Hi i have isuzu npr 2010 and have overheat problem if motor work slow not have problem but during the presser working have overheat problem if stop and motor work slow become normal


If I'm understanding u right, u overheat when the AC is not on?! If so, it sounds like the electrical fan for the AC is working & the electric, radiator cooling fan is not operating. This may be caused by a bad fan switch, coolant sensor fan relay, electrical short to the fan or it may be a simple fuse. Good Luck

Cooling fans work then dont


Possibly faulty cooling fan relay... the fan has an override when the A/C comes on. (Wouldn't be a faulty temperature sensor, or the fan would work when overheating.)

Car overheat when first run turn car off and back on and car run cool


You might need to replace fan assembly and/or thermostat. Mine was overheating only when stopped at traffic lights. Only one fan was working and would cause the car to overheat. Working great after fan swap.

Overheating of graphics card while playing games


  • Clogged fan

The main device responsible for maintaining a constant temperature of your video card is the fan present in the processor. If this isn't functioning efficiently it's quite obvious that it would result in your video card overheating. If you don't regularly clean your computer, it could be highly likely that your fan is clogged with dust.

This is one of the simplest causes of your video card overheating which can be fixed by simply cleaning your fan, preferably using a blower.

  • Broken fan

A follow up of the previous point, in some cases your fan maybe malfunctioning or stopped working altogether. This could simply be diagnosed by switching on your computer with its cover open and checking if the fan is functioning. If it doesn't happen to be working, you have your answer.

  • Overclocking

Pushing your CPU to its limits by overclocking can cause your video card to overheat. This can seem fairly obvious too as if you find your video card overheating and if you've recently overclocked your CPU, it would explain it.

  • Faulty Drivers

This is a rare cause, but depending on your video card's brand a badly developed driver could also cause your video card to overheat. If you use an unusual video card with questionable reputation this could be the issue.

  • Inefficient Airflow

While your fan maybe perfectly in tact and working, the location of your fan also matters. If there isn't sufficient air flow to your video card it can also cause it to overheat.

Those are typically the 5 main reasons to your video card overheating. If you have any other points in your mind, feel free to share them below.

Fans dont work and overheats 94 toyota tercel


Most systems work pretty much the same. First check the fans themselves by hot wiring them to the battery. If they work, you need to check the engine temp sensor (some vehicles use one for gauge and fans, others use a separate one for fans) relay, and of course any fuses.
You will help yourself a lot by getting either a chilton or haynes manual to show you how to do testing.
