Just drive to shj from main dxb - shj road, when u reach shj city center take right turn after that and drive straight.

If you mean engine bay cleaning, feel free to get it by just covering the alternator with plastic bag/cover. However steam cleaning is better than normal wash. If you mean to get engine cleaning inside, then its only advisable if your car is newer than 3 - 5 years, in older cars is not at all advisable, as the carbon deposited inside the engine made a perfect place for engine to move and removal of that carbon or other deposit might make engine more noisy and produce missing or pinking.

Any specific reason to avoid driving 30 mins extra and save 50% cost on labor and parts. Drive to shj BM road and there are many shops selling Mazda original spares at 50% discount, and just behind these shops there are many workshop who can professionally fix those parts too. Labor will be lot cheaper than Dubai, as those workshop have lower overhead cost of rent and staff. Delmon ( 06 5331172) is good garage in Shj opp Alico little bit inside at back.

It depends on what is your requirement and budget.
