New alternators, starter motors and regulators from Dubai for export

The family is four kinds of part. Alternators charge the battery and feed the car's electrics once the engine runs. Starter motors turn the engine over until it fires. Regulators hold the alternator's output at a steady voltage. The fourth kind is the small sensor that gives the engine computer the battery readings it controls charging with. Wikipedia says modern designs dispense with a separate regulator and leave voltage control to the engine computer, so a regulator line is quoted only where the maker sells one.

Every line is a complete new unit with its label. Batteries are not on this list at all, because carriers treat lead-acid batteries as dangerous goods and they stay out of every export quote. The crankshaft and camshaft sensors that read the engine's speed belong on our ECU page, where the module they feed is explained. The table shows what must agree on each part before a person can quote it.

Trade tables often cite heading 8511, ignition and starting equipment, which the UAE reported at US$223.7 million of exports in 2023. The sub-headings tell a plainer story. Spark plugs were US$153.3 million of it, 69%. Starter motors were US$19.3 million and generators, the line customs use for alternators, US$20.4 million. Coils, parts and other equipment made up the rest. The whole-heading figure makes alternators and starters look more than five times larger than they are.

Saudi Arabia is the real destination for them. It took US$7.6 million of starter motors, 39% of the UAE's starter exports, and US$8.3 million of generators, 41%. Iraq took US$0.3 million of starters and US$0.7 million of generators, 1.7% and 3.2%. Both sets of figures are UAE-reported 2023 values from UN Comtrade, the latest year the UAE has filed.

Pakistan and Egypt look large under the whole heading, at US$10.3 million and US$9.2 million. Spark plugs and parts explain most of it. Of Pakistan's total, spark plugs were US$5.2 million and parts of the equipment US$4.0 million, against US$0.17 million of starters. In Egypt, spark plugs were US$8.8 million, and starters US$0.02 million. We therefore do not present either country as an alternator market, and a quote does not depend on that reading.

Almost all of it is goods passing through. Re-exports were 99.8% of starter value and 98.6% of generator value, so the units sold in Dubai are mostly made elsewhere. At about US$4.9 a kilogram the generators line is also cheap by weight, which suggests it holds more than new car alternators. Comtrade does not separate new from used, so that is our reading and not a published finding.

Voltage comes first. Most cars and light trucks run 12 V, while Wikipedia's article on automotive batteries says heavy trucks and earth-moving equipment can run 24 V, with two batteries in series. A quote states the voltage on every line, and a 24 V unit is never offered for a 12 V vehicle. Denso's September 2023 news added three heavy-duty starters linked to 15 OE numbers, for road haulage among other uses, a reminder that heavy-duty units form a separate list.

Output is next. Wikipedia gives typical passenger-car and light-truck alternators as about 50 to 70 A, semi-trucks as 140 A and buses or heavy equipment as up to 300 A. A retail listing for a Toyota-fit alternator shows 110 A, and a listing for another Toyota number shows 100 A, so the amps differ by number even within one make. We quote against the amps printed on the old unit's label, and a person tells you when the unit offered has a different output.

The pulley is the detail buyers forget. The 110 A listing describes a freewheel pulley of 58.0 mm with six ribs, an M6 B+ terminal and three mounting holes. A different diameter or rib count changes how the belt runs, and Hella's workshop advice tells fitters to check the alternator freewheel clutch and pulleys for smooth running, play and alignment. Photograph the pulley face-on and from the side, with the label in the same picture if you can.

Cross-reference lists run long. The listing for the 110 A unit names seven Denso numbers, from 1042102800 to 1042105491, and six Toyota numbers beginning 27060, beside references from more than a dozen other brands. Denso's September 2023 news item links its new passenger-car starter and alternator references to 18 OE part numbers, covering 89 models and almost 1.7 million vehicles. One maker number can serve many cars, and one car can take several maker numbers.

