Volvo 240 heater valve upgrade kit replaces 1348252 / 9131998. 

This Volvo 240 heater valve upgrade kit replaces both the early and late style heater valves. It comes with illustrated instructions. The valve in this kit is made so you can fine-tune the amount of heat and it's made to last.

Will have the instructions posted soon, we are just tinkering with this new website software.
