Hello car gurus, pls I noticed of recent a consistent vibration & shaking including regular drop of water in the radiator reservoir of my 2003 Toyota highlander the moment I start the car. my electrician however checked the coil & the plugs but said all is well with the electrical system. my mechanic however said the 'indomie' in the exhaust is bad & will have to be worked on. He also said the gasket will have to be replaced & the valves will be checked incase any one is bad for replacement
pls advice me appropriately on the above issues before I give the mechanic go ahead

you need to scan your car first and foremost

There is absolutely no need to open up your car's engine yet.

So many things can lead to car vibration but this one you included coolant level drop in the equation, you would need a level headed technician to carefully troubleshoot the vehicle so that you don't end up having your cart before the horse.

If this car was in my workshop, I would first plug in a scanner to monitor the workings of the plugs coils and then the injector nozzles. In a case where all is fine with the above listed, I would beam my searchlight towards the coolant level drop issue and hope to find an external leak. I just hope the leak isn't internal cos that would mean a blown head gasket, allowing coolant to sip into 1 or 2 of the cylinders.
