Opinions about New Chev 5.3L SFI motor?


I am thinking of getting a new Colorado for my truck (my 02 Dakota is getting to the point where maintenance/repair costs are excessive) and am eyeballing the Colorado. My "must have" list includes:

  • V8 motor
  • 4 doors (crew cab)

I know (now - didn't when I bought it new) that the ChryCo 4.7L V8 has expensive issues when it gets old, and am looking to avoid future problems with my next truck.

Looking for advice about the Chev 5.3L motor, please.

Thanks,

Dave

Dave, don't know if this is the 5.3 thats in my 010 Suburban, but I'm really happy with it so far. Has the engine management system that cuts it back to 4 cyl on hwy. I thought the Colorado's had that 5cyl ??? Engine. The burban gets great fuel mi. on hwy, not bad in town [has 3:08's special order] & 6 spd. auto & more than enough "balls" when you hit the "loud" pedal!!!!

        I thought I was current  but now I is smarter     I would still suggest to Dave to price out a 4 door Silverado with 4.8   I think he would enjoy the room and the better fuel mileage..   just my thoughts   The Dakota was/is bigger than a Colorado

A 300hp 5speed Colorado should be quite impressive and FUN.

I dissagree on 4.8, my 01 Chevy P/up had the 4.8 & got good mileage, low 20's on Hwy. all depends on the rr. gears & how you drive it. 01 had 3:42's back there, good tow vehicle & comfortable, BUT not as nice as the "BURBAN"

avoid the colorado/canyon, isuzu engine and built

seen a few with burnt or poor seating valves, not nice to repair

5.3 is a very good engine

my last '99 had 360k with no issuses, my current '03 has 266k, no issuses.

i see alot of them, the odd water pump gasket leak and broken ex manifold bolts.

 if you want a crew cab dave, go with a 1500 chev or gmc.

the 5.3 for the canyons in the last few years do not have the fuel management system and are detuned dogs. You can get them retuned to wake them up. I wanted an 08 but ended up with the full size. It was cheaper with rebates then the small truck and more options. For 2012 the 5.3 will only come in the crew cab model and not the extended cab. You will also have to order leather. I checked a month ago to see what was left over from the 2011. There was only 2 crew cabs with 4x4 in Ontario left but a bunch of extended cab and crew cab 4x2 trucks. Stickers on the windows of the full size show the 4.8 at 25 MPG and the 5.3 at 30 MPG. Figure that one out. I took my 08 {5.3}with only 253 kms on it towing a car 3300km round trip and was surprised to get great gas mileage. I still like the size of the small truck better but dollar for dollar go big.

5.3 comes with the engine management system [cuts back to 4 cyl. on Hwy. & also has the 6spd Auto tranny] My "burb" w/3:o8's @ 70MPH is only turning 1500 RPM!!!! The old 01 P/up with 4.8 & 4spd O/D[ 3:42's] was turning 2100RPM & still got 24 MPG Hwy [2Wd] Can't complain at either ones mileage!! for a "BIG" vehicle!! IMO

Well it seems that Colorados are very hard to find. I went to the local Chevy dealer yesterday afternoon, and there was only one on the lot, a 'work truck' 2 door 4 cyl., but by looking at it I could see that, now that I have gotten used to my Dakota, the little Chevy truck (even if I could find a 4-door) will be just too small. So I looked at the Silverado. I could get used to that, it does not seem that much bigger, when sitting inside it (although I know it is considerably larger). They sell a package down here, the 'Florida Edition' which includes the 5.3, HD towing package, and some other stuff, seems like a good choice, rebate is over $4500, and he can even find me one exactly like I want it (4 door crew cab, short bed, red paint, 60/40 cloth front seat, no other options except the 'Florida Edition') - but their first total price was too high, they lowballed the trade-in for my Dakota (which needs paint - the ChryCo factory paint does not hold up in the Florida sun), so we will just let them stew a while and see what they come up with. The truck I want has been sitting in some other dealer's lot since January, and I have blue book price to show them which is about $2000 more than they offered for my Dakota, so I have a few 'back at you' points when they call.

We'll see.

Or maybe I'll just paint my old truck, keep it until it falls completely apart, it only has 58000 miles on it and it only gets driven about 40 miles a week nowadays ...

Although it REALLY aggravates me that another one (this makes 3 out of 4) of the power windows died, the glass just falls down inside the door and the only fix is to install a whole new motor for $275 grrrrrrrrr - until I decide what to do, duct tape is holding it up, with the crappy paint I look like a true redneck hillbilly driving it now, eh?

Dave check at a NAPA or some other parts store for a complete regulator assembly. Dorman gives a life time warranty on their power window regulaors and they cost out about $125.

We have a 5.3 in our 2000 silverado 4x4 short box regular cab step side. The only issue with the engine was a water pump at 125,000 K's. At present there is a slight hesitation when starting up cold and not letting the engine warm up before leaving.There is no engine light on to check for a code reading so I am thinking it may be a dirty injector.

Has your Dakota aways been a Florida vehicle? At 58,000 miles, it's just getting broken-in.

What I really want from the 5.3 is more guts, and hopefully less problems down the road

I think I will go look at the GMC Sierra, maybe they will be a little hungrier than the Chevy guys, eh?

yes they both get good gas millage on the open road but if you drive it short trips the gas millage is poor, not everybody drives the open every day.
