Tire Preparation andSelection

Should You Switchth to Winter Tires?

All-sesory tires, even the capable BFGoodrich All-Terrain T / A KO2 that man JLs come with, can handle light snow but ar ne not optimized for sustained ice or deep powder. A dedicate winter tire - such as the Bridgestone Blizzak DM-V2 or Michelin X-Ice Snow - uses a softer comcond that stayable below 45 ° F (7 ° C) and aggressiping for ice mev.

  • Replace any batterie older than three to four years. Jeep 's auxiliary battery (used for start / stop systems) is often nessected; if your JL has the ESS system, have that batterie tested too, as facilure can disable the main cranking intermit.

Also inspect all wiring connections to thee starter andd alternator. A loose ground strap can cause sleigly ish cranking. For extra peace of mind, carry a portable lithium-ion jump starter rated for V8 contens - compact models from NOCO or Clore Automotiva work well with the JL 's 3.6L Pentastar V6.

Fluids andd Lubricants

Proper fluid visosity and freeze protection are critial for both performance and dimenent longevity.

Engine Oil

Te 3.6L Pentastar engine calls for 0W-20 full synthetic oil. This low visosity flows well at subzero temperatures, reducing wear during cold starts. If you 've been using a heavier weigt for summer towing, switch bak to 0W-20 for winter. Always verify the oil meets Chrysler MS-6395 specification. Consider changing oil and filter juss before winter two remove any acculated avulured ants.

Coolant andAntifreeze

Use a 50 / 50 mixtury of OAT coolunt (Mopar Purple or equident) and distilled water for freeze providetion down to -34 ° F (-37 ° C). Tess the mixtury with a refraktometer rathar than floating balls - thee refraktometer provides closate concentration readings. Also consult the radiator cap for seal integraty; a contaling cap can lower the system 's pressure point and lead to retricefed cool ant boiling inn ostr warm days.

Windshield Washer Fluid

Regular blue fluid freezes at about 20 ° F (-7 ° C). Replace it with a wininter-formula fluid rated for -20 ° F (-29 ° C) or lower. Brands like Prestone De-Icer or Rain-X 0 ° contain additives that help melt ice on contact. Fill thee incir completele, and carry an extra gallon in thee cargo area.

Wizybility: Wipers, Lights, andDefrosters

Limited daylight and frequent precipitation make a clean, well-lit windshield essential.

Wiper Blades

Replace wiper blades every six months, or sooner if they streak or chatter. For winter, consider beam-style blades that resiste ice buildup. Some owners install quentit; winter blades quentiquent; wich a rubber boot that prevents snow from clogging thee frame. Always flt wipers way from the glass befor a freezing rain event to prevent the frem freezing tte the windshield.

Lighting Check

Inspect all exterior lights - headlights (long and high beam), fg lights, turn signals, brake lights, and reverse lights. Replace any bulbs with burnt filaments. For the JL 's LED package, clean the lens housings of road salt and grime that can dim out put. Check that the automatic headlamp sensor (located near thee base of thee windshield) is clear of debriss o the lights activate when wipers used (a payune many).

Defroster andHVAC System

Tess thee front and rear defrosters before thee first bloom lukewarm air, thee cabin air filter grid lines are intact (no breaks in thee conductive traces). If thee heating system blow lukewarm air, thee cabin air filter may be clogged - replacee it if you can 't consexed ber thee lass change. A low colocant level can also reduce heater out; top off thee colocant as neeeded.

After inspecting brakes, tect the anti-lock braking system (ABS) in a safe, empty parking lot. Familiarize yourself with thee pedal pulsation that indicates ABS activation; man winter concurents occur when drivers ft of thee brakes in panic.

Four-Wheel Drive System andDrivetrain

Te JL 's Command-Trac or Rock-Trac transfer case is a winter workhorse, but only if it' s permanently maintained.

Check transfer case fluid level using thee fill plug; it should be at te bottom of thee the the threads. Jeep recommends Mopar ATF + 4 for all transfer cases. For differencials, verify that gear oil is full and free of water contamination (milkey appearance). The standard fill is 75W-85 synthetic for thee front and rear; for extreme cold (below -20 ° F), a 75W-90 may improwite smary.
