Known Issues Fg Xr6T

[Mef6]

Can anyone point me in the right direction for a thread about the crusty ass o-rings that fail on the heater to water pump hose on the 4.0. Mine let go and I've seen a few things mentioned but not much for the fg. Specifically the f6. Assuming it's the same as a normal xr6t but I've seen varying methods with different degrees of difficulty. Any help would be greatly appreciated.

For Ford FG models, the timing cover issue you mentioned is notable, where incorrect bolts cause oil leaks. Ensure a thorough inspection of this and consider using appropriately sized bolts. Additionally, check for transmission shudder, a known problem in some FG models; addressing it under warranty may involve a transmission fluid flush or torque converter replacement. Keep an eye on power steering pump failures, and be vigilant for any signs of suspension wear, particularly with the front suspension bushes. Regular maintenance, such as checking the cooling system and addressing any electronic glitches promptly, will contribute to a reliable and hassle-free ownership experience.

Air conditioning not achieving or maintaining correct temperature .
My Mk1 has had the outside air temp sensor, in passenger side rearview mirror replaced twice. The explanation I received. Its only by knowing the outside temp  that the temp inside is maintained by mixing the cold air from the compressor with believed exterior air temperature. Its not the "fully loaded" climate control optioned version. But still seems to rely on that sensor. Not a really expensive fix, I think today the sensor $26 on Ebay, and if you're good friends with an auto electrician, who knows. it a really quick fix once you have the part. initially it seems like the system is out of refrigerant.

Checking the cooling system.
I had a bad experience with that . What we used to call "welsh plugs" in the side of the block decades ago, now called "freeze plugs".There is one in the rear of the head, a really difficult position where there is a minimum of room between the back of the head and the firewall. So it became a head off, get a professional engine reconditioner to check for head damage  to replace the iceplug. The "the coolant is above normal operating level, going to "limp home mode" and home was just 600 mtrs. Possibly failed, because of a combination of factors. after my servicing dealer went bust it fell to my wifes suburban workshop to provide more "time elapsed" services than km based. And seeing this they might have thought they were being helpful by doing just minor services. Not checking the strength of the coolant. I had an event causing a brain injury so was away from it for months in its early days.
that's my excuse for it. Its been 100% since repair. Just another reason to keep the coolant strength at full strength. its made worse by the location. not easily accessible as it was back in 250cid XB models. And I think all the smarts took a bit longer to realise the coolant was above normal operating range. there was absolutely no steam like would have been the case in the "side of the block"welsh plugs"
