Answer 1

You have air in the coolant. To bleed it out, do this



1. Start engine with radiator cap OFF, let it warm up. If it is low on coolant, add till it appears full first.

2. Turn heater on FULL HOT so coolant goes through the heater core & back to the engine. Air hides here very easily.

3. You'll see bubbles come out of the engine block. As they come out & break, add more coolant to keep it appearing full. Keep doing this while tapping on the top radiator hose to dislodge the stubborn bubbles and you'll eventually get all of the air out.



Mazda RX-7 owners have this process tried and true as our cars are prone to air in the coolant. For a RX-7, bleeding the coolant takes about 30 minutes on average.

Answer 2

Thermostat installed backwards?



Or



Many times you must bleed the air from the cooling system when you service the cooling system. You may have an air pocket inside the cooling system. Look for an air bleeder valve located someplace high in the cooling system.

Answer 4
