overflow
 

im new to this site and i would like to know something very important, its been doing it to me a couple of times, when i go for a ride, after about 30 min, my coolant red light goes on, it says add coolant, then its going into the hot, so i always have to pull over to let it cool down, you hear the prestone bubbling and you hear some air near the rad caps, i was wondering if it could be my radiator caps?? and also the prestone starts leaking everywhere, it stops leaking when it gets cooler... help asap please

You still have air in the cooling system,let it cool and top off the ast and theradiator.

but how can i fix this problem so it stops doing it..change both caps??

1. Have you changed your coolant(Prestone) lately?
2. Where is the coolant leaking from?

well not changes, i just added some last night, and its leaking from the overflow, i checked..

There's alot of info about cooling issues here, perhaps you just need a new cap for the AST.
Does the car start up ok? Are you getting alot of white smoke from the exhaust, does your exhaust smell sweet like coolant? If not, then good.

i hope its only the ast cap then, and my car starts good, no white smoke, nothing.

Then perhaps the AST cap isn't holding enough pressure anymore and is venting coolant to the overflow too much too soon. If you do a search on the forum you'll find alot of info about various issues that might cause your overflow problem.
