Heater Core Repair
Need Heater Core Repair? We diagnose and handle heater core work across New Mexico, Arizona, and Texas. We find the cause before we quote the fix and get your approval before any work begins, with eligible repairs backed by our 5-year/60,000-mile warranty.

How We Find the Cause
No heat, low heat, or sweet-smelling coolant fumes inside the cabin point to a heater core issue. We check coolant level and condition, verify cooling system is reaching operating temperature, test heater core inlet/outlet temperature (both hoses should be hot when heat is requested), and inspect the cabin for coolant residue or fogging. A pressure test isolates external vs internal leaks.
What Not to Assume
No heat does not always mean a bad heater core , more often it's a stuck thermostat, low coolant level, a stuck blend door, or a heater control valve. We test cheaper-first causes before recommending heater core replacement (one of the most labor-intensive repairs on most vehicles).

Frequently Asked Questions
Why is my windshield fogging up from the inside?
Coolant residue from a leaking heater core. Replace the core , temporary fixes (sealants) damage the cooling system.
My heat works on one side but not the other. Heater core?
Usually a blend door actuator, not the heater core. We scan the climate control module.
How much does heater core replacement cost?
Highly platform-dependent: $700-$1,800 depending on dash access. We quote after inspection.
Can a flush fix a clogged heater core?
Sometimes, clogged cores can be reverse-flushed and recovered. We attempt a flush before condemning the core on appropriate platforms.
