Coolant Expansion Tank Pressure Cap Pressure Test
W ARNING: Never, under any ci rcums tances, remove the coolant expans ion tank pres s ure cap whi le t he engine i soperati ng. To avoid havi ng s caldi ng hot water or s team bl ow out of the cooli ng s ys t em, use ext reme care when removi ngt he coolant expans ion tank pres s ure cap from a hot cool ing s ys tem. W ai t unti l the engine has cooled, then wrap a t hickcloth around t he coolant expans ion tank pres s ure cap and t urn it s lowl y unt il t he pres s ure begins t o releas e, s t ep backwhil e t he pres sure i s rel eas ed from the s ys tem.
