My car won’t start !

We had a call from one of our customers asking if we could call round to his neighbor who was having car problems. Apparently the female owner had been having problems with her car not starting and she had already spent a lot of money on parts and labor from various other ‘mobile mechanics’ who were still unable to find the problem.

The car was a 2000 Chevrolet Malibu with a V6 motor, the problem was that it would not turn over let alone start. Below is a list of parts they convinced her to buy:

Starter , battery, alternator, radiator (?) and water pump (?) .

The starter and battery could of possibly cured the problem but we are at a loss as to why the alternator, radiator and the water pump would cause the engine to not turn over. After making our own checks we noticed that the spark plugs appeared rusty and there was no coolant in the system, the owner confirmed she watched the last ‘mechanic’ put in new coolant. With our suspicions aroused we filled the radiator and tank with water  and asked the owner to attempt to start the engine. The starter engaged but stopped with a clunk ( symptoms that could be misread as a bad starter or battery), with the ignition off we tried to turn the engine over by hand but it appeared to be seized up. Removing all of the front 3 spark plugs proved my first hunch was correct, I asked the owner to try and start the engine one more time once I was stood to the side of the car.

Sure enough the engine turned over and water came shooting out of the spark plug holes, my initial diagnosis was correct. The engine had overheated so badly that coolant  was seeping into the combustion chambers causing a ‘hydraulic lock’ , this to an inexperienced ‘mechanic’ would sound like a bad starter. We explained that the cylinder heads would need to be removed to check the full extent of the damage, worse case the heads or even the engine block could be cracked and unrepairable requiring a complete motor swap.

Now we could not confirm as to why the water pump and radiator needed replacing but if faulty could of contributed to the engine overheating.

If the most basic checks had been checked first the owner would not of had to spend out $$$$$ for parts she did not need.  Stories like this are  unfortunately  becoming  more and more common , inexperienced and unqualified ‘mobile mechanics’ are preying on unsuspecting motorists when they are vulnerable and it is costing them $$$$ of their hard earned money.

Used Car Inspections can save you money.

If you are thinking of buying a used car in the Orlando area Mobile Auto Diagnostics strongly recommends you have a pre purchase inspection before you hand over any money. Buying a used car can be full of pitfalls especially if you are not sure what to look for, the car may have hidden problems or repairs that have been carried out to sub standard conditions. With todays cars even the smallest of repair could cost thousands to rectify. The addition of multiple onboard computers , electronic transmissions, wasted spark ignition systems, multi point and direct injection systems as well as multi link and active suspension systems means mechanics and technicians of today have to be highly skilled and versatile to work on these vehicles. The down side is that vehicles are put up for sale having had a  poor quality repair or  a temporary fix by an in experienced mechanic because the current owner cannot afford the correct repairs.  The common place for these cars to turn up for sale is in the used car auctions held around the areas of Central Florida. Another place to watch out is the ‘Car Dealers’ that operate from their homes having ‘borrowed’ a Dealers Tag from a friend. They sell as a dealer but most offer no warranties. So what can  you, the consumer and prospective buyer do to protect yourself from buying a potential ‘money pit’ ? The paint work may look nice and shiny and the interior clean and smelling nice but what about the important things like the Motor, Transmission, Brakes and Suspension ? Thats where our services can help you , for a fee Mobile Auto Diagnostics can carry out a full and detailed inspection. Below is an example of what could happen if you buy ‘blind’ without an expert to help you. This owner bought a used car from the Miami area, after driving it around for a short amount of time he noticed a knocking/clunking noise and uneven tire wear. After attempting to have the alignment done he was told the car has worn suspension and an alignment could not be done. After calling us and explaining his problems we promptly turned up to carry out a detailed inspection. What we found shocked and upset the owner as all of the urgent repairs that needed doing would have to come out of his pocket, we explained that if he had had a pre inspection  done before he parted with his hard earned money he would of more than likely made a different decision and not bought this car. The front suspension had worn ball joints, inner bushes and control arms. The passenger side  inner steering tie rod was excessively worn and the rotors badly worn together with the front pads almost on the metal. The worst problem we found is shown in the pictures below, the inner control bushing had completely failed causing the control arm to foul the subframe damaging the mounting area. The damage to the front sub frame is so severe that it is not repairable and will have to be replaced at a great expense to the new owner. With this particular vehicle the subframe is a complete unit that the suspension, steering and the motor all bolt to. The part is only available from the main dealer and the car would have to go on to a chassis jig for the subframe to be changed over. This is a major repair that is very labor intensive. This is an excellent example of why our Safety and Vehicle Inspections will benefit anyone when they are thinking of buying a used car.