That is why we ask for two numbers and not one. Send the number on the old unit's own label, the carmaker's number if you have it, and the VIN. A person checks the pair against each other and against the engine code, and tells you if the label number alone would have allowed a wrong fit. Photographs of the label, the pulley and the plug cost you nothing and settle most queries before a quote is written.

Denso's technical manual sorts starters into pinion shift, reduction and planetary types and alternators into conventional, Type III and SC types. The names show that a starter for this engine can hide several designs, and the label number picks one. Regulators follow the same rule: retail listings key them to the alternator's Denso number, such as 104210-3050 to 104210-3052, so a regulator is ordered by the alternator's number and not by the car.

Genuine is the carmaker's own unit in its box; the Toyota numbers in the listing above begin 27060. OE-brand means the firm that supplies the carmaker sells the unit under its own name, and Denso's 2016 technical manual claims OE coverage of Toyota and of Ford, Opel, BMW, Fiat and Land Rover. Quality aftermarket is a branded replacement made to the same pattern. We hold no measured Dubai price for an alternator or a starter, and each quote gives a price for every grade it can supply.

Bosch, Valeo and Mitsubishi Electric are names buyers ask for beside Denso. The public pages we read say Mitsubishi Electric lists charging and starting products among its automotive equipment, Valeo supplies automakers and the aftermarket, and Bosch has made generators since 1914. They do not say which Toyota or Nissan number each firm supplies. A person therefore checks the number and never the logo, and calls a line OE-brand only when the maker is known to supply that carmaker.

The word new needs checking in this part family. Exchange units, sold against the return of the old one, trade under famous names, and cross-reference lists mix their numbers with new ones: the listing above groups some numbers under the heading Bosch Exchange. Denso's manual draws the contrast, saying its units are all new in box, with no remanufactured units and no core surcharge or returns policy. We supply no exchange or remanufactured unit and ask for no core, so the price quoted for a new unit is the whole price.

Saudi Arabia is the measured market, at 39% of the UAE's starter exports. Its SASO regulation for auto spare parts names brake linings, filters, radiators, mirrors, lamps and suspension among its categories. The list we read does not name alternators or starters, and the SABER certificates sit with the Saudi importer in any case, so ask your importer whether a given line needs one before you order.

East African and Zimbabwean fleets can order by engine code. Our research notes, an analyst's judgement and not a maker's statement, read starters and alternators as units that usually fit right-hand-drive versions of the same engine, which suits Kenya, Tanzania, Uganda and Zimbabwe. A Toyota Hilux, Hiace or Isuzu truck fleet can therefore send one list covering its starters and alternators beside filters and brakes, quoted by label number.

They are heavy for their size, the opposite of a radiator. Starters shipped from the UAE to Saudi Arabia in 2023 averaged about US$13.9 a kilogram, US$7.57 million over 543 tonnes, so a carton is dense and your agent's weight charge will decide the bill, not its volume charge. Keep every unit in its maker's box with the label outward, put heavy boxes at the base, and keep terminals and plugs capped as boxed.

The paper must follow the cartons. The packing list gives each line's label number and quantity exactly as the box shows them, so your agent and your clearing agent can match one to the other. A Deira consolidator's card that we read starts at 30 kg, at AED 38 a kilogram for Nairobi, which means a single alternator pays for 30 kg. A list of many units fills that minimum properly, and that is the reason for the trade-size rule.

Send the VIN or the engine code, the label number of the old alternator or starter, and photographs of the label and of the pulley or pinion. Add the voltage and amps if the label shows them, the quantity, the grade you prefer, the country the parts go to and the name of your cargo agent. Six or more parts on one list is the working minimum, so a fleet restock for several vans suits.

A person replies on WhatsApp with each line, its grade, its brand and the number it was matched to, and marks as declined any line that label and VIN could not support together. Payment is arranged with that person in the same chat. Nothing is collected until you and your agent have agreed the packing and the paperwork: the commercial invoice with a customs code for each line, the packing list and the certificate of origin.
