OEM parts except for the Koyo radiator and A/C condenser.

Thanks! In researching parts for my timing belt service on my v8, I've come across multiple part numbers for the same vehicle and it appears that toyota lists Japan sourced parts as well as USA sourced parts for each vehicle. Given my experiences with my Tundra and its parts (water pump, etc) being made in the USA, I personally would only go with Japan sourced parts like what came on the truck from the factory. Which ones did you go with?

Turned out to be a stuck thermostat which was replaced - wouldn't open up all the way as it was at an angle. Radiator stopped leaking as well. Hope that solves the problem!

Just a quick update, I was wrong about the thermostat. My brother later told me it was the paper gasket that was installed near the thermostat. It caused air to enter the system causing the excessive pressure. So, never use paper gaskets! Everything has been running smoothly with no issues since it was replaced.
