so i just had my cambelt and water pump changed (after being 3 years overdue!!!) and all seems well with the car it drives the same however upon investigating under the bonnet i noticed they forgot to reattach the undertray which was knackered and cracked anyway and kept falling down but will it be okay if i just leave it without one? i'm quite concerned about water getting into my 7 month old alternator and ruining it however i do know the petrols do not have one.
leave it as is or replace undertray?
thanks in advance
