Heater Core - Nissan vs Aftermarket?
I have an 01 2wd X whose heater core just took a dive off a rocky peir at low tide. Temporarily I've bypassed the heater core (Unfortunately, it's Dec. Fortunately, it's So Cal). I've talked to a couple of mechanics about it and one tells me I should make sure to buy an original Nissan heater core, which runs $329 at the dealership. The other tells me, he doesn't think I need to go genuine parts, but he wouldn't go Kragen, O'Reily, Autozone or whatever, low cost parts house carries which run around $66. He suggested I go with whatever Napa is selling since they have higher quality parts.
Has anyone here had an issue with their heater core and replaced it with aftermarket parts? The one told me the cheaper heater cores don't hold up. When I called Napa, they said they guarantee it for 3 years / 36,000 miles. I did find some genuine Nissan parts house selling the heater core for $244. Is it important enough that I need to spend the extra $200 to $250 dollars on the genuine Nissan part or has anyone used the aftermarket and not found any problems with it?
