The R129 500 engine is a hot motor. Normally a car will work best at 80 degrees Celsius, but the design of this motor is so it will work at best at 100 degrees Celsius. So on 90 degrees there is nothing wrong. The fan should go running about 100 degrees and let the engine cool of on that temperature. Only higher temperature above 100-110 degrees will cause trouble. My car is normal to have it in 15 minutes to go to 90 degrees, and when I stock in traffic jam with outside temperature from about 30 degrees, like this afternoon, the temperature rises within a minute to 100 degrees and the fans are started to work. Then the temperature stays steady and when I can drive harder and the wind blows true the radiator the temp drops to 90-95 degrees. So if everything is working well, 100 degrees is no problem. In the beginning I also was afraid it was wrong, but they explained me that it is normal and that the cooling fluid in a closed circuit not is boiling at 100 degrees, but at 120 degrees. It is the principle of the fast boil dinner pan. But then it is wrong with the engine!!

All tires become little cracks on the inner side of the tire, so you even cannot see it. *In Holland they have a lot off speed limit bulbs who are just touching the inner side of the tire.

We could all spend weeks or even years on cars and vehicle tyre pressures. The pressures are dependent upon tyres, vehicle weight, vehicle weight distribution, how much stuff we manage to fit in, number of passengers carried, and where all this is carried, required handling, road construction, road conditions, road 'banking', vehicle steering engineering, fuel economy etc etc. All good engineering stuff! We presently have some 7 cars and 4 motorcycles/ scooters (including a Piaggio MP3!). Like many car/ motorcycle enthusiasts, I have possibly owned some 100+ vehicles in my lifetime (so far) and driven a lot more vehicles in NZ and other countries. In winter, I tend to run the cars/ motorcycles at 32 psi - yes all of them (front and rear), to give a bit of grip on the roads just in case. In Autumn (fall), Summer and Spring, all the vehicles are pumped up to 36 psi. Sorry about the psi bit, but in New Zealand we are meant to use kilopascals for the last 30 years - our beautiful country uses all metric parameters, but we still tend to use psi as the US uses psi! I run a variety of tyres from Pirelli PZ0, through Bridgestone Potenzas (my overall favourite tyres) and currently Kumho's on the R129 ( believe it or not my second best favourite brand). I also have continentals, Firestone Firehawks and Michelins on the cars. In NZ we seem to be fraught with a variety of imported Asian tyres that I can hardly pronounce the names of! Many tyres are the very dangerous mud and snow tyres that should be banned in NZ - another story! Our motorways here and very different from the freeways overseas. Our roads generally use a rougher chip seal, and most of all of our corners are banked to allow better handling/ cornering. Our secondary roads are narrow sometimes, not too dissimilar from English country roads. We have quite a few 'gravel' roads as well. Note that low profile tyres do not track too well on gravel, so if I am back country roads for a long trip, I often exchange my 18 inch Potenzas on the W123 with the traditional 123 Mag alloy Merc wheels fitted with Bridgestone 205/65/15 tyres. So in brief, being a simple bloke that is not capable of multi-tasking, unlike our female counterparts, I put in 36 psi summer, autumn and spring and 32 psi winter. Those horrible space savers in the Japanese vehicles have to be run at about 70 psi though - short distances only. Cold in NZ at present as it is our winter - about 4 degrees C here today. Acquired a chill 3 weeks ago and have had a dowse of influenza (not the swine type!) - main possible cause - driving the R129 with the top down, outside temp at about 2 degrees, and not having enough gear on! We have our National Mercedes Benz AGM in Picton (top of the North Island) next week so will have to get my woollies out as we will be in the R129 with the top down heading across on the ferry. The greater Picton area has about 150 wineries within a 100 km radius, so I wonder what else we will be doing...... Have a great week.

All tires become little cracks on the inner side of the tire, so you even cannot see it. *In Holland they have a lot off speed limit bulbs who are just touching the inner side of the tire. It is even dangerous, now I have no problems with 2.8 bar rear and 2.5 in front.

We could all spend weeks or even years on cars and vehicle tyre pressures. The pressures are dependent upon tyres, vehicle weight, vehicle weight distribution, how much stuff we manage to fit in, number of passengers carried, and where all this is carried, required handling, road construction, road conditions, road 'banking', vehicle steering engineering, fuel economy etc etc. All good engineering stuff! We presently have some 7 cars and 4 motorcycles/ scooters (including a Piaggio MP3!). Like many car/ motorcycle enthusiasts, I have possibly owned some 100+ vehicles in my lifetime (so far) and driven a lot more vehicles in NZ and other countries. In winter, I tend to run the cars/ motorcycles at 32 psi - yes all of them (front and rear), to give a bit of grip on the roads just in case. In Autumn (fall), Summer and Spring, all the vehicles are pumped up to 36 psi. Sorry about the psi bit, but in New Zealand we are meant to use kilopascals for the last 30 years - our beautiful country uses all metric parameters, but we still tend to use psi as the US uses psi! I run a variety of tyres from Pirelli PZ0, through Bridgestone Potenzas (my overall favourite tyres) and currently Kumho's on the R129 ( believe it or not my second best favourite brand). I also have continentals, Firestone Firehawks and Michelins on the cars. In NZ we seem to be fraught with a variety of imported Asian tyres that I can hardly pronounce the names of! Many tyres are the very dangerous mud and snow tyres that should be banned in NZ - another story! Our motorways here and very different from the freeways overseas. Our roads generally use a rougher chip seal, and most of all of our corners are banked to allow better handling/ cornering. Our secondary roads are narrow sometimes, not too dissimilar from English country roads. We have quite a few 'gravel' roads as well. Note that low profile tyres do not track too well on gravel, so if I am back country roads for a long trip, I often exchange my 18 inch Potenzas on the W123 with the traditional 123 Mag alloy Merc wheels fitted with Bridgestone 205/65/15 tyres. So in brief, being a simple bloke that is not capable of multi-tasking, unlike our female counterparts, I put in 36 psi summer, autumn and spring and 32 psi winter. Those horrible space savers in the Japanese vehicles have to be run at about 70 psi though - short distances only. Cold in NZ at present as it is our winter - about 4 degrees C here today. Acquired a chill 3 weeks ago and have had a dowse of influenza (not the swine type!) - main possible cause - driving the R129 with the top down, outside temp at about 2 degrees, and not having enough gear on! We have our National Mercedes Benz AGM in Picton (top of the North Island) next week so will have to get my woollies out as we will be in the R129 with the top down heading across on the ferry. The greater Picton area has about 150 wineries within a 100 km radius, so I wonder what else we will be doing...... Have a great week.
