hi i need to know where to put my engine block heater on my jdm h22a from a 1992 jdm prelude, i know its in the back of the engine near the oil filter, im guessing its the coolant drain plug but just need a confirmation. thanks

is it a big bolt with kinda like a washer built into it ? form what i recall a bit up and to the left of the oil filter location.... i believe that is where it goes in, a 22mm bolt if i recall correct...

it's been quite some time since i've seen the back of one to put mine in.

Yes that's it. You need a 24MM socket.

yeah i just felt the back of the block to the left of the oil filter, it is quite hidden and pretty hard to access if you dont jack the car up at least a foot. i just bought a heater coz its winter already in calgary(canada)....

by the way whats the coolant/antifreeze capacity for the h22a if i just wana drain it out(not flush the system) so i can install the heater..since its hard access i dont want to make a big mess.
