2.4jtdm broken belt
Hello fellow alfaholics
I've had the misfortune of a broken alternator belt on my 2.4 jtdm 159 this week and wanted to share my experience whilst collating any info from others who might have had this happen.
The car had 194k kms when I bought it 6 months ago and was overdue a belt change. I bought it and changed the cam belt, waterpump, serpentine belt and all other major service items myself. I left the alternator belt as it looked fine and is difficult to change having no tensioner and being a stretch belt.
More the fool I am now.
Anyway, I haven't seen any other threads where someone experienced this. The car won't start and the implication is that the cam belt has either broken or jumped a couple of teeth. When the alt belt failed I was pulling away from traffic lights and the car came to an abrupt halt.
I have had it taken to cilberti in Osbourne park, wa. Their mechanics take the whole front end off the 159 to change the stretch belt, which is interesting and labour consuming as the radiators are removed all to access the alternator.
I am letting them run with their method for now but will probably take the car back if they suggest the valves are bent and cam belt gone as I have read that the system is designed to fail at the lifters rather than bend valves.... If indeed the cam belt has been affected.
Can anyone explain why the 2.4jtdm might not start in the event of only an alternator belt failure?
I'm simultaneously running a thread on Aus Alfa for this.
