The faster the engine runs, the faster the water pump spins. The faster the water pump spins, the more water is being circulated through the cooling system. Apparently there is a restriction that is preventing all the coolant from circulating properly at high speeds. You might want to flush the radiator (for sure) or the entire system (if necessary).
Drain the water from your Mazda Protege radiator. Remove the hoses from your radiator. Remove the radiator stabilizing arm. Remove the radiator retaining bolts. Reverse the process to install the new radiator.
I paid $125 online for a radiator for my 1998 Mazda 626 lx.
High pressure tells me of a possible head gasket problem. Have the cooling system pressure tested by a reputable garage; this will answer some questions.
where is the radiator cap on a 2002 tribute
55ltr
the radiator drain plug is located on the bottom of the radiator,on the radiator
in the petrol tank
The problem you seem to be having is the cooling temp sensor. It controls the fan speed which has two speeds. Try that.
