About a few months ago I got a new radiator put in, everything seemed to be ok had it topped off and burped. now I finally got the car from a friends house to my house yesterday and everything was still fine. But today I went to drive around see if theres any issues and went great till i was on my way back home. All i saw was white smoke in the back and under the hood pulled over and cut the car off and all over the road and u can smell was coolant. the temp gauge went right to the red line when this happen. before it did it it was right in the middle at 220. which is where it was at yesterday also. I clean everything from under the hood cause it sprayed everywhere and tried to see where this leak was but havent found anything. no leakes from the piping I pulled them off and ran it under a sink, and the radiator doesnt leak as well. any ideas what can cause this to happen?

 

The thermostat might have stuck closed and blew coolant out of a worn out radiator cap. Just throwing it out there.

 

well that could be cause the cap is old i didnt get a new one when i got the new radiator. so ill get a new one and how can i see if the thermostat was stuck closed?

 

Try a new radiator cap with the right poundage for your car and we can go from there.

 

ok and does the old cap say what the poundage is

 

and also since it is a different radiator would the poundage change for it?

 

It should say on the top of the cap what the poundage is but just in case someone put the wrong cap on I would have them check at the parts store what poundage it should be.

 

ok will do thanks for the help

 

OK so I just got some more coolant and filled it up and now found what the problem was. does anyone know what that peice is called in the picture?

 

I am pretty sure that is your heater control.
