mastertech29 :

Sounds like you have air in the cooling system. There should be a bleeder screw on top of the thermostat housing, loosen it until a steady stream of coolant comes out. Take the top radiator hose off and fill it with coolant then put it back on. Are your fans coming on when you overheat?

Customer :

The electric fans were inoperative and now are being replaced. New fan clutch, t-stat, expansion cap. This is after a new engine with all new gaskets-intake head and valve cover, pretty new water pump and radiator. Desert is quite hot this past week, 110-120 deg as well. waiting to see if new electric fans work.

mastertech29 :

Ok let me know if it keeps overheating and it isnt putting out white smoke the system will need bled and fill the upper hose like I said before. Keep me posted.

mastertech29 :

If your fans werent working that will most likely fix your problem.

Customer :

No smoke. I was just concerned that the new engine has similar problems to the cracked cylinder head like my old one, everything else would be manageable. The service tech knows to burp the car and bleed the air out, typical Range Rover issue, he is a factory LR guy with his own shop now.

mastertech29 :

if the head was cracked you should see white smoke but he can always do a compression check to be sure if the issue continues

mastertech29 :

if no smoke there would be coolant in the oil

Customer :

Thanks I will wait for the fans......I bought the engine with a replacement warranty but just on the engine not the labor....hopefully it is not that issue.
