Fit no problem in a 97 k1500 silverado, only issue is fittings on oil cooler ports were not needed for my setup. These fittings were thread locked in and I basically had to destroy them to get them off the radiator. No need for these to have thread locker on, with o ring seals. Best part is ordered at 7pm on Saturday and had Sunday by noon, thanks to prime.

This product is a nightmare... It stings your eyes so badly, I had to rinse it off immediately. Gave me a terrible allergic reaction and a bacterial infection on top of it!
