2008 xc70 coolant leak id | SwedeSpeed

Hose 21 locks into hose 39, 2nd pic. One or both of these hoses are possibly leaking. You will need to remove parts in this area to verify the leak better. I would also replace the #1 T-stat assembly and #12 and 26 in the Coolant pump, thermostat pic. #12 hose can split open from the inside and leak. #26 o-ring is not included with hose 12. This hose goes from the block to the oil filter housing. The plastic end going into the block will normally crumble when
removing due to heat and plastic drying out.
