Hello,

As long as the engine was not started in general nothing happens if coolant leaks into the engine from the intake side. The best way to get rid of coolant in the combustion chambers is to either remove the injectors or glow plugs, then crank engine over until no more coolant is pushed out.

Cheers, Boris
