I am having problems with the cooling system on my 1990 GT, when I drive anywhere the temp gauge reads higher than normal and the more I drive, the hotter it gets (no shit sherlock) but this is where I am confused. I removed all my hoses coming from the radiator and the water pump and sure enough there was a small hole in both hoses so I replaced them and filled her back up with coolant and then ran it with radiator cap off for a while and then took her for a spin. The engine was cooling just fine and I stayed in normal temp range so I went home, mission accomplished right? WRONG! Next day I drive her to work and the same thing starts happening again! I couldn't believe it so when I got home from work (by this time it was pretty hot) and popped the hood and I can hear the coolant in the radiator bubbling like crazy. Is this a problem with my radiator or with the water pump or what????? Keep in mind I do live in Phoenix, AZ so it is HOT here but that can't be the only problem right??? Thanks for bearing with me, I am new to this but I am learning, at least I know how to replace some hoses now :-)
Thanks Guys
