Re: Are thick radiators overrated?
One of my worker vans is a 1986 Safari, 4.3 V6, factory 5 speed. Previous owner installed a 4 row all metal radiator eons ago, and 8 years ago, it went toast. Everything else, including fan, pulleys, shroud are dead stock, engine ran at consistent 195 degrees, just right for that setup. A stock radiator is one that is single core, plastic tanks, what most would take one look at and run away. I decided to just get one until I could have a nice 4 core copper radiator built.
In those 8 years, the $110.00 stock EBay single core radiator has been simply great, engine temp is still 195 (EFI emissions engine), winter and summer, no leaks, no problems, no adverse issues, and no problems in the hills, just works like the 4 core did.
