I recently bought a 99 chevrolet cavalier LS 2.2 from the time i drove it home it started heating up,so i replaced the thermostat filled it with anti freeze and it still guage read 195 degrees and fan never kicked in, i took it to a service tech he then bled the radiator with the cap off then cooling fan fuse under hood was okay finally after almost reaching 200 degrees fan kicked on,but would'nt turn off, he said it needed either a radiator flush or a new radiator,i manually I flushed it myself with a money saving way, it not only lowered the temp but it would cut off.finally,i had a certified tech replace the high side and low side ac lines and recharche the system everything seemed fine, ac was cooling,temperature did'nt read more than 195 degrees until I ran it on the expressway for about four miles once exiting guage shot up,i turned off the ac and pulled over i let cool for about half an hour then ckecked cooling level it took two gallons of water,i drove it and it heated up again. i opened the hood and tried the ac now the fan would 'nt even turn on when engaging the ac.so now i tried to run a test wire from the cooling fan fuse that did'nt workand last but not least i unplugged the wiring from the radiator fan ran a three foot wire touched the positive on the battery it engaged the fan, that was enough to make it home,now I need some step by step directions on what i need to do to have this work , or not spend no more money and sale as is.have'nt even had the car for five days and its been a headache financially and physically.It would be blessing from up above if any one would give me the right thing to do with this problem,thank you and God Bless!
