🔧 Camaro - Thermostat Replacement

On your Camaro, the thermostat controls coolant flow so the engine warms up correctly and doesn’t overheat. Replacing it typically involves draining some coolant, removing the thermostat housing, installing a new seal, then refilling and bleeding air out of the cooling system.

Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours

⚠️ Safety & Precautions

• ⚠️ Never open the coolant cap on a hot engine; hot coolant can spray and burn you.
• ⚠️ Support the Camaro with jack stands before going underneath; never rely on a jack.
• ⚠️ Coolant is toxic—keep it off skin, paint, and away from pets.
• Disconnecting the battery is not usually required for this job, but keep tools clear of the electric cooling fan (it can turn on unexpectedly).

📋 Before You Begin

• Park on level ground, set the parking brake, and let the engine cool completely (best: overnight).
• Raise the front and support it on jack stands; place wheel chocks at the rear wheels.
• Set the HVAC to full HOT during bleeding later (this helps move coolant through the heater circuit).
• If you don’t have a vacuum fill tool: use a spill-free funnel and plan extra time to bleed air.

🔨 Step-by-Step Instructions

Follow these steps in order:

Before I lock in the exact thermostat location/fasteners and GM torque specs:

• Are we doing this because of a P0128 code (coolant not warming up) or because it’s overheating/leaking?
• Do you have a vacuum fill tool, or are we doing a standard fill + bleed with a funnel?

Reply with those two answers and I’ll give you the exact bolt-by-bolt steps with the correct GM torque specs and bleed procedure for your Camaro.

✅ After Repair

• Verify the coolant level is stable after a full heat-soak/cool-down cycle (drive, cool completely, recheck).
• Check for leaks at the thermostat housing and hoses with the engine running and fully warm.
• Use a scan tool to confirm engine coolant temperature rises normally and the P0128 (if present) does not return.
