Get yourself a 1.4 bar coolant cap from an e30. Shit will stop exploding.

This one?? --> BMW E30 325i M20 2.5L Engine Cooling Expansion Tank - 17111742232 - Expansion Tank Cap - ES#37938

Yes.

So the idea is to allow the cap to release pressure sooner?? Have you tried this already? No issues with coolant loss??

I like the concept :thumbup:

There is a long thread Slick did earlier this year, I won't derail this thread but that's the concept. Not allowing the system to reach a 2 bar venting pressure means that you won't ever put 2 bars of stress on plastic cooling components (30 psi)

SlickGT1, Ricky Bobby, thanks:thumbup:

The answer is always E30 :thumbup:

Quoted for truth. God's chariot comes through with a solution again. lol

Sorry couldn't resist. I have 3 e30's currently and love every one of em. 92 vert, turbocharged 91 318is, and 87 325e.:thumbup:

Went all summer with it. Not one drop lost.

Drove E30 ///M3s at the Skip Barber Driving School 25 yrs ago.

Awesome drivers car. :thumbup:
