M42 Cooling System Overhaul?

[e dub]

I am looking to overhaul the cooling system on my 318is. i dont know what is all that I should be replacing. I know i want to do the radiator, water pump, thermostat, "mess under the intake" but is there anything else i should replace while im doing the job? Its my first time working on my e30 so I want to make sure I do it right.

Gaskets and belts.

There is no point in replace the radiator or any sensors if there is nothing wrong with them. Save your money.

A radiator shop can test the radiator and tell you if it is leak or is plugged up. Do this before you buy a new one.

The only reason I'm going to replace everything is because the car has 115k and its all original. It sat for a very long time so I want to replace everything as a precaution because its going to become my dd since I no longer have my e36 m3.

I think so, water hoses, vaccum hoses, the plastic water pipe at the engine block, the 2 little fuel hoses connected to the fuel rail, intake gaskets, thermostat, water pump and belts.... I had my fuel injectors serviced with new o-rings while in there also.... replacing my timing chain tensioner as well.
