Question about 1995 Chevrolet Beretta

Intermediant high temp on gauge

My 3.1 in a 1995 Beretta temp. gauge goes almost to 3/4 for a few seconds and returns to 1/2 for a short period and then returns to 3/4. I drive on the open highway to work and it does this for 25 miles. the fan never comes on and it never boils. I thought it might be a thermostat but this made no differance.

Same thing happened to my beretta. its the heater core. they had to take out the entire dash to get to it. cost about $400 if u dont do it yourself. i had my fan fixed first and realized it wasnt the problem. i had to carry around a few gallons of water before i got it fixed or my car would overheat.

hope this helps

Thats caused by air in the system ... you have bled out the air..... on top of motor passenger side you will see a black tube ...on top of it what looks like a small bolt head thats the bledder...open it untill intill antifreeze comes out. you might have to do a couple times to get all the air out..be careful if engine is hot...this should take care of the problem.....hope this helps......

This is an indication the radiator system is LOW ON COOLANT !!!!!!!!!!!!!
However I see you might have already changed the thermostat, so next you need to change the temp sending unit located somewhere in the block or intake manifold.

With vehicle cold I put it in gear and go maybe 100' and temp gauge is topped out. When I stop the temp returns to normal in 3 seconds.


the temp gauge sends the power from the gauge to the sender unit which is a variable ground. That means that as the coolant heats up , the resistance in the sender is decreased and the current through the gage increases ans so the needle goes up
when that wire is shorting out some where the gauge will go to hot and when that short is removed the needle comes back down to cold
so that means that you will need to trace the wire along for where it is rubbed through or get an accredited auto electrician in to find the fault

The dealer updated the thermostat housing assemble, water pump, and intermediate tube. The coolant in the car does not seem to cirulate properly.


Air pockets will cause the temp gauge to spike high, then go back down after a few seconds. Why do you think it is not circulating?

It sounds like your thermostat is sticking. You can tell when it sticks when your temp gauge spikes high and your blower won't blow heat and when it finally opens your temp gauge goes back down and you have heat again.

Gas smell when starting and small dripage when back up from under engine


It sounds like the return fuel line is leaking. There are two fuel line and one is the high pressure line which goes to the fuel pressure regulator then to the fuel rails. There is then a return line from the fuel rail to the gas tank.
With the amount of fuel leak, it's going to be the return line since it's not that bad compared to the high pressure side. Follow the fuel lines from the drivers side around the steering shaft to the engine. The high side and low side (return) run side by side and you should see it leaking when the engine is running.
Good luck and hope this helps.

Temp gauge stay on cold.


Switch ig. on, ground the sender unit wire for about 3 seconds see if the temp. gauge moves, if so change sender unit, if not then it is a faulty gauge reader.

The car is not overheating if the temp gauge goes up and down by turning the lights on and off.  The gauge is giving you bad information.   You can confirm this by starting the car from cold, sitting in the driveway, let the temp go to somewhere BEFORE normal operating temp, then turn on headlights and fan blower on high, watch the gauge, then turn them off.   If the gauge moves significantly from the electrical load, you probably have a short or a bad ground connection.  

You have a short circuit or bad wiring somewhere in the front half of the car.  I don't know what thermostat switch you have replaced ... but it's not the problem .. stop buying them.  
If you are the original owner, was there an accident that may have damaged some wiring?  If you bought the car second hand,  get a carfax and find out where the thing was hit ... concentrate your wiring trouble shooting in that area.

I think it is something OTHER than the temperature sending unit or the gauge
