Warning to everyone with this zd30 engine with egr system
This just happened to me there is a small hose going from the egr exhaust inlet to the block behind the starter motor.
It split leaking all coolent out of the system making the engine over heat to Max temp on gauge
Didn't realise it till I smelt the coolent smell looked at gauge was at Max high temp I pulled over let it cooled looked for the leak filled it up and went home to diagnose. Fixed the hose
Bled the system checked the functionally all working fine no bubbles or loss of coolent thermostat working fine
I'd say rocker cover leaking oil over time swelled the hose to split .
How this helps all ...
