Source: https://route66autorepairshop.com/cooling-heating-ac-services/cooling-system-inspection Updated: 2026-09-17 Business: Route 66 Auto Repair, 1775 W Foothill Blvd, Upland, CA 91786, (909) 608-7699 Hours: Monday to Friday 8 AM–5 PM, Saturday 8 AM–2 PM, Sunday closed **TLDR:** An inspection is **prevention**, not a repair. You get a **written list** of what is failing now and what can be scheduled, with photos where they help. A cooling system inspection is a planned look at the radiator, hoses, fans, cap, water pump area and coolant before a problem leaves you on the shoulder. Route 66 Auto Repair in Upland does it with the engine cold and again at operating temperature, and you get a written list sorted into need-now and need-later. It is the check to book before July heat, a move with a loaded trailer or a drive over the Cajon Pass. ## Who should book a cooling inspection? - Drivers with an older vehicle and no record of the last coolant service - Anyone planning to tow, haul a trailer or climb a long grade in summer - Owners who just bought a used car and want a baseline - Commuters who sit in Foothill Blvd or 10 freeway traffic with the AC on - Fleet vehicles due for their scheduled PM visit ## How is an inspection different from a diagnosis? A diagnosis starts with a complaint, such as a climbing gauge or a puddle, and chases it to a cause. An inspection starts with no complaint. We look at every part of the system for wear that has not caused a symptom yet: a hose that has gone soft at one end, a fan that runs but slowly, a shroud tab that has cracked, coolant that has turned rusty. If you already have overheating or a leak, a targeted [coolant leak repair](https://route66autorepairshop.com/cooling-heating-ac-services/coolant-leak-repair) visit is the faster route. Buying a car? The [pre-purchase vehicle inspection](https://route66autorepairshop.com/diagnostics-and-inspections/pre-purchase-vehicle-inspection) covers cooling along with the rest of the vehicle. ## Our cooling system inspection process 1. **Cold walkaround:** With the engine cold, we open the cap, check coolant level and color, and squeeze every hose we can reach. 2. **Pressure hold:** The system is pressurized with a hand tester and watched for drops or seepage at joints. 3. **Warm run:** The engine is brought to temperature while we watch the thermostat opening, fan engagement and scan-tool temperature data. 4. **Write it up:** Findings go on the repair order with need-now and need-later labels, and photos of anything worn. ## What's included in a cooling system inspection - Coolant level, color and protection reading - Radiator, hoses and clamps checked by hand and by eye - Cap and system pressure test - Fan operation at temperature, electric or belt-driven - Water pump weep hole and drive belt check - Written findings sorted by urgency ## What counts as need-now after an inspection? **Need now:** - Active drip or a pressure drop during the hold test - A fan that does not come on at temperature - A hose that is split, bulging or oil-soaked **Need later:** - Coolant that is due for service but still protecting - Light corrosion on clamps with no seepage - A drive belt with early cracking ## How pricing and timing work The inspection fee is stated at the counter before we start, and it applies to approved related repair. Most inspections fit in a morning when the board allows. If we find something, you get a written estimate before any repair begins, and nothing is added without your call. AAA members get 10% off parts and labor, up to $75, with the card at time of service. ## After the inspection Keep the report in the glovebox. Items marked need-later have a reason and a rough timeframe written next to them, so you can plan instead of guess. Declined work stays on the repair order, which helps the next technician see the history. Call [(909) 608-7699](tel:+19096087699) when you are ready to schedule any of it. ## Frequently asked questions ### How often should I get the cooling system inspected? A good habit is once a year, ideally in spring before the Inland Empire heat, and before any long tow. Older vehicles and those that sit in heavy traffic benefit from a look at every oil service too. ### Will you fix things during the inspection? No. The inspection ends with a written list. Repairs only start after you approve a written estimate, so you decide what gets done and when. ### Does the inspection check the AC too? It checks the fans and the condenser area in front of the radiator, since they share airflow. A full AC test is its own service, and AC work always includes a leak test before any recharge. --- Call (909) 608-7699 or visit https://route66autorepairshop.com/contact for a written estimate.
