Question about Opel Combo
1-AT THE BEGINING ,MECHANIC THOUGH IT WAS THE DIESEL PUMP AND INJECTOR,DISMANTLE AND SERVICED BY PROFESIONAL 2-SOLENOID ON THE PUMP IS WORKING PROPERLY ,DIESEL IS SUPPLIED TO THE CYLINDER -THEN ALL THE VALVES AND THE GASKET IN THE PISTON HEAD HAS BEEN REPLACED. STILL IT CANNOT START 3
If the pump has been removed for servicing then I would say that the pump injector timing is off. It has to be set on injection mark and not tdc.. Have a professional injector mechanic check the timing.

As you've stated driving around town it's fine, and everything is working well. For the symptoms, there are 2 possible causes:
1. Your cooling fans are not working.
2. Your radiator needs to be replaced.
I'm sure you can determine which it is, and I wish you luck on your repair.

you need to have the engine coolant switch
checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the
computer will make it a rich or lean mixture to start the engine,if it tells the
computer that it is 75 degrees the computer will lean the mixture like starting
a car in the winter without a choke.

SOURCE: Cracked Cylinder Head
I'd say moderately difficult: here are the instructions for replacing the head on a 2001 Jeep Cherokee Sport with 4.0 L engine:
REMOVAL & INSTALLATION 4.0L Engines
Cylinder head bolts may only be reused one time. If reusing a cylinder head bolt, place a paint mark on the bolt after installation. If a cylinder head bolt has a paint mark, discard it and use a new bolt. NOTE: Refer to Section 1 of this manual for the cylinder head torque sequence illustration. The illustration is located after the Torque Specification Chart.
During the final tightening sequence, bolt No. 11 will be tightened to a lower torque value than the rest of the bolts. Do not overtighten bolt No. 11.
