1998 V70 Thermostat replacement

An above freezing day allowed me to attempt the replacement of the original thermostat which apparently was opening too soon. The back bolt stripped and necessitated my cutting a slot so that a hand-held impact tool with a screwdriver bit could be used. Success! Not only does the engine now heat up rapidly, but runs smoother. Best of all, the heater now throws lots of heat and I dare say the mileage has improved. Prior to replacement, the heat gauge needle stayed just below the half-way point. Now, the needle rests slightly above half-way. A relatively simple fix resulting in big rewards!

Glad you got it fixed! Thermostats can be a real PITA when they fail to work right
