Have you found the cause of the problem?

Have you tried the engine temperature sensor? I once had an Alfa Romeo that did the same thing. The temp sensor was reading OK when the engine was running but when i turned it off it was reading minus 40 celsius indicating the problem.

It was faulty even reading the engine temp OK.

I may have found the cause of the whining. My engine number is 127xxxx and i searched online for the timing belt parts and found that there are 2 different tensioner rollers, tensioner and idler pulley for different engine numbers.

I might add that a cam seal was also done because it was leaking a bit of oil.

Hi guys hope i can find a little help from you. I had replaced the timing belt, water pump, tensioner, rollers and serpentine belt. Thing is after this job the car makes a strange whine from the belts area at about 1500 rpm. Before it was silky silent only with the normal engine noise. I shot a vide...
