VG1540010014 HOWO Oil Cooler Cover

The VG1540010014 HOWO Oil Cooler Cover is a special protective and sealing part-only for SINOTRUK HOWO heavy-duty trucks. Let me tell you, I've been fixing trucks for over a decade, and nothing's more annoying than aftermarket covers. Last month, a guy brought in a HOWO with a generic cover: bolt holes were off by 5mm, he'd drilled new ones, and it still leaked oil. But this OEM one? Hold it up to the oil cooler on a HOWO A7 or T7H, and it lines up like it was born there. No forcing, no guesswork-just a clean fit.

It's not just a "lid" either; it does two things that keep engines from dying early. First, it wraps the oil cooler tightly. If dust, road grime, or even rain gets into the cooler's tiny tubes, the oil passages clog fast. I've seen trucks overheat because of that-oil can't cool down, so the engine runs hot, and next thing you know, the driver's stuck on the highway waiting for a tow. Second, it seals the cooler so oil doesn't leak. Even a small leak adds up: I had a truck come in with 2 liters less oil than it should have, all because the old cover's gasket was shot. Low oil = seized engine-total nightmare.

It's built to SINOTRUK's OEM standards, so the cut's sharp. Line it up with the cooler's flange and bolt holes, and it's perfect-tighten the bolts, and no oil seeps out. The material is either tough engineering plastic (usually PA6+GF30, with glass fiber to stop it from breaking) or aluminum alloy. Both handle heat like a champ-even when the engine's running at 120°C on a summer day, they don't warp or crack. And they don't get eaten by engine oil or coolant-unlike those cheap plastic covers that turn soft after 6 months.

The best part for us mechanics? It already has bolt holes drilled. No need to measure twice and drill once (I've messed up covers that way before-total waste of time). Some versions even come with a rubber gasket pre-stuck no fumbling to line up a loose gasket while holding the cover. Whether you're swapping an old, cracked one (I've seen covers split down the middle from heat) or just doing a tune-up, this one keeps the HOWO's oil cooling system working like it did when the truck was new.

Applicable Model: SINOTRUK HOWO heavy-duty trucks. Specifically fits HOWO A7, T7H, T5G HOWO that uses the matching oil cooler. If you're not sure, just check the truck's service manual (the part number's usually on the old cover too) or call the parts shop. They'll tell you in 2 seconds if it fits.

Part Function: Protects the engine's oil cooler and seals it to stop oil leaks. Simple job, but if it fails, you're looking at big repair bills. Material: - Option 1: Glass fiber-reinforced polyamide (PA6+GF30) – I've dropped these from waist height, and they still don't break. Good for regular use-regional deliveries, short hauls, anything not super extreme. - Option 2: Aluminum alloy (ADC12) – cools down fast and doesn't rust. Perfect for trucks in hot places (southern China's summer is brutal) or mining/construction-those trucks take a beating, and aluminum holds up better.

Operating Temperature Range: From -40°C to +120°C. I've seen these work in 30°C winters up north (oil gets thick, but the cover still seals) and 40°C summers down south-no issues at all.

Sealing Performance: No oil leaks. They test it to handle 0.8 MPa of oil pressure even when the engine's hauling a full load up a steep hill, it won't seep. I've never had a customer come back complaining about leaks with this one.

Dimensions: Roughly 210mm long, 150mm wide, 45mm tall. Exactly matches the original cooler's flange-you don't have to trim it or bend it to fit.

Weight: About 0.35 kg for plastic (light enough to hold with one hand while bolting) and 0.8 kg for aluminum (still easy to handle alone). Mounting Type: Bolt-on. Uses standard M8 or M10 bolts-you probably have these in your toolbox. No special hardware (those are always a pain to track down). 4 to 6 bolt holes, depending on the cooler. Certifications: Meets SINOTRUK's OEM rules. Also passes ISO 9001 and IATF 16949-so it's not a cheap knockoff that'll break in 6 months (I've had those-they're more trouble than they're worth).

Fits HOWO perfectly: This is the biggest win. It's made just for HOWO, so bolt holes line up 100%, and the seal hits exactly where it needs to. No tweaking, no forcing-slap it on, and it's like the factory put it there. That generic cover I mentioned earlier? The customer swapped it for this OEM one, and no more leaks.

