Bridge Classic Cars have the 1968 Jaguar E Type back in the workshop this week to have a look into a few issues the customer has noted with the car.

First up is some electrical issues. The customer reported an issue with the headlights which our technician Paul has looked into and found there was an issue with the fuse box. For this, a replacement is needed to make sure the issue is fully resolved and many happy nighttime miles can be done in this gorgeous dark green icon. We recently fitted an immobiliser to the car on its last visit with us. This has also been a concern to the customer so our team have relocated the system to be easier to access and have less interference from surrounding systems, ensuring the car is safe and reliable.

With winter approaching and the temperature starting to drop, the heater in a classic is even more important. The customer raised a concern about the heater not working so our technicians began to diagnose this for our customer. After all the related cables and pipework had been inspected and found to be in good working order, the heater valve itself was inspected. After thorough inspection by the team here at Bridge Classic Cars, it was found that the E Type requires a replacement Heater Valve.

Next was to inspect a slight leak from the top of the engine. The long-legged straight-six, hidden under that timeless bonnet was gone over by the team and each port and seal was checked. Upon inspection, Paul had noticed that the cam cover at the top of the engine had signs of a leak. With this narrowed down as the source of the issue, a new one is required to ensure the 4.2-litre straight-six remains in good health.
