Default 1991 Honda Accord temperature gauge fluctuates

I am having problems with the temperature gauge on my Honda. I recently got the hoses replaced on my car with were associated with the radiator and engine. Lately my Accord when it is at a stop light for too long or idling in a parking lot, I have notice my temperature gauge would go up slowly. And if I put gas to the car it will normalize. I was wondering what could be the cause and how to fix it. Thanks in advance.

Check whether both fans are running when temperature begins to elevate. If not, either bad fan motor/s or fan relay/s is likely.

good luck

Check whether you have any air pockets in the cooling system from when you changed the hoses. There's an air-bleed valve on the thermostat housing because air tends to collect there.

How high does the gauge get? It's pretty normal for the gauge to go up some, before the fans trigger.

It gets up to almost over heating and but before it get there it would be time to accelerate and the gauge would go back down.

Try idling, say in a parking lot. When the temperature goes up, do BOTH the fans start running? Normally happens when the gauge gets to 60% or 70%.

The other thing to try is whether the fans work at all. The fan switch is on the thermostat housing, with a 2-wire connector. Unplug that, & jumper between the 2 wires of the connector. Key on, that should make both fans run.

If the fans run when you jumper the switch, then you should think about the switch being faulty. Get a new fan switch. If you're ready & quick with putting the new one in the hole, you can probably get away with losing only a few ounces of coolant. Bleed air out with the bleed valve, & replenish the radiator or overflow bottle.

If the fans DON'T run when you jumper the switch, then you are going to start troubleshooting the circuit and the fan motors themselves. One easy thing is use some bell wire & supply power directly from the battery posts to the fan motors to make sure the motors actually work.

I found out it was an air pocket trapped in the radiator hose. I recently got the thermostat replaced a month ago, and I guess air got into it. Once I burped my car , I idled it, and no more fluctuating. Thanks everyone for helping me out.
