• The GM Thermostat Wrench is designed to work on GM 3.1 & 3.4 liter V6 engines.
• A common job on these motors as is in all motors is thermostat replacement and to do this you must remove the thermostat housing.
• In these applications the bottom housing bolt is almost inaccessible without removing other parts - until now.
• Our GM thermostat wrench with its unique shape and design will allow users to remove and install the housings in a fraction of the time it currently takes.
• The wrench is a 13 mm, 12 point with special bends specifically for GM V6 thermostat housings.
