Thread: 2009 Colorado Engine Problem

My mate has a 3.0L 4x4 Holden Colorado 2009, Common Rail. When he accelerates with foot to the floor from low revs it blows smoke and can hear a very distinctive knocking noise coming from the engine, it's fine once the revs are 3K+ but is very noticeable even during ordinary driving. It's also noticeably down on power.

I was thinking injector problem?

Any ideas?

Get the injectors checked. Also, anything knocking is generally getting rooted when it comes to engines. Fix it sooner rather than later and the pocket will thank thee. Also, mates don't let mates buy colorados, or rangers.

What would they cost to replace? Ballpark.

No idea, probably get em overhauled rather than replaced. I'm not a diesel guy really, @northdude may know? Give Alltech diesel and turbo on the shore a yodel to get a ballpark figure perhaps. I have a guy Matt who does injector pumps and stuff for me and for mates' homers, I'll give him a ring tomorrow to see if he's played with those before.

They (common rail ) knock because they do small injection pulses before tdc
When injectors get worn these pulses are not controlled as they should be,
So more fuel before compression ignites and slaps the piston making a knock,
And yes all you Toyota lovers that rattling you hear on acceleration is rooted injectors

Most injectors are around 3-350 each, will need programming aswell

And an egr clean out, depending on kms could be a inlet manifold off job too

Gota love nice powerful common rail engines

If you put a "F" in front of Ranger you get a "Franger" which also goes around a penis.

I'd buy a Ranger if I could afford one, seem to be pick of the bunch really, from what little I know/have heard.

It's done 220,000k.

Savage I had this with my 2009 Colorado they are Bosch injectors I think, bosch can refurbish the injectors, it is call the TOYOTA modification, your Holden dealer can sort it. Probably dirty fuel, does he use BP? No probs after the TOYOTA fix

I'd rather drive a Franger than a Toyota, any day!

My girl friend got that problem on her Colorado. Quoted 4k$ at the Holden dealership, the local diesel mechanic fixed it for $3.6k.

I think mine was about 4 k but done under warranty, after 4 months of negotiation, and changing of many parts before resolution, Injectors!

Oh dear. Can you get counselling for that yet. It ll be on a list someplace hang in there !!Toyota hater recommending a Toyota fix for a Colorado. Double meaning right there. Lol
4 k repair that's screaming for a new engine combo. Should fit a Toyota mtr to it

$4k ouch, maybe the cheeky $10k I offered him for it wasn't as far off of the mark as I thought.
