Why Is My Car Overheating? — Chico, CA
Car overheating in Chico CA? Pull over immediately. Thermostat, water pump, cooling fan, head gasket. Same-day repair most cases. (530) 826-4275.
The Short Answer: Pull over immediately when the temperature gauge enters the red. Do not drive to the shop overheating — head gasket damage happens in minutes. Call (530) 826-4275 for towing recommendations. Same-day diagnosis and most repairs.
Chico's 105°F summers make overheating a genuine emergency. An engine that overheats for even 5 minutes risks warping the cylinder head — turning a $149.99 thermostat job into a $2,000 head gasket repair. The rule is simple: when the temperature gauge enters the red zone, pull over immediately.
What to Do When Your Car Overheats
Step 1 — Pull Over Safely
Do not push through to the destination. Do not wait to see if it gets better. Find a safe place to stop immediately.
Step 2 — Turn Off AC, Turn On Heater
Switch the AC off immediately — it adds load to the engine. Set the heater to maximum heat and maximum fan. This transfers heat from the coolant to the cabin, buying a few additional minutes.
Step 3 — Shut Off Engine
Once safely stopped, shut off the engine. Do not open the radiator cap — superheated pressurized coolant under the cap causes severe burns. Let the engine cool 30–45 minutes minimum.
Why Is It Overheating?
Thermostat Stuck Closed
Rapid overheating within 5–10 minutes of startup — especially on cold mornings. Thermostat replacement from $365.22.
Water Pump Failure
Impeller slip or bearing failure stops coolant circulation. No external leak in some cases. From $399.99.
Cooling Fan Failure
Electric cooling fan not running at idle — overheats in traffic but stays cool on the highway (ram air cools the radiator at speed). Fan motor or relay. From $199.99.
Low Coolant / Coolant Leak
Check coolant level when cold. Pink, green, or orange coolant puddle under the car confirms a leak. From $149.99 for minor hose leak to head gasket territory if the source is internal.
Head Gasket Failure
Overheating with white exhaust smoke, coolant in oil (milky dipstick), or bubbling in the coolant reservoir. Combustion leak test confirms. From $1,400–$3,000.
