Engine temp "fixes" on the 3.6 is another solution looking for a problem.
NORMAL temperatures can be in the 220s but people freak and insist there's an issue if they see over 200 or 210. And the people freaking are those who aren't mechanics, techs or engineers. It's bad info passed across the web.
So what if it runs over 210 or 220?
The specs for a properly operating thermostat say it should begin to open at the temp stamped on the stat (195 for example) -the stat should be open 0.003" at the designated temperature (such as for a 195 - at 195 degrees it should be open 0.003")
Full opening isn't until about 220 degrees. That's a normal or new thermostat as used in engines for decades. For a 205 stat it should be full open at 228. Interesting, some engines set the minimum operating temperature at 205 and don't care if it's running in the 220s, it's normal.
On most automotive temperature gauges, the top of the NORMAL range is around 240 degrees. So for decades, it's a given that normal temps can reach 240. 240 is getting up there, but not panic time. It's not going to blow up.
These cooling systems can handle temperatures of around 260 degrees with the 16 psi cap and a 50/50 mix of coolant and distilled water. So if you have a good cap, good coolant, 220-230 is still very acceptable.
Why are people concerned about temps over 200 or 210 or even 220? Because the internet says they should be concerned.
Engines actually produce the best power and efficiency at those temperatures. You want cold air in to have the density, but the engine operating temperature needs to be hot, not under 200.
Unreal what is out there on the internet about engines and temperatures. And it's all from non-trained non-experts copying bad information around the web. And the more it's repeated, the more it becomes fact or truth.
I want my engine to be running 200+ degrees, I don't want it to be running cold.
I've run full gauges in most of my cars since I first started driving.
Solution looking for a problem. These don't run too hot.
No wonder people are so confused when they see their temp gauge for the first time and it's running 220 - people are telling them they need to freak out.
Where are these freak-out temperature numbers coming from? Who is telling people xxx is too hot for coolant and yyy is too hot for a transmission and so on? Non-techs, Youtube, etc.
