Choosing a replacement radiator for a telehandler isn't a one-size-fits-all decision, and in the world of forklifts and telehandlers a new core has to match the machine exactly. You need a unit that matches the machine's model and the physical mounting and hose connections. This radiator is made specifically for JLG G10-55A and G12-55A telehandlers, so the fit question is more straightforward than buying a universal core.
Quick verdict
This is a new aftermarket radiator for JLG G10-55A and G12-55A telehandlers. It is a direct-fit replacement with the core dimensions spelled out, so you can check the fit against your current unit before ordering. If you want a new radiator rather than a repair, this part is worth serious consideration.
Who it suits
This radiator suits an owner or mechanic with a JLG G10-55A or G12-55A telehandler who wants a replacement core with the dimensions already worked out. It's also a fit for a shop that prefers new components over rebuilt cores and wants a radiator with the filler neck and hose sizes specified up front, so there are fewer surprises during installation.
What stands out
1001116780 2990552 91563039S Radiator fits JLG Telehandler G10-55A G12-55A

This new replacement core is made for the G10-55A and G12-55A, and it comes with specific numbers that make the fit easier to judge: 25 1/2-inch height, 27 1/2-inch width, 4-inch thickness, a 1 3/4-inch inlet hose, and a 1 5/8-inch filler neck. That is a solid reason to consider it if you want a direct replacement without adapting another radiator. The limiting side is the price-at USD 2,784.95, it needs to be the right part because the return note says it has to be uninstalled and in the original box.
Meaningful trade-offs
Beyond the price, the other consideration is that this is an aftermarket radiator. If you prefer a genuine JLG-branded component, this isn't that. The specific hose and filler measurements mean you should make sure those connections match your telehandler before making the call.
Bottom line
If you need a new radiator for a JLG G10-55A or G12-55A telehandler, this part takes the guesswork out of the core dimensions and hose connections. It's a new unit with clear specs and a specific fitment, so you can go into the purchase with confidence. Just make sure the price fits your budget and the dimensions work with your machine before buying.
