Hot water from coolant Perkins

Hi folks, I have a 1973 Perkins 4-236 on a Cal 2-46 with the header tank mounted on the front/top of the engine. I am trying to figure out where to tie in a coolant loop to heat domestic hot water through my hot water tank which has a heat exchanger. Can anyone help with this?
I have read some good posts on this and I think I am going to have to remove the header tank to access some fittings.

Thank you
Brian

Here you go. Blue hoses.
One connection is on top of coolant pump
Other is teed off temp sensor on head.
All photos need to turn 90 degrees clockwise.
Hope this helps

Re: Hot water from coolant Perkins

You are welcome. It was a reminder for me to replace the connector on my thermostat wire.
