As long as you are running Light Truck (LT) tires, you should be just fine. Manufacturers take into account the tire pressure is going to go up due to heat buildup. This is why you check tire pressures when they are cold so you don't get a false reading on them. If you lower the pressures to 80psi when hot, you'd actually be causing your tires to overheat ...

According to this website, the cat can surely be plugged by coolant entering the catalytic converter. Here are the reasons given on the website: Engine Tune-Up Required. A number of problems could occur to the catalytic converter as the result of an engine that is out of tune. Any time an engine is operating outside proper specifications, ...

Ram Air is actually a type of engine/intake which Pontiac used in the late 60's for their GTO's. Pontiac called it a Ram Air. These were a series of engines (basically named I, II, III, IV, & V). The most recognizable part of the combination was the hood scoops. You can see them in the following images: Here is what the setup actually looked like under ...

KAM remains powered when the ignition is off due to the fact it receives power from the battery. It is the same as RAM in the sense that it is a volatile form of memory and will lose its data if power is lost, this is what makes it different to ROM which is non-volatile and does not require power to store data. The KAM stores details about vehicle usage ...

The diagnostic systems in cars get upgraded every few years. It wasn't until the early 2000's that car manufacturers really started to integrate ways of displaying diagnostic info without an OBD scanner. Typically if it is not included in the shop manual it is not a feature on that car. Your best bet is to go to the local autoparts store or shop and have ...

It is probably going to be one of your pulley wheels, but I doubt it's the pump. If it's brand new, they usually don't make any noise at all. It is either going to be one of either the idler or tensioner pulleys. And if you don't know which one is which, if you eliminate all of the other pulleys which have things attached to them, you should have one ...

From what I have seen, "Keep Alive Memory" can be cleared by removing power from the car by disconnecting the battery. ROM is "Read Only Memory" and is permanent at the chip level. Yes there are various kinds of ROM that can be rewritten but at the highest level the chip itself retains the contents and requires no power to do this. Keep Alive Memory requires ...

After an exhaustive search on the internet, I came to the conclusion that while the two heads have a different part number and are different in some very minor ways, I have just thrown the heads on there and done the deed. If there is a significant difference I couldn't see, there doesn't seem to be an issue with them. The truck started right up without any ...

The 3.7 is notorious for having a rocker arm fall off and or lifters collapsing. This is usually accompanied by a check engine light being illuminated. Use a stethoscope or a long screw driver and try to isolate where the knock is coming from. If it's coming from a valve cover, remove the valve cover and you're likely to find a rocker laying around. If ...

Basically there are a few steps you can go when you want to cram more combustible mass into the combustion chamber. The lowest step is a ram air, or cold air intake. This does not have an active device pumping more air in, it just uses the movement of the car and the pressure wave that it creates to push more air in, which causes the computer to force in ...

It doesn't have to continue vibrating. It can get to a point where the vibrations stop for a period of time, then start again at higher speeds. I would bet you just haven't gotten to the speed where it starts again (not that I'm suggesting you try to go that speed). It's just like at lower speeds you don't feel a wobble, because it hasn't gotten to the point ...

Turns out to be the transfer case chain. It was loose and just needed to be replaced.

I believe that fan has a two speed motor, three leads on it. One is low speed operation which is turned on by the AC system. The second is the warm engine connection which is high speed fan. This is controlled via a temperature switch through a relay. With this knowledge need to test and or replaced the temperature sensor and the relay that is this high ...

For your edification in case you want to try this. Here are the procedures for getting the vehicle to learn the new key. There are some disclaimers/actions you need to pay attention to, so read the entire procedure before you try to do this. If your key is a completely metal key, it will not have a chip inside of it. If it looks like the image below, it ...

Overdrive is misunderstood. The traditional definition is: a gear that drives the rear rotations to be lower than that of the crankshaft. That means you truck shouldn't go into 'overdrive' at 40mph. No car does this. At a higher speed, in order to conserve fuel, a car may go into overdrive. Knowing if your vehicle is actually going into overdrive, or ...

I'm not sure you have enough information here to go on. My best advice to you is, fix the wire and see if it fixes the problem. The wire needs to be fixed anyway, so fix it.

