Overheating
#1
I have a 2008 HHR LT 2.4 l, it overheats when accelerating or climbing a hill. I've replaced the radiator, cap, water pump, thermostat, and all hoses, I've also replaced the catalytic converter! No oil in coolant, no coolant in oil! Thought maybe the sending unit was faulty, but if it gets to about 230 degrees, it starts acting like it's vapor locking! It seems to cool down some when at idle! Any suggestions?

Welcome to the site, perhaps a good burp is in order!

Now, I don’t know, so I’ll ask, what coolant did you use? What thermostat? What water pump? Did you replace the balance shaft chain or use the hood tool?
