high coolant psi =[
I got about 2000miles on my new motor and the other day it started to shoot coolant from the radiator to the res then out the res. I replaced the radiator cap and i ran the car with out the thermostat to see if the new one that was in there was bad but it still dose the same thing. what do i do to fix this????:vash:

You need a new rad cap not a t-stat.

Hopefully it's not the same issue, but certainly sounds like the same thing mine was doing: https://www.miataturbo.net/forum/t39992/
Blown headgasket between around cylinders 2 and 3 was blowing air into my cooling system and forcing all the water out. As soon as I'd crank the car it would just start pissing water into the overflow tank. GL. |

Could be a blockage in the radiator. Mine had one and would regurgitate coolant out the reservoir. Do you have a coolant re-route on the car?

Time for a compression test...
I'm in for the HG. |
+2 on head gasket. If it is blown, it is too late. Retorquing will do you no good. Is there steam coming from the tailpipe?
However, it may have rust in the bottom of the radiator. It happened to me. Is the fluid rusty colored? To fix the problem, I ran the waterpump (electiric on my car) with the drain open, and a water hose forcing into the radiator. The preasure from the hose pushed all of the garbage that was in my radiator core out of the drain hole. Try it with the car off, and then try it with the car running (engine cool) with the thermostat out. Then with the car not running again. Careful about cold water in hot engine. If you pump cold water into a cold engine when it is running, you will not have a problem pumping water into it following engine shut off. It could be a problem if it sat and the block started to heat the water. Continue until the water is clear. This happened to me last week, and it is fresh in my mind. My car ran cool ever since. |
he says its a new motor and new Radiator.
What head bolts did you use? old OEM, new OEM or ARP? what did you torque bolts to? |
You'll be fine if you add some Liquid Head Gasket into your oil.
MT member Mouglie can attest to this. |

Well I'll be damned. That suprises me.
Keep us posted on how long it lasts. I thought that once air and water passes under a head gasket, it would be long gone. |
well time to pull the head and get a new HG, i was in the lot at work warming it up and it started to over heat so i said wtf and now will pull the head tomorrow.

Once they go they are gone. Hot gases will make a small path in the gasket and even tightening it will not close it up. Fel-Pro gaskets are cheap though, any local part store should have one for under $50.
