OCPTY 109721-5209-1634081391 Heater Core: Compatible with 1999-2004 Jeep Grand Cherokee
Available Options

If you're driving a 1999-2004 Jeep Grand Cherokee—whether it's a Laredo, Limited, Overland, SE, or Special Edition—and your heater's decided to take a vacation, the OCPTY Heater Core is here to save the day. It's a spot-on match for OEM parts like 90069, 9010384, and a few others (because who remembers all those numbers, right?), so you know it's going to fit like a glove and work like a charm.
Now, let's talk specs, but keep it breezy. This bad boy stands 180mm tall, stretches 160mm wide, and slips in at a svelte 32mm deep. The inlet? A cool 16mm. Basically, it's the Goldilocks of heater cores—just right for your Jeep.
Spotting coolant leaks or catching a whiff of antifreeze inside your ride? That's your cue. Before you dive in, though, double-check your Jeep's details and the part number. Because nothing's worse than playing parts roulette and losing. (Well, maybe a few things, but you get the point.)
