Looks like I'm going to have to replace my heater core in my 2000 Blazer 4x4 LT. Would you all please give me a recommendation for a good heater core replacement from an auto parts store. I want to get a good one that won't fail within a year or two. Any brands to stay away from?

Thanks in advance.

 

most heater cores are good, you just have to completly flush out all the Dex-cool and convert to universal 50-50. Keep up with maintaining coolant and it will last. Yes coolant needs changed

 

i like napas cores. but i did put a core in my,and my dads blazers from advance. So far so good years later
