I helped a friend do a timing belt change today on a 2002 S60. It went okay with a few bumps I'll elaborate on later. My main question is: Now the coolant low-level light is on. When we moved the coolant overflow and power steering tank, I noticed the wiring harness was pulled pretty taught. Do you think we did damage? Can this be easily fixed or do we need to buy a new reservoir with the sensor? Yes the coolant level is correct.

On to lessons learned: When we pulled the crank pulley, we used a steering wheel puller and went a little too long and this pulled the timing belt cog out a little before we recognized what was happening. So when we reattached things we just figured the tightening the crank main nut would seat everything. WRONG!!!!! After we had every thing back together, we started it up without the front cover on to make sue all was well. We noticed the belt kept moving towards the front of the engine on the tensioner. We kept thinking we did something wrong with the tensioner, but that was NOT THE PROBLEM. We ended up pulling the harmonic balance again, and then using a sleeve, hit the timing belt gear, and noted it move back about a quarter inch, (just enough to put it back into proper alignment). After putting it back together all was well (except for the coolant light). Any ideas on the coolant issue?

check the conection on the sensor (unplug and re-plug it in, check for residue)

possible that you pulled on it hard enough to mess up the harness, prolly not the case.

 

The level sensor may have seperated from the resivoir slightly, causing a incaccuarte reading. If its in secure, then repalce the level sensor

Thanks for the advice. I wish I would have looked closer at the bottom of the overflow container. We did look, and it looked like we could see silver on the one wire (solder?), so perhaps we did pull too hard an get a wire loose. I have suggested to my friend to try pushing the wire back. Do you know if the sensor is just pushed into the bottom of the container with some rubber seal or do you buy a new container?

Just get a new sensor. Not to expensive.

 

Agreed you need a new sensor.
