3.5 Sorento timing belt

roblack · 07-06-2008, 03:46 PM

My 2006 Sorento has 97000 km on it and I asked the dealer about changing the timing belt. They said its 7 HOURS!!! I thought it was more like 3. If this thing isn't changed before 100k I understand it voids the warranty. Or mabey theres no warranty anyway after 100k. What Id like to ask the forum is,has many of you let this repair(maintenance) go and not bothered changing it? What has been the result? Am I not inviting crank-bolt problems by doing this,or don't they apply to the 06's?

This has been a good truck but I question if this really needs to be done.

I would agree, change the belt. You may want to price it at an independent mechanic also.

I let mine go to 87K miles and it apparently had enough slack to skip a tooth and it threw a code for the cam position sensor. I have had some experience with timing belts (BMW and Nissan) and decided to change it myself. It was no easy task, and very difficult to get lined up with the exhaust cam on the passenger side being a particular PITA. I pulled it to the local dealer and had their "Master Tech" R&R the belt to confirm timing was correct because it is an interference engine.

Long story shortened - truck still had cam sensor code and wouldn't run, but the story I got was no compression, must be bent valves and we have to pull the engine to diagnose - $900 to diagnose and repair between $2500 - $6000. He asserted that the cam sensor code was meaningless and wouldn't keep it from running even if it were a bad sensor. I bought a new Sorento for my wife to drive (the 08 is MUCH stronger

) and pulled the 04 home, replaced the sensor myself and fixed the truck for 100 bucks.

Soooo - find a mechanic you trust and have the belt changed. Then drive the trtuck for another 50K miles worry free

I have an 05' with 73K on it. I ussually do the timing belts myself also (Hondas and Toyotas). How do you keep the engine from rotating while you are breaking the crankshaft pully bolt loose? Usually Honda or Toyota require a special tool to hold the negine stationary, while turning the bolt. Did you replace the tensioner or the water pump while you were there?

put bar and socket on crankshaft bolt ....disconnect ignition ...hit the starter ...its loose ....oh yes and make sure the bar and socket carnt hit anyting important !!!

How do you hold it when you want to torque it back?

There is a special tool, but I used long pry bar and a punch. Put the punch in the hole on the balancer and the socket on the bolt. wedge the pry bar between the two and let it hit the frame while you loosen the crank bolt. Reverse the pry bar to tighten the bolt. I would definitely not use air tools on the crank bolt.

The other problem is the exhaust cam on the passenger side of the engine. When the belt is in proper location, that cam is right on top of a lobe apparently. It is a bitch to get it to be still. There is probably a cam locking tool available for that as well.

I used to be able to do some cars just using the accesory belts to hold the crank still. No luck on the Sorento though.

you will find two holes in the crank shaft pulley and you can make up a c spanner with two pegs to hold the pulley ....easier to hit the starter thats how the pros do it ...
As for holding the camshaft pulley ...I would think if you can hold the two together before you release the belt it would make the job easy ....would not two bits of 1 1/2 x3x 1/4 plate with a hole in the middle for a bolt make a clamp to hold the two togeter ?? one front and one rear between the pulleys ..bolt in the middle ??? one set for each bank ....not sure on clearances but have lathe and welder when my time comes !!!

LOL Thou this trick can be done out in the bush. It really should be done by a professional if so. And most here are not that. If anyone does this. PLEASE reply if you can (have the use of your arm still) after how it went. There is so much lack of common sence and full details here I will not go into this further here.
