Question about 1997 Chevrolet Tahoe

2 Answers

My '97 Tahoe overheated and now it won't start

I was driving home from the office in my '97 Tahoe. It was a cold day and I noticed the heater wasn't getting warm, I also noticed that the temperature gage was up to about 3/4. I slipped into neutral and coasted and the temperature started coming down and the heater started working. I nursed the car home for about 2 miles. I opened the hood when I got home and the engine seemed normal, definitely not overheated, no creaking or hissing. Next day it wouldn't start. Any suggestions what's wrong with it would be appreciated.

    Run some tests, see if it has spark and fuel pressure, you need to do this before we can help. also test the systems computer for trouble codes.

Overheating conditions are caused by lack of flow and/or coolant loss. you say the engine wont start. does it "crank" when you turn key? or do you hear a solid "click" when turning key? is there coolant in radiator or overflow tank? unless it was a severe overheat its hard to connect your temp problem with a no start. please clarify a little further the first things i would suspect for the temp problem is coolant leak or stuck thermostat

Probably just low on coolant causing air pockets. Start it up with the radiator cap of and add coolant, then check to see if the water pump, intake gaskets, or coolant bypass connector on passenger front corner of the intake manifold is leaking.

Cannot diagnose or run temp. Sealer for what i believe is head blown because car wont start it cranks but sputters and kills battery?


Sounds like head gasket again, but may be more serious this time. Overheating is not something to take lightly.

Pull plugs. crank. Water come out of cylinders? Head gasket. Possible cracked block or head this time, too. I'd be looking at a replacement engine.

Overheating gage when stop & go -2004 chevy tahoe


natural for engine temp to rise in Traffic - Until Themostat opens ) cooling fan sensor kicks on fan . But Antifreeze is not just a Cold weather item . Coolant is Absolutely Necessary for Hot Days . You must be full to recovery bottle setting of cold when checked prior to start up . Coolant for your make / model is Reddish - Pink colour and should have a reading of -25 thats negative 25 degrees the Lower the Better even - 50 .. Why ?? - 50 is 50 %% antifreeze / Coolant Concentrate MIX Gives Hot weather cooling Ability or very cold weather starting / winter HEAT .

My 2003 chevy tahoe won't start in the morning


Many possible causes....Too little info to make an intelligent suggestion. Try charging the problem vehicle's battery with jumper cables for 2 minutes with the supply vehicle running at fast idle (or about 1500-2000 RPM, if it is tachometer equipped) before you try to crank the problem vehicle on a cold morning. If it starts right up, you likely have a weak battery that needs replacing.

Have a '94 S-10 Blazer Tahoe 4X4 and it starts


My suspicion is a starter going bad. Sometimes when starters get old and worn they will start good when the engine is cold but not when the engine is warmed up. Did you perhaps notice that lately is seemed to drag when you tried starting, especially warm or it seemed to crank a little slower? I'd replace the starter. Hope this helps.
