Cooling-system diagnosis and refill toolkit

Plan pressure checks, containment, filling and any specific flushing operation.

Plan the equipment

Separate diagnosis from replacing coolant. For pressure checks, choose between a suitable adapter-based tester and a verified universal-fit connection. For refilling, decide whether the vehicle procedure calls for a funnel-based bleeding arrangement or supports a vacuum-assisted refill tool. MV4533 requires shop air; the MV4560 pressure tester uses a hand pump. The updated 24980 funnel kit adds a specific Toyota/Lexus V35A connection but still needs an exact fit check. A backflush tool is only relevant when that separate service operation is appropriate. Add inspection lighting and adequate collection containers, and keep incompatible transmission-fill equipment out of the cooling-system plan.

Check the limits

Follow cool-system temperature and pressure requirements and capture coolant appropriately. Do not treat an 8.8-litre extractor or shallow drip pan as automatic proof of adequate drain capacity. Confirm fluid compatibility and adapter sealing. Vacuum refill and vacuum-hold observations do not establish that every cooling-system fault has been diagnosed.

Oil draining & clean filling

Keep dirty-fluid capture separate from clean dispensing.

17922 multi-drain tub

A broad drain tub for collecting used fluids during suitable oil, transmission, differential or radiator service. Check its footprint and height against the space below the vehicle before ordering.

Check under-vehicle clearance and expected fluid volume/temperature. Used-fluid capture and clean filling require separate containers.

Mityvac MV7201

Fluid Evacuator Plus manual extractor and dispenser

A manual extractor and dispenser for compatible fluids and service procedures. It offers a different collection method from a drain tub where the engine or system permits extraction through an appropriate tube.

Confirm the fluid, temperature limits and access method in the instructions. Do not assume extraction removes all fluid or replaces a required drain-plug or filter-service procedure.

Pneumatic fluid evacuator

The MV7300 is an 8.8-litre pneumatic extractor for compatible fluids, with tubes for access through suitable dipstick openings. It suits repeat servicing where compressed air is available; confirm that extraction is permitted for the vehicle and that the fluid and temperature are within the instructions.

Catch-All drip pan

An eight-US-quart polyethylene catch pan for passive drip containment. Its 24-by-36-inch footprint and 1.5-inch height suit a broad, shallow collection area; it is not a sealed waste-fluid carrier.

Check the available floor area, expected fluid volume, and fluid/temperature compatibility before use.

Cooling-system testing, refill & flushing tools

Pressure diagnosis, vacuum refill and backflushing are separate equipment choices.

Lisle 60900

Heater-core backflush tool

The 60900 connects a garden hose to compatible 1/2-, 5/8- and 3/4-inch heater hoses for controlled backflushing. It is intended for an isolated service operation rather than unrestricted full-system pressure, with coolant capture and the heater-core procedure determining safe use.

Inspection lights, mirrors & pickup tools

Choose for visibility, access or retrieval.
