thermostat not opening?

wwilliam54

that fast i would say waterpump

I would think thermostat.

My car goes up to about halfway in about 5 mins., then the thermostat opens and it settles to the normal operating temperature.

Halfway then down? That doesn't sound normal... My temp gauge never reads past about 1/3 of the guage...

Sounds like a classic example of the thermostat not working properly.

Either that or you have no coolant in the rad. (I'll give you more credit then that.)

wwilliam54

rex86

how much does a thermostat usually run for

pillage6

Less than $20, use only Mazda thermostats.

7$ from VB

is this the way it is supposed to be on an fb? i have an 85 gsl, and it goes up to the first dash (past halfway) then back down a little bit (to around halfway). this is the way it has been since i bought it over 3 years. anybody?

my rx7 s1 12a 6 port the temp reaches below 1/4 and wont go higher the only time it went half way was when i snapped my fan belt racing..lucky i lived 5 min away from where we were racing....
i never seen a rotor temp running on half way all the time...

I would get your radiator cored out or get a new radiator if your temp stays at halfway. Costs about $100-$140 depending if you take the radiator out yourself or not, but it will save your engine.

I have had 7 Rx-7's and none of them would get hotter than 1/3 if the radiator was in good condition.

My current fb has a motor swap, listed in my signature, and I have the original radiator and it is still running decent temps, even on long trips or traffic.

poweRX-7

well, i have had the radiator flushed... is there any way that it could be the guage?
