Volvo help, forum + news for all models

I would suspect camshafts are 180 degs out of sync.

yes, those are the ones.

On my 2004 V70 R a coolant temperature gauge does not work anymore. I have replaced ECT sensor and checked wires in a connector all looks good. After deleting the error code it takes about 5 minutes driving and ECT failure is back. Any advice where I should look? recent posts prove aftermkt sensor ...

For a few years now, I've had the "alarm needs service" message and last year the remote starter stopped working (tried replacing batteries in remotes but no luck).

good job, any problems encountered ?

Usually the white plastic plate cracks, I potted mine with JB weld 3 years ago, problem hasn't returned.

My hat goes off to you RickHaleParker, your idea worked! The water pump is holding. And thank you to everyone else involved. I do have another , very mild, roadblock still. I am very confused about the way these cams are supposed to be. Quick recap: 2006 s60R Timing belt is off, crank mark is at it...

I’m confused. If you have VVT on both cams you don’t have three m6 bolts holding the cams on, unless the 2006 R is completely different than any Volvo I’ve worked on VVT cams are held on to the end of the cam with a huge Torx 45 Pictures needed he's talking about the bolts holding cam sprocket to t...

The car battery was 4.5v ?, very odd.

I'd rather learn to speak swedish than mess with that.

huh, so maybe if it has a short....the short drains the battery,
You can find the fuse that provides v to the temp sensor and pull it, see if the v drain disappears.
Connect your meter between the battery and + wire.
fun and games.

they can fabricate small blanking plate to cover the output to the bevel angle gear which normally connects to the rear wheels prop shaft.

took the pnp out, cleaned it, oiled it, sanded the points, put everything back together, nothing. no go. I then took out the starter wire, the one under the red cable, it was badly corroded, cleaned it, pinched it a little, reinstalled, and the car started like thor's thunder! Jesus Christ, somethi...

its all pointing back to the temp sensor you replaced, did you check voltage at the plug? it should drop as engine warms up. see if you can backprobe the plug.

you'll also need T60 ? bit for the big cam bolt.

Ok, to make this as easy as possible, I just need the correct answer to this hypothetical situation. If you have a 06 s60R, with no timing belt on it, the crankshaft marking is in its correct position to the blocks marking, but the cams are not lined up and am not sure if they have been rotated or ...

My measurements were 30 min after disconnecting the charger. it needs to be measured under load, an automotive meter with built in load resistor...and leave it connected until it stops dropping. I paid less than $40 for my Innova meter, you can see it shows 12v load setting on the dial. https://www...

does the temp gauge in the dash never move ?
pretty sure it takes longer than a minute to start moving.
if it never moves I'd check the fuse first, then the harness.

Might be a stored code from the old sensor.
Maybe try clear codes and test drive. Read again.

surface charge, it will drop before your eyes and settle lower.
winters coming, might be a good idea to get a 12v emergency jump box.

The thermostat usually fails in slightly open position so there should always be fluid inside the hose, with an air bubble at the top. Try filling a little more the coolant tank, above the max line - watch carefully as it warms up so it doesn't overflow. If you need later on to remove coolant, may ...

Rear drain , technically right side of the engine, is on the water pipe It’s a high quality brass fitting on the steel pipe.

its in the block, theres a drain on the back of the block if you need to get it all out.

Watch some pem videos on youtube, or check fuel pressure at the rail.
I think you know pressure isnt good.

you removed the wheel to do the timing belt, I would check the ABS sensor at the wheel is ok, check wire etc, maybe do an ohm test side to side to compare.

its safer to swap the pulley and tensioner out, they're cheap enough. It could be water pump pulley too or the tensioner might be over tightened and distorted. Some guys mention spraying water on pullies to find the squeaky wheel, I'd rather just swap the lot out. any noise or potential problem in t...

Hey folks, So with all the stay home orders, the Volvo hasn't gotten much exercise, and the battery started to run down. So I had been putting a charger on it to bring it up.

doesn't limp mode reset with ignition off ?

I wonder where the sacrificial wear will relocate to after this is welded solid.
It usually moves to the next weak link in the chain.

Big poof sound sounds like the turbo charge pipe is loose or split coupler at the turbo end.

How are the plugs?

I bought 2 marine batteries for my boat at walmart, they lasted a year and were done.

Not much of that goin around these days. Noted.

Serp belt is easy, one person lies on the floor and guides the belt on the lower pulleys, a second person does the tensioner wrench and the 3rd person puts it on the steering pulley. Just like the pro's.

It might help to use vida software to look for codes, not sure if it will show anything though. I'd check the computer cooling fan, theres a 5 amp fuse in the engine bay, listed in the owner manual. Other than that, bad chassis ground that builds resistance? it can be like chasing ghosts until it go...

The small timing pulley cover can stay in place. I recently changed my timing gear behind the harmonic balancer, I didn't touch the cover bolts. If the balancer pulley is secure I'd look more at the serp belt tensioner pulley.
Spraying with water can reveal which one is making noise as its running.

