I know this has probably been covered already, but I'm in need of help! I have just come to change my thermostat as it's knackered. So I followed a guide and got to the point where I remove the hose prior to thermostat. Engine coolant is now all over my garage floor. I expected some but not the lot. Is there any cut off to minimilise coolant loss? If not, where/how do I drain the coolant sufficiently? Is there somewhere near rad?
