Edit - I updated this first post on 8/2/10 to reflect the additional info collected so far.

Thanks for the help and feel free to offer further corrections or info.

On another site someone was just asking about the correct color for the motor in a truck kit, this got me thinking it is a pretty common question and since there is a fairly limited number of truck engines available in kits or resin it could be handy to make up a list of the colors so we have the info in one place.

Allis Chalmers - Plum Crazy Purple

Caterpillar

3406 - New Cat Yellow

3208 - New Cat Yellow

Cummins

NHC250 - Cummins Beige

NTA370 - Cummins Beige

NTC350 - Cummins Beige

N14 - Black (may have red valve covers)

8V71 - DD Alpine Green

12V71 - DD Alpine Green or Silver

Exceptions, some truck manufacturer's use their own colors instead of the engine builders color

Ford - Black until 1965, Ford Blue until 1982, Ford Corporate Grey

Diamond Reo - Red

Peterbilt - White through 1984 then engine manufacturer color

Ford Blue

Fleetrite (available at International dealers)

Engine color if in a pre 1984 Peterbilt:

Detroit Diesel

Caterpillar

Cummins

Engine color would be WHITE.

There were exceptions, but before '84 white was the color that Peterbilt ordered its engines. Caterpillar was the last to stop painting them white.

It's also my understanding, although I could be wrong and I hope someone corrects me if I am, but if you are building an older International or Kenworth, they painted all engines red. As for the N14, as the former owner of one, those are black. Some, like mine, had red valve covers. Some had black ones. The red valve covers indicated it was a CELECT PLUS. I hope this helps some.

From what I understand and have seen the only N14 that had the red rocker box covers were the celect plus that were 525 hp. Under 525 hp they were black and even shaped different.

Mine was definately a CeLECT Plus. At times, I miss that engine, but mine was a 500 HP. Anyway, good luck with your quest for the right engine color

I have a first-issue Chevy Titan 90 kit and an AMT-Ertl American Lafrance pumper, both with 8V71 Detroit diesels (though some parts are slightly different for both engines). I painted both engines silver because that's what it showed on the Chevy Titan's box.

Engine color if in a pre 1984 Peterbilt:

Detroit Diesel

Caterpillar

Cummins

Oops. I have a 359 kit in progress, and I painted the Cummins engine gray. I chose this color because I thought I saw a gray one in a a GMC Astro brochure (see http://public.fotki.com/modeltrucks25thsca...tro1972-13.html. However, it appears I'm wrong.

This poses an interesting question: when did Cummins paint their engines grey? I always thought the older ones were beige, the N-14 series gloss black, and the Signature 600 & ISX red with chrome or black valve covers respectively. I sort of have a list going of engine colors by engine manufacturer, truck manufacturer, & the approximate years. It isn't all inclusive, and probably not totally accurate; but here goes!

Caterpillar (all engine models) - yellow (exceptions noted below)

Cummins (NTC-250, NTC-350, & NTA-370) - Beige (exceptions noted below)

Cummins N-14 - Gloss Black

Cummins Signature 600 - Gloss Red w/chrome valve cover

Cummins ISX - Gloss Red w/ gloss black valve cover

Ford (either Caterpillar or Ford make) - Blue (not sure about a Cummins N-14, probably black)

Detroit Diesel 6V71 & 8V71 - Alpine Green

Detroit Diesel 8V92 - Silver

Detroit Diesel 12V71 - Alpine Green or Silver

Peterbilt (all engine models from ~1950 - 1985) - white

Kenworth (all engine model from ~1950 - 1975) - white

Mack (pre-1990) - gold

Mack (current) - grey

International (all engine models) - gloss red

Well, there you have it. Hope it helps. Please feel free to post any & all corrections.

Thanks,

I used to work for an International Dealership in Cincinnati ohio and the current IH color is blue, reman/ford IH engines are black. I havent seen any IHC diesels red in our trucks. The only red engines ive seen in IHC trucks are the older gasoline engines. Thanks

I remember back in 1978 My Dad and I went to our International dealer with the instruction sheet from the Ertl Paystar 5000 mixer kit.

The chaps at International said the V8 engine should be red and not blue as the instructions said.

I thought back then Ertl were on the ball with information so I was a little suprised to be told the instructions on the engine colour were wrong.

Cheers

I have an AMT/Ertl Autocar Dump truck I am working on and it said to paint the engine white. I thought this was wrong until I saw this forum. I think it is a Cummins diesel. What about any other colors on the engine? Any specific parts not white? Thanks. Jack

I guess seeing a picture of the V-903 in a GMC Astro brochure made me want to paint it gray. But it appears I'm wrong. Oh well, I've never gone for total realism, anyways.

Actually, Peterbilt engines are white. Autocar engines should be painted the standard Cummins tan. Besides, it says nothing else here that Autocar had white-colored engines.

You saw a gray V-903? Do you remember the year? I've seen Cummins Grey tuch-up paint, but I don't know when it was used.

Now it is time to muddy up the waters on the color of engines in Peterbilts.

I have photographs and seen in person original factory installed engines that were not white.

A 359 with a tan Cummins, a 352 with a Yellow Cat and a green 8v71.

In one of the Peterbilt brochures is a photo of a sea of white engines behind the factory with a handful of

green and tan mixed in.

Those colours Tim mentions above are the only colours I have ever seen for trucks.

I have never seen a white Cummins or a white coloured Cat engine for trucks. But just to be awkward I have seen a red NTC-350 Cummins. The owner painted it red during an engine rebuild.

I did ask years ago at a dealership and they told me the white colour was more suited for marine applications.

Then a couple of years later I went to a boat show and on the cat stand all the cat engines were white for marine use only.

Thanks! That's just the rationale I needed for my choice of gray paint on the Cummins NTC-350 in my 359! Why didn't I think of that reason before?

I'll try to post pics of the truck later on.
