Why does the oil pressure gauge read higher in cold weather?
Why does the oil pressure gauge read higher in cold weather?
When checking the oil pressure gauge, keep in mind that the pressure reads higher in cold weather due to the higher thickness (also known as viscosity) of the oil. The inner workings of an oil pressure gauge depends in large part on the type: electric or mechanical.
What’s the temp inside a car on a 70 degree day?
After an hour, the temperature in your vehicle can rise to over forty degrees higher than the outside temperature. On a 70° day, that’s an eye-watering 110° inside your car! In fact, the temperature inside your car or van can rise to almost 20°F in just ten minutes.
Where is the ohm meter on a Chevy Silverado?
Check the continuity of the wire with an ohm meter (terminal 85 at the relay to the other end at the PCM terminal number 43 dark green and white tracer) on the C2 connector of the computer. With the relay installed half way, add a good ground wire to terminal 85 to see if it will engage the compressor clutch.
What is the diagnostic code for bad throttle position sensor?
Using a code reader, you should be able to confirm whether a faulty TPS is the culprit or a different component. Diagnostic trouble codes P0120, P0121, P0122, P0123, and P0124 are what will commonly appear. The engine can stall for no reason and without any warning. This happens when the TPS gives incorrect information to the ECM.
What should the temp be on my GMC Truck?
After getting it back from having leaking intake gasket replaced, the temp would go up to 260 before it went back to 170 and then would sit for a little bit, go back to 210, back to 170, back to 245 or so, then back to 170, but It never seemed to run hot. I changed the thermostat with a brand new 190* from NAPA and it seemed to cure a little of it.
How to troubleshoot a temperature gauge in a car?
Temperature gauge troubleshooting begins with isolating the problem either to the gauge, sending unit, fuse or wiring. As with any electrical troubleshooting it is best to check all wiring connections are clean, tight and free of corrosion. The following process must be preformed with the ignition key turned to the “on” position.
How can I tell if my coolant temperature sensor is working?
There are many ways you can tell if your engine’s temps are shooting up. If your coolant temperature sensor isn’t working efficiently, your Check Engine Light usually warns you of the hazardous heat that’s affecting your vehicle. A defective sensor can also produce black smoke from the exhaust pipe, since more gas is being used than necessary.
