Notice here the “Aisin” (supplier) and Toyota (TEQ) stampings on the casting:

The casting is specifically manufactured by Aisin Takaoka (the emblem is sometimes called “mountain” but that was an aftermarket brand that AT sold in Japan) which is a Toyota Group subsidiary. They manufacture many different types of castings and machines metals for automobile manufacture.

I always use thread chasers in head and block to clean out nasty bolt holes (deterioration of metals through heating and cooling cycles).

The bolt holes for the water pump are a M8x1.25.

Today was also a hardware day.... when I buy new hardware for the truck I always buy in packages of 10 so I have some extra for my JIS hardware supply.

Toyota and their supplier companies make some of the best hardware around. Worth their price.

The water joint needs to be removed from the old water pump and installed on the new one. Use some Teflon tape to seal joint to the pump housing.

Yazaki sensors for the lower thermostat housing. Empty boss is for my mechanical temp gauge in the truck.
