How does Hybrid iForce Max engine cool down the turbos after a hard drive?

[127.0.0.1]

but that doesnt tell you the details

on the 4R, the turbo is water and oil cooled. so if you run it hard or above normal, the reason you do a cool down is to lower the temps of the oil mostly. the water part will still pump since that is tied to a electric pump motor if i remember correctly and will run after ignition off

oil pump will not so that oil will cook that is sitting stagnate at the turbo

luckily for me, my sub division is a single entrance/exit and i have to drive around the loop to get to the house. on top of that either i drive down a long hill .1 or .2 miles and that gives it time to cool down also or i have a slight up hill climb to the sub division entrance. all in all, i get about 1-2 mins of cool down since its only 25-30 mph speed limit.

only hybrids have electric water pump

That’s the ticket!

Thanks.
And thanks for bringing explicit Toyota facts to the discussion.

ah yeah stupid me, should have known. too much power draw on a 12v battery to run them probably.
