Losing coolant Sign In

Hi

I am losing a lot of coolant, blowing white smoke, no external leaks

Is there any way to check if the issue is a EGR cooler fault or cracked head

Vehicle is a Mazda BT50

Sure, cut off the coolant supply to the EGR cooler and see if the smoke stops.

Can't tell you much more than that with the limited info you supplied on a vehicle we don't recognize in the US.

1st, stop using it now it may be too late already with those observations.

Pressure test it's cooling system see where it comes out, even with plugs (if gasoline powered) one or more show wet or when cranked even blow coolant out.

Sounds horrible verify what you can while intact if that active hope to plain see what and where so you can decide fix or find another engine.

At this point anything at all the seals coolant that also keeps it out of cylinders is possible hope for a wild gasket problem if no cracks seen apart you would so you can decide what to do,
