2TG Water Pipes

[toyota81]

My 2TG is installed in Starlet rally car. I don't have interior heater now so I blocked the rear water port on aft left side of head and the 1s on termostat housing. Will the water cooling system circulate ok?

Yes it will. If you are having doubts you could always connect the left rear water outlet of the head directly to the thermostat - bypassing the heater core.

This is better to do if, engine is not a stock or almost stock... got more stable head temperature. if i remember correct, there is a small bypass hole between hoses, in that metal pipe what going thru firewall in stock... like 6-8mm by pass...
