Just completed the installation into my 1986 GMC K2500. Fit is perfect. Was not as difficult to install as what I read. I am very happy with this product.

Replaced the leaking heater core in my 1984 Sierra Classic, plowing snow with no heat was no fun so I give this 5 stars! Good heat through core and no leaks!

fit my 1983 suburban perfect

It fits just right no trimming needed.

I got this installed finally, after having it all last winter and not getting around to installing it. It fits my 1989 Chevy Blazer Silverado V-10 with A/C and a 350 gasoline engine. Really enjoying driving to the lake this winter with heat in the truck.

Exactly what was ordered and needed.

Worked just like it is supposed to. Somewhat of a bear of a job, but when you need a heater, you need it bad.