Tough & Heat-Resistant: The PA6+GF30 plastic or aluminum alloy lasts forever. I had a HOWO T7H come in with 280,000 km on it-cover still looked new, no cracks, no warping. Compare that to cheap covers: I had one break when I tightened the bolts too hard (not even that hard!). This one takes abuse.

Seals Well & Protects: The precise flange and pre-stuck gasket (when included) make a tight seal. No oil leaks, and it blocks dust, water, and road grit from getting into the cooler. That keeps oil clean and the cooler from clogging the engine doesn't overheat. Overheating's the #1 reason engines die early, so this cover saves big money.

Easy to Install: Mechanics love this. Pre-drilled holes, lightweight-swap the old cover in 15 minutes tops with a regular wrench set. No need for a second person to hold it (unlike some heavy metal covers). The truck's back on the road fast, which makes fleet owners happy.

The VG1540010014 HOWO Oil Cooler Cover is mostly for SINOTRUK HOWO heavy-duty trucks. Here's where I see it most: HOWO A7 (long-haul tractor-trailers that run cross-country. These trucks put 100,000 km a year on, so a durable cover is non-negotiable)

HOWO T7H (heavy-load freight trucks-hauling coal, steel, whatever. Their engines work hard, so the cooler needs good protection)

HOWO T5G (regional delivery trucks-food, packages, daily runs. They're on the road every day, so no time for cover failures)

Other HOWO models with the matching oil cooler. Pro tip: Always check the part number on the old cover before buying. I had a guy buy this for a 2012 HOWO-turns out his cooler was smaller, and it didn't fit. Waste of his time and mine.

Here's when you'll use it:

Replacing Old Parts: If your cover's cracked, warped, or leaking, this is the one. I've replaced covers that got damaged from heat (split open), oil (turned soft), or rocks (knocked a chunk out). This one fixes the problem fast.

Regular Maintenance: When you're doing an oil cooler service-changing the oil, cleaning the cooler-swap the cover too. Old covers might look okay, but their gaskets are usually shot. Save yourself a return trip.

Fleet Upkeep: I work with a logistics company that has 20 HOWOs-they only use this OEM cover. Haven't had a single cover-related breakdown in 2 years. Cheaper to buy OEM upfront than to fix leaks later. Heads up: It won't fit non-HOWO trucks (SHACMAN, FAW, Foton) or HOWOs with different coolers. I had a guy try to force it on a FAW-bent the flange, and it still leaked. Just check first.

Q1: Can this cover fit every HOWO truck model?

A1: No, only specific ones-A7, T7H, T5G are the main ones. Older HOWOs (pre-2015) or special mining versions have smaller/bigger coolers. This cover won't line up. Check the old cover's part number or the truck's VIN (parts shops can look it up) before buying. Don't guess-you'll just waste time.

Q2: How do I know if my oil cooler cover needs replacing?

A2: Look for these three signs-I see them every week: 1. Oil leaks around the cooler. You'll see greasy stains on the cover or engine block. Sometimes oil drips onto the ground when parked-hard to miss. 2. The cover's damaged: cracks (usually from heat), warping (doesn't sit flat on the cooler), or broken bolt tabs (tabs break, cover won't stay tight). 3. Oil temp gauge is high. If the cover's not sealing, dirt clogs the cooler-oil can't cool, so temp goes up. If you see any of these, replace it fast. Waiting leads to engine damage (I've seen a seized engine from this $10k repair bill).

Q3: Is aluminum better than plastic?

A3: Depends on your truck's job-no "best" option: Aluminum: Tougher, cools faster. Good for hot places (southern China) or mining/construction trucks that take abuse. I had a mining truck use aluminum-300,000 km and it is still going. Plastic: Lighter, cheaper. Perfect for regular long-haul/regional trucks. Easier to install alone. Both are OEM quality-pick what fits your needs.

Q4: Does it come with a gasket?

A4: Most versions do either pre-stuck on the cover (super easy, no lining up) or in the box. It's EPDM rubber-handles oil and heat, no problem. If you tear the gasket while installing (hey, it happens-pull too hard), get an OEM replacement. Don't use a generic gasket-they leak in a month. Parts shops have the gasket by number, just ask.

Q5: Can I install this alone?

A5: Absolutely need for help. It's light (even aluminum is 0.8 kg), so hold it with one hand and bolt with the other. Just wipe the cooler's flange first (old oil/dirt ruins the seal). I've installed these alone 50+ times-15 minutes max. No special tools needed.
