i need to find a part number for the cooling pipe that connects the front area behind the grill to the ECU box. I called up the dealer, and they refuse to give out the part number to me. Same story for 5 other dealers I tried, so i figured id try my luck here. Its not expensive from the dealer, but the nearest one to me is quite a ways away. Can anyone help? It's the pipe near the red circle connecting to front area, i'm sure you guys know.

 

It is either 8619305 or 3545307. It should be the 8619305 that number should replace the other one.

 

Thanks a lot, i just ordered that and the antenna mast. Now to discover what the proper plugs it takes. half the people say Platinums are the Devil's candy, and the other half say they have no issues. I installed some NGK BK7RE copper ones I got from Napa for $1.79 a pop. It had a nasty miss before and now it's running like a top. I'm wondering if some Bosch or even the OEM plugs would improve it even further. The dealer said they offer a Bosch Platinum single electrode for the 2001+ cars, once again i think it's the story of them not thinking the C70 uses the older tech. from the S70/V70 series. Here I am ramblin again.

 

I run the Bosch platinums in my 850R running about 12 PSI boost and no problems.
The Platinums are OEM. So either go with the Volvo or the Platinums.
I run them in the white 850 in my sig as well running 12 PSI as well.

 

Platinums are what came out of it, but they look like they might have been the original ones it came with. I died a little inside when i saw them.

 

They could very well have been original. They should be changed every 30K.
I have had very few problems using them.
In 3 years I have had to warranty only 1 for something being wrong with it.

 

Since you're here, you seem to be the resident expert for these things. Every so often if conditions are right, the car makes a whining upon startup/shutdown. It does it regardless of if the A/C is on or off, as that was the first thing i checked (compressor clutch). If the a/c is turned off it will still sometimes do it, although more often with it on and hot outside. What should i be checking? It sounds like a flapper door motor issue that my BMW had at one point.

 

Have someone turn the key on and feel if it is coming from under the intake. If so it is normal. That is the electronic throttle body setting and resting with the key on and off.

 

Interesting, i like the way you think. Just need to pop it off and give it a good thorough cleaning?

 

You can remove it and clean it if you want. It might not make it quieter though. They always make noise.

 

Ahh. It seems to be getting quieter now for some reason, didn't do anything, the temp got a little colder that's all.

 

No matter what the throttle body will always make noise.
