Caterpillar Diesel

If you gather your input from internet forums, you only hear the bad stories. The thousands of Folks who are happy with no problems don't feel the need to go post on a forum.
I have a 2005 C7 that's been flawless and very reliable. There were a few initial issues mainly caused by Freightliner the chassis builder, but were easily worked out.

I guess most of the problems have been with the mid-2000 models, C7 and others. Most of the complaints have been with the fans seizing, fuel pumps going bad, blown head gaskets and other problems.

I haven't seen any problems on earlier models and very few people have posted as Dolan did, no problems.

Just wondering if it was a short period where the problems came from and then the problems were fixed. Thanks again.

I have a C7 since 05, no problems, not one. I have never heard of any problems.

We have a 10-liter Caterpillar in our coach. We have almost 160k miles on it. The only issues were a burst hydraulic hose, and recently we had a corroded fuse holder going to the engine ECM that caused a shutdown. Easily fixed once the Cat shop found it. The engine purrs like a Cat (;)) and doesn't hardly use oil at all.

I have a C7, have had zero issues with it. My BIL has a C7 in his rig and has had zero issues with his, so we must be exceptions? I would not hesitate to buy a rig with a Cat C7 again, or any Cat, Cummins, or Detroit, they are all good motors and have their strong and weak points. I keep in mind when reading the forums folks don't usually post I went out this morning, drove it and everything worked. When folks have issues you don't know if they drove it like they stole it, serviced it regularly or not.

I have a CAT 350HP in my 2006 coach. No problems, runs great, easy start, good pulling power in the mountains.:) It has app. 33K miles and get service yearly by Freightliner at Gaffney SC

Yeah, you might be right if the ones you're looking at have more than 500,000 miles....anything less than that you should be good to go.

Joking aside they are awfully good engines although I've heard some reports that the ACERT models had a few problems. I sure do like our 425 hp C-12.

I've had 2 cat's with the 330hp. Only issue was an AC compressor seizing up. Have put around 80k miles between the 2 and that was it.

That is a very general statement. Just what problems have you read about and which engines?
