[guest]

Greetings,

on a 1998 v70, I'm trying to find the headlight washer delivery valve or T valve. has anyone replaced one and can advise on its location.

Thanks

Your 70 is probably similar or identical to my 850, therefore this should work for you:

I ended up replacing the T valve that splits the washer liquid stream to the headlight wiper arms' squirt heads. I found this to be the defective part of the system by blowing into the various tubes that connect the headlight washer system. I ended up removing the passenger headlight but this is not necessary. If you do, it's three bolts that hold it in, and getting the bottom outside one out was helped by taking out the top bolt on the hood latch and swiveling this back a few centimeters (you'll see what I mean).

Note: When I found the culprit, I removed it and called Barrier Volvo in Bellevue, Washington and began to describe it. I said,"I need a T valve, it's for the headlite wiper squirters..." and the guy cut me off..., "It's $9.85 and in stock." He knew exactly what I was talking about. This means they see this problem all the time. The trick to this whole repair is to find the valve. I suggest doing this: follow the tube from the drivers headlight by feeling for it in the clip retainers near the horns (last photo). Make sure you have the right line by playing push/pull with the tube where it comes out to meet up with the wiper.

From there, follow it to the left, toward the passenger side, unclipping it if you need to. I found that I could pull the T valve and two other tubes out in front of the radiator to see that I had the right piece. If you do it this way, you won't have to remove the headlight, not that it helps that much anyway. You may have to unfasten the passenger side washer fluid tube from the wiper to give slack for this operation.
