Engine Temp. what have you noticed your 2020 running at?

[John8]

I got the app and the ability to see engine temp and other features and notice it is in the red most of the time, just a little above 220. This is going down the road with an outside temp of around 70 or so.

No bites? No one knows the actual temp of their coolant/engine at normal operating temps?

A quick Google search says it runs between 220 and 230 F

I googled a number of times in different ways. What did you google?

I wouldn’t worry about it if your car is completely stock. If your really worried about it, see if you can program your radiator fans to kick on before 220 to keep the temps lower...

Newer engines have a higher operating temperature for fuel economy reasons. Your engine is operating in the design envelope the engine was designed for so I wouldn’t be worried.

That's why the first thing I did was remove the engine cover and put it in the attic.

But won't that allow for more radiation of heat to the hood, which could over time, discolor the paint? I have seen then in the past, but it would also depend upon how much heat, since the cover looks designed to absorb the heat and there is no type of protection under the hood, as there is with some cars.

I've been taking them off my sport cars when they started putting them on to look pretty. They do hold heat in. No they do not absorb heat.

I took mine off of the FJ Cruiser some time back, no ill effects but seems the Supra runs hotter. The FJ is the best vehicle I have owned, so few, zero really, problems. Ok, took mine off. I used to rebuild engines (my own) and they have become so much more complicated. Not much fun any longer. lol

Supra is a turbocharged car. FJ isn’t. Turbo cars will always run hot under the hood. If you look closely, there is silver heat resistant tape on some of the wiring around the motor.

Sure, but my previous car with a turbo had some insulation and aluminum reflection under the hood but not cover like the FJ or the Supra have over the engine itself.

I recall a BMW "running hot" issue before. It's been over 5 years ago, but IIRC, one of BMWs' new release turbo I6 cars was running high oil temps, even reaching limp mode, in stock form. They gave the finger to buyers, who found the work around was installing a oil cooler. BMW then turned around and added oil coolers to the production cars. I've heard at least one similar example from Porsche, on the Cayman. It's the fact that the Germans, and others, don't stand behind their products like Toyota has. I've owned many Toyota/Lexus cars, but only one Porsche, a '18 911. I know turbo engines produce more heat. I also know that all makers experience issues, and that it is how those issues are dealt with that makes the difference. Toyota calling the warranty shots on the Supra gives me the assurance that I'll be treated fairly if problems happen.
I've heard no report of cooling issues on the MK5, even on tuned cars, so I'm guessing the Supra has a factory oil cooler, correct? Tunes I've been into, on off road machines, have provision to set the temp your electric fans switch on. You don't want them running all the time to keep temp down, if the car is moving...Heat kills oil faster, so use synthetic in FI engines, and be aware if your car calls for a specific high heat certified synthetic.

There is an oil cooler included.

The new Supra has 3 radiators cooling things down as well. Matter of fact, Toyota built in excess cooling capacity, then partially blocked the large front/center air intake. Tool out the stock vent grille for instant added air flow through that nice big air intake. Use the right oil, change it every 5-6K miles, and your not likely to run out of cooling easily, even tuned for 100hp+ over stock, possible well beyond that for all I know. The car is even set up for a rear diff cooler.
