turn my car off. It prevents it from getting hotter and saves gas.

 

for cav's only...if the heatercore is plugged the engine will run hot.

 

MY 02 does the same when stuck in slow traffic on hot days. I just turn on the heater and the fan, and that brings the temps down. Yes, it does make the cabin even hotter, but that's better than blowing a head gasket. Twenty years old, still runs great, never had any serious problems.
