You can by test kits that will indicate if its combustion gas in the coolant.
I don't think they are an over head cam engine. If that is the case, removing the head should be a pretty simple operation and you wouldn't need to worry about any timing issues.
You would need to remove the head to diagnose any of the 3 issues above!
You will have to do your home work though as the bolts may be "torque to yield" so would need to be replaced.

Check out You Tube to see if there is anything on there about head gasket replacement on these engines.

If it was mine, I'd be giving it a go! I reckon an SJ413 would be more of a mission!

Good Luck

Thanks.
It is overhead, rocker arms and everything have to come off.
Forgot to mention the return hose between engine and radiator filled up with air too when tested without pump running.
