Replacing 2004 V70 Power Steering Reservoir with 05? Topic is solved

Post by **Zeeko** » 16 Nov 2018, 11:57

Hey all-

I have a little bit of reservoir leakage on my 04 V70 (it's the reservoir with some sort of little blow off cap on the top). It looks like the 30665496 reservoir on fcp euro doesn't have the little blow off cap anymore, but I also looked at the '05 design and it has both nipples on the bottom of the reservoir and looks like a similar fit. Part number for this one is: 30645621 there any benefit to using this later model design or should I just go with the 30665496 pn?

The 30665496 had an issue with a piece detaching inside. The 30645621 is the latest design and will do but you'll need its rubber hose to the pump as well because the two hoses are pretty different in shape. If you get a new 30665496 there should be no problem with it.

I just want to give a quick update on this. I picked up a nice looking used reservoir (05+ style) for cheap on eBay and decided to forgo buying any new hoses and see if the old ones would fit before slapping 90$ on the table for a 2 ft piece of rubber.

It took a tiny amount of finagling, but the old return hose from the reservoir to the pump works well enough for me and is plenty long enough to reach the barb on the bottom of the reservoir. The other line that goes to the small barb of the reservoir was a bit tricker. I had to pull off the electrical wire that was clipped on in a few places to this hose at the back of the engine and run the hose below whatever hose is going across the bay rather than over it to have enough length to reach the small Barb on the reservoir. The new route seems fine.

I'll give another update after I drive to work tomorrow with it

I'm looking at doing a similar replacement on my '01 V70 and wondered how this newer model reservoir was working for you now, after three months?

Seems great- just make sure you secure the hoses well. It's a little annoying that they're on the bottom and you can't see if there is a leak, but the reservoir itself is not leaking and the fluid is not getting nasty like it was with the original.

Wasn't the defect in the '04 version fixed in newly manufactured reservoirs?

Nevermind, just saw that you said the same thing at the end there.

Interestingly, FCP lists this kit as being compatible with my '01 V70:

However, the reservoir in the kit says it's for an XC90 and that it's not compatible with the '01 V70:

https://www.fcpeuro.com/products/volvo- ... 0-30680304

It appears to be more similar in design to the '05-'07 reservoir, except that the connectors are pointing in different directions. It also looks a bit too chunky to fit into that space so I'm not sure it would really work, but I'm wondering if there are really three possible reservoirs currently being manufactured that would work on these cars?

* 30665496, which is specified for the '00-'04 non-XC90 P2s: https://www.fcpeuro.com/products/volvo- ... 0-30665496
* 30645621, which is specified for the '05-'07 non-XC90 P2s: https://www.fcpeuro.com/products/volvo- ... r-30645621
* 30680304, which is specified for the '03-'04 XC90s and '05-'14 V8 XC90s: https://www.fcpeuro.com/products/volvo- ... 0-30680304

As long as they old hold the same amount of fluid and have the same pressure specs and hose connections, I assume any of them would work, it would just be a question of whether they would fit in the space and how easy it would be to make the connections.
