DOES NOT FIT K2500 Suburban 1993

Seems well made but does not fit. Driver side cooling hoses on my truck DO NOT FIT this radiator. This radiator has a much larger opening than my oil coolant hoses on my 1993 K2500 Suburban. I think an adapter would work, but I have no idea of the threads so I am stuck. My truck's been up on ramps for 3 days now and I can't use it. Sent an email asking for help, got no reply.
So Far so good

although it was 1/4 inch thicker it still fit. Had to replace previous radiator due to upper hose connector broke off while removing hose for other issue.

Leaks out of side fitting straight out of the box. 1A auto won't warranty it. I'm taking my business elsewhere and I suggest others looking at this part do also. "100% leak tested" is a lie. I've had good experience with 1A auto up until now, and will no longer be ordering my parts from them.

1st one went into a 2000 Chevy Silverado 3500 7.4L 4x4. Fit perfect. Only the trans cooling line adapters needed to be used with it. The oil cooling lines did not need adapting they screwed in perfect. The 2nd one is gonna go in the 94 Chevy Silverado 2500 7.4L 4x4 soon.

Local ACE hardware should have adapter fittings that will do the job. Everything is a compression line fitting so dont use Teflon tape.
