Why do I keep losing coolant but no leaks?
Hot exhaust eventually cracks the plastic to the point that a small amount of coolant can enter the inside of the intake. Not enough to cause any problems at first, but as it progresses, well, I’ve seen them hydrolock. Sounds like you’ve looked at all the common problems. Maybe it’s time to pull the plenum. ok4450 July 6, 2016, 2:02am #10
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.
Why is my coolant leaking but no dye marks?
It is a slow leaks about an overflow in 2 weeks and no dye marks. The leak may be happening from the bottom hose or radiator drain. It may be happening only when the car is hot when you drive and the coolant is under pressure. Try checking it when it is hot, under pressure and while the engine is running.

What causes coolant to go out of radiator?
The radiator cap can deteriorate over time, letting antifreeze slip through when you are driving. A clogged radiator system could be a problem too as it blocks the flow of the liquid. Check the radiator when the coolant disappears without any trace.
Can a worn out radiator cap cause antifreeze to leak?
A Worn Out Radiator Cap. The radiator cap can deteriorate over time, letting antifreeze slip through when you are driving. A clogged radiator system could be a problem too as it blocks the flow of the liquid. Check the radiator when the coolant disappears without any trace.
