O dear o dear.
Just bought a Gen 2 turbo diesel. Private sale. Ran good for 200 or so miles with no change in coolants. Then:
1. On an 80 mile trip the truck was overheating on hills then hot all the time with coolant expelled via expansion tank.
2. Radiator cap and thermostat replaced today (bit of a bugger getting at that thermostat!).
3. Flushed rad and block both ways with thermostat out (lots of tiny sparkly coppery looking bits in what was flushing out)
4. Filled cooling system (just raw water for now).
5. Ran engine for only 5 seconds then popped radiator cap. Pressure in the cooling system and lots of frothy bubbles.
I can't see where pressure and bubbles would come from other than combustion gases but please tell me I'm wrong.
Am thinking the head has gone as do a couple of guys on this forum.
Any need for further diagnosis or should i just get on with removing the head?
