There is an o ring in the radiator on the s5 models. there is a detachable neck that uses an o ring. i lost this. where can i buy it from? mazdatrix doesn't have it listed. can i use a t2 intake manifold o ring?

 

Of course Mazdatrix sells it.

 

you can go to any auto parts store and get an o-ring that will work

 

thats the thermostat gasket you dunce. i ordered it and its completely utterly wrong.

 

Oops, sorry.
It's been a while since I had a stock rad and I forgot about the detachable cap neck on the S5.

BTW...how did you manage to order, receive and determine the part's unsuitablity all in the space of two hours?
Mazdatrix's service must have really improved...
