Ugh.... I Need Some Help Identifying a Coolant Leak

[Burg Boxster]

Pressure test...

A pressure test will provide your answer quickly as to how/why/where your system is leaking causing coolant boil over; as opposed to throwing good $ at various parts in hopes of fixing problem. W/P, cracked coolant tank or bad o-ring on relief valve are likely suspects based on age but pressure test will reveal issue in short order. Until then, lift up carpet in rear trunk and look for coolant there...

Good luck

Damn... I meant to post that... I took the carpet out of the trunk and it was as dry as a bone.

Can I use the Airlift 550000 for the pressure test? I have never used one and haven't even opened the box.

You cannot use the AirLift to pressure test.
It's the opposite. The Airlift creates a vacuum.
You can test for leaks after you empty the coolant by drawing a vacuum and waiting 5 minutes. If the vacuum holds then there are no leaks.
But if you're hunting for a leak, you need to put pressure in the system with coolant to physically see where the leak is happening.
