Change the engine oil or top it up to the specified level if the oil is still good and not burnt. After such conditions if the engine oil level is low, it would be advisable to change it completely. Also check if water pump is able to circulate the water properly(see on removing the radiator cap while the engine is running). Clean all plugs as added safety and try...sodeep

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.

Should i bleed the thermostat to keep light from blinking for coolant

NO cooling systems do not need to be bleed they are vented into the recovery bottle . When the coolant expands when hot it goes into the recoverry system and when it cools it gets drawn back into the raitator through the hose that comes from the radiator and goes to the recovery bottle . Dose the light say ckeck gauges if so the problem is eighter with the antifreeze or the engine oil check the level of bolth . If the oil is OK and full then try flushing the cooling system . Antifreeze olny last about 5 years and chevy uses that orange antifreeze if you change it make sure the new stuff is compatable with chevy standards it should say on the container Good luck

Check gauges, the themo gauge indicates hot, open the hood and no steam of being overheated. liquid anit freeze gone.

Chevy has a problem with this . The check gauges light means its the oil or the anitfreeze . I don't know what year your vehicle is but the basic problem is the intake manifold is aluminum and the block is iron they expend and contract at differant rates so if the engine gets to hot the gasket that seals the two fails because there isn't enogh bolts holding the intake down to the block 8 total and all in the 4 corners of the block - maniflod . The problem is vary likely the intake manifold gasket check for oil in the antifreeze and antifreeze in the oil on the dip stick it will look like a white fomey residue on the stick and in the antifreeze if you take the radiator cap off you will see oil floating on the top . You can save the engine but the intake manifold gasket needs to be replaced . The olny other cause would be the engine oil being to low but in this case the engine is probably on the way out depending on what engine and what year

1999 tahoe doesnt always blow warm air it goes back and forth between warm and cold even after running on highway,temp gauge goes up while at idle

Hello: First check and see if you are low on coolant, check both the overflow tank and the radiator itself. If low put antifreeze in it the check for leak. Have unit pressure checked

Our 03' Chevy Tahoe's engine temperature gauge has been running low- typically around 180, sometimes going all the way down to 160. It used to sit conistently around 200. Any ideas why this would be...

It's quit possibly a failing gauge. It's common for them to go out on 03-06 Tahoes at around 50-80,000 miles. Check this page for more on the problem and how to get it fixed - Tahoe Gauge Repair

2004 Chevy Tahoe. Heater working only at higher speeds.

you have air trapped in the cooling system. A good indication is that one or both of your heater hoses going into the heater core are cold when they should be hot.
Park facing uphill, raise front of vehicle so radiator cap is higher than top of engine. (You want bubble to get to radiator and out the cap.)
Leave cap on but loose, so bubble can purge.
Turn heater on.
Fill radiator and reservoir with 50/50 mix of antifreeze.
Start engine and run at about 1500 roms until the engine warms up and thermostat opens.
You will know themostat opens when top radiator hose is hot indicating coolant is flowing.
Shut off engine.
Fill radiator and reservoir. Install cap.

please Rate as fixya if this works. good luck

Temperaure gauge/thermostat 2001 chevy tahoe

yes, your thermostst is sticking open or closed. it is an easy fix and the part isnt that much but you do have to drain some of the antifreeze/coolant out. when you get the thermstat pick up a repair manual for your truck and it will take you step by step.
