Eventually the windscreen jets stop squirting, chances are they have just run out of water, lets fill it up.

Finding The Engine Number – 451
Petrol Models Only The petrol 451 of all types, turbo or non turbo had the same engine number location. Thankfully, it's 879% easier to get to and 423% easier to read than the previous model's engine. As you look at the lower right hand side of the engine block, just...
Finding The Engine Number – Roadster
Where Is The Engine Number? This is one of those strange questions that I get asked on a fairly regular basis. I didn't understand why it was necessary at first until I was told the reason. Apparently, in some countries, if you import a car, they want to know...
Fit A Boost Gauge
Fit an aftermarket boost gauge to your smart!
Fit A Cycle Valve
The older, lower powered smarts had a mechanical boost controller instead of the electronic boost controller in the 61bhp models. Fitting this part is cheap and quite easy.
Fitting 451 Foglights
The foglights on the fortwo 451 are much better than the old fortwo foglights.
Fitting A Better Horn

Fitting Brake Hoses

Personally I never thought the smart brakes were too bad but I have heard many complaints about their effectiveness. Changing the discs and pads go part way to sorting this problem out, changing the hoses can increase the feel and stopping power of the brakes.

Fitting New Reluctors

How to fit reluctor ABS rings both ways
Fixing A Windscreen Chip



The worst thing about winter is that the roads get gritted. You are behind a gritting lorry and you can hear your car getting dashed with rock salt. The next problem is the grit and salt being kicked up and damaging your windscreen. If you leave a crack like this, it...
Fixing The Rear Panel Clips
Another great one from Shadow. I don't know about you but personally I find the rear panel clips a bit weak and snap all to easily. Yeah they are cheap but why not fix the ones you have for good.
