Hi

Do you think i can temporary replace the igniton coil in Ford Sierra 1991 DOHC with one from a Volvo 850. Need troubleshooting

 

850 only came with 5 cylinders. The middle number of the old Volvo'swould indicate the amount of cylinders. I.e. 740 and 760 were the same cars but with different engines.

 

Should that matter it's only a coil!

You should be able to test with any coil of correct voltage to prove if there is any issues with the old one, but some will give a higher voltage than others

 

It should work, the output can vary, so long as it is only a temporary measure you should be ok I should think?

The only difference with coils is some cars have 'ballest ignition systems', this is where the loom has a resistor built in which reduces the power to 9V which the coil uses opposed to 12V, so you have 'ballest' and 'non ballest' coil's respectively.
