An induction in heat

Aftermarket's independent test bench tries out the BISON heat inductor from Boston

Tool: BISON heat inductor from Boston

Tester: John Tinham

Price: £1,290 + VAT

Heat inductors are useful tools in these and a number of other situations. Heating a bolt, or the surrounding area, softens the metal and makes extraction easier. In addition, they can be used for badge and trim removal, smoothing dents and removing windscreens and windows.

The one thing you will notice with the BISON is the large yellow box which houses all the electronics and fans to ensure the system remains cool even when used for longer periods. The heating probe itself is a separate piece, meaning it can be used in tighter spaces. Included in the kit are a number of different elements, a 20mm vertical and two horizontal heating coils (20mm and 36mm) as well as a flexible rope coil. These are packed into a protective case, keeping them stored together until they are needed.

Some other heat inductors are a bit heavy and cumbersome in the hand, as they have all the electronics and cooling together in the handset itself. This is where the BISON is better with its separate box for the electronics. The cable (2.5 metres) is long enough so you don't have to pick the box up as well, while it is easy to get into the tightest of spaces. Boston also says that with the lack of electronics in the handset, it is safer, for example, if you find an unexpected water leak.

I was able to use the kit on a bike that I am currently restoring. Older bikes have stickers which are irreplaceable but should be kept if possible, however I need to restore the bodywork, meaning they had to be removed. Using the inductor pad (sold separately), I was quickly and easily able to remove four of the stickers, which can be reused. I was quite impressed with this, as stickers are often very difficult to get away from bodywork. The pad would be good with trim and badge removal as well as any other area which would require a flat heat.

At £1,290.00 plus VAT, the benefits of the device are reflected in the cost and this is going to be a sticking point with some. However, Boston states that the schedule of competitive prices which they provide, shows the BISON to be by far the lowest priced tool at their high power range.

The BISON is an impressive piece of kit, very well thought out and well made. The fact that the heating electronics and cooling fans are separate from the inductor probe, which is connected by a long cable, means you can work in tight spaces and manoeuvre the probe into many angles, making it easier to work under cars and remove the most stubborn of bolts. It saves time, effort and, above all, is safer, with the handheld part lighter and therefore easier to work with. The LED lights at the front are a big benefit and the LED status light on the device itself means you won't be forgetting it is on when you leave the workshop for the night.

    A job I was recently asked to look at had a bit of an odd symptom; it would run (apparently quite well), as long as the camshaft position sensor was unplugged. The previous history on the vehicle, a 2009 2.5 TDI VW Transporter, was very limited. During my initial inspection, I noticed that the vehicle was suffering from a slightly extended cranking time, which is quite normal for a cam sensor related issue, as the engine ECU cannot easily calculate which TDC is which.
