My 2004 3400 closed system ,runs hot in town unless heater is on. driving up a mountain pass it gets very hot.on a flat highway runs normal. new t state,resivior cap, both fans work no leaks or smell


Radiator fan motor or radiator fan thermostat defective/

Also there is a relay that operates the fan motor

In town not enough air passing through radiator allowing it to over temp.. With heater fan running acts like cooling fan keeping engine cool

Highway driving ample air passing through radiator without fan.

Hill climbing requires cooling fan/

Hope this helps?

Why does my 98 dodge caravan have trouble climbing hills?


A transmission issue would give vibration tremendously during uphill. If you're not getting the vibration, or burning smell of transmission fluid, suspect clogged catalytic converters.

Power loss in range rover p38 4.6 lt when going up hill


the p38 is a bit sluggish and slow on long steep hills, really not geared for performance but more as a piece of heavy equipment. strong horsepower wise very formidable powertrain but you're not going to have that get up and go that many drivers look for. couple quick suggestions you may want to check your plugs and wires a common weak spot in the ignition system, and i might suggest also running i can of seafoam through your engine. you deposit in your gas tank runs through with the half a tank of gas. i'm not a big advocate of fuel additives or octane boosters but in the case of seafoam it's definitely a worthwhile and proven product. don't forget also your sport mode button down next to your shift lever push that button down and it keeps your transmission from overdrive so you can accelerate into freeway traffic and climb hills without your transmission shifting

Sounds as though your engine management chip maybe beginning to die. I should get it checked professionally. If it is the chip, it will cost you a packet to rplace.
