How does a 94-97 Miata heater core work?
The core has two lines that go through the firewall to connect to the engine. In a 94-97, they are fragile copper pipes. There are two rubber hoses connecting them to the engine. These can be extremely difficult to get off. I had already replaced mine as part of replacing my engine, so the rubber was fairly new.
Why is my Miata heater leaking coolant?
If the leak is bad enough, you can lose enough coolant to overheat your engine. If you see white smoke coming out of your vents, it usually means coolant is leaking out of the heater core and burning off. In my case, it meant I was in for replacing a 94-97 Miata heater core, mine being a 97.
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 hot water go in a Miata?
Hot water goes into the radiator, where air passing through it can cool it down, before it circulates back to the engine again to be re-heated. Since this is otherwise wasted heat, your car also uses hot coolant to heat the inside of the car via the cabin vents.

In my case, it meant I was in for replacing a 94-97 Miata heater core, mine being a 97. In a lot of cars, this job is a massive pain, because getting to the heater core requires disassembling the dash. In the Miata, you can do that if you’d like to, but it isn’t necessary.
What kind of cooling system does a Miata have?
First gen. Miatas (1.6L engine) have a 90-degree metal barb for connection of the rubber bypass line at the water pump inlet. It’s a true 90-degree bend, rather than a radiused one as it probably should be (due to space constraints, I’m sure).
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.
