Tank style block heater ?

[rsh4364]

I have been thinking about plumbing my block heater from bottom rad.hose to a threaded cyl.head flange #1402-8949,think it would work better than running thru heater core.Or plumbing up front near thermostat,would keep all heat in block.Does anyone have thread size on the threaded block off plate? I have 2 tank style heaters,one is kim hotstart# tps151gt10-000,the other is kim hotstart3 sb115100-000,which is very heavy duty.Both are 1500W,one has check valve so cant be back fed. And I also have a temro 1000w freeze plug heater which I would use when really cold.None are installed yet.

The temro(aka zerostart) is all you should need unless you live in Antarctica. I have the 600w Temro and my truck has had no issue starting in -15f actual temp(not wind chill).

Wind chill is only for humans, not trucks.

I really want to use the HotStart tps unit as it has a thermostat built in.And I have the threaded plate on the way so Ill see how it goes.
