After replacing my rad, thermostat etc, run car up fine, go for a little blast fine, but when i stop my bottom rad pipe is far far harder than my m8's rad pipe,

Thing is i have a uk (ver3) and there's is a sti (ver3), i have samco hoses, m8's standard, do the samco pipes get harder with heat and do the uk differ from import on system pressure ?,

Going to brands saturday 3hr drive and wont to check that it not nothing else doing it.

 

Why's this a problem? The cooling system does create pressure, so it would get harder.

Thanks

Just that we went for a drive from cold, and as soon as we got back checked the bottom rad pipe, her's was soft to the touch and mine was hard thats all.

 

Sorry mate but that's pretty funny.

But about the rad pipes, I think that the aftermarket silicone ones are harder than the standard ones.
When I changed mine over the silicone ones were far more rigid than the standard pipes.

 

Lol, that didn't cross my mind till you mentioned it!

Maybe touch some other peoples hoses and see if theirs are hard or soft haha, jokes.

I wouldn't worry about it, maybe hiscar's got the issue lol.

Thanks
Sam
