Hey there, I have a 1993 maza protege and im having some problems with my car overheating, not sure where exactily but there is a bubbling sound as if something is boiling everytime I drive my car somewhere, the sound seems to be comming from the anti-freez overflow tank, the onle thing that prevents it from doing that for a longer period of time is if I turn the heater on :s, not I cant exactily leave it on during the summer soo yeah if someone could get back to me asap I would verry much appreciate it, thanks!

Replace the thermostat a cheap fix and then comeback or read below for your possibilities:

Try replacing the thermostat-not it do the following below:

Have it block and pressure tested-do the block first to pinpoint a combustion leaking into the cooling system or a gas analyzer to sniff for hydrocarbons at the radiator fill neck.

Pressure test: do not do a pressure test if there's leakage at the headgasket this might cause coolant into the cylinders and lock it up or bend a connecting rod if cranked thereafter. The headgasket should be repaired before doing the pressure test.

If the block and pressure test passes check the following: Thermostat, Clogged radiator, Fan clutch, Radiator electrical fan, collaspe hoses, water pump

Hope this help Good LUck
