1. SAFETY
WARNING! Ensure all Health & Safety, local authority, and general workshop practice regulations are strictly adhered to when
using this product.
WARNING! Ensure the engine and cooling system has cooled, before opening the radiator cap.
9Maintain tools in good and clean condition for best and safest performance. DO NOT use tester if damaged.
9Wear suitable clothing to avoid snagging. DO NOT wear jewellery and tie back long hair.
9Wear approved eye protection. A full range of personal safety equipment is available from your Sealey stockist.
9Keep yourself, tools, and test equipment away from hot engine parts.
8DO NOT use this tool for any purpose other than that for which it is designed.
8Never lay tools on the vehicle’s battery. This may short the terminals together, causing harm to yourself, the tools, or the battery.
9Account for all tools and parts being used and DO NOT leave any in the engine bay.
9Keep children and other unauthorised persons away from the working area.
9Keep test kit parts clean, store parts in the carry case, and keep this in a safe, dry, childproof location.
8DO NOT run engine while pressure testing.
8DO NOT use in radiators or header tanks with internal neck diameters greater than 45mm.
IMPORTANT: Always refer to the vehicle manufacturer’s service instructions, or a proprietary manual to establish the current
procedure and data. These instructions are provided as a guide only.
2. INTRODUCTION
• Capless cooling system tester uses an inatable bladder to seal the coolant header tank or radiator.
• Bladder system can be used on both screw and bayonet ttings and seals 90% of cars and light commercial vehicles straight out of the box
• Supplied with two adaptors, enabling testing of VAG vehicles with internal threads on header tank.
• Features quick-release couplings, easy-to-read pressure gauge and release valve.

3. OPERATION
3.1. Prior to testing
3.1.1. Make sure you have read warnings before use.
3.1.2. Remove radiator pressure cap and check condition.
3.1.3. Inspect ller neck for any sharp obtrusions that may damage the bladder and remove if necessary.
3.1.4. Check coolant level and top up if required.
3.1.5. To ensure secure tting and positive sealing it is desirable that two thirds of the bladder (g.1.3) is below the lower ange on the
radiator or header tank neck before being inated.
Note: It may not always be possible to adjust the bladder the desirable position (two thirds of the bladder below lower flange). The
flexible nature of the inflatable bladder will create the required seal in these applications.
3.2. Pressure Testing
WARNING: DO NOT run engine while pressure testing.
Note: If testing is being carried out on a warm engine a pressure drop may occur due to engine cool down, which may not be due
to a leak. Pressurise and inspect again after cool down is complete.

3.2.1. Move slide valve so that brass bleed screw is exposed (g.3.1).
3.2.2. Adjust pressure bleed screw clockwise until rm - DO NOT over tighten (g.3.2).
3.2.3. Press the brass bleed screw until the valve slides across (g.3.3).
3.2.4. Operate hand pump to inate bladder to 15 psi (DO NOT exceed this pressure) (g.3.4)
NOTE: Due to the design of the internal pump seal, a vigorous pumping action is required to activate the seal and pressurise
the system. A light or slow pumping action will prove ineffective. The larger the air space within the cooling system being
tested, the more vigorous the initial pumping should be. By filling the cooling system and therefore reducing the airspace
within, less effort will be needed to pressurise it.
3.2.5. Move slide valve so brass bleed screw is exposed (g 3.5)
3.2.6. Operate hand pump to pressurise system to manufacturers specied pressure - DO NOT exceed this pressure as system damage
may occur (g.3.6).
• If system pressure is maintained no serious leaks are present.
• A pressure drop indicates a system leak.
• Continued pressure drop, visually inspect for external leaks.
3.3. Removal from System
WARNING: DO NOT deate bladder until gauge read ‘0’ psi To release pressure from the pump, press the release valve (fig.4).
Ensure the gauge is reading zero to indicate no pressure before disconnecting
3.3.1. Adjust pressure bleed screw anti-clockwise (fig 5.1).
3.3.2. Allow pressure to release via drain hose until gauge reads ‘0’ psi (fig.5.2).
3.3.3. Press on brass bleed screw until valve slides across (fig.5.3).
3.3.4. The bladder is now deflated (fig.5.4).
3.3.5. Release retaining clips and remove (fig.5.5).
4. MAINTENANCE
4.1. This unit is a testing instrument and should be treated accordingly. Keep unit clean by rinsing with water after each use to prevent
internal components sticking.
Note: DO NOT use harsh chemicals or solvents.
4.2. The rubber bladder and safety seal will wear with normal use. Replace bladder or safety seal if any deterioration is noted.
4.3. Bladder Replacement:
4.3.1. Remove centre tube mounting screw from base of centre tube.
4.3.2. Remove centre tube ange.
4.3.3. Remove bladder from stem.
4.3.4. Install new bladder onto stem using a twisting action (use water as a lubricant if required - DO NOT use grease or other lubricants).
4.3.5. Install centre tube ange.
4.3.6. Install centre tube mounting screw with ‘O’- ring and tighten fully. Note: DO NOT over tension.
4.3.7. Inate bladder to three or four times to condition and stretch material.
4.3.8. With bladder inated, immerse in water to test for leaks.

5. TROUBLESHOOTING
5.1. Pressure Drop on Bladder Circuit
5.1.1. Check mounting of bladder to sleeve, centre tube ange and stem.
5.1.2. Check tension of centre tube mounting screw.
5.1.3. Check one-way pressure valve for leakage. Mounted in hand pressure pump. Use genuine replacement parts only.
5.1.4. Check condition of pressure bleed screw and seat.
5.1.5. Check condition of side valve ‘O’-rings.
5.2. Pressure Drop on System Circuit
5.2.1. First conrm the pressure drop is not due to a leak in the cooling system.
5.2.2. Check bladder size is adequate to seal tank neck. Condition bladder by inating to 15psi three or four times o󰀨 vehicle if
required.
5.2.3. Ensure correct adjustment of unit as per instructions (g.2)
5.2.4. Check one-way pressure valve for leakage. Mounted in pressure pump.
5.2.5. Check condition of pressure bleed screw and seat.
