It can be a little expensive to replace the EGR valve on the 1987 Volvo 240 DL. The job takes about 1 to 3 hours and can cost as much as about 240 dollars.
The style of plug is a 9004. I just replaced one in my 91 Volvo 240. The connector was about 5 bucks at the parts store. Make sure you splice the red black and blue wires in correctly!
