Diagnostics
Diagnostics
A symptom-driven route through a fault. You answer what the car is actually doing, and the page narrows the search, putting the cheap and reversible checks before the expensive ones and saying at each step which test genuinely rules something out. This does not replace the workshop manual for your car.

- An E-Type that runs hotA structured diagnosis. Most E-Types reported as overheating are not overheating, and most that are will tell you which part of the system is at fault before you spend anything.All series, six-cylinder and V12. Nodes that apply only to the Series 3 V12 say so.Open question recorded
- An E-Type that will not startStarting faults divide cleanly at the first question, and most of the wasted effort comes from skipping it. Whether the engine turns over decides which half of the car you are working on.All series, six-cylinder and V12. Nodes that apply only to the Series 3 V12 say so. If the car starts when cold and not when hot, use the hot starting diagnosis instead.Open question recorded
- An E-Type that will not start when hotA car that starts perfectly cold and fights you warm is not a badly maintained car, it is a car telling you which component is failing with heat. The pattern of when it happens identifies which one.All series, six-cylinder and V12. Nodes that apply only to the Series 3 V12 say so.Open question recorded
- Brakes that drag or pullDragging and pulling are different faults with different causes, and on an E-Type the rear brakes are inboard, which changes both what goes wrong and how hard it is to see.All series, six-cylinder and V12. The rear brakes are inboard on every E-Type, mounted beside the differential rather than in the wheels, and several nodes here depend on that.Open question recorded
- A misfire, or an engine that will not idleRunning faults are worth sorting by when they happen before sorting by what causes them, because the same component fails differently at idle, under load, and when hot.All series, six-cylinder and V12. Nodes that apply only to the Series 3 V12 say so.Open question recorded
- A battery that will not chargeCharging faults are easy to diagnose and easy to get wrong, because the E-Type used two entirely different charging systems across its life and many cars have since been converted from one to the other.All series, six-cylinder and V12. Early cars used a dynamo with a separate control box and later cars an alternator, so several nodes ask which is fitted rather than assuming from the series.Open question recorded
