So i changed my radiator today because the one i had was having a leak issue so i wanted to replace it.

just finished replacing it and all seems to be well however when i turn the heater on to full blast and highest temp, its still blowing out cold air.

also my temperature gauge went all the way up when i took it out for a drive.

could this just be air in the coooling system and i just need to purge the air system? is it bad if i drive my car like that with the temp gauge fluctuating?

 

Sounds like air in the lines.. I heard getting the air out can be a huge pain in the azz.. I think their is a diy on youtube ..

 

so i took it out for a drive again and same thing happened temp went up but this time i started hearing a hissing sound and when i parked i opened my hook because i noticed some white smoke which i thought was just anti freeze burning off

so when i opened it i found that the over flow tank for the anti freeze was bubbling sound like almost boiling.

went to buy a code reader and all i got was P0507 which apparently is high rpm at idle?

any suggestions?

 

There is air in your system. Search for the numerous threads covering cooling system bleeding. Job can be accomplished more easily with a funnel like .
