Oil pressure sending unit, or depending on the year it might be the computer as well. If it runs ok and doesnt make a whole bunch of noise and bang and rattle then its fine to drive to the shop to get it fixed.
With the thermostat.
my gas gauge is not working what could be the problem
belt is stretched buy new one( serp. or single alt.).
If the temperature gauge is not working, one thing it could be besides the gauge itself is a blown fuse. Another possibility is a loose or broken wire on the gauge.Ê
Could be temperature sensor Could be gauge
On a 2000 Isuzu Trooper, the oil pressure indicator is typically located on the instrument cluster, which is directly in front of the driver. It usually appears as a warning light with an oil can icon. Additionally, the oil pressure switch is located on the engine block, which sends information to the gauge or light in the dashboard. If you have concerns about oil pressure, it's advisable to check both the indicator and the oil levels.
There are several reasons why a gas gauge could stop working. A short in the wire from the sending unit could be the culprit. The computer that controls the dashboard gauges could be going out.
A faulty temperature sensor, a wiring issue, or a blown fuse could cause a temperature gauge to stop working. It could also be due to a malfunction in the gauge itself.
If it's a heavy gauge (around 8 AWG IIRC), that's the charge wire to the alternator BATT post. The larger cable (about 4 AWG) goes to the starter.
In a 1995 Isuzu Rodeo pickup, the blinkers, gas gauge, and temperature gauge may stop working due to a blown fuse, faulty wiring, or a malfunctioning instrument cluster. A common issue is a blown fuse in the fuse box that controls these components. Additionally, a failed ground connection or a problem with the vehicle's main wiring harness can disrupt the electrical flow. It's advisable to check the fuses first, followed by inspecting wiring and connections.
To charge the air conditioning system in a 2001 Isuzu Trooper, first, locate the low-pressure service port, which is usually found on the larger diameter tubing between the compressor and the evaporator. Connect a refrigerant charging kit to the port, ensuring the gauge is set to the appropriate pressure for the refrigerant type used (typically R-134a). Start the engine and the A/C system, then slowly add refrigerant while monitoring the gauge until the correct pressure is reached. Always wear safety equipment and consider having the system checked for leaks beforehand.
