Ok, so I have seen a lot of threads and products about coolant bypass kits.

One works off of temperature, and the others work off of pressure.

Both focus on the #6 cylinder and the rear head freeze plug.

I have been thinking of two scenarios to try and wondered if anyone has done one of these.

1. Moving the heater core inlet port from between 4 and 5 cylinders to the port between 5 and 6.

I am maintaining the return line between 3 and 4 from a weight loss program.

2. Using a coolant riser delete kit, add a port between 5 & 6 and join it to the return line from the heater core to the water pump.

Also, there are no major engine mods; they would be used to pull 5th-wheel trailers.

Any thoughts?
