The Jarama is the rarest and most understated of Lamborghini's front-engined V12s: a compact 2+2 coupe built from 1970 to 1976 as the Jarama GT and the more powerful Jarama S, often called the GTS. This guide joins our model-by-model series alongside the Espada, Miura, Countach, Diablo, Murciélago and Gallardo guides.
The Jarama shares its 3.9-liter L 403 V12 with the Espada, and Lamborghini covered both cars in one factory workshop manual for that engine, written in Italian for the factory's own technicians. It sets two filter intervals that every Jarama owner should know: a new oil filter cartridge every 5,000 km and new air filter cartridges every 10,000 km, along with the ignition, valve and cooling settings listed below.
A short disclaimer before the table: the engine figures come from the factory workshop manual for the L 403 engine, which covers the Espada and the Jarama together, and the capacities come from a period Lamborghini technical-data sheet for the classic V12 range. The engine manual gives no oil-change, gearbox, differential or brake-fluid interval, so those items are marked unverified. US-market engines received their own ignition and emissions equipment, which the manual covers separately, so confirm settings for a US car by chassis number. Parts fitment comes from the Lamborghini parts catalog we carry for US-market cars, checked against each product page. The manual lists the engine at 350 CV; the later Jarama S was rated higher, so confirm settings for an S by chassis number.
Distances are those printed in the factory workshop manual; mile figures are rounded conversions.
| Service item | Interval (factory workshop manual, L 403 engine) | Notes | What's needed |
|---|---|---|---|
| Service schedule and handbook | The full schedule is set in the owner's handbook supplied with each car (unverified). The engine workshop manual sets the filter intervals below | We do not currently list a Jarama handbook; email us and we will look for one | Email us with your chassis number |
| Engine oil filter | Replace the cartridge every 5,000 km (about 3,100 miles) in any case | The manual lists the cartridge as Lamborghini 1501188, the same number as the Bullstuff part | Oil filter cartridge 001501188 with seal 001501128 |

| Valve clearance | Check interval unverified | 0.25 mm intake and exhaust, set cold. The camshafts are chain-driven | Workshop procedure |
| Coolant | Change interval unverified. The manual asks for the system to be drained and refilled with antifreeze mix before freezing weather | 14 liters (technical-data sheet). Agip F 1 Antifreeze, 20 percent for −10 °C up to 45 percent for −35 °C. Thermostat opens at 83 ± 2 °C, fully open at 92 °C | Antifreeze to your handbook's specification |

The Jarama's engine manual asks for a new oil filter every 5,000 km whatever else is done, so keep a spare cartridge and seal on the shelf.
Most Jaramas now cover few miles, and oil, coolant and brake fluid keep aging while the car sits. Owners and specialists commonly service them on time as well as distance. Your handbook will say which interval applies.
With so few cars built, Jarama parts are often shared with the Espada and Miura. That helps availability, but it also means the right part can depend on the chassis number, so have it ready when you order.
For a broader walk-through of filters, brakes, plugs and fuel pumps, see our routine maintenance guide.
Please confirm every interval against your own handbook before you book the work; the factory manual we used covers the engine, and your handbook sets the rest of the schedule.
Bullstuff, also known as Lambostuff, is No Limits Solutions LLC in Xenia, Ohio.
