Don't Wait!
Tap Water is Terrible for your radiator. Get it out of there and be sure to use DISTILLED Water only.

Ok...settle down guys. I'll get it changed as soon as I can.
Thanks for the info and helpin a brotha out :)
No more Miata
ok I have the thermostat.
I am installing it this morning, I am asuming its the top radiator hose and it should be somewhere near the top of the engine where the hose goes in like on most cars...sorry for being vague,...I'm still sleepy and don't drink coffee....lol
I am planning on the flush and fill next week.
Any recomendations on a certain procedure that works better than another?
also how many gallons of fluid does a 99 OEM radiator hold?
and would it be ok to just buy all 50/50 mix to refill the radiator?
Sorry I know these questions may seem stupid to some but I have never had to do this on any of the cars I have owned, but then again I drove motorcycles for most of my life and only one was water cooled.
I have replaced thermostats though just didn't flush and fill when I did it.
Thanks again, oh and per TC's suggestion I have decided to hold off on my midpipe til I can decide what type of forced induction I want to get.
I am liking the Header more and more each day its less noisy but has more of a souped up sports car sound without sounding ricey, I think if I can just get some colder air in there that will make a big diffrence.

Do the thermostat and flush-n-fill at the same time (you only need 1 gallon of 50-50 mix). You're going to lose a bunch of coolant when you pull the old stat out and you don't want to replace it with tap water.
There is a drain plug on the bottom of the radiator. Makes life easier. After you refill it, remember to burp the system by running the car with the cap off until you see the water flowing inside the radiator.
You can flush the old coolant down the toilet. Preferred enviromentally friendly method.
Agreed... You can also flush it down a storm drain... DO NOT just let it pool down by the end of the driveway. Antifreeze is poisonous and sweet tasting - local animals will drink it and die a nasty death. At least in a storm drain you can think about poisoning rats.

Lightness? What's that? I drive a PRHT!
Might be a good way to take care of the neighbors cat that is using the wife's flower bed as a litter box!
Some arsenic powdered hot dogs would be faster & more humane.

Radiator cap?
Did you flush the radiator? Did it look crusty inside?
more like moldy...lol what would changing the radiator cap do?

keeps the system pressurized and circulating.
Keeps the radiator from barfing up it's innards as well...
Billy is the car just heating up at speed or is it anytime you have the A/C running?
if its real hot outside or if I have driven the car for a while it will start climbing imediately.
If its cold or cool outside it stays normal, but now even driving over 80MPH gets it moving towards the hot side, where as normally it never moved from halfway on the gauge.
I am thinking more and more that its just the summer heat and the new Header without a heat shield....is this a possibility?
If so would buying a heatshield get it back to where it was before?
I was also thinking about maybe a double core radiator from PWR what are you guys thoughts on that....man thats another $500.
Anyway the wife wont drive it without air and I dont blame her, it don't bother me really but the heating up at speeds over 80 does, so I have to do something.
I am on borrowed time too since the wife HAS to drive the Miata on Wednesdays cause I am gone for work when she gets home and I use the Exterra

What is the condition of the current radiator? Can you tell if it has some build up in it? You can get them cleaned out pretty cheaply if it has blockage.
Also is the radiator & a/c condenser clean or are they packed with bugs and crap?
How bad did the old radiator fluid look when you drained it out?

If your car is Normally aspirated, this is messed up. By the way, use the RX-7 16lb radiator cap. If you are boosted, I'm still looking for the solution so I can't help you there. I'm at the point of cutting the hood and creating an extractor hood.
One last point - I noticed you have an aftermarket header. Did you add any heat shielding to the header or is it just open? That might be contributing to your heat in the engine compartment.
Ahhh, the problems of boost.

It is Normally Aspired.
I don't have a heat shield (yet)
The fluid was kind of hairly looking but still green / yellow
Its not leaking anywhere.
I am thinking the same thing (starting to anyhow)
That its a combination of hot Texas days and the new Header with no heat shield.
I do have a license plate right in front of my radiator also that I am going to take off to see if that helps too, I am so glad I dont have to put it back on!
(I always hated front license plates)
