Description
Vacuum Coolant Filler Kit with Gauge and Adapters, Radiator Bleeder for Cooling Systems
-
No more repeated bleeding: pulling a vacuum on the cooling system before refilling helps eliminate trapped air pockets in one pass
-
Know exactly where you stand: a color-coded gauge shows the vacuum level and whether the system can hold vacuum before refilling
-
Fits more than one vehicle: a 3-step tapered adapter fits a range of radiator necks, plus a dedicated red adapter for compatible Mercedes-Benz systems
-
Watch the coolant as it flows: the clear 47.2 in hose lets you see coolant move instead of guessing
-
Reach tight engine bays: a 15.7 in extension hose adds reach in confined compartments
Refilling a cooling system the old way usually means topping it off, running the engine, finding an air pocket, and starting over. This vacuum refill kit pulls the trapped air out first, then uses that same vacuum to draw fresh coolant in, cutting down on spills, repeated bleeding and the time a coolant service takes. Two independent control valves keep air evacuation and coolant intake separate, so there is less room for a filling error.
As a cooling system bleeder it works with a compatible air compressor: connect it, evacuate the air, then let the vacuum draw the coolant in. Brass quick-connect fittings resist rust and corrosion, and every piece — the vacuum unit, both adapters, both hoses and the fittings — packs into a molded carry case with dedicated compartments for home-garage or professional workshop use.

Key Features
-
Vacuum Fill Process: connect a compatible air compressor to remove trapped air from the cooling system, then use the vacuum to draw in fresh coolant, cutting spills, repeated bleeding and service time.
-
Color-Coded Gauge: shows the vacuum level in real time and checks whether the cooling system holds vacuum, while two independent control valves separate air evacuation from coolant intake.
-
Two Adapters Included: a flexible 3-step tapered rubber adapter fits a range of radiator necks and expansion tanks, plus a red adapter for compatible Mercedes-Benz systems, with a soft rubber cone that protects contact surfaces.
-
Brass Quick-Connect Hoses: rust- and corrosion-resistant brass fittings connect a 47.2 in (120 cm) clear PVC hose for watching coolant flow, plus a 15.7 in (40 cm) flexible extension hose for confined compartments.
-
Complete Organized Kit: the vacuum unit, both adapters, both hoses and the fittings pack into a molded storage case with dedicated compartments for garage or workshop use.
