Overview
A fully brazed aluminum core is built to fit the exact shape of the Jeep Wrangler's original equipment heater casing. Each core is leak tested, and it is described as a drop in fit.
A part matched to the original casing and the OEM number is the safest way to replace a heater core. The weak point is that the listing gives no model years, only the OEM number in the specs to match against.
Who it's for
A Wrangler owner or shop doing a heater core swap can use the OEM number to cross check fit. Anyone who needs a confirmed model year list, or whose vehicle is not a Wrangler, should look elsewhere.
Pros and cons
- Fully brazed aluminum design
- Every core leak tested
- Drop in fit in the OEM casing
- OEM number listed for cross checking
- Wrangler model years not listed
- No warranty term listed
- No hoses or seals mentioned
Performance notes
A heater core is a small radiator: hot engine coolant runs through brazed tubes and cabin air picks up the heat. A leak test checks the seams, and matching the original casing preserves the airflow path through the core as designed.
