We are leaving next month for a 5000+ mile trip from TN thru the Rocky Mountain states, friends will be tagging along we both will be driving cars and staying in B&B’s. Our friends have a 2017 Lincoln 4 cylinder with turbo. I know turbo’s can get hot, especially the main bearing after pulling a long mountain grade.

I also remember that cast iron exhaust manifolds get hot and coasting a long downgrade after just climbing a steep upgrade can lead to the exhaust manifold cracking which is one reason many passes have pull overs at the top for letting things cool down.

My initial advice to my friend has been that we should pull over at the top of a long climb and let the engine on his car idle for a few minutes while we enjoy the view and not shut the engine off or start the downgrade until the engine has had a chance to cool off.

I am a bit behind on this subject having never had a turbo engine so am seek any advice from those that know more than I do about the subject. Thanks in advance.

BTW, our car is a 2020 Acura V-6 non turbo with a transmission cooler recently dealer installed in case we wish to tow in the future.

Like you,not well versed in modern turbo gas engines,but I see no reason to stop for the cars sake. The view may be worthwhile though. Turbos have been on diesels for years and they never stop to cool them down. Now the new turbo Tundra....I would be afraid to take it off the lot until they figure theirs out.

I don't think this is necessary. A large % of cars nowadays are turbo equipped, this is not new technology and is a proven method of increasing power on small displacement motors and has been pretty reliable for the most part. If it was me, I'd run it and not worry about cool down.

Modern four cylinder turbos can handle it. They can climb a mountain like its not even there.

The only item that your friend needs to do is not to enter a gas station or parking lot and shut down the engine after a drive with the turbo running at/or near full speed, he needs to idle the engine for a few minutes and allow the turbo to spool-down, this prevents the turbo from starving of oil the bearings and from cooling, unless the vehicle is equipped with a spool-down oil pump that runs after the engine is shut down.

Normal day-by-day driving...... no, it is not necessary to idle the car/truck before turning the engine off. Check the auto manual and enjoy the trip. [emoticon]

Is the Lincoln turbo towing anything or loaded to the max inside the car?

I've created more than a hundred steep grades with an NTC 400 Cummins and never bothered with a cooldown. Most climbs had me shifting up and switching the Jake brake right away. What is important is to allow a 5 minute cooldown before shutting down. I have an oil temperature gauge to remind me. The oil I use is Delo 15W / 40. 14 gallons worth with the oil cooler.

The 2017 Lincoln's turbo is water cooled. The cooling continues after it's turned off by water coolant thermal siphoning.
