TO keep it in place, you could cover it with a rag and zip-tie it tightly to the neck of the coolant tank to hold the cap in place so it cannot fall off.

if you do this, cary extra zip-ties and keep coolant somewhat topped off, checking the level a couple times a day. Relieving all the pressure will keep coolant from entering the engine and destroying everything. Drive it to where you need to and go get it fixed. Don't drive it really hard to help keep coolant temps to a minimum so that you will loose less from it steaming out. - I have seen guys drive like that for weeks before, though it is not the best situation to be in. Just don't let it run out of coolant or your problems will be much bigger.

I designed my own zero pressure coolant system for my own truck. I use regular red coolant and I enjoy not ever having to worry about coolant issues like that.

I will try that again.. Any idea how it passes a pressure test cold, but leaks when hot? Leaning toward the turbo seal? Maybe injector cups.. Hopefully not a head gasket or worse.. Not looking forward to get raped by a stealership...
