Where is the cooling fan located on a Miata?
The base Miata has one fan, mounted on the left (looking forward) side of the radiator, called the Radiator Cooling Fan. The Radiator Cooling Fan motor should use 5.3 – 6.5 Amps.
What should the coolant pressure be on a Miata?
The pressure in the Miata cooling system should be between 11 and 15 psi (25.7 to 29.7 psia) maximum, which would place the boiling point of a 50/50 coolant mixture at around 265¡F (at 15 psi) according to the Prestone labels.
Can a racing radiator be installed in a Miata?
Consider an oversized radiator 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.
Is the water thermosensor on a 1990 Miata?
The 1990 FWM is written as though the Water Thermosensor is the temperature gauge sensor, which it is not. There is no data on the actual gauge sensor, although the manual spec on the gauge itself states that the gauge should point to ÒHÓ for a resistance to chassis ground of 20 ohms (18 ohms for Canadian cars).

How big is the cooling system on a Mazda Miata?
The cooling system capacity is 6.3 U.S. quarts. Mazda s recommended anti-freeze solutions for the Miata are as follows: Remember that the primary task of liquid cooling is to transfer heat energy from the metal parts of the engine to the radiator and then to the air.
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.
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.

Why are the cooling fans not working on my car?
1. Engine running hot 2. Cooling fans do not function 3. Cooling fans stay on at all times Average rating from 129,472 customers who received a Vehicle Engine Cooling Inspection. Most modern vehicles use electric cooling fans to help pull air through the radiator so that it can keep the engine cool.
What causes an engine to overheat in a Mazda?
The engine may overheat due to erratic engine cooling fan operation as a result of a faulty cooling fan control module. Replacement of the fan control module would be necessary to correct this condition. Our technicians tell us the Mazda may provide assistance with the cost of this repair. Ready to sell?

What are the symptoms of a bad cooling fan relay?
1. Engine running hot One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. If you notice that your engine is running at higher temperatures than normal, that may be a sign that the relay is not functioning properly.
Why does my Miata not have a cooling system?
If your fans aren’t working, you’ll overheat. Period. Check under the hood and see if the fan on the driver’s side is running after the engine gets good and hot. If not, you have an electrical problem. It may be as simple as a fuse or an unplugged connector. Or it could be a bad sensor or broken wiring.
Why does the coolant fan run when the engine is shut down?
This behaviour is by design. The coolant fan will run when the coolant exceeds a certain temperature irrespective of if the engine is running or not. Some vehicles even have supplementary electric water pumps set to run after engine shut down to keep coolant circulating.
Where are the fans on a Mazda Miata?
If A/C is installed, there is a second fan on the right side of the radiator called by Mazda the ÒA/C Condenser Fan.Ó The A/C fan motor is smaller and the fan shroud fits on differently spaced mounting points, so the two fans are notinterchangeable.
What to do if your cooling fan won’t stop running?
The fan will discharge the battery quickly if left running. Open the hood and locate the fuse relay box on the driver’s fenderwell. Remove the lid. Look on the inside of the lid and for the mapping of the fuses and relays with their location. Pull the cooling fan relay out of the box. Replace the cooling fan relay with a new one.

What happens to the engine when the fan clutch fails?
As the fan clutch is one of the main cooling system components, it is very important to the proper operation of the engine. When it fails, the engine can be put at risk of serious damage due to overheating.
