My 2008 EX35 AWD (80k miles ) radiator was also replaced right before my extended warranty ended.
I told service dept to check for any issue that covers by the warranty.
- I complained about a tiny oil weep by the engine camshaft manifold gasket area (driver side)
I do hate Infiniti engine for this common issue. My 2015 Q40 at 7k miles has that issue as well same area.
- I told them I saw some green colored solid wax coming from the inner side of the radiator.
Found out I have a cracked radiator.
The weird part was, when I brought my car to another dealership a year ago to fix the oil leak behind the timing chain cover ($3000 bill under warranty) they also ordered some cheapo
Radiator leak sealer. ( I had to google and investigate the actual parts they ordered)
Found out this dealer is scam. ( Infiniti Waukesha , WI) They did a crappy job reinstalling back my front bumper, broke some studs in my front grill. ( I believe I documented this issue here in the forum with pics) After that I went to another Infiniti service dept. ( Infiniti Glendale, WI) and they did finally replace the radiator.
Both issues were fixed under warranty.
BTW, here is my Infiniti Waukesha , WI experience. Please stay away from their service dept.
