2023-2024 Chevrolet Colorado 2.7 Turbo Engine: What You Need To Know

@Wojtek Swiezak I agree. My 2011 Chevy Colorado cost me $26,000 brand new. The dealer actually had taken $4,000 off the MSRP. The new Chevy Colorado cost about $45,000, then you have to consider excise tax and everything else. My truck is running great, the only problem is rust on the frame.

I like the idea that they pump coolant through the turbo to help keep it at a much lower temperature taking some of the stress off the oil but I’m sure it’s still a good idea to let it idle for two minutes before shutting it off

It most likely has an aux pump that runs after the engine is off briefly.

[@zman204]

So, I have a 2013 Cruze, I bought it in 2018, and now in 2023, I have 75000 miles on it. I just had the water pump replaced under a "special" warranty, that was extended just for that part to 100000 miles. The thermostat/housing was cracked, the water outlet was leaking, as well as the oil cooler. The last 3 items I did myself, and the cruze has oil as well as coolant lines that run to it. to change the oil cooler, you have to remove the exhaust manifold/turbo assembly, and my turbo was cracked in 2 places internally. That is what I fear with all these new small turbo engines, especially from chevrolet is that they are priced premium, yet built with sub par parts

[@OddBallPerformance]

Water cooled turbos don't really suffer from the same heat soak spike that occurs with air/oil cooled only setups, so idle time really isn't needed. If it makes you feel better though, go ahead. Can't hurt.

lots of things in common with the Toyota 2.5 liter Dynamic Force engine. Such as the electric water pump, variable oil pump. I like the Toyota engine better though because it does not have the 2 cylinder deactivation thing and also Toyota's port and direct injection fuel system to keep the valves clean.

[@thisdayage7997]

yea not having port injection paired with GDI and AfM is a deal breaker for me (the AFM thing baffles me& its been crap since 2008)! toyota knows if they’re going to build motors with longevity those 2 things are a must ! the 3.5 dynamic force & the 2.5 both got it right & im assuming the new 2.4 that will be in new 4runner & taco will share the same tech

[@toddwerther188]

Aren't these things designed to run hotter... can understand the port injection concern in a non-turbo, just unsure if the same issue on a hotter running turbo where the carbon is more likely to be burned. Also, not liking AFM because... it might save gas when going downhill? Do you really think it's active in normal driving? No. This is all 'feelings' based, would need some numbers to understand the complaints. Kinda reminds me of what people said about the Ford 2.7L when it was new.

[@csinalabama]

@@toddwerther188 Really two separate issues. GDI engines get carbon buildup on the valves unless port injected fuel cleans it off. It happens less with a high quality synthetic oil that is regularly changed. AFM engines activate when the engine is at speed and cruising. The AFM system causes lifter failure and oil consumption. There are lots of videos on GM's AFM problems. If you want to think the problem is solved, that is up to you. The issue of turbo engines getting hotter is a real concern. The oil breaks down faster in a turbo engine and should be changed no later than 5k miles. Turbo engines need better heat management than non-turbos, so do your homework on heat management before you buy a particular company's engines. For example, look at all the problems with head gaskets on small Ford turbo engines.

Thanks for getting more specific than I have seen elsewhere, about exactly how the base engine is "de-contented".

Here's is what my mechanic told me. Carbon actually absorbs gas and with lower your mpg on an old school set-up then hardens making it impossible to burn off if not treated. We all know how a DI system works. Dump in Seafoam every oil change and it will keep you running and help remove it. How, since no fuel hits the valve? It does what the bottle say. Lubricates the surrounding areas and with vapor from Top Tier gas will clean it up.

[@DavidGarcia-vh3ul]

Most likely turbo is maxed out. On old Dodge Daytona's with a 2.5 litre turbo engine that came with a tiny Mitsubishi TEO4 turbo and when you bumped up the boost the same thing happened.

[@AkioWasRight]

Because the torque is spread at lower RPM, not higher RPM to increase peak horsepower. Horsepower is just function of torque and RPM. You can increase horsepower and torque at any RPM outside of peak horsepower RPM, which can inflate your peak torque figure yet still maintaining your peak horsepower figure.

[@K707OR30]

My guess is the ECU maps between the two calibrations are basically the same at ~5k RPM where you'd make peak HP, and the bigger difference is in the lower RPM range around 2500 or 3k on the HO map and they've calibrated the wastegate to stay closed and build more boost there versus the "plus" map. So your 7 PSI difference between the two is probably in that 3k RPM range for the peak TQ difference, and otherwise have identical timing and boost mapping at 5k and making the same peak HP.

I ordered a Colorado LT 4x4 with the L3B - HO. I Can't Wait !!! I didn't want to pay the ZR2 price so I got a lower trim level with all the power. We test drove a 4x4 Ranger and compared it to the 4x4 Colorado. The Colorado won "Hands Down" ! The hard part is waiting three months for the build and delivery.

I'd rather have the standard suspension anyways. The ZR2 is a lot of weight, a lot less capacity, a lot worse mileage, and a lot more strain on the components.

It is a complex engine and while it works it is impressive but how long will it last and when it does need repairs will it be able to be fixed without breaking the bank or will it be more likely replaced instead of repaired because of the cost.

I have a 2018 LT Colorado and has the 3.6 L engine. During the summer it gets close to 28 mpg. Now I am very disappointed that this engine is being done away with in the Colorado. The 2.7 turbo engine gets worst fuel mileage than the V6 3.6 L engine. I think that can be a mistake because many like me really like this engine. I do hope that in 2024 GM decides to also use the 3.6 L engine again. The mileage on the 2.7 tubo is less than the 3.6 engine and fuel costs are high.

[@Shadow-lq7rx]

are they higher when cruising on the highway or overall?

[@xaviervera90]

Overall ​@@Shadow-lq7rx

[@fz0gtg]

The downside of the V6 is that it requires high rpm to produce its power where the I4 Turbo produces power in the form of torque over a much lower and wider rpm range which considerably improves drivability! From my experience this is quite evident when towing on hilly terrain!

I'm in the market and this is the way it is going, not by market demand but by demand of the W.E.F. and the traitors in D.C. With that said the Toyota is also going to a 4 turbo and is $10,000 more?

It's not entirely about rpm. It's about engine load and throttle position.

[@mrtopcat2]

The reason why simpler engines are preferred, because on the long rum, repair costs may outweigh the fuel savings. That said, from what I have seen so far, this engine has been designed very well and sturdy. The only Achilles heel I see is the necessary periodic de-carbonization of the intake valves as well as the fragile roller rockers of the valve train. These issues may show up eventually around 100k.

Thanks for this video. I just went to Chevy's Colorado Build page and looked at the base engine (L2R) paired with the (N8R) transmission vs the optional higher output (L3B) paired with the (MFC) transmission. My question is, is the (N8R) transmission code = 8L45 transmission, and is the (MFC) transmission code = 8L80 transmission? I would assume so. It seems that if you custom order a LT trim variant with the 310hp engine, the vehicle will be built with the (L3B). However, if you want to "flash" the base engine after production, the vehicle will be delivered with the (L2R).

[@coop4274]

Actually you have it backwards. If you want to get the updated HO flash then you need to order the truck with the L3B. The flash isn’t available on the base engine.
