I have installed many head bolt heaters.
On a V8 sometimes we’d put one on each side.
Then they came out with the ones that looked like a beer can that you could easily put in a heater hose. Some had an impeller inside that would circulate the coolant within the engine.
There were also core plug heaters. Even oil dipstick heaters.
If you live where antifreeze is not needed you can put in water soluble oil or by a anti rust product.
