How do you test a Miata cooling fan?
Is there a way to test the fan? With ignition on, unplug connector on top of thermostat housing. Using a suitable conductor (piece of wire) short (touch together) connector to ground (housing casting). Fan should turn on.
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.
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).

What is the boiling point of water in a Miata?
The boiling point of water at 14.7 psia is 212¡F, and if the pressure is increased, it rises. 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.
Why does my Miata heater freeze in winter?
Thermostat’s, over time, have a tendency to freeze up. They may freeze in the open position, which will result in slower engine warm-up and, in winter, lack of heater output. Or they may freeze in the closed position, causing your engine to overheat. We recommend replacementevery few years – they’re cheap. Note from Magnus Bo Bojesen:
