Buy OEM to be Safe
in 7 months
These coolant fittings are thinner in OD than OEM , To critical to chance a coolant leak . So I bought them from the dealer . This job is very detailed on this year vehicle . Not comfortable using yours being they are thinner and you can feel they are loose in the Fitting hole .
