Every three months or when the oil change is due, is the right time to perform a tune-up. A diesel engine needs good, clean oil, fuel, and air. Traditionally good car owners think that they are doing well by changing the oil when needed, take a look at the engine once a year, and let the state inspection guy tell them if they need something safety related. With this logic, the car seems fine and later on, down the road, the owner wonders what is wrong. I say this because some or most car owners don't perform a tune-up every year. Cars are lucky to see one in five years. A clogged fuel filter will increase fuel usage, wear out fuel injectors faster, cause more wear on the fuel injection pump and the fuel transfer pump, and cause O-rings to leak or fail. An over due oil change will affect the life and performance of the fuel injectors, fuel injection pump, engine cylinders and valves, and the turbo. An old, clogged air-filter will not allow the right amount of air to enter into the engine. This will cause carbon build-up (from unburned fuel). So now that I preached your ear off (lol). This is why I recommend performing a "Tune-up" at every oil change. I don't know how many miles you put on the vehicle each year and I don't know how much you want to do yourself. So I'll just put the information out there and you will need to decide if you want to do it or have someone else take care of it. Every time I perform an oil change I check the following (I work on a lot of different cars and trucks so some of the items may not be in your car): Oil level and color, last oil change interval, fuel filter, air filter, serpentine belt, related pulleys, damaged wiring or hoses, antifreeze lever, color, age, and the cap on the radiator and overflow tank, windshield washer level and performance, power steering fluid lever and color, brake fluid level and color, wiper blades, all lights, cracked lens, license plate and sticker, state inspection sticker, seat belts (need to function and be free of defects), Steering wheel is tight(no excessive play), horn works, All warning lights are working and none are are on while vehicle is running, climate controls work, wipers and washer fluid works, glass and mirrors are clean and not damaged, window glass, door handles and locks, exhaust (is it secured or leaking and are the heat-shields in place), gas cap, Tire wear, inflation, tread depth, even tread wear, no bubbles in side-walls of tread, no cuts, and the that all the valve stems have a valve cap in place, rims are free of defects (not bent, warped, cracked, or damaged), shocks, both front and rear suspension, brakes, E-brake operation, wheel bearings, steering components, transmission level, color, and condition, gear oil level, color, and condition inside the drive axle, rot, holes, and damage underneath, inspect E-VAP lines, fuel lines, brake lines, transmission lines, power steering lines, U-joints, yokes, seals, CV joints, grease components (like ball-joints and tie-rods), and that your spare tire is secure, and full of air. That is about it. If this is done then future repairs will not be a surprise, components will last longer, and when you do need a repair it will cost you less because you caught it before it damaged something else. I hope this helps you and if you have any other questions, please feel free to ask. Good luck. Also I do believe in Diesel fuel treatments. The new diesel fuel does not lubricate injectors well. Look for additives that clean and lubricate the fuel system and boosts Cetane levels.

Need to tune up my truck what will i need to replace

Hi Jeffery, You forgot to say if it has a petrol or diesel engine. In the case of a petrol engine, replace the the oil filter, fuel filter and air filter, and the spark plugs. Other than these items there is little else to do, as the engine performance is entirely controlled by the management system. The only difference between diesel and petrol powered vehicles during service, is that with diesel there are no spark plugs. Remember in the case of a diesel to fill the fuel filter with clean fuel before fitting it to the housing. Doing so will help in expelling the air from the system and make start up easier. Also fill the oil filter with the same multi grade engine oil used in service, so that on start up the engine is lubricated more quickly. Regards John

Does a toyota hilux surf 1995 diesel have spark plugs and points as in the days of yore??

Diesel engines don't have spark plugs. They use compression and heat to fire the diesel. Most diesel engines have glow plugs which are designed to preheat the combustion chamber to help burn the diesel fuel when you start it up. Hope this helps.

Technical tuning specifications for a 1997 Toyota Conquest 1300

Don't know about the 97, but I have a 99 escort, 00 corolla, 00 camry and 98 Suburban (though thats diesel so a diffrent animal altogether)... prior to that an 86 and 88 vw quantum and golf respectively... once electronic ignition became standard, there wasn't much "tuning left to do". Change the spark plugs, wires, cap an rotor, pcv valve, air filter, and fuel filter and I think you did a "tune up". With platihnum plugs an such you don't change the plugs often (like once every 5 years or so... depends on the plug, look in your manual). Get the Bosch warranteed wires from a place with lifetime warranty... remember where you bought them..., anything less will fail...

O2 sensors and catalytic converters can be a horror show. Aftermarket replacement catalytic converters cost a few dollars (about 1/3 of dealer cost) but they contain about 1/5th of the metals needed for catalytic conversion, so they fail in about 1 to 2 years... if you plan to keep the vehicle longer, plunk the money down, of you like replacing the things, get the aftermarkets, again a leftime warranty would be a neat trick, O2 sensors - sometimes you can get away with a 35$ universal from the discount shop, I did nonthe vw's, I did not on the toyotas....
