Chevy inline 5 any good?

5 cylinder, sounds like GM spending millions for nothing. Especially since they are not being made now.
But I guess they have to give the engineers something to do for what they pay them. Easy just raise the price of the product. 🤣

It's based on the Atlas 4200, Not much money to delete a cylinder & run Balance Shafts....Designed from the beginning to be 4, 5, or 6 cylinders.
 
I’ve owned an 07 Colorado with the four cylinder version of that engine and two SUVs with the six cylinder version of that engine (owned an 02 Envoy before and now have an 04 Trailblazer).

No engine issues with any of them. I’d say they are fine. Apparently some had issues with the valves or heads but I’ve never experienced it.
 
The 2010 will have the 3.7, I had the 3.5 in my 2005 Colorado. The change to the bigger displacement was to correct a head gasket issue that was known on the 3.5. Having said that, I drove mine to 205k miles, then sold it to my brother-in-law who beat on it for another 30k or so. The motor was great. Plenty of power for the truck. Fine for light towing. There is nothing to be afraid of, I'd buy another.
I had both of those years and the 3.7L came with the 2010 …
No issues at all - decent power for the vehicle size …
These were held back some by only having a 4 speed in that era …
(think the 3.7L would do well with a 6 speed)
 
2007 GMC Canyon 3.7 5 cylinder original owner. It now has 280,000 miles on it. Only real issue was leaking valve cover gasket at spark plug holes. Had to loosen intake mainifold(PITA) to remove valve cover to replace gasket at 200,000 miles. It has gotten oil changes at 10,000 mile intervals with “full synthetic” oil since new. It has started to use a quart of oil every 5,000 miles. Still runs great!

yeah, the valve cover gasket is a PITA. My coworker's Canyon with the four cylinders has been leaking for months and he's putting off changing it. And I did it on the Envoy I used to have. Took us several hours!
 
That 5 cylinder was also available in the H 3 Hummer wasn't it?
Yeah and that vehicle could have really benefitted from the 4.2

I service an '06 H3 with about 240k, but that vehicle is held together with duct tape and string. Has questionable hot oil pressure and seems to run warm -- I really wonder about the head gaskets

I look on Carguru once and a while - they always have some very high mileage 355’s and don’t give them away …

Drove a Colorado at work with the i5 and it was great motor. We had 2 of them and never had any issues for many years of use. I had the 4.2l i6 in my Ascender and it was trouble free except a bad cat once and that was from oil burning. Got that resolved and cat codes went away. Had ~180k when we traded it and saw it for several years after that around town.

My neighbor and his FIL have 7 or 8 trailblazers between them and they run them up to and over 300k regularly. They buy them and store them until needed or they become parts trucks.
 
Looking at getting a 2010 chevy colorado with the 5 cylinder, is this a good motor and what should I look for on the truck. Thank you.
The 5 cylinder is not any easier to service than this 4 cylinder. Just a little glimpse into it. Some go forever, some fail early. Hit or miss with those Colorado's, just like modern day Hyundai/KIA.

That’s not a realistic comparison - those motors were not blowing up left and right on the road … I had both the 3.5L & 3.7L - all they really needed was a 6 speed or 8 speed like engines today have …

My friend in New York had to junk his HUMMER due to rust, while the 5-banger engine was close to 300k miles. But that doesn't take away from the fact that when something goes wrong - they're a nightmare to service.
 
A woman I worked with had a 2009 or 2010 Hummer H3 with the I5. It ended up needing a cylinder head replacement when it was 1 year old.
 
same line they used on VW 2.5. Not sure if based on fact. To me it was internet experts chiming in without facts. We had one in a 2012 Jetta and it was very good on gas.
The VW 2.5 is a very good engine, very reliable and my sister routinely saw 37 mpg with her 2013 Jetta on the highway. She just traded the car in with 230k on it. It ran and drove fine but the MA salt was not kind to it.
