radiator pressure

[quote:038774516c="cesarin75"]why is it that after my 97tacoma has been on for awhile i can remove the radiator cap and there is no pressure coming from the radiator.[/quote:038774516c]128000miles

My guess is that there is a leak somewhere and it might be on the verge of cracking. You probably need to take it to a cooling systems expert to get it checked out (probably as soon as possible). Have you changed or repaired the radiator within the last 2 years or so?
