This tropically weathered Toyota Hilux LN85 (Year of Manufacture 1996) , Diesel Pickup Truck has a track record of 25+ years of lifespan upto now being on Sri Lanka's roads with a high road worthiness due to being well maintained throughout the years. It passes the country's yearly Smoke Emission Test quite easily in the first attempt itself since the testing was started in Sri Lanka around 2011. It did around 3500 kM averagely per month prior to Covid-19 pandemic and has a Diesel fuel consumption of 10 kMPL or 23.5 MPG(US) or 28.2 MPG(UK) with Air conditioning. The 2446 cc Hilux-LN85 Engine is still fuel efficient with (10km/l) average running. The 777,000 kM odometer reading mark was passed some time back and vehicle maintenance history is stated below. Presently (2024 May) this Toyota Hilux has done over 487,000 miles or 784,000 kM with the unopened original engine. This could be one of the few Toyota Hilux 2WD pickups with highest mileage recorded. One can safely answer to the question how many miles can a Toyota Hilux do as, over 482,000 miles in the original engine since this Hilux has surpassed the magic figure of 777,000 kM or 482,000 miles already.

The 2L-II engine in Toyota Hilux is an upgrade of the 2L introduced simultaneously with the 3L engine in 1988 in the 5th generation Hilux. Although bore and stroke remain the same, multiple changes have been made in its design. The engine block was made more rigid through the use of finite element analysis and through adding reinforcement ribbing. The most significant change is the redesigned cylinder head, where the camshaft now lifts the valve directly via tappet instead of using a rocker arm. The exhaust valve is 1mm larger in diameter and the inlet manifold is made 10mm larger in diameter. The pistons with a 5mm shorter compression height and piston rings were placed closer to the combustion chamber to reduce wasted volumetric capacity while durability was improved by the adoption of fiber reinforced piston grooves from the 1st Generation 2LTE to improve piston ring seizure resistance, groove wear resistance, thermal conductivity and thermal fatigue resistance over the previous Ni-Resist cast iron insert used previously to address ring seizure issues and wear resistance in bare aluminum pistons while the oil squirters were relocated to spray underneath the hottest part of the piston to further aid cooling. The revised pistons were 100g lighter than the ones in the 1st Generation 2L and the compression ratio changed to 22.2. The valve clearance is adjusted using shims. Later L engines (3L and 5L) also use this method of valve operation.

Maintenance Schedule adhered for the Hilux PickUp over the past years.

Vehicle Service schedule of Hilux LN86 Pickup

This being done at every 3500-4000 kM averaging 6 weeks between two services. The engine oil get changed (6 Lts of Lanka Super DS SAE 40 ) and Oil Filter change is done with VIC brand FC-158. Here all grease nipple points at under carriage is filled with grease. Checking of Gear Box oil level and Rear Differential oil level is also done. Removing of all Tyres including the Spare wheel is done and brake drums at rear is removed and brake pad mechanism is cleaned with hi pressured air stream. Hi pressure water is used to wash the under carriage and then a thin oil film is sprayed over it. Engine under the bonnet is cleaned with a low powered water spray as there are no Electronic parts in this truck! Then removing the water droplets by hi pressured air stream does the job. The Air filter is removed and with hi pressure air, the cleaning gets done. Normally an air filter lasts for about an year for this cab. Transmission Fluid gets topped up with Caltex Texamatic 1888 Red color fluid. Battery water level also is checked in all cells and filled with distilled water if necessary. The two oil spray points in the chassis is done with same treatment happening for the Door inside cavity where the windows rests. Washing outside and interior is finally done with the Truck coming out revitalized after each service. The best part of the story of the service is that the vehicle was serviced at the same service station without taking to another place throughout the years and the same mechanic is still there who did it for the very first owner.

Routine Maintenance of other Parts- Hilux LN86 Pickup

Engine Timing Belt replacement

Always gets the Original Toyota Timing belt and quality Japanese origin Pulley and Bearing kit for the Timing Belt replacement. Gets changed in every 85000 kM as the vehicle is in idle running 10% of the running time in various high traffic conditions. (Norm is 100,000 kM between Timing belt change). All other Belts in the engine gets replaced with this service.The Image below gives detailed Timing Belt Replacement Info with Timing Belt stickers that were used.

.

Diesel Injector Pump

The Diesel Injector pump had been serviced 3 times with replacement of the Nozzles with Zexel brand and replacement of O rings etc. Fantastic performance of the Fuel Pump. Fine pick up power without smoke. Very smooth engine - running like a car.

Power Steering Unit

Replaced the Power Steering pump recently with a reconditioned same brand and no other issues in the unit.

Battery Voltage Regulator

The original relay type unit was replaced with a Toyota HiAce Electronic Voltage Regulator 5 years back since the non original relay type voltage regulators were troublesome- either under charging or over charging. This new electronic unit is very reliable and high performing - keeping the battery in topping condition.

Battery

The Exide 95 AH Battery is a unique one with 2 year guruntee and here you really need the attention if you want to have the battery to last long. Due to the heat in the engine area the battery water gets evaporated rapidly if you do long stretches of driving regularly. If the Battery is used without the proper acid level, it gets damaged beyond repair. In this vehicle, the battery gets serviced monthly by the manufacture's service outlet for free (within the guarantee period). They check fluid density, level and voltage regulator's performance. Last battery performed well for 18 months and then a battery cell got bad. Got a free new replacement battery and it is reaching the end of 2nd year of high performance also! Needs to heat up the engine for 8 seconds and and in one shot the engine fires up.

Clutch

Aisin Torquemaster is the favourite here for replacement and for over 200,000 kM it worked without a problem. This time had to settle for a Exedy complete unit since the Torquemaster was not available. But Exedy it is not bad either. Cannot feel much difference but need to see how long it performs. Clutch replacement was not easy for the mechanics in this Hilux LN85 model. Had to struggle much with gear box de-and re attachment.

Engine & Gear Box

Original and untouched. But the Valve cover gascut had to be replaced and cover needed to re-face due to engine running with low water with Radiator leak 5 years back. Total negligence since not taking proper action even when noticing the Heat indicator near RED area! Stop driving and repair the fault before attempting to run with High Temp on the indicator.

Back Transmission and Propeller Shaft

The Propeller shaft was replaced with a reconditioned original about a year back. The differential unit is untouched and and not giving even a slight vibration even when running at 100kMpH in the Highway. But the cruising norm is 80kMpH for this vehicle.

Tyres

The original rimset was replaced with an Alloy Wheel set for 195 x 14 size Tyres. GT Radial Maxmiler was used many occasions and touching 60,000 kM of run at last time. Very recently settled for complete set of 4 tyres of Ovation brand. The ride is much smoother than the Maxmiler but need to watch for the durability. Filled with N2 to 45 PSIG but still goes smoothly.

Air Conditioner

Originally this truck model did not have AC but it had been modified to accommodate an AC compressor and a condenser next to the radiator facing the Grill of vehicle front. 2 Years back replaced the compressor with a Toyota HiAce model AC unit. Not high performance but it does the job.
