Check that the coolant is at the proper level and look for any leaks at the radiator, hoses, and water pump. Watch the engine and make sure that the cooling fans are operating properly. I would start by replacing the thermostat. If the check engine light is on, take the vehicle to an autoparts store and have them scan the computer for any faults that the computer has identified. Most parts stores will do the scan for free. Getting the codes should help narrow down the cause, if the problem is being caused by a faulty sensor. Hope this helped and best wishes.

2.5l engine, 5-speed A/T. How many miles can I go after gas light turns on?

It depends on what speed you're driving, if the terrain is hilly or flat, what the ambient temperature is. I haven't seen my low fuel light in ages. Keep in mind it isn't a good idea to run your fuel level so low. The fuel pump is cooled by the fuel (its inside the tank). Running the fuel level very low allows the pump to run above the fuel and not stay cool. I strongly suggest keeping the upper 3/4 tank full as I do. It certainly doesn't save anybody money to run a tank of fuel completely out before refueling. You may fill up more often over a given period of time but you're buying less fuel each time.

How much weight can a 1978 GMC 3500 with a 350 5.7 liter engine tow

3000 LBS fairly easy. But if your going long haul, put an external transmission cooler on it. Turn the overdrive off on hilly terrain.

My jeep 2.8 diesel uses 12 l per 100 is that high or normal

It all depends on the terrain and the driving method that is followed as a lot depends on the fuel consumption if the terrain is hilly and the traffic condition is worse. Use of AC is another factor.
You can have your fuel pump checked or calibrated for a final assessment only if you notice smoke in exhaust.... Not sure of your mileage clocked to know the state of the engine but have the scheduled maintenance done accordingly..

I have a 1995 Maxima. For in town driving is the overdrive to be on or off?

this is really not a problem, overdrive will only be used if car speed is up to speed for it to engage and that is how its designed. If you pull a trailer or if you are in a hilly area and your car keeps shifting in and out of overdrive you should turn off untill more flater terrain, otherwise it doesn't hurt your vehicle.

95 corolla has been stalling at random for the last couple of weeks. It only did it a few times then it would drive perfectly. Today I was driving in hilly terrain and it started stalling alot more than...

Check the fuel pump for pressure and volume. I had an Accord with the same symptoms. It would pump the proper volume when measured at the ground, but would not pump the fuel up high enough on the car, so it would fail on hilly sections.

Drive selector question

The d with the circle is overdrive. This is the selection you should use unless you are in a situation where it is shifting in and out of overdrive to much for example you are riding in traffic in hilly terrain at speeds around 35-45 mph and it is constantly shifting in and out of overdrive,then you would use the big D.Or if you are coming down the mountains and you want more engine braking so you don't have to use your brakes to much.

2004 dodge ram is over heating, the thermostat and fan clutch have been replaced.Doesn't(over heat) in cool weather,but will in mod. weather if driven over 70mph or hilly terrain due or increase of rpm,and...

Water pumps can stall out, but do you have air trapped in system.
Had you recently had the system "open" to replace hose, thermostat, temp sensor. Some Ford and GM have a bleeder screw on a high point in cooling system to bleed out trapped air.

Check your trans fluid color. Since the trans cooler is built into radiator (automatics)

IF the engine is overheating the trans CAN overheat
IF the trans is overheating the engine CAN overheat

They share the same cooling source and trans fluid gets hotter than oil, but yet it has a wimpy cooler built into radiator. Maybe add trans oil cooler to system.

Also outside temp affects the cool down rate of the radiator, air trying to cool down hot radiator/engine is less effecting than cool air cooling hot radiator/engine
