guys I'm really frustrated. i have a 97 z28, but she is being really moody. my temp gauge will slowly rise till it hits the red, run there for a while, quickly cool to 210 and very slowly rise back up again. when i feel my coolant line, its very soft, even when warm, my fans also will turn on and off when they feel like it. my low coolant light is on, but i assure you its not low. i already replaced the thermostat. please help

 

The low coolant light is a common problem and as long as you check the resevoir for level in addition to checking the radiator, you are probably okay for coolant level.

It sounds like you may have an air pocket in the cooling system. Checkout this link and make sure you get all the air out: 4th Gen LT1 F-body Tech Articles

 

thanks man ill try that and let you know

 

That is EXACTLY what happened to my Z. Use the method on shbox.com to bleed the system. For me, it turned out that half of my system was air...

Good luck, and don't get burnt by the superheated steam that will come out of those screws if you bleed the system hot!!!

sure sounds like your low on coolant. are you checking the radiator or the resovor? need to check the radiator. when its cooled.

 

make sure the radiator is full while bleeding it. park the car as steep a hill you have in your area, park with the front of the car on the up side. let cool, fill radiator, with the radiator cap off open the bleed screws one at a time and close them when coolant comes out. refill radiator as needed. the bleed screw on the hose will not bleed untill the car is started. soo once you have bleed the lower screws, mine has one under the tb, one on the thermostat cover and one on the hose that is next to the alternator, this is the one that will not bleed without the motor running. anyways once you have fluid coming out of the other or others then with the cap still off start the motor and bleed the hose screw till fluid comes out, check coolant level in the radiator and fill if needed and put the cap on. take the car for a ride around the block and rebleed the screws without removing the radiator cap. then let it cool and do it again from the start to see if air is still there if so repeat till you get no air on the re bleed.
