Our Left Engine Bottom Guard Plate is a dedicated protective component for vehicle engines, designed to shield the left side of the engine from road debris, stones, and water splashes. Crafted from high-strength steel or reinforced PP (optional), it boasts 120MPa impact resistance—30% higher than ordinary guard plates.
It prevents damage to engine oil pans, hoses, and sensors, extends engine service life, and suits complex road conditions like gravel roads or rural lanes. Compatible with 95% of mainstream models (sedans, SUVs, pickups), it meets OEM fit standards, features easy bolt-on installation, and offers reliable undercarriage protection for daily driving or off-road use.
We offer two premium material choices: heavy-duty cold-rolled steel (2.5mm thick, tensile strength 650MPa) and reinforced PP+glass fiber (3mm thick, impact strength 180kJ/m²). Steel versions pass 50kg heavy object impact tests (no deformation), while PP versions resist corrosion (1000-hour salt spray test with 0 rust). Both exceed industry standards, making our left engine bottom guard plate ideal for long-term undercarriage protection.
Each guard plate is 3D-scanned from original vehicle undercarriages, ensuring 0.5mm dimensional accuracy—100% matching OEM mounting holes. No drilling or trimming is needed during installation, cutting setup time by 40% vs. universal guard plates. It fits 95% of mainstream models, solving the "ill-fit" problem common in cheap engine bottom guard plates.
The steel version adds a 1mm thick EVA buffer layer between the plate and engine, reducing vibration noise by 25dB and absorbing 60% of impact force from stones or potholes. The PP version features a honeycomb internal structure that disperses pressure evenly, preventing cracking even after 200+ minor impacts. This design effectively protects engine oil pans and sensors.
Strategically placed 8mm diameter heat dissipation holes (12-16 holes per plate) maintain engine undercarriage airflow, avoiding overheating (tests show engine temperature stays ≤95℃ during 2-hour high-speed driving). 15mm wide drainage grooves on the edge quickly drain rainwater or mud, preventing water accumulation and rust—key for automotive engine bottom protection in rainy areas.
Steel guard plates are coated with electrophoretic paint + powder coating (total thickness 80μm), which resists acid rain, road salt, and mud erosion. PP plates are added with UV stabilizers, preventing brittleness even after 3000 hours of sunlight exposure. Both materials ensure a service life of 8+ years, 50% longer than ordinary guard plates.
Two material options are provided - ① Cold rolled steel plate: thickness 2.5mm, tensile strength 650MPa, surface electrophoresis+powder coating (total thickness 80 μ m, salt spray test corrosion resistance ≥ 1000 hours); ② Enhanced PP+30% fiberglass: thickness 3mm, impact strength 180kJ/m ², added UV stabilizer (anti UV aging ≥ 3000 hours), both materials have a density of ≤ 2.8g/cm ³, lightweight and durable.
The overall size (length x width x height) is customized according to the vehicle model, covering 400mm x 250mm x 50mm-700mm x 400mm x 80mm (suitable for sedans SUV、 Pickup truck); The number of installation holes is 4-8 (hole diameter 8-12mm), with a hole tolerance of ± 0.5mm. It is 100% compatible with the original installation position of the vehicle and does not require additional drilling. It is suitable for the installation requirements of the left engine bottom guard plate of 95% mainstream vehicle models.
The steel plate version can withstand a vertical impact of 50kg weight (impact height 30cm) without deformation, while the PP version can withstand 200 times+5kg gravel impact (impact speed 2m/s) without cracking; Overall bending strength: Steel plate type ≥ 300MPa, PP type ≥ 80MPa, can effectively resist the impact of road debris and protruding obstacles on the engine oil pan.
The diameter of the heat dissipation holes is 8mm, the number of openings on a single board is 12-16 (evenly distributed), the ventilation area is ≥ 15cm ², ensuring the heat dissipation efficiency at the bottom of the engine and avoiding high temperature accumulation; The edge drainage groove has a width of 15mm and a depth of 5mm, with a drainage speed of ≥ 50ml/s. It can quickly drain rainwater and mud, preventing water accumulation and corrosion at the bottom.
Standard 8.8 grade high-strength installation bolts (length 20-40mm, quantity matched with installation holes), installation torque requirement 15-25N · m; net weight of single plate: steel plate 1.8-3.5kg, PP 0.8-1.5kg, no additional burden on the vehicle body after installation, and no impact on the vehicle chassis passability (minimum ground clearance reduction ≤ 5mm).
Complies with ISO 11439 automotive protective parts standards and has passed ROHS environmental certification; Design service life: Steel plate version ≥ 8 years, PP version ≥ 6 years. Under daily driving of 50km and mixed road conditions (urban+rural), the performance degradation rate is ≤ 10% (after 5 years of use), meeting the long-term heavy duty engine bottom protection requirements.
Here are specific application scenarios of Left engine bottom guard plate:
Suitable for urban commuting cars, it can block the impact of road debris and gravel on the left oil pan of the engine. During daily driving, it can reduce 90% of shell scratches caused by small stone splashes, protect sensor wiring harnesses, and is particularly suitable for urban vehicles on multiple construction roads.
For SUVs driving on dirt roads in rural areas and gravel roads in mountainous areas, its high-strength material can resist the scratching of protruding stones and tree roots, avoiding the left side hose and oil pipe of the engine from being scratched, ensuring the safety of vehicle passage on unpaved roads.
In rainy or muddy areas, it can effectively prevent mud and water from directly washing away the left side components of the engine, reduce poor heat dissipation caused by sediment adhesion, and lower the risk of metal component corrosion. It is particularly suitable for vehicles in the southern rainy season or those who frequently travel on muddy roads in rural areas.
Suitable for off-road pickup trucks, it can withstand greater impact force during heavy load or off-road, protecting the left area of the engine from obstacle impact. At the same time, the drainage groove design quickly removes mud, maintains chassis cleanliness, and extends the life of engine accessories.
For vehicles with long vehicle age and aging chassis protection components, replacing the protective plate can restore the chassis protection ability, avoid engine component exposure caused by damage to the original protective plate, and improve the driving safety of old vehicles at low cost.
Confirm that the protective plate model matches the vehicle, prepare 10-14mm wrenches and torque wrenches, lift the vehicle (at least 30cm above the ground) or support it with a jack, clean the dust and soil on the left side of the chassis installation position, and check whether the original vehicle installation holes are intact.
Align the protective plate with the installation hole on the left side of the engine, manually insert the standard bolts for pre fixation, ensure that the protective plate is not offset (in contact with the chassis), and avoid blocking the heat dissipation holes or pipelines.
Use a torque wrench to tighten the bolts to a standard torque of 15-25N · m, and tighten diagonally in sequence to prevent uneven force distribution; After installation, shake the protective plate without looseness, check if the heat dissipation holes and drainage channels are unobstructed, and if there is no component interference, it is completed.
