Oil Cooler Flushing & Flow Check: Notes
WARNING: This page is about a different car, the 2003 GMC Savana and 2003 Chevrolet Chevy Express. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
Flushing Solution (J-35944-22) is environmentally safe, yet powerful enough to cut through transmission fluid to dislodge any contaminants from the cooler. The safety precautions on the label regarding potential skin and eye irritations associated with prolonged exposure are typical precautions that apply to many similar cleaning solutions. It should be noted that according to General Motors, use of other non-approved fluids for cooler flushing can have an adverse reaction to the seals inside the transmission.
CAUTION:
Do not use solutions that contain alcohol or glycol. Use of solutions that contain alcohol or glycol may damage flushing equipment, oil cooler components and/or transmission components.
NOTE:
Tools required: Transmission Oil Cooler Flusher (J-35944-A), Transmission Oil Cooler Flushing Fluid (J-35944-22), Cooler Flushing Adapter (J-35944-200), measuring cup, funnel, water supply (hot water recommended), water hose with at least 5/8" (16 mm) ID, shop air supply (with water/oil filters, regulator and pressure gage), air chuck (with clip, if available), oil drain container, pail with lid (5 gallon), eye protection and rubber gloves.
