I have jus gotten an '03 MR2 Spyder, and am new to the MR2.
I have read about air problems in the cooling system and found I had air in mine..
I have seen reference to an engine side bleeder valve, but I can only find the 2 valves in the front of the car..
am I missing 1 more?
Is the only way to add fluid is the resivor ?

Is it possible to have air get into the system ? ( like a leak in the system ) or was it just not bled properly by the used car dealer ?
