On the XV70 Camry this is a beginner-friendly job with one annoying part: getting the big plastic lower engine undercover off. That is 10 mm bolts plus push-pin clips, and the clips break if you pry them with a screwdriver. Once the cover is down, the radiator drain cock on the lower driver-side tank does the work, and refilling is just slow pouring through a spill-free funnel with the heater on full hot.
The thing most people get wrong is the coolant itself. Toyota's pink Super Long Life Coolant is sold both pre-diluted and as concentrate, and buying concentrate then filling with tap water is a common and expensive mistake. The second mistake is calling it done after one fill — the level drops noticeably as air works out over the first few heat cycles, so recheck the radiator neck cold, twice, before you trust the reservoir alone.

Tool sizes are the same across the 2.5L A25A-FKS, 3.5L 2GR-FKS and the hybrid: 10 mm for the undercover, plastic clip tool, no special drain wrench. Capacity differs — roughly 6.5-7 quarts on the 2.5L and hybrid engine loop, about 8.5-9 quarts on the V6. Hybrids add a separate inverter/power-control-unit coolant circuit with its own reservoir and electric pump; bleeding that loop properly needs Techstream or an equivalent tool to command the pump.
| Radiator drain cock / plug (plastic) | Hand tight only — do not use a wrench |
| Lower engine undercover bolts (10 mm) | About 7 ft-lb (9 Nm) — verify in the service manual |
| Lower radiator hose spring clamp | No torque spec — reseat clamp in original position |
| Engine block drain plug (if fitted/used) | verify in the service manual |
The 10 mm undercover fasteners, plastic clip type, and pink pre-diluted Toyota SLLC are solid for the whole XV70 generation; confirm your car's exact capacity and whether it has an accessible radiator drain cock (some builds are easier drained at the lower hose) against the owner's manual or a factory service manual.
Toyota's schedule for Super Long Life Coolant is first replacement at 100,000 miles or 10 years, then every 50,000 miles or 5 years. Inspect the level and color at every oil change; brown or rusty coolant means change it early regardless of mileage.
A simple radiator drain and refill takes about 6-7 quarts on the 2.5L four-cylinder and hybrid, and roughly 8-9 quarts on the 3.5L V6. Buy two gallons of pre-diluted pink coolant so you have enough for top-offs over the next week.
Don't. The Camry needs a phosphate-based, silicate- and borate-free Asian-formula coolant; Toyota SLLC pink or an equivalent labeled for Toyota/Asian vehicles is correct. Green IAT and Dex-Cool style coolants can attack the aluminum and plastic in this system and mixing them causes gelling.
Yes — the hybrid has a separate inverter/power control unit loop with its own smaller reservoir and an electric water pump, and it uses the same pink SLLC. Draining the radiator does nothing for it, and if you do drain that loop you'll need Techstream or a comparable tool to run the pump and bleed the air out.
