RE: cooling problem
Hi i have seen more than my share of t stats that are bad outta the box, easy check is if car is hot grab top radiator hose and see if it feels hard, if it is t stats not opening wich would over heat. next is ur fan relay could be getting a bit off calibration coming on too late. another is air lock in system vettes are notorious for that. few tips may help ya.

yeah bleeding system is like removing all trapped air in the systems high point. leave rad cap loose to start kust turn it so its on but not all the way,theres a half way spot u can feel. then run motorwhen its almost warmed up turn your heater on full blast,this will purge the heater hose lines.after than let cool. remove cap check and fill level replace cap fully,run to temp and open heater up full blast again. vettes like to run around 212 to 220 i think there are some egr sensors that require high temp to operate.

RE: cooling problem
I have a 1985 and have the same problem of temperature abaove 200. I have a 160 but can not maintain cooler temperatures. I have had other vetts with big blocks without any problems. I will be concentrating on the rad/condensor for blockage. Don't forget that the air is brought in form the street and any object could be sucked in. Other factors to concider is the temp of the trans which is also cooled by the rad. Will let you know my progress.

RE: cooling problem
After a couple of tries and each time being able to and more coolant each time I successfully removed the lock. My front spoiler was really effed up, so I ordered a new one, my head must have been in another place case the one that I had on there wasn't doing any thing, it was all busted up, didn't realize that it so important, thanks for all you help.

RE: cooling problem
Thanks for the info. The vet is back together. Things I did. Replaced water pump only because I did not know the age of it(why take a chance). Cleaned out between the condensor and the rad, preasure wash rad and still could not remove all the little stones. Today was 90 degrees her in Virginia Beach and the engine temp. stayed below 190 with a 160 thermostat. Will be trying some addatives to see if I can get it cooler.
