I just wanted to know why does the S5 model RX-7 only has 1 radiator cap unlike the S4 model which had an extra radiator cap on the thermostat housing? I'm just curious and want to know why mazda took out the cap for the thermostat housing.

Thanks

 

no one knows?

 

not sure but did the s5 come with the radiator surge or purge thing, that swirls the fluid down and lets the air bubble out the top like the FD.. if so maybe that is why

 

hahaha i never really thought about that until now....hmmmm im puzzled

 

i have no clue

 

thats what im saying . im so curious as to why they have changed this in the S5 model

 

there is an air bleed plug on the right side of the radiator on the S4 that aids in bleeding the air from the cooling system...

 

so no one else knows why?

 

To add on to this, just wondering, is the thermostat housing interchangeable?

 

if you can take it apart i assume you could switch it out?

oh the mysteries of the rx7, i believe thats why i love these cars haha

 

i have no clue cuz on my car its just the piping that goes straight to the thermostat, theres no thermostat housing there or anything

 

Lol, i ment the s5 and s4, like can I put a s5 onto an s4 thermostat housing place, does the two wholes in the back line up ect.

 

I wouldn't since the s5 one is plastic.

 

No.
