Hello! I've been needing to replace my metal coolant tank cap for a while now. I suppose I can't call it a radiator cap, as it doesn't sit on my radiator.

When ordering my hazard light switch, I decided to also get the cap from Fastlane. However, on getting it, I noticed that it had a 124 part number, and is rated at 1.4 bars. Is this correct for a 617 engine, or can damage ensue? I had thought that a 1.2 bar cap was appropiate for this setup...
Thanks!
