well ill defnetly check out that fuel filter but i got the car from some random guy up in the hills and i think the thermostat might be removed cause its got another fan next to the stock one that always runs its all ghettoly put in there just jumped to a fuse in the panel... i dont think the heater core is plugged cause i took off the lines and they flow coolant. is there i way i can check to see no thermo? or just tear it apart and replace? do you know were this fuel filter could be located?
