How do you make a c12 work in a truck it was never intended for?

It can be done but is it worth the time and money. All the modifications that needs to be done on the electronic side & mechanical side. You have to "weigh" out the cost. I do believe it would be cost effective to just overhaul your paccar or buy a truck with a C12. All the best to you.

 

Kick me a PM later. Im getting ready to do a very simular swap save with a C15 and have done a lot of the groundwork. Ill kick names, numbers, quotes and such to ya

 

Not so much honestly, with a full emissions rebuild as well your looking at a simular cost as a swap. If you do just the engine the average quotes from several dealers and non dealers is 48-50K for an out of frame 35-45 for inframe. With emissions add 10 to 60k depending on whats borked. Engine swap is abkut 65K all in. +/- 5k for labor

 

Do you really believe that replacing an emissions system costs 60k, or are you just being dramatic because you don't like them?

 

Why would anybody spend 70 grand to put a C12 in a truck? That’s madness.

 

As i said it depends on exactly what is broken. If it just needs new sensors doser sensors ect your likely going to be a few thousand at most for example. However if say if your SCR, dpf filter and harness are bad suddenly your looking at an easy 10-20K if the whole system is borked and needs a ton of diagnostics then you keep going up and up.

As for the cost i KNOW that its 60K when my SCR literally MELTED it took almost the entire system with it. Kenworth, peterbilt, and 4 diffrent indys wanted a minimum of $45,000 to repair it. And this was just at the start of covid. Many of these same parts are quite a bit more now. These are the only pictures on my phone atm the rest are in my documents box as its been about a hear now. Also this was of the cheapest quote i got at the time for the DPF filter only. The SCR was almost $7500. Granted if i use junkyard parts or off brand ones which are at best iffy on quality i can get them vastly cheaper but.....well do you really trust chinese junk on your rig?



But hay you folks seem to think im a liar dispite giving you plenty of proof and because i dont use junkyard parts or off brand junk i guess im just playing up drama right?

Oh and just to be 100% absolutely clear here so no one tries putting words in my mouth again. That $45K was using USED PARTS if i wanted NEW paccar parts i was looking at close to $75,000 since it took the ENTIRE system with it. And i do mean the ENTIRE system since when it melted it caused a bunch of shorts that broke a ton of stuff as well as caused a massive amount of heat damage.

As for chinese cheap parts, please see my new owner thread for how that chinese turbo worked out. No thanks.

 

For a C12 sure i can agree there i should have been clear the 70k is for a C15 fresh from factory. And easy for many O/Os we know the frame, cab, wireing ect is good but the engine is junk. Put a new engine in and you just gave your truck several years of life for a much lower sum then a new truck and got away from emissions systems and a 3+ year warranty atop that if you buy factory new/rebuilt. If you want to go junkyard or 3rd party you can get engines quite a bit cheaper.

In this case you can get a C12 for $6500 https://www.truckpaper.com/listings/truck-trailer-attachment/for-sale/30516935/2001-cat-c12 i admit that suprised me as i ASSUMED they would be close to C15s so that is infact my screwup there. Assumeing the drop in price is still the same 10k for labor and a conversion kit is also still about $10k using that engine you can ditch your emissions system and do a new engine for around lets call it $30K to round up. Call it 40K if you rebuild the engine first with a platinium rebuild kit which are going for 8kish.

 

I've replaced and priced everything emissions related on my truck over the past 6 years. I know what it costs and the labor involved, especially since I've done a lot of the work myself. There is no way I could see myself spending much more than 30k (US dollars) on emissions parts and labor using OEM parts and shop rates, even if somehow I needed to replace everything at once. Maybe you have a gold plated emissions system or something. Maybe you're easily swindled. 60k is not even remotely near the upper end of what it would cost me. If you're getting a rebuild, you can't even add injectors or turbo to the list of emissions components unless you like replacing parts twice.

So yes, it looks to me like you're just being dramatic.

 

I didn’t know engines were the only thing that wore out. It’s good to know that all I have to do is replace the engine and I get several more years of life out of a truck.
