So decided to go silicone hoses and flush the cooling system in the e30. Started noticing a little bit of corrosion and thought this would the best thing while changing the hoses and thermostat. If you're gonna do this you might as well flush the system at the same time, I used the prestone super radiator flush to flush it out, and then put the hoses on. Makes the bay look better and wont have to change them most likely for the life of the car.