Coolant coming out of the overflow is a sign of over-pressurisation. The cheapest cause of this is the pressure cap failing - have you replaced that? The other main causes of it are overheating, or gas getting into the system and so increasing the pressure, usually through a head gasket breach between a cylinder and the water jacket. Have you noticed any ...

There are two things which can be wrong (that I'm aware of) with the heater core. It can be plugged (not letting coolant through), or it can leak. If blocked, there's absolutely no issue. Drive without heat. If it leaks, you'll need to run your heater hoses in a loop, to bypass the heater core. Basically, you are taking one hose from one side (either intake ...

Your not going to like the answer. Diesel is a thick oil as compared to gasoline. Fuel filters for the two are quite different. Your truck has a returnless fuel system with an integral fuel filter in the fuel pump module. The oil probably has contaminated the filer preventing normal flow of gasoline. Dropping and draining the tank will get you most of the ...

I'm pretty sure the thermostat is stuck open. The coolant/engine won't heat up fully and you'll get cool coolant through your heater core. In most vehicles (and I'm pretty sure this is how the Dodge Ram's work) the coolant goes from the engine to the heater core directly. If the engine is running cold due to an open thermostat, only cooler coolant will be ...

You should check belt tension and visually inspect the pulleys for rubber deposits. You can check pulleys by applying a load to the pulley and spinning it. You probably need to include which transfer case you have on the vehicle by looking at the stamped plate. How much vacuum is "little vacuum"? If you have a NVG231 there should be engine vacuum (roughly ...

Ram air induction does not exist in normal vehicles for all intents and purposes. Ram air induction is the forced induction of flow due to air flow being compressed (pressurized) into an inlet from the conversion of kinetic energy (velocity). Air is considered incompressible below speeds of about Mach 0.3 or 230 mph. A supercharger and turbocharger both ...

Ram air is simply air that is forced to enter a moving aperture. The 'ram air' at 0mph would effectively be non-existant, and, like aerodynamic drag, would increase exponentially with speed. The faster you are moving, the more air is being forced into your ram air inlet.

Ok, time to get serious here :-) Do you have access to a test light or a DMM (or a volt meter of any sort)? It would be good to start by looking at the evidence – if you still have the old bulb, does it look good (clear glass, with both filaments connected to their "arms" on both sides)? Are you sure you've got the right bulb? Has anything happened ...

Are you pouring the ATF down the dipstick tube? The dipstick tube has a bend in it. When you pour fluid down the tube, the fluid follows gravity and tends to run down one side of the tube and bend. The fluid doesn't all go into the transmission; a small amount clings to the sides of the tube. When you put the dipstick in, the "back side" is being wiped ...

Is the oil still leaking into the coolant reservoir ? If so then yes it will eventually affect the cooling of the internals of your car once enough oil gathers in the reservoir. If not and it's only a small amount(say a thimble full) then it won't do any damage in the long run to leave it in there although the dealer would probably recommend you flush it a ...

Headlamp housing is what you need. I'm not familiar with that particular truck, but the bracket looks like something used for aiming/adjusting the position of the housing. Typically, the housing will have direct bolts on some sides to hold it in place (what it looks like is broken), and other bolts will be adjustable somehow (which is what the bracket ...

The part you are looking for is the headlight assembly. I believe the tab which is broken on yours you can see sticking up in this image: In my humble opinion, you are going to be better off finding an aftermarket set off of eBay or Amazon which will fit your truck. This way they match exactly. You could also try a pick-a-part or junk yard for your exact ...

It sounds like you have a serious problem somewhere in your front suspension. Normally the steering is very loose because you have one or more worn out suspension components, that move out of place under the load of braking and make steering very difficult. Your power steering is probably fine, but the dislocation of the components make steering mechanically ...

As I wrote in my comment, the cable is very likely bound up. Contaminants (e.g., dirt) get inside and the cable won't return. When you release it, the system gives just enough so that the emergency brakes are not fully engaged, so that's consistent with your being able to drive it. But it could also be the brake assembly itself - on one side or even both. ...
