I don't know what they sell in Guam, but be sure you get the 88c OE or a 180f if it's a thermostat from the US.
All the books list a 195 in the US which is too hot. US thermostat temps are when they start to open, not when they are fully open, like the 88 OE is.
Four wheel drive allows you to get stuck
in places even more inaccessible.
