Throttle Body Clean DIY – Volvo S40/V50, C30, C70


Throttle Body Cleaning for P1 vehicles- S40/V50, C30’s and some C70’s

MVS Forums Moderator Made In Japan details how to clean the throttle body of P1 vehicles- S40/V50, C30’s and some C70’s.

This is actually from another site, (Thanks to Syrup from S.S.), but I found it so good I decided to copy it here. This should also apply to C30’s and possibly P1 platformed C70’s. First off, if you have opted to remove the air filter box, replacing it with a different intake, then you are miles ahead of those who have to get at the throttle body via taking the air box loose. Anyway, here it goes:

It’s easy in theory but awkward in practice.
I think the throttle body cleaning instructions in VIDA have been written by a Swedish intern – it’s literally a few diagrams and one or two sentences and not enough to get the job done- just enough to scratch you head…

I ended up cleaning the throttle body. As the intake side is was spotless – but on the engine side it was filthy and covered in gunk.

Here’s a few tips to make life easier.

  1. 1/4 drive ratchet with various extensions & sockets
  2. Regular Torx bits
  3. Screwdriver
  4. Small spanner to suit Torx bit

DIY Tool for Fuel Pump

Nice home made tool to remove P2 Volvo’s fuel pump ring! You could make the bottom piece out of hardwood easily, too.

I Cobbled together a quick tool for the plastic ring over the sending unit. Worked like a charm.

Here’s another P2 fuel pump DIY tool, different approach.

How To Get The Blower Motor Out – Volvo V50

Get The Blower Motor Out Of A Volvo V50

MVS member thewhitegorilla asks and answers his question: how to get the blower motor out of a Volvo V50?

It’s a pain in the tail, I’m 3/4 of the way getting it out but can’t release the catch and twist the motor out. Any experienced help will be appreciated. But in answer to your question remove the gas petal and the brake pedal. Various length nut drivers and different length sockets 10 and 13mm, and a lot of plain it’s gonna come out attitude is what gets them out. The toughest part is ignoring the pain that you feel in your back due to the awkward position you must work from. Some others have said to remove the glove box and remove the housing from the passenger side. The writeup I was reading was from a C30, similar, but I’m almost thinking that this extra pita (again very awkward positioning must be attained to achieve removal)is not necessary on the 2007 v50. I will let you know when I’m sure. I have mine removed but still inside the dash. The impression that I’m getting is that the blower motor can be removed from underneath with both petals removed . It looks like it anyway. For now I am trying to get this catch released and get the motor out. Anyone any ideas? here are the pics there is one catch directly above the electric connect and then there is a rectangular recess on the round end of the housing. Anyone know how to release this catch?

Then, success:

I got it out, I had to take the seat out and lay straight in to get one hand on the blower and one releasing the catch here’s a picture to help those after me. Look at the lower left at the middle finger in the picture

And right across from that is a round tab that’ the catch, it’s a little scraped up as I was using a screwdriver then knife to try to hold it in as I turned they both fell out a dozen times easy, finally i took the driver’s seat loose and got to where I could get a finger on the catch and turned the blower and it spun right out.

Pull the Head the Easy Way – Volvo 5-Cylinder

#4 piston got hit by both intake valves. Not a problem, I will polish it smooth before I build it.

MVS Contributor jpgurley shows us how to pull the head of a Volvo 5-cylinder the easy way, with a documented outline of his steps:

I am certain that both Volvo Service Manual and ALLDATA tell you how to do it the hard way. To use their methods, you would want a a lift and lots more time than the way I go at it.

In a nutshell, I do ALL the work from the top and through the passenger side wheel-well. I leave the Turbo and most of it’s attachments in place and pull and replace the head with a cherry-picker and load leveler. There are a few different steps between the P1 engines and the P2, but it is doable on the newer ones as well.

Before some of you guys get skeptical about this procedure, I have done it on over a dozen 850’s, 98 70 series and a few 960’s. In many cases I have done it for less than $150 for everything needed and have had NO COMBACKS on any of them! One engine leaked at the turbo oil drain line, but that may have been there before the job.

One thing that I do (that I suspect few have the equipment to do) is to replace my own valves and cut the seats on ones with burnt or bent valves. But if you have to get a good head or a reasonable machine shop to do the actual head work, that would be an additional expense. So this narrative will be on how to R&R the head.

jpgurley then goes on to document the required tools for pulling the head, and the steps. This isn’t a feverish 100-step list, but rather a complete outline of his method of pulling the head on a Volvo 5-cylinder engine. If you need a very detailed step-by-step head removal tutorial, see this or this classic. Here’s a downloadable PDF of another method. Also: how to remove crud from a removed head.

How to Buy a Volvo V50


Interested in a Volvo V50? Here’s a few comments and tips by owners on how to buy a Volvo V50…

MVS Forums member mathy221984:

A few things I would check are the:

Suspension (drive over speed bumps and listen for cluncks) which could be something as simple as a spring seat or a strut.

Motor mounts (these tend to be an issue with corroding rubber)

Wheel hubs (whip out the trunk jack and lift it a bit and check for play in the wheel hub by pushing and pulling on the tire in a north south direction)

Sunroof drain clog (pull carpet up under one of the seats and push your hand in there and feel for dampness) The clog is an easy fix costing nothing although the damage from the clog (mold, corroded electricals, rust, ect) can cause issues of course especially when it has gone unnoticed.

Be sure to check when timing belt components were last serviced.

If the dealer also is a garage then put the car on a proper lift and check the car from below.

If you find issues which are reasonable then be sure to use them as leverage to negotiate a deal.
