VZ V6 Wagon Exc Cooling System Nightmare....

[Simo338]

Hello, I need some assistance, advice, new ideas as to why after replacing thermostat and gasket, radiator and hoses, water pump and gasket, O-ring that seats in the groove on the rigid lower radiator pipe that seats inside the lower section of thermostat housing I still have a coolant leak from rear of motor somewhere in the thermostat housing area but unsure exactly where yet..! I used a flexible arm inspection camera but need to wash all the RED coolant from the area away...! If the thermostat housing gasket hasn't ruptured then I know of only one other possibility being the 2 o-rings that seat in the thermostat housing to take the twin heater coil pipes, now I did not replace them when I did replace the thermostat as they looked and felt fine. But if anybody knows of any other possibilities please let me know.... It's driving me crazy.... Cheers Guys.... Simon.

When the weak spot of the cooling system is removed pressure finds a new weak spot...keep looking.
