How to Winterize a Coyote Grill
Winterizing a Coyote grill is four jobs: clean it, shut off and disconnect the fuel, protect the burners from pests and moisture, and cover it once it is cold. Plan on about 45 minutes, plus a few extra on SL-Series models (for the RapidSear infrared) and on the C3C30 flat top (for the patina).

What you need
- Stiff stainless or brass grill brush
- Plastic putty knife or scraper
- Dish soap, warm water, and a soft sponge
- Microfiber cloths
- Non-chlorine stainless steel cleaner
- High-smoke-point oil and paper towels
- Pipe cleaner or venturi brush
- Breathable, fitted Coyote grill cover
- Work gloves
Step by step
Pick a dry day and run a burn-off
With the lid open and the grill still hooked up, run all main burners on high for 10 to 15 minutes to carbonize food debris. Leave the SL-Series RapidSear rear burner OFF during the long burn-off — infrared elements don't need the long high-heat cycle and the ceramic emitter lasts longer if you treat it gently. If the infrared needs attention, give it its own brief 2 to 3 minute cycle after the main burn-off is done.
Clean the grates and cooking surfaces
Brush the grates, pull them out, wash in warm soapy water, rinse, and dry fully. Wipe stainless rod grates with a thin film of cooking oil before storage. Scrape the flame tamers or pull the ceramic briquette tray for a full wash, then wipe the inside of the hood with a barely damp rag.
Protect a C3C30 flat top for the off-season
The commercial-style gas flat top needs its own storage routine. After the final cook, heat the griddle to medium, wipe on an extra-thick layer of high-smoke-point oil, cool, and wipe off the excess — the heavier film shields the surface from off-season moisture. Do not soap the top; store it oiled, cool, and covered.
Empty and wash the grease management system
Pull the drip tray, scrape it, and wash both the tray and the grease cup with hot soapy water. Dry completely. A tray left full all winter rusts and draws rodents that chew on gas hoses — do not skip this even if the tray looks relatively clean.
Brush the burners and check for nests
Once the grill is cold, brush the main burner tubes lengthwise and clear blocked ports with a pipe cleaner. Shine a flashlight into each venturi tube and look for spider webs or insect nests. Coyote's support KB specifically cites venturi blockage as the first diagnostic for the uneven flames people see in spring — a two-minute check in November prevents the March service call.
Shut off the fuel and burn off the line
Close the propane cylinder valve (or the natural gas shutoff at the supply line). Light the grill with the valve closed and let the burners run until they go out on their own — this consumes the gas trapped in the hose and regulator. Then turn every control knob to OFF.
Disconnect the cylinder or cap the supply line
For propane, unscrew the hose per the Coyote owner's manual, fit the cylinder's dust cap or plug, and set the tank aside. For natural gas, leave the hard line alone and keep the shutoff valve closed. Coyote offers a Gen 2 LP-to-NG conversion kit for 34- to 42-inch C and S-Series grills, but conversions must be done by a licensed plumber — never field-rigged.
Wipe the exterior and inspect the hose
Clean the hood and panels with warm soapy water, then finish with a non-chlorine stainless cleaner wiped with the grain. Flex the gas hose and look for cracks, brittleness, or rubbed spots. Replace anything questionable before storage — Coyote sells a replacement low-pressure hose and regulator connector as a stocked part, and it is far easier to buy one in November than track one down in April.
Cover the grill once it is completely cold
Put a breathable, fitted Coyote cover on only after the grill is cold and dry. Match the cover to the series and mount — Coyote stocks separate covers for 30-inch flat-top built-ins, 30-inch flat-top freestanders, 50-inch hybrid combos, and the smaller portables. Pop the igniter battery out if your model uses one. Move the grill into a garage or covered patio only after the cylinder is disconnected and stored outside.
Common mistakes
- Storing the propane cylinder in the garage. A cylinder in an attached garage, basement, or shed is a leak and fire hazard. Keep it upright, outdoors, in a shaded vented spot — even in winter.
- Covering the grill while it is still warm. Residual heat traps moisture under the cover and causes mildew inside and rust spots outside. Wait until the cook box is cold to the touch before you cover it.
- Running the RapidSear infrared through the winterization burn-off. The rear infrared burner on SL-Series grills is a ceramic element meant for short searing cycles, not long high-heat burn-offs. Clean the main tube burners through the long cycle and give the infrared its own brief cleaning pass.
- Leaving a C3C30 flat top bare over winter. A dry, unoiled griddle surface rusts in weeks. Heat, oil heavily, cool, and cover before storage — the single extra oil layer saves half a day of spring reset work.
- Using a tarp or non-breathable cover. A plastic tarp traps condensation and causes more rust than no cover at all. A fitted, breathable Coyote cover vents moisture and still blocks rain, snow, and UV.
Hands-on tips
- Take a phone photo of the hose routing before you disconnect anything — reassembly in April is painless when you can look at the picture.
- Pop the igniter battery out and label a baggie with the grill model so it does not die in a drawer.
- Write the deep-clean date on a piece of tape stuck inside the cover — it is easier to remember what year you last touched the regulator than you think.
- Drop a silica desiccant tub in the cabinet or under the cover if you are in a damp or coastal climate — it halves the amount of surface rust that forms over winter.
- In spring, run the soapy-water leak check on the hose and regulator before the first cook. Bubbles mean a leak and a trip to the parts list.
- If your C3C30 lives in a coastal or high-humidity climate, consider pulling the griddle top off (if your mount allows) and storing it under a cover indoors — a dry garage wall is friendlier to a cast or chrome griddle surface than any exterior cover.
Questions people ask
Do I need to winterize a Coyote grill if I use it all winter?
No. If you cook year-round, keep up with regular cleaning and a tank-swap routine, but if the grill will sit for a month or more in freezing wet weather, the 45-minute shutdown is worth it.
Can I leave the propane tank hooked up over winter?
Disconnecting is the safer default. Most grill manufacturers, Coyote included, recommend closing the cylinder valve, disconnecting the hose, and storing the tank upright outdoors through the off season.
Can my Coyote grill stay outside in the winter uncovered?
The stainless construction tolerates weather, but moisture collects on the cook box floor, burners, and electronics and causes rust and ignitor failures. A fitted Coyote cover — matched to the series and mount — is worth the money. On the C3C30 flat top especially, uncovered winter storage is the single biggest cause of surface rust spring-one.
How do I winterize a natural gas Coyote grill?
Clean the grill, close the natural gas shutoff valve at your supply line, burn off the gas left in the hose, and cover it. Leave the permanent hard line alone — any gas-line work must be done by a licensed plumber.
Does the Coyote SL-Series RapidSear infrared need special winterization?
Yes, briefly. After the main tube burners run through their long burn-off, give the rear infrared a short 2 to 3 minute burn-off of its own, cool completely, dust with a dry nylon brush, and cover with the rest of the grill. Do not spray cleaner on the ceramic face at any point — it soaks in and takes multiple cycles to clear.
