Renault Trucks 629, 630, Torino Coupé ZX, Grand Routier Repair Manual

You are staring at a 52-page factory manual that was never meant to leave the dealer network. I’ve seen too many DIY guys buy a third-party “service guide” off some website and then wonder why their timing is off or the brakes feel spongy. That’s because the aftermarket stuff leaves out the real numbers – the clamping loads, the ignition timing, the actual wheel cylinder bore. This is the binder that Renault Argentina handed to their own line techs. It covers the 629 sedan and the 630 Coupé ZX, plus the Grand Routier trim. If you are wrenching on one of these inline-four Rodeo blocks or the Torino-platform chassis, you need this document on your bench, not a photocopy from a buddy.

Engine Overhaul: Timing and Camshaft Specs

Chapter B – MOTOR (page 2 in the index) takes you through the entire engine: distribution, camshaft, carburetor, air filter, cooling system, and belts. The manual calls out the valve timing marks and the camshaft endplay checks you need when you pull the head. No asterisks, no “check service bulletin.” The carburetor section alone saves you burning a weekend trying to chase an air-fuel ratio that’s off because the throttle linkage was reassembled wrong. For the Grand Routier and Torino Coupé ZX, the crankshaft pulley removal sequence is spelled out with the required puller – no guessing.

Does This Manual Cover the Electrical System?

Yes, and it does it right. Section C – EQUIPO ELECTRICO Y ENCENDIDO dedicates pages to the alternator, ignition coil, distributor, spark plugs, fusible links, automatic interrupters, and the complete front wiring harness (right side). If you are chasing an intermittent no-start on a 629 or 630, the factory wiring diagram for the ignition switch and starter interrupt is in there. The manual also covers the light switch horn relay and the central instrument cluster cover – not something you get from a generic diagram. I’ve seen techs fry a 1970s Renault distributor because they used aftermarket coil resistance values. That won’t happen with this document.

7 Major Systems Detailed in 52 Pages

Let’s run the list from the table of contents: A – Generalidades (vehicle ID, safety belts, jacking points, fuel cap), E – Gearbox (characteristics), G – Steering (column and shaft), H – Front axle, J – Rear axle, K – Wheels and tires, M – Brake system (wheel cylinders, drum and hub, parking brake), N – Body (glovebox, center console, instrument panel, roof lining, bumpers), P – Climate control (heater and A/C). That’s nine chapters, but the transmission and drivetrain are packed into E and J. For a Manual Transmission rebuild, the gearbox characteristics page gives you the bearing preloads and shift fork clearances. Clutch alignment procedures are covered under Manual Transmission in the generalities section.

Understand the Brake System Before You Touch It

The brake chapter (M) is where most DIY guys get into trouble. The manual lists the wheel cylinder bore diameters and the drum brake shoe adjustment for both the 629 and 630. It also covers the parking brake cable routing and the hub/drum interface. If you are swapping drums on a Torino Coupé ZX, the factory says to check the runout on page 4 (yes, page 4 of the chapter) – I won’t tell you the number because it’s in metric and you have to read it yourself. That’s the point: you get the real spec, not an approximation.

Body and Climate Control: Factory Trim and A/C

Section N – CARROCERIA includes the glovebox removal, center console, instrument panel, roof lining, and bumpers. For the A/C and heater, section P – CLIMATIZACION covers the climatizer unit and air conditioning components. No diagrams of the evaporator? Actually yes – the manual includes the expansion valve location and the blower motor circuit. That matters when you are retrofitting an old system or chasing a refrigerant leak.

Source Authenticity: Why This Is the Only Manual You Should Use

This is a digital reproduction of the original Renault Argentina M.R. 63. It is not a generic aftermarket compilation. The OEM publication number, the Spanish text, the page numbers – all match the factory print. I have seen third-party “data” that claims the 629 Grand Routier uses different ignition timing than the Coupé ZX, and it is wrong. This manual shows the same values for both because the engine is identical. When you pay for this, you get the exact same 52 pages the dealer techs had. No reprints with missing sections, no “reformatted for clarity” that actually drops torque tables.

If you own a Renault Trucks Fuego, R18 Repair Manual – 1979+ Autodata 193 Pages, you already know the value of OEM data. This 629/630 manual pairs well with the Renault Trucks Clio 1999 Repair Manual – Factory Specs & Step-by-Step for newer models. For heavy-duty work, the Renault Trucks B80A BB0C BB0D BB0E CB0A 1997 Repair Manual 3565 Pages covers the truck side. But for these classic passenger car platforms, this is your only factory source.

Is the manual in English?

No. It is in Spanish.

Will this manual tell me the exact torque for the cylinder head bolts on the 2.2L engine?

Yes, it does. The engine chapter (B) includes the torque sequence and value for the cylinder head, camshaft bearing caps, and intake/exhaust manifold. It also specifies the angle-tightening step if applicable. You will find the exact number on the same page as the distribution diagram. I won’t quote it here because you need to see it in context with the tightening pattern. That pattern is the difference between a head gasket that lasts 50,000 miles and one that fails in 5,000.
