WTK: What Radiator cap does a ek3 civic use? 1.1 or 0.9

[P.B.k]

i have a ek3 honda civic with a denso plastic radiator.....i brought a 1.1 radiator cap but was told it suppose to be 0.9....why ? and what will be the consequences if you use the wrong radiator cap......

[3stagevtec]

I believe those supposed to be 1.1

The 0.9 operates at a lower pressure and will reduce the overall effectiveness of the cooling system slightly.. It's safer to go higher than lower, but i'm open for correction..

1.1

0.9 is for cars with bigger radiators; prelude,accord etc

k man thanks

[COROLLA KID]

wat if you have a 3core copper radiator on a eg9 running a B16a? will a 1.1 work or 0.9?

[4carspeedin]

if it is a ek3 it should be 0.9 - the SiRs carry 1.1

[r3iXmann]

if it is a ek3 it should be 0.9 - the SiRs carry 1.1

that's not correct..

[halfdef]
