  • Perfect fitment, quality replacement, overflow barb is incorrect size.
I'll be adding coolant to the system tomorrow, however, upon unboxing, the rad seems to be a quality component. Welds seem to be proper (I filled the rad with water prior to install for a leak check, but we'll see what happens after some heat cycles & actual antifreeze is used). Perfect mounting fitment & it's noticably thinner that the alumi-plastic OE rad. Only negative is that the barb for coolant overflow isn't the same size as OE. Rad arrived in good condition; not bent as some other reviews have mentioned. ... show more

  • Leaking.
I have about 3000 miles on this and it is leaking. I asked about warrenty and they said it was over two years old. I get time but it’s still new. I’ll pass

  • Good
So far it works as it supposed to but it took buying a new drain plug. The one that it came with had been threaded in so far that it had split the brass on the threads. Wasted a gallon of coolant on the ground has a result of that. That the reason for the three stars
