( the metal pipe from the bottom of the thermostat housing goes back to you water pump) this is done to warm the engine up evenly. when the rad pasage opens the othe pasage is blocked off. with out a thermostat you engine is pumping hot water back into it self. i'm not sure what over heating problem you are talking about, cracked heads are very very uncommon here. head gaskets are the problem and it has been fixed in the AU falcon by using a better gasket. Legislation is cathing up but up till now we did what we want. We still have 97 octane with unleaded option.(93 octane). Maybe I can try and find one ECU for u. As far as the head probelm: Ford is checking AU and EF gaskets for me. I took the head in today for repairs. Normally I would discard it but I am taking the chance of welding repair. I will flow the ports a but myself and probably have an exhaust manifold build by a friend of mine. The gasket looks fine, ( will replace) at some stage! it is the head that failed, and probably caused by overheating!

Hi Koos, I am willing to swap your XR6 ECU for my standard ECU, you'll find that your engine will have no more overheating problems. See my note to Tickford 6, a very unfortunate event sometime caused my head to overheat, resulting in the head cracking. The fact that the termostat was removed by some  contributed to the problem.
Thanks for your assistance. Cannot wait to have the Falcon running again, just to leave the BMW's behind.

I have visited this forum quite often in the last 18 months and have noticed that overheating/higher temperatures of the engine were discussed on a number of occassions, and therefor assumed that this is a common problem. That is why I Asked some questions in Aug 04 about controlling the fans. I think you also commented on connecting the fans with a remote switch, which I investigated but due to lack of info on ECU could never do the info. Later in jan 05 I replaced the radiator. But , the learning curve never ends. Thank you for your help. I will keep you informed on my repairs.

Ford have since changed that style of thermostat. The new genuine one that was installed before christmas into my car has no bottom plate. Previously on my EA the LPG installer drilled holes into this plate to assist flow into the heater hoses to prevent the converter freezing.

Three weeks later and the head bolted back on. New head bolts and gaskets and termostat. I started the engine to check for leaks and operating temperature. The temp. was fine, between M and A but the head temp felt very high, on stopping the engine you could hear water boiling. I removed the termostat to ckeck the flow of water but not sure if its OK. I removed the pump, looks fine. Does anyone know the tolerance between the impeller and the volute? At what temp must the second speed on the fans work? Please help! I also have a new radiator fitted.
