Just got a new radiator for my ranger, and it is almost the same design, except for a few minor flaws. On the side of the new one, there's two connectors (I assume that's what they're for), but my old one doesn't have them. Any ideas if I could plug the extra connectors, or would I have to get a different radiator?

 

Welcome to the forum

The two ports/holes are for an automatic transmission hook up, trans cooler, no coolant will leak out of those holes, it is just a closed tube inside for transmission fluid to circulate thru.

After a certain age, about 15 years old, radiator manufacturers only make replacement radiators WITH trans coolers because they can be used on manual or automatic vehicles.

Radiator size and coolant capacity is exactly the same with or without trans cooler, so the new radiator will work just fine
