98 Ford Ranger Replacement Radiator
I developed a leak in my radiator on my Ford Ranger. I have purchased parts on multiple occasions from in the past and have always been satisfied. This purchase was no different from past experiences. The price is uncomparable to local parts stores. Shipping was free and I received the radiator two days after placing order. The radiator was a perfect quality replacement. Anytime I need parts I look to without hesitation.

Great Experience!
We ordered a new radiator for our old truck. It was our first order from this company. We were extremely happy with the price (after getting several other prices). The part shipped right to our door, very quickly, with no problems. The tutorial was so helpful that my husband was able to install the part himself, which saved us $100. We are very satisfied customers!!!

Exactly as described: Direct Replacement
As a returning customer I didnt expect any surprises. There were none. Search and order process were effortless. The part was delivered on time and well packaged. The You Tube video detailed each step of the installation clearly and precisely. Draining and refilling the cooling system took longer that removing and replacing the radiator.

Replacement went smoothly and the radiator has started leaking yet.

Radiator installation went smoothly
I watched the 1A AUTO installation video for the radiator installation. It looked pretty easy so I decided to try it myself. After it arrived which was pretty quick, I reviewed the video again. Everything literally went as smooth as the video installation. I did mine in my yard and used a large collection pan to catch the coolant. I am glad 1 A AUTO makes these installation and repair videos. And their prices are GREAT !!!!

Ford Ranger Radiator
The radiator was a perfect fit. The price was about half of any other place I searched. The only negative is that my truck is a manual shift. The radiator works with manual or automatic. It did not come with plugs for the automatic ports. I went to Home Depot and found plugs in the plumbing dept. If not for that it would have gotten 5 stars.

Do I have to use the transmission cooler on this and if not what do I have to do to block those lines?
Steven B November 21, 2017
If your vehicle is an automatic transmission, then you will use your transmission cooler. If your vehicle is a manual transmission you may use rubber plugs to block these additional holes for fittings.
Alex P November 22, 2017
My cooling lines are 16 mms connector size will this fit my truck?
Robert C December 27, 2018
This part is specific to vehicles with a particular set of options. We will need more information about your vehicle to confirm the fit.
