Arctic Cat ATV 150 2008 Service Manual

I’ve been turning wrenches for 28 years, and I can tell you straight—buying a cheap aftermarket manual for an Arctic Cat ATV 150 is throwing money at a headache. This Arctic Cat ATV 150 2008 Service Manual is the OEM document you put on the bench when you want to keep that little engine running without second-guessing every torque value. 101 pages of factory data, not some photocopied reprint from a third party.

Arctic Cat ATV 150 2008 Service Manual: General Information and Torque Specs

Section 1 starts with General Specifications and Torque Specifications. You get tightening torque for general bolts in ft-lb, plus a conversion table for N-m if you work in metric tools. Page 1-2 lists the critical values you need during reassembly. Aftermarket manuals often leave out the torque sequence—this one prints it in the table. If you are rebuilding the top end, you need those numbers. I’ve seen cylinder heads warped because someone used a generic spec from the internet. Don’t be that guy.

Does This Manual Cover the Fuel and Cooling Systems?

Section 4 is Fuel/Lubrication/Cooling. That means carburetor adjustments, fuel line routing, oil change intervals, and cooling system bleed procedures. The manual includes ▲ WARNING symbols for hot coolant and fuel vapors. If you skip the cooling system refill procedure, you risk air pockets that cause overheating. The manual walks you through the correct order. Every ATV 150 owner who plans to do his own service should have this section flagged.

3 Reasons to Stick with OEM Documentation

First, the torque specs in this manual are factory-correct for the 2008 model year. Second, the wiring diagrams in Section 5 (Electrical System) are actual Arctic Cat schematics—not redrawn by some aftermarket outfit that gets pin colors wrong. Third, the break-in procedure on page 1-2 is specific to the ATV 150. Aftermarket reprints often use generic data that does not match the engine’s ring end gap spec. This manual also covers the Engine/Transmission in Section 3, which includes disassembly, inspection, and assembly instructions for the engine and Manual Transmission.

Engine and Transmission Disassembly Sequence

Section 3 is where the real work happens. The manual walks through removing the cylinder head, checking ring end gap, and torquing head bolts in the correct pattern. I’ve fixed engines where someone skipped the sequence and then wondered why the head gasket blew after 50 miles. The manual also covers Suspension (Section 7) and Steering/Frame (Section 8). For Drive System details, Section 6 has the belt removal and installation procedure. If you need more depth on drive components for larger models, look at Arctic Cat 500-650 V-Twin Service Manual Section 6 Drive System – it uses the same factory approach. That’s one of the reasons I keep a shelf of OEM books: consistency.

This manual gives you the full breakdown for the ATV 150. If you also own other Arctic Cat models, the Arctic Cat 250, 400, 500, 300, 650 Service Manual – OEM Tune-Up Data has similar factory tune-up specs. And for the 2011 version of the ATV 150, grab the Arctic Cat ATV 150 2011 Service Manual for updated wiring.

Electrical System: Factory Wiring Diagrams

Section 5 of the Arctic Cat ATV 150 Service Manual contains the electrical system diagnostics. You get wire colors, connector pinouts, and component locations. This is not a generic wiring diagram—it’s the OEM version used by Arctic Cat service centers. Trace a short without it and you will waste hours. The manual also covers Controls/Indicators in Section 9. One more thing: newer machines with emission controls have Catalytic Converters, but the 2008 ATV 150 does not use one—the manual clarifies that in the exhaust section.

101 pages. That’s how many pages of factory data you get.
