Bought a 2004 Hemi Ram, performing all necessary maintenance

Hey guys, first post here. We bought a truck for my wife, a nice 2004 Ram 1500 Laramie 4WD. Its got 100,000 miles, and we are the third owners; it's always been a southern truck, so no rust.

This is the third Hemi between the two of us, I had a 2007 Magnum RT that wooed me away from the LS world, I bought a 2015 Charger RT Scat Pack this year, and now her Ram.

The Hemis seem like very strong, reliable engines, but I'm not as knowledgeable on them as I was the LS engines. I have pretty good grasp of what's going on though.

My wife loves her truck, she named it and everything. I want to keep it running and looking good, so since we got it this summer it's gotten four new tires, an oil change with Rotella T6 synthetic, a transmission flush/filter change, new factory plugs and MSD wires, and a K&N cai. As far as I can tell the truck had a muffler but was stock otherwise.

What else can I do to extend the life of the engine and drive train?

I'd love to put a catch can on, but it seems 04 used an internal pcv set up. I plan on a full front/rear/center diff fluid change, and possibly a radiator fluid flush.

Are there any problems I should be aware of for this year? Should I be rebuilding the heads, or looking into replacing anything? It runs great.

I've right about getting a tuner for some extra torque, even though the truck runs great. I'd love to eventually get a set of long tubes on there, but that's for another post.

Welcome to the forum, the 03/04 had on a few trucks a valve spring problem. Folks who are concerned about it often just replace them with 6.1 exhaust valves. This can be done with the heads on. I didn't bother with it until my first cam change. When playing or passing it is advised to turn off your overdrive. Good luck..

That's the problem, there's no way of knowing in advance. They break at a stop light as often as I've heard at wot. I believe it was a rare event but there was some that broke springs. I would turn mine up to 6200 up to the day I changed them without issue.

HAHAHAHAHAHAHA, man welcome to the world of Hemi trucks lol. I never have driven a LX car but with how my Hemi has treated me its gonna be hard to stray away from a hemi car when time comes for a new vehicle

I've had my truck since 19(25 now) so I'm sure my driving habits haven't helped
