Braunton see the 997 models most commonly for servicing, brake fluid change and suspension geometry setting.
The 997 is a super sports car that is easy to live with daily or as something extra special for the weekend. The design evolution of each 911 model has created a gem in the '97 – drop-dead good looks with the pace and handling to match.
Most of these cars suffer from the same problems as time and mileage increase. Braunton offer a fixed-price menu (parts and labour) to allow owners a simple and swift price for repair, or for comparison.
The most common issues are the water tubes leaking, the tandem pump corroding and the ignition coil pack's insulation breaking down, causing an engine misfire.
997 repairs: The '97 suffers from rusty exhaust nuts and bolts (on the flange joints and on the clamps). Braunton Engineering replace these fasteners with stainless steel items along with new genuine exhaust clamps and clips.
Have you checked your 997 Engine Tandem pump for a rusty cover? Check yours: The pump is situated on the back of the engine on the right hand side (offside), and can be seen by looking up from under the rear bumper. Changing a rusty oil pump is essential - a perforated pump casing will allow pressure and oil to leak. A replacement tandem oil pump requires the removal of the exhaust... If the exhaust fasteners, nuts and bolts have corroded, the time to remove will be extended due to the need to extract the studs with heat.
Have your ignition coil packs been changed in the last 6 years / 40,000 miles? The flat-six engine has 6x ignition coils - these are subject to heat soak from the adjacent exhaust, together with a splattering of road dirt & salt, both of which mean the coil's insulation breaks down in time allowing a misfire to occur.
Each ignition coil is mounted to the head by two bolts - these bolts can become corroded in and at the time of major servicing (and/ or spark plug removal), easily snap and break off. Drilling out the studs and a recoil of the threads solves the issue along with a new set of ignition coils - something that is routinely completed at Braunton.
Has your 997 been checked recently for signs of coolant water leak? The coolant water pipes feature alloy unions with spring clips. These unions become quite corroded and if left to worsen, the union can separate allowing coolant to leak and a potential engine overheat. This leak can also affect the grip of the car when antifreeze is dropped under the car, onto the tyres and the road surface. There are some noteworthy examples on you tube of 997 pipes separating under load and causing major accidents. Ask at service time for a check of your cooling pipes to ensure they are clean and fit for purpose?
Braunton Engineering supply and fit the lower temperature (71 degree) thermostat to reduce running temperature. This allows a cooling system to be controlled by a lower temp thermostat over the standard 83 degree unit. Reduced running temperature has a number of benefits to provide ongoing engine protection.
The key benefits of running your car with a cooler running temperature, are that a slightly cooler engine, will have higher volumetric efficiency - the cooler engine will allow slightly more advanced ignition timing without detonation occurring, which can increase power and fuel economy.
The lower temperature reduces the risk from hot spots within the engine, which in turn adds protection against internal faults (such as scored cylinder bores). Lower coolant temperature will allow the oil to run cooler too, another feature to protect an engine's health.
