No leaking. May be a bit less liter then my old one but did the great job on running like it originally supposed to be. Not sucking too much from the water as well.

Radiator replacement
April 11, 2020
Replaced the radiator on my 2000 Chevy C3500 with a 5.7 v8. Perfect fit and excellent instruction video made it a lot easier to install with absolutely no issues. Truck is essential to haul hay, feed, and cattle for our small ranch. Have ordered numerous parts from 1a auto and they have been high quality and reasonably priced will continue to use this business
Replace Radiator

I ordered a replacement Radiator for my 94 Blazer. The girl who helped me made sure it was the correct size by asking for my Vin # also. It came in two days. It was of good quality and was a perfect fit..

In my opinion 1 AAuto has the best and rapid service and delivery anyone could ask for.. There products are fairly priced and I have never had to return anything .. I would and will keep referring this Business for any and all your part needs..
August 9, 2020
4 out of 5 since it required adapters (which were included) this added to additional concerns about leaks (none so far) so overall looks like a solid long term investment. This is the first place I check for online parts and the videos are very helpful.
September 19, 2020
Fast easy reliable service and the part fit great! The how to video was spot on. Thanks for helping out!

Customer Q&A
Hey how do i know if my suburban has the engine oil cooler?
August 5, 2017
Juan M
Just look if there is a connection for the oil line on your radiator. The 2 big hoses are of course for the coolant the 2 smaller hard pipe/hose are for oil.
August 5, 2017
Loic N
It should have 4 small lines running to it if it has oil cooler. 2 lines if it's just transmission cooler
August 6, 2017
Joe P
There will be 4 steel lines, plus the inlet and outlet for the coolant, 2 steel lines are for the transmission, and 2 more steel lines for the oil cooler

I have a 1996 Chevy k2500 with the 5.7 L engine that I have removed the oil cooler from. This trick is a manual transmission, so I don't need a transmission cooler either. Do you have a radiator that would fit without the coolers?

July 20, 2021
Rick R

Andra M
Does this radiator have the transmission cooler?
July 24, 2021
John D
The transmission cooler is not included.

My radiator is 34" by 18.1/2" by 1.1/4". The ad shows a shorter radiator that wont work with a 1994 chevy k1500. Do you have a taller one??
September 24, 2021
Juan M
We do not have anything taller, but based on your description this should be the correct one as long as you have the engine oil cooler. This can be confirmed by inspecting your radiator and seeing if both tanks have metal fittings on them. If you have the cooler then there will be a total of 4 fittings.
