Where does the coolant flow from on a Miata?
To check, remove the rubber bypass hose from the the thermostat housing to the water pump inlet. It runs almost vertically from the housing to the inlet. Coolant should flow freely from the barb on the water pump inlet once the hose is removed.
Can a racing radiator be installed in a Miata?
If all else fails, especially if you have forced air induction, you should consider an oversized radiator. Aftermarket racing units are available. Another option is to install the radiator from an automatic Miata into your 5-speed. The radiator on the automatics has a bit more cooling capacity.
Where is the temperature gauge on a Miata?
Normal temperature gauge indication puts the needle just slightly to the left of center for the 1.6 and just slightly to the right of center for 1.8 engines.
Where does the cooling needle go on a Miata?
It’s just that between 180°-210°F, it will stick to that 11AM position. If you ever climb over 210°F, you will notice the needle will climb up slowly. At about 210°-220°F, it will sit at the 12 oclock position. At 230°F, you can see the gauge start to move to the 1/2 oclock position.
What should the coolant level be on a Miata?
Make sure your coolant level is correct With the engine cold, fill the overflow reservoir to the “Full” line with your coolant mix. Do not fill it while the engine is hot. This will cause extremely cold mixture to be sucked back into the radiator as the engine cools, possibly causing thermal shock.

What causes a check engine light on a Miata?
This is done by opening and closing an EGR valve. The Miata’s computer calls for the valve to open and close based on a number of factors. If the computer senses that this is not being done properly (valve stuck open or closed or lines plugged), then the CEL is turned on.
