How do I cool my turbo?

Drive your car gently for the last minute or two of the drive, or let the car idle afterwards for at least 60 seconds. By letting it run. the oil will continue to circulate and cool down the turbo.

How do you stop a turbo from getting hot?

Protecting your turbo from excessive temperature damage

Drive carefully – let your engine warm up before pushing it too hard, and let your turbo 'spool down and cool down' for 5-10 seconds before switching off your engine after every journey.

Do you need to cool a turbo?

Turbocharged engines do need to cool down before they are turned off. But in nearly all driving conditions, the engine does not reach temperatures that require a deliberate cooling down period.

How long should I let turbo cool down?

Idling the engine cools the turbo because it circulates the oil, yet does not make the turbo "work." The amount of cooling it needs is directly related to the way you just finished driving it. When you drive it gently around town, 15 seconds should be more than adequate.

What happens if you don't let turbo cool down?

That would allow the oil to circulate through the turbo and continue to cool it off before you shut off the engine. The danger, in those days, was that if the turbo was too hot when you shut off the engine, the oil might dry up and get “coked,” blocking those oil passages the way heart disease blocks your arteries.

5 Things You Should Never Do In A Turbocharged Vehicle

Why do turbos get hot?

Turbo chargers get hot because hot exhaust gases flow through the manifold then the turbo. So when the turbo is red hot, the manifold also glows with red heat. The temperature of the exhaust gas in diesel engines varies by manufacturer.

How does oil cool a turbo?

Oil as a Coolant

When the engine is running, the oil is a coolant that draws heat out of the turbocharger. But, for the oil to cool the turbo, it must flow. Restrictions in the oil feed or return lines can cause the turbocharger to operate hotter than normal.

How hot does a turbo get?

A turbocharger turbine lives in a terribly hostile environment. The turbine is driven by exhaust gasses that can exceed 1875°F (1025°C) and which are very corrosive.

Does coolant run through a turbo?

Another step some turbos use to help add to the life of the unit is water-cooling. This is done by connecting the turbo to the coolant system. By doing this, the turbo operating temperature is limited to the temperature of the cooling system.

How do you break in a new turbo?

Allow the vehicle to idle for 10-15 minutes without applying any throttle. Even at idle, the turbo can be spinning at as much as 28,000 RPM's on certain models. Use this time to check for any loose fittings, hoses, exhaust leaks, and to bleed the cooling system of any trapped air.

What should you not do with a turbo engine?

How do you know if your turbo is overheating?

Is it normal for a turbo to get red hot?

In summary, yes, it is absolutely normal for a turbocharger to glow red during normal operation. Glowing can occur with minimal drive time at a normal engine-load. The OEM's have recognized the heat that the turbo will hold and have appropriately supplied heat shields to manage that heat.

Why should you let your turbo cool down?

The key is keeping oil circulating through the turbo until the housing has cooled enough that it won't superheat the bearings, scorching the oil that's on them.

Do turbos get hot fast?

A turbo can run very hot indeed so that doesn't surprise me. Most modern turbo charged cars run the oil through the turbo for a few minutes even after turning the engine off for this very reason.

How hot is air coming from a turbo?

During compression in the turbocharger or supercharger the air is heated (adiabatic process) to the range of 230-260 °F. This hot intake air then passes through the intercooler where heat, if the intercooler is properly designed, is removed.

What makes a turbo spool faster?

A turbo can be tuned with a smaller exhaust housing that will spool the turbo quicker, and an exhaust wastegate can then be added to bleed off excess exhaust pressure at high engine rpm.

Do turbos get heat soaked?

Turbo Heat Soaking

Heat soak on turbo engines is a common issue on many factory cars. It's less common on completely stock cars. Though, certain cars and engines may be more or less prone.

Are modern turbos oil cooled?

Modern turbos now use water cooling, along with oil cooling to keep the bearings and turbine cool. When you turn the engine off, the water continues to flow throughout to cool off the bearings which in turn keeps the oil from scorching and sticking, since it is no longer flowing.

Does a water cooled turbo need oil?

Water cooled turbos have an additional water jacket around them providing additional cooling. Water and oil do not have an effect on performance (oil may have a minor effect) other than keeping the turbo alive. A "water cooled" turbo is in effect a water and oil cooled turbo and is the preferred option for longevity.

What happens when turbo overheats?

Transition from the body heat of the exhaust turbocharger to the central body causes burning of oil and corrosion of turbocharger bearings. The main damage occurs on the ring and grooves of the turbine shaft and the bearing of the turbine.

At what RPM do turbos kick in?

While your car's engine revs, at cruise, at around 2,000 rpm, a turbo's turbine can reach rotational speeds of more than 280,000 rpm.

Are turbos faster in the cold?

As air temperature increases the density of the air, and the amount of oxygen it holds, decreases. This means that the turbocharger has to work harder, spin faster and compress more air to produce the same amount of boost it would at lower temperatures.
