Preventative Maintenace

Where do you run in Australia?

 

waterpump max 5 y.

Smart man to do work like this.
preventative maintenance is the best way.

 

Owners manual and manufacturers website are good sources of information you seek.

I have an N14 .
Belts and hoses I change all of them when one gets bad.

Alternator, starter a/c pump, air pressure pump. Change when they go bad. There are signs when these are getting weak.

Water pump will seep coolant thru the weep hole. Change ASAP.
Thermostat change when it goes bad.

Turbo. I changed mine at least 10 years old. I didn't want to wait for it to go bad.

Condenser, radiator oil cooler change when they fail.
My radiator was flaking metal internally, 3years old. I changed the radiator, hoses
oil cooler and the housing the oil cooler mounts on.

Injectors I change all 6 when 1 goes bad.
Air dryer every 2 years.
Oil pump when the mechanic tells me it's bad.

I see preventive maintenance as an investment.

Good luck.

 

I would not do any of the things just because.
What I would do however is if you have to make a cooling system repair THEN I would go through and replace hoses, radiator, water pump etc.

If you lose a brake can then replace the hoses while it’s off.

If it needs pads and drums evaluate the s cams and slack adjusters.

if the clutch goes out, put a new main seal in along with new linkage for the clutch, new rear main seal and maybe even have them pull the cover on the transmission? Maybe do u joints and carrier bearing while it’s down?

When something in the system brakes or gets to the point of repair look at the WHOLE system.

I wouldn’t just randomly replace a water pump. water pump could easily last as long as the engine.

Only preventive maintenance I would do would be oil changes and grease jobs and the occasional valve adjustments. Having stuff torn apart by a shop “ just because” is asking for serious trouble.

 

Grease the trucks every 2 weeks, and change the oil at the manufacturers recomended drain intervals. Don't fix things that are not broken.

 

I usually do a complete in frame at every overhead, replace the oil pump at every oil change and when I install new tires I replace all the wheel studs and nuts, wheel seals, bearings, and buy new wheels just in case. After exactly 50,000 brake applications the entire system gets replaced from compressor to the wheel ends for safety’s sake.
When one light goes out I replace all the lights and bulbs along with their switches to avoid future downtime.
To avoid any fuel system problems the fuel lines, hoses, fillters and pump gets replaced at every fill up and new fuel caps get installed for added assurance.
