Maserati at Roberts Aerospace & Automotive

We have had many years experience of 1980s and 1990s era Maseratis - from the earliest Biturbos from '82 to '88, through the well developed third series cars of '89 to '98, and the awesome 3200GT from '99 to '02. We have recently been gaining increasing experience with the 4200GT due to customer demand, and existing customers moving onto the newer car and wanting to stay with us.

As well as the usual servicing and repairs we have developed a few cost-effective solutions to common 3200GT and 4200GT issues with exhausts and brake discs. See below for details.

We are particularly good at diagnosing boost problems with the temperamental MABC boost control system, so if your car isn't scaring you witless, bring it to us, and we'll make sure that it does...

Our Top Tips for 80s, 90s, 00s Maseratis:

1. Change the oil. Use fully synthetic oil, and change it frequently - more frequently than the rather optimistic service schedule if possible. The conditions inside a Maserati engine shred the oil pretty quickly. A non-synthetic oil will clog everything up and trash your engine. To change the oil filter you have to remove the radiator on early cars, and the turbo ducting on later cars, so make sure this has been done properly with a Maserati oil filter.
    
2. The later V8 cars have a 6,000 mile recommended service interval - I remain to be convinced that this is a good thing as they have essentially the same bottom end design as the V6s, but have to handle twice the power. I fear that the recent appearance of end float problems on the V8, but not the V6, is down to extending this service interval. On the V6s, they have a 6,000 mile service interval, but recommend changing the oil at 5,000 Km (about 3K Miles). I would suggest that this be applied to all engines with plain bearing turbos, so, early V8 QPs as well.
    
3. Change the cam belt every three years or 18K Miles. Cam belts deteriorate with time, as well as mileage, so make sure you change them regularly.
    
4. On carburettor cars, the fuel pipe from the plenum chamber wall to the carburettor has to go through a very tight angle, this leads to cracking and leaks, which leads to your car blowing up. Check it and replace it regularly.
    
5. On V6 carburettor cars, the front brake calipers need cleaning out and rebuilding every few years as they're from a BMW 2002 and seize if the car isn't used regularly. They do that on BMW 2002's as well.
   
   
6. Dealer servicing of Maseratis is very expensive. I'm often asked why we're a lot cheaper. Perhaps you should ask the dealers why they're so much more expensive instead? We use original Maserati parts, and the correct Selenia and Tutela oils and fluids on the 3200GT and Agip on the 4200GT. We do not cut corners.
    
7. 3200GT and 4200GT Brakes. These are very expensive. In theory the parts are only available from Maserati, and a full set of discs and pads is around £1500 for parts alone. There are no alternative suppliers, the original supplier is not allowed to supply them to anyone other than Maserati, and there are no reproductions being made. However, after a certain amount of detective work we can now source the pads from the factory that makes them for Maserati and refurbish your discs on custom made tooling for £499, fully fitted. The picture is of a front brake disc refurbished after 72K miles. The refurbishment goes beyond crude "skimming" and will remove all warping, lipping, and rippling. This surface treatment will usually produce a disc to greater tolerance of flatness than when the disc was new and on custom made tooling that was designed only for 3200GT or 4200GT discs, and on a machine more usually employed producing parts for the aviation industry. Rear discs not only have the disc surface treated, but the inner drum brake area is bored to a similar tolerance - so your hand brake will start working again! As the standard pad material is awful and the brakes are prone to fade, or just not working as well as you might expect them to, we will fit Kevlar/Ceramic brake pads which we have found to be vastly superior to the standard items, unless you insist on the original pads, which we will advise against.
    
8. 3200GT Exhaust back boxes. These rot out every few years and are about £900 for the pair from Maserati, plus many hours labour to fit, leaving not a lot of change out of £1200. We are now offering a pair of straight through rear pipes, in stainless steel, with a stylish twin oval rear tip fully fitted for only £699 inc. The modestly increased sound from the engine can only be described as a bonus as it makes the car sound like the 400bhp supercar that it really is. They're also about 30Kg lighter, and looking at what a mess the baffle design inside the standard back box is like, I'm sure they liberate a few more horses. It certainly sounds like it, and owners who have had them fitted by us do report more power and better response.
   
   We also do a more restrained silenced quad tip variety that preserves the look of the car and generates a more muted sound. Its more efficient design than the original Maserati part means that owners of cars that we have fitted these to are reporting improved response and performance. This more complicated system is fully fitted for an all inclusive price of £799 inc for a pair of rear boxes.
   
   We offer similar systems for the 4200GT as well.
   
   
9. Radiators can leak. Not because the radiator is poor - on the contrary, it's extremely robust, but because the lower water pipe into the side tank can crack its joint. The rubber hose that attaches here needs to be removed when you change the cam belt and if the person doing the work is a bit rushed, then wiggling the hose to get it off will put a lot of strain on this joint and it will crack and leak. Having seen a lot of these - especially since the official dealerships apparently cut the number of hours allowed for a cambelt change - we have developed a repair and redesign with a new collar silver soldered into position that gives the joint enough strength to cope with even the most ham-fisted of the official Maserati dealer network, and will fix any leak. The cost for this including the extremely time consuming process of actually removing and reinstalling the radiator for repair is £299. This compares very favourably with getting a new radiator fitted at a dealership which can cost you up to £1K.
    
10. Starter motors have started to become a bit of a problem. As they're not really up to the job, they can suffer from a number of maladies, especially as they sit in the "V" of the V8 which can often fill with water from minor water leaks in the coolant distribution pipes that run under the inlet manifold. All this puts a bit of a strain on a motor originally designed to start a French shopping car (Maserati just changed the gear teeth pitch on the internal gearing). With a new motor from Maserati approaching £400 and the original manufacturer claiming not to make them any more, we can rebuild your old motor for £149 - about the cost of a second hand one. Fitting a starter motor is a more than challenging task, and should you not wish to go through all the hassle of removing the inlet manifold, fuel injection system, and much of the cooling system, we'll be more than happy to do it for you.
     
11. V8 Service intervals. There is much chatter on web forums about service intervals as the factory documentation dictates 6K Mile (10K Km) service intervals, yet the owners handbook seems to suggest 12K Miles (20K Km) intervals. The explanation is that the service regime in the handbook actually mandates a 12K Mile (20 K Km) service AND a 12 month service as well. So, if you were driving 12K Miles a year in a brand new Maserati 3200GT, the first service would be at 6K Miles and about 6 months, then after a year, and about 12K Miles, you would have a second service - thus having two services in a year and two in 12K Miles. The next service would be at 18K Miles, and about 18 months, the next at 24 Months and about 24K Miles. However, most people don't drive their Maserati like a rep's Mondeo and rarely manage 1,000 miles a month. So, a 6K Mile service schedule is good enough. The only service items that are "lifed" on age as well as mileage are the brake fluid (which absorbs water over time) and the cambelt which goes brittle with time. So, change your brake fluid every two years and your cambelt every three years, regardless of how many miles you've done...
