Top radiator hose blew off Range Rover twice!

Question

Top radiator hose blew off on the way to Lake Tahoe 2 weeks ago. Took to shop, replaced coolant and new hose clamp. Replaced head gasket. Thought everything was going good for about 200 miles of driving. Just as pulled into driveway yesterday, top radiator hose blew off again!! Somethings up..... (the hose itself looks ok)

Answer 1

need to put additonal clamp. it is just he pressure.  it is not overheating is it?  

Answer 2

tru you may have an cracked head

Answer 3

probably a cracked head. letting exhaust gasses into the cooling system. this builds pressure in the cooling system and then something has to give. replace hose refill coolant system with water. restart engine if you see bubbles this is most likely the cause. Good luck

Answer 4

change your thermostate because it may not allowing the correct amount of pressure into your engine block it is probably sticking shut
