So I'm pulling my 2014 STi out of storage on Monday and I'll be performing the cylinder #4 cooling mod in a few weeks. I'd like to learn of any tips or trick the community has for performing this. Namely:
- When draining the coolant, is it best to just pull the lower hose on the radiator? Or should I remove coolant from other orifices. I've never drained this coolant system before. So I'd like to remove as much as possible.
- I've seen a few videos of others performing this mod using various kits (VEM, GETADOM, etc.). I've seen some use the lower heater hose and some use the upper heater hose. I was under the impression that the lower hose was correct because that is the return line to the water pump. Is that correct?
- I'm not super familiar with the cooling system in my car. Does the line to the water pump route the coolant the the radiator?
- Just a point of interest question. I'm guessing that there is plug on the driver's side head because of the plug on the head on the passenger side that goes to the turbo AND the heads are just cast from components of the same mold or some other manufacturing practice like that. What do yinz think about that?
