Hello, welcome. My name is Mike, I will do my very best toassist you with your question.
The gear of the starter itself was seized correct?
Also what type of area was the vehicle sitting for a year?
Yes that is correct, the gear was seized and the car was stored under a car cover in a dry garage.Is there a core plug or somewhere that the water could ingress. The starter motor was covered in a very brown rust and it did not smell of antifreeze.
Thanks for your help, new starter motor fitted and heavily greased. Have only just responded because of computer breakdown.
