Getting a little frustrated trying to find the correct 2, 3 or 4 row Aluminum Radiator that is a direct fit for the OEM Copper/Brass model. I have a 1984 K5 Blazer Silverado edition automatic transmission that is a 6.2L Diesel. I don't plan on using electric fans with the radiator. Any suggestions on the correct models available that aren't low end junk. All my Google searches leave me with more questions then I asked. I'm hoping someone on the forum can help. Thanks

 

I have an 86 military Blazer with a 6.5 NA diesel. Go to rock auto.com. They have a copper/brass 4 core radiator for your truck. It is made in the US. They also have an aluminum/plastic tank radiator as well. I just got one this year for mine as well. Pretty affordable too, around $285 if I remember correctly. Good luck.

 

That was easy:

VISTA-PRO Part # 432098A Ready-Rad; Mounting: Top Cradle / Bottom Cradle
w/ Engine Oil Cooler, PLASTIC / ALUMINUM; W/AC; W/H.D. COOLING; W/MAX COOLING; W/O AC

I just followed the above's advice and went to rockauto.com and found the above.
