>>problems after my coolent change HI GUYS I HAV A 99 Z28 and i was changin my coolent today to the green stuff cuz i jus hate dex cool it sucks and turns into chunks of brown stuff, so i flushed out my entire system and then changed my thermostat (stock temp on thermostat) and turned on the heater to flush out the heater core too and after filling up the new coolent i ran the car and added coolent then noticed my fans came on i looked at my temp it it was over 210 degees and then it went to the second white line after to 210 and then i shut it off, can u guys help me figure out wats wrong i need my car tomarow for work, im still confused i dont think i did anything wrong thanks guys
Sounds like the thermostat is stuck. Mine did the same thing when I changed the cam, but it seems like it un-stuck itself right after I reved it up for the first time. I used dexcool though. GM might have recommended dexcool for a reason.

well dex coool! i had many problems with that, if seen many gm cars with clogged radiators because of dex cool, and dex cool also causes corosion because of all the chemicals mixed inside, after a year or two dex cool will start to turn into chunks of brown stuff in your cooling system.

But ya, remove/replace the t-stat and try it. Or maybe something else has clogged it up.
