JohnBOY Posted November 28, 2008 Report Share Posted November 28, 2008 Hi,Just picked up a 00 S70 AWD w/90K. Decided to have my mechanic replace the timing belt so I would know it was all set. Ordered the kit from FCP Groton as I did for the 97 850 we had and my nephew just inherited and my mechanic installed. The check engine light came on a few days later just after I refilled the gas tank, which it has done before. So I decided to take it to the Volvo Dealer. They said the timing belt was off a couple teeth and that is what caused the check engine light to come on. I said I just had my mechanic replace it with an OEM kit. They said it was a continental belt, NOT a volvo belt and that the problem needs to be taken care of. My mechanic is not a rookie. He specializes in Saabs, but has always worked on our Volvos over the years. I've had good luck with FCP Groton parts.Any thoughts on whether the timing belt being off would actually trigger the check engine light? Thanks,John Link to comment Share on other sites More sharing options...
MrWinkey Posted November 30, 2008 Report Share Posted November 30, 2008 Conti...makes good stuff,the belt is fine.....Why didn't you take it back to your mechanic to begin with? Yes incorrect cam timing can cause a CEL... If your mechanic cannot read generic obd codes go to autoze and have them read and post back. Link to comment Share on other sites More sharing options...
jschaefer7406 Posted November 30, 2008 Report Share Posted November 30, 2008 Hello,Congratulations on the new car. I have had my S70 AWD since 2005 and absolutely love it. I've already had snow up to the bottoms of the doors and she just keeps plowing through . Anyway, about your belt. 99 and up 5 cylinder models use variable valve timing (called "CVVT" by Volvo, as you may know). Not doubting your mechanic, but if he has never done a belt on one of these models before, it could be showing correct timing at the sprocket but the camshaft is actually out of time. Your engine uses CVVT only on the exhaust camshaft, but the sprocket is spring-loaded. If the proper setting procedure is not followed prior to removing the belt, the sprocket will quickly snap back a few teeth upon belt removal. With that strong return spring in there, it is very difficult to re-time it where it actually belongs. Make sense? If the belt is indeed out-of-time, it will trigger the MIL for sure. If it's not already been remedied, have the DTC's read at Advance or AutoZone and post them up. We'll help you from there...Hope this helps,Joe S. - Volvo Master Technician2000 S70 AWD (121k miles), 1995 850 Turbo (160k miles) Link to comment Share on other sites More sharing options...
JohnBOY Posted November 30, 2008 Author Report Share Posted November 30, 2008 Thanks a zillion for asll the great info!!!!!I took it to the Volvo garage (which is 90 miles away)because the ignition key/lock needs replacing as it has been turning all the way around and most posts said that's a dealer only item. The check engine light has come on several times after I would fill it up and they had a code that said the canister valve in the fuel system was showing to be clogged, but they checked it out and said it was ok. But it did it again, so I just figured it was that problem, not a belt problem. I'll discuss the issue with my mechanic on Monday...may have to have him pick it up and tow it back as I don't dare to drive it the way it is with incorrect timing and it's a 90 mile tripI really appreciate the info for all of you!!!!Thanks a zillion,John Link to comment Share on other sites More sharing options...
jazzyjeff Posted December 1, 2008 Report Share Posted December 1, 2008 Everyone recommended the Continental belt to me when I did my tb change. Been running about 10K now and still fine. I have never heard of a brand new belt stretching enough to jump teeth. Incorrect install could be the culprit but it's most likely that the dealer just wanted to make some "easy" money that day. Good luck in getting it fixed. Link to comment Share on other sites More sharing options...

He plugged in the scanner and read the code and it came up P0014 and I believe he said the message said the timing was "advanced too much". Is this enough info to help direct them as to what to do to remedy the problem.

GregD Posted December 10, 2008 Report Share Posted December 10, 2008 P0014 is caused by the CVVT not operating properly and disables the CVVT. I've had this problem since I got my '01 V70. I did the timing belt immediately upon acquisition of the car in the course of fixing a host of other problems so I don't know if the problem was present previously or not. The CEL was on when purchased due to oil-filled spark plug wells that rotted the insulation booties on the coil packs causing misfiring and it showed several codes but I don't recall the P0014. If I'm interpreting Joe S.'s comment correctly, rechecking the timing marks isn't going to tell me anything. Does the only remedy require the cam locking/crank TDC tool set?TIA Link to comment Share on other sites More sharing options...
JohnBOY Posted December 11, 2008 Author Report Share Posted December 11, 2008 Hi,I'm hoping that Joe will jump back in when he gets a chance to get online and give me some direction on what to tell my mechanic to help remedy the timing belt problem. My wife keeps asking when she can get her car back...I smile and say "Soon Dear"...if mama ain't happy, ain't nobody happy!! Ha ha. I'll keep an eye on the forum.Thanks for the help and support.John Link to comment Share on other sites More sharing options...

Sorry to sound forgetful, but I'm not really sure what it is without accessing VADIS. I can try to find it for you by the weekend, but I don't have the answer right now. I have never had to do it personally because I always followed the recommended removal procedure (therefore not requiring a CVVT reset). Anyway, I'll try to find that for you ASAP. Hang in there...Joe Link to comment Share on other sites More sharing options...
