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).
Where is the water pump inlet on a Miata?
However, based on what I found in troubleshooting my Miata, one should also check to be sure that there is good flow through the bypass line from the thermostat housing to the water pump inlet. First gen. Miatas (1.6L engine) have a 90-degree metal barb for connection of the rubber bypass line at the water pump inlet.
What kind of car is a 1995 Miata?
The troubleshooting I’ve done here is specific to a 1.8L 1995 Miata, you may apply what I’ve done here for your application. This may have been a problem that has been stewing for awhile but became such an issue at Hallett this past summer that I had to solve it.
What does hesitation and bogging mean on a Miata?
If you found this page you more than likely are having issues with “hesitation and bogging” during throttle application in a Miata. This is somewhat of a common problem for this generation of Miata.
How to change air conditioning in a Miata?
1 Can of oil (you can buy the freon with the oil) 2 new nipples. You have to put these nipples on the low and high side. Some have said you don’t have to change the high side nipples. A connecting hose to connect the cans to the car. Gauge to measure how much freon in the system This is what you have to do.
When did the MSS come out on the Miata?
The newest unit first appeared on the ’95 Leather package cars with MSS stereo upgrade. The procedures described here have only been tested on a 1992 “standard” Miata stereo, and not any of the newer MSS systems. They may be the same, or they may not. OVERVIEW OF MIATA RADIO SECURITY FEATURES
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’s the normal air pressure on a Miata?
After hooking the gauges to the high side, we found that the high side pressure was around 350 psi (normal high-side pressure is max 240 psi). You’re probably saying I should have thought of that before, and you’re right.
Where does the belt go on a Miata?
The belt closest to the radiator goes from the engine to the air conditioner compressor then the power steering. Not all miatas have this belt depending on A/C on power steering. The tension in this belt comes from the air conditioner compressor pulley. The tensioner (circled) needs to be adjusted to remove the belt.
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:
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.
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.
What’s the best way to replace a heater core?
You’re replacing the heater core, so you are free to give this a shot, although you may want to reuse one of the pipes – read further below. The other option is to simply cut them off and replace. This works too.
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.