My 2002 v70 XC has gotten really loud at speeds over 40mph. I did drive over a Piece of lumber on the freeway and the left rear wheel seems to be the origin of the noise since then. When I turn more than 15 degrees or coast downhill it will quiet down briefly. The Volvo has 235K miles and rolls on ...

I'd have a machine shop check the head, it might just need a quick shave.

Should I pull the angle gear out completely while changing the turbo and down pipe? It sounds like a painful job with the angle gear around? swapping the turbo is a lot easier with the angle gear out of the way. For me the 2 bolts holding the oil drain pipe flange to the turbo was the hardest part,...

Blacklab467 wrote: ↑Tue Aug 18, 2020 2:54 pm Yeah they're also new too. More of a vibration from a stop feels like driveline related, not so much a noise or rattle.

That does sound like the cheap cv's you installed.
I think I'd try some used OEM's from Erie Volvo.

jonesg, Thank you for the suggestion, but I think we're past that point. With the engine running I can open the reservoir and see and smell exhaust. The engine might be a lost cause. That says head gasket to me, nothing more. Some people scrap the car but its very fixable even for us home gamers.

The plug to the ETM can cause problems, some dealerships just snip it off and pigtail a new connector if the ETM is removed, to prevent comeback complaints.

Do you rely on the torque only?

Does anyone here add a drop of Loctite to make sure it does not come loose?

It would be like putting loctite on lugnuts.

I got a curt from Etrailer, no trimming needed. 04 v70.

Do you have an actual problem that has symptoms like poor running, poor mileage?

I think you just rolled the seal, it helps to lubricate it during install.
Can also leak if the locking ring isn't tight, I tapped mine home with a piece of wood and hammer.

knock them loose with air hammer.

I'm leaking fluid at the rack too, I read the tutorial and... maybe I'll just keep adding fluid for now.
It will have to be done at some point, not today.
I'm thinking of getting a rebuilt rack when I get to it.

It seemed to me the fuse getting no power pointed to something physical rather than software glitch. ...back to modifying my cupholder... Agreed.

You read the voltage at the battery?
should be 14+v , might want to try reading it at the alternator big cable output.
Access is very limited, might be easier from below with car on ramps .

don't forget the rubber cap with a bit of grease over the bleeder.

I would fix the parts car and move on from the XC, or learn to do body panel work.
Maybe both. !

I would suspect low fuel pressure after sitting overnite.
Try keying the ignition off/on a few times to prime the system before cranking the engine.

Its mostly the same problems repeating, with occasional oddball failure.
A few techs post here and software specialists to help keep us from the dealerships.

Voltage across the battery posts should be 14v+ with engine idling.

have you tried tapping the gas in drive , foot on the brake.
To see if the engine is shifting.

To me , the fact it occurs under load says motor mounts are another good place to look.

Although you'd still need to know which are which.

Most coolant goes out the overflow or coolant bottle cap, not through the combustion chamber. Coolant system is 15 psi, engine cyls 140 psi, engine wins the pressure game.

You lost engine oil from the radiator?
More likely to be tranny fluid no?
A severe overheat could be fixed with a head gasket and machine shop shave.
Staying optimistic, noise could be from a toasted water pump.

The pump might be losing its prime. It should be submerged to get proper cooling from the gas.

No. (Typo, sorry) The donor car is a 2007: my car is a 2004. The radiator adds all state that 2001 to 2007 are interchangeable. This is true if you change the oil lines.

Thats gonna need some decent flare wrenches if they're bound up. Regular wrenches will round off the fittings. Crows foot flare wrenches are the cheapest way ., cheap flare wrenches are useless.

Look at the control arm bushings too.

Have you checked fuel pressure at the rail, you can use a cheapo tire pressure guage if it has a schraeder valve, discard the pressure guage afterward.

turn the AC on, fan should come on,
if no, check the power plug on the fan..
if yes , does the top hose get warm, checking for thermostat opening at operating temp. Could be engine temp sensor at thermostat.

I doubt that their is software on the fan assembly. You can look up the part and dig around to see if there is a software download associated with it. Again, look at the fan - if there are only two wires and you can power it on and off with external voltage it is a straight brushed fan. Speed contr...

They're odd like that, you can't work on certain parts of the car without a camera phone unless you're familiar with the puzzle.

Nice jones - I recall from an earlier thread the gear splines are a lot softer than the crank splines so they get damaged and the crank will be fine. That makes sense, sacrificial consumable part.

normally its on the end of the fuel rail .

Try what chrism suggested above.
Get a rag and release the fuel pressure after driving the car.
After a few hours, key on a couple of times to prime the rail and see how it starts.
That will indicate whether a stuck injector is flooding the cyl or not.

I can't recall where I read it but someone wrote the techs at volvo often replace the plug if the etm is disturbed on higher mileages, once its disturbed they have trouble reconnecting it, they cut it off and pigtail in a new plug.
