SOURCE: 2000 chevy silverado normal operating temp 210 ,

With the truck running at operating temperature, squeeze your upper radiator hose. You may have to check it a couple times allowing time for your thermostat to open. Are you able to compress the hose a little when you squeeze it or does it remain stiff/solid? Your thermostat may be stuck open or even stuck closed.

Sounds to me like the Throttle Position Sensor. Thats usually what makes the throttle "rev" But that is not going to make the oil pressure drop. Pull the codes from your car and look them up online. sometimes there is an extra fuse u can add to your panel and turn the key on and it will flash your codes via the check engine light. i.e. if the light flashes 2 times then small pause then 1 time and long pause that is code 21. if there isnt a extra fuse you can usually jump it with a paperclip and pull the codes. not really sure how to do that with yours. but im positive Google knows ;)

SOURCE: 2002 monte carlo fuel gauge doesnt work,pump works ok.

It is likely the fuel level sending unit. I had a customer with an 03 Monte Carlo that the pump went out and the fuel gauge hadn't worked in about a year. We replaced the fuel pump module and it took care of both problems. I believe the sending unit is available separately from the complete module.

How bleed coolant line on a 2005 chevy avalanche


You need to start this when it's cool not hot take your radiator cap off start the engine start adding water into the radiator keep checking it with your finger and keep adding when the water turns warm to the touch keep adding water if it's taking it and squeeze your upper radiator hose continuously to burp out the air keep adding water try that and see how it works

I have a 1999 chevy malibu , front wheel drive with a 2.4 litre twin cam engine . the car overheats and water pours out of overflow hose. what is the cause of this?


well, a lot potentially COULD be wrong. here is my list of what to check.

hoses for deterioration and sponginess, its unlikely but possible your hoses are collapsing due to poor condition and not letting water flow through it

check thermostat for proper operation ( remove thermostat, compress spring to open it insert string then suspend it in a pan of boiling water. it will fall off the spring at the aprox. temp its set at. if it is stuck closed then its your culprit)

check water pump ( hard to diagnose, some cars have a weep hole at the bottom of the water pump that drips water while running at any temp. )

check antifreeze dilution and condition, water cools better that anti-freeze 50-50 is recommended but in hotter climates 25-75 is more appropriate. also the dirtier it is the worse it cools

ensure your engine fan is operating by running the car and observing it with the hood open. at a specified temp ( 200-230 F neighborhood) it should turn on. If it doesn't then check your fuses and wiring and repair/replace as needed

finally check for a clogged radiator/ flush it. If the car was bought used or you know for a fact the radiator stop-leak pellets were used in it. you will most likely have to replace the radiator

other factors are engine timing (shouldn't be an issue for your year of car)

I hope this helps a bit

Is the engine actually over heating or just the gauge giving incorrect readings?? The stepper motor in the console's temp gauge could be defective. Have someone with a laser heat gun check the temp of the engine around the thermostat to find the correct temp.

THE TEMP GAGE FLOATS BACK AND FORTH. NEW RADIATOR,FLUSHED THE HEATER CORE, CHANGED THE THERMO STAT. WHAT NEXT? THE WATER PUMP.


#1 If It's a 2000-2006 GM the stepper motor in the cluster may be the problem.
#2 There may be air in your system. Bleed out the air and the Antifreeze flows a lot better.

Sounds like the radiator is clogged, have the cooling system flushed, the water pump pumps water into the engine and it comes out the top hose to return to the radiator to circulate through it to cool, if the radiator is clogged the water pressure will build on the top hose, also look at the bottom radiator hose, if it collapses when you rev the engine the radiator is clogged, although sometimes the bottom hoses are reinforced with wire to prevent them from collapsing so just because they do not collapse it does not mean the radiator is not clogged.

I don't think you do any thing wrong. I suspect the coolant temperature has a loosed connection, or it is bad. If you are certain that your coolant temperature sensor is good then remove the thermostat to run for 2 days to see the temp reading gauge is normal then buy a new one to put it back. Good Luck.

If the replacement thermostat is good, and installed properly, then the temp sensor might be bad. I hate to tell you ($$$$$) but waterpump could be bad (more expensive)
