Timing Belt Replacement Service

How much does a timing belt replacement cost?

Switching a timing belt for preventive reasons usually costs $500 to $900. However, replacing a broken timing belt may cost up to $2,000 or more if it produced damage to the valves, pistons or water pump.

What's a timing belt?

An engine timing belt is a fiber reinforced; toothed drive belt manufactured using heavy-duty compounds such as highly saturated nitrile. The timing belt lets the crankshaft to drive the camshafts in the cylinder head at half the RPMs of the crankshaft. The camshafts then open and close the engine’s intake and exhaust valves in time with the movement and position of the pistons in the engine.

Sings of a Bad or Failing Timing Belt

  • Ticking noise coming from the engine. The timing belt is connected by way of a series of pulleys to the engine's crank and camshaft.
  • Engine misfires.
  • Engine won't turn over. The engine will not be able to turn over or ignite if the timing belt has broken inside.
  • Oil leaking from in front of the motor

When should you replace your car's timing belt?

  • The old rule was every 100,000 km. As technology has progressed, many manufacturers recommend intervals up to 160,000 km. You should examine what the vehicle's manufacturer suggests and stay within that range to be safe.
  • Engine stops shortly or will not start. Occasionally, timing belts can skip, or break, while the engine is running.
  • Rough engine operation. The molded, reinforced teeth on the timing belt engage gears on the crankshaft and camshafts. The teeth can wear or break or the belt can stretch after many tens of thousands of miles, causing the belt to jump position on the crankshaft or camshaft gears as a result. If the belt jump, the engine will run inefficiently and sometimes not at all.
  • Banging or clanking engine noise. On some engines, the pistons and valves can collide and there will be noise and damage if the timing belt has jumped. These engine designs are referred to as interference engines. If your car has an interference engine, switching the timing belt according to the maintenance schedule will reduce the chance that a belt failure will cause engine damage.

How it's done

Engine designs vary so the replacement procedure will also vary, but broadly, the procedure is as follows:

  • Detach the battery ground cable.
  • Once the engine cools, set the crankshaft to top dead center with the number one piston on the compression stroke. Take out crankshaft pulley.
  • Remove all accessories interfering with the removal of the timing belt covers.
  • Take out timing belt covers. Lock camshafts, as needed, and note position of camshaft timing marks. Remove timing belt tensioner and idler pulleys. Take out timing belt.
  • Do so at this time if you’re planning on replacing the water pump, but first, drain the cooling system. If the engine cooling system thermostat is only accessible with water pump replacement, the thermostat should be replaced as well.
  • Installation of the new timing belt includes all of the above steps, performed in reverse, following strict guidelines to guarantee camshaft and crankshaft (and balancing shaft, if equipped) are in perfect alignment after tensioner has been set.
  • The engine crankshaft is turned by hand 720 degrees and the correct position of the timing marks on the crankshaft and the camshafts is ensured upon completion of the installation.
  • The vehicle is road tested to check normal operation and a service sticker is affixed to the engine noting the date of belt replacement and the vehicle mileage.

Is it safe to drive with a timing belt problem?

No, if a worn out timing belt to snap while underway, maybe on a highway, it poses risk of complete loss of engine power while surrounded by fast moving vehicles. You can remove the risk of unexpected and sudden timing belt breakage by having it replaced once your vehicle has reached the suggested replacement mileage for the belt. If your engine is of the interference type, it is particularly important to change the belt according to the maintenance schedule since sudden breakage of the timing belt, while the engine is running, will likely cause substantial damage to internal engine components such as the valves and pistons.

They changed a fan belt in my parkade downtown, came on time, and gave a quote prior to doing the work. Will use them again.

My wife’s car would start but stall at traffic lights. My best guess after checking battery and belts was that I’d require a new alternator. For the cost of a tow, the instamek mechanic diagnosed problem and got the car running. The technician Jack found a faulty sensor, cleaned the contacts and my wife is now happy once more. Very courteous and thorough service. No doubt I’ll be using them in the future.read more

Second time with InstaMek. After my alternator belt snapped, I contacted InstaMek, and with in an hour Alex was at my place with all the necessary parts. In the next hour my car was fixed and ready to go. I was impressed with communication, quick and convenient service. Good people, great service, very highly recommended.Alex was on time and inspected the car. Gave me great advice on possible fixes. The communication with the company is outstanding. It's both emails and text, and in this digital world it is very welcoming. I knew exactly when the mechanic would arrive and if there were any issues when arriving late. Absolutely outstanding and convenient service. I'm will definitely call on them again.read more

The service and convenience are HEAVEN!!!My wife dripped off our kids at the arena for a hickey game. As she was parking, there were funny jerks. Thankfully she was able to park. But the car was not starting. She took the kids to the hockey game. While watching the game, she called instamek and left he keys at the information desk for the mechanic. 4 hours later after the warm up, the game, and dressing the kids, my wife and the kdis walked to the parking to the now fully functioning vehicle. Here is a list of what they did (skme of the work was elevtive as i had asked for it)1) diagnostics2) new sparks plus3) new engine starter4) changed engine oil5) 4 break pads and rotars6) my passenger head lamp (broken from before)7) new battery8) new beltMy wife didnt even meet the mechanic.

After having a couple bad experiences at some large shops in Calgary I came across these guys while searching for another mechanic on google. Sounded a bit too good to be true at first, but after contacting them I was emailed back a detailed quote within 30 minutes. One day later I had a friendly mechanic named Clay show up at my work to replace my timing belt, water pump AND serpentine belt; all done in the parking lot well before I needed to drive home. This is an amazing service and I hope you guys get the recognition you deserve! Thanks!read more
