Question about Acura Cars & Trucks

My Integra temp gauge goes to correct reading but as soon as I get up to speed it goes to zero - when idling it stays at correct reading - the engine does not overheat and the fans are working OK - is it the sending unit that is faulty

Its a big possibility that it is the sender unit and/or connection to it

Check rad fan is operating. It should be coming on when temperature reaches normal operating temperature. Possibly fan shot or relay to fan is malfunctioning.

When the engine is "over heating" are the radiator cooling fans running on high speed?

SOURCE: engine overheats while driving approx 20 mins -

Check to see that the electric fan is coming on, there are two fans on this vehicle. The sender for the fan is right in front of the engine near the water housing, and is a common problem. Good Luck.

1996 jeep cherokee temp gauge reads hot 10 mins. after start-up


If you have a viscous fan hub then have it replaced as it is not drawing air through the radiator at idle or slow speed (crawling traffic). Check that are no air locks in the system as they will cause heating problems.

I replaced my water pump in my 1999 gmc yukon my check gauge light stayed on and temp gauge stayed over to hot side. can i reset it?


Not exactly.
The check gauge warning light is on because the temp gauge is reading hot.
Does the temp gauge read hot as soon as you turn the key switch on, or not until the engine as run for a few minutes ?
If it reads hot without the engine being started, there may be a short in the wiring or the sensor may have failed.

Oil pressure gauge drops to zero sometimes when idling. When gas is pressed to move the needle goes back up. It does not do it all the time


Could be the sending unit or an actual problem with the engine.
The oil pressure will be lower at idle than at road speed but should stay above 20psi.

I had an awful Ford that did that. The fuel gauge stayed up showing the crooks how much diesel was in the tank and the temp and oil gauge stayed on the last reading but returned to zero when the ignition was switched on when cold.

Volvo 240 temp gauge and rough idle


Check the wiring from the connector at the center of the firewall to the engine. Many 83/84 240's had problems with the insulation crumbling and the wires shorting out. These problems got worse when this harness was disturbed in any way. Let me know if this helps or if you need further info.

Intermitant temperature


Check to make sure your thermostat works right by monitoring the warming up of your engine. With a completely cold engine, start and run the engine for a few minutes, then put your hand on the top radiator hose to monitor if and when it gets warm as the thermostat opens more and more and note the gauge reading( if it works) the top radiator hose should be unbearably hot within 5-8 minutes. If the therm. opens right it should close right aswell, staying open a little while eventhough the radiator may have cooled may be what you are experiencing causing the rapid cooling and is nothing to worry about. The Hose should not get warm very soon after starting the engine. Regarding you gauge, lets take one step at a time, verify proper op. or the therm.
