How Long Does It Take To Change A Starter
When I was an apprentice mechanic, replacing starter motors was a regular repair. In those days, accessing the starter was easy. Modern cars are not as generous but the starter motors are more durable. Here'southward where I share my starter motor replacement hacks.
Replacing a car's starter motor isn't hard. Withal, vehicles with large engines will exist more challenging. The front-cycle-drive transverse powertrain layout is the most common blazon and generally offers amend access to the starter motor, and is, therefore, easiest to replace.
In this mail, you'll learn how difficult it is to supplant a starter motor on both front-wheel bulldoze and rear-drive cars. I'll outline the workflow, yous'll learn about the tools y'all'll need and how long the whole job should take.
Starter Motor Replacement Challenges
Every automobile model will present item challenges but generally, we can grade the size of the challenge past ii criteria:
- How the engine is laid out in the engine bay
- How large the engine is
The first criteria – Powertrain layout (engine, manual, and bulldoze combined). The layout comes in two flavors – Longitudinal and Transverse.
The longitudinal layout means the engine is fitted in the engine bay, well…lengthways or front end to back if y'all like. It's mostly associated with rear-wheel drive and 4X4 vehicles.
The transverse layout means the engine is fitted in the engine bay width ways or left to right. It's mostly associated with forepart-wheel drive or all-bike bulldoze vehicles.
The starter motor replacement process differs for both, and we'll look at that procedure beneath.
The second benchmark is engine size. The concept is simple, the larger the engine the more than difficult the starter replacement process is.
It'southward not unusual on larger engines to remove several other components in gild to access and remove the starter motor. Some of the removed components may themselves require replacement gaskets, seals or recalibration, etc. These extra steps obviously add extra complication, price, fourth dimension, and endeavor.
Now let's have a look at the tools you'll need and then the process itself.
Tools To Replace Starter Motor
"Information technology depends" is a useless answer to any question, and I try difficult not to use it. But here information technology may be appropriate. The tools y'all need do depend on the challenge of the job at paw. If you lot are working on a family-sized motor you lot'll take no problem with regular tools.
However, if your wheels are powered past a larger donkey, yous'll need a few pro tools. I'll list them all hither, together with a clarification if applicable and you can cheque most of them out on the Mechanics tools page.
- KAM tool – Keeps power supplied to the vehicles control modules
- Ratchet and sockets – Proficient pick of extensions and swivels are of import for bad-mannered fasteners
- Ratcheting wrenches – Ratcheting wrenches speed upwardly the process
- Long swivel head ratchet – Telescoping handle with swivel head means you lot tin apply force where yous need information technology
- Billow bar – Great when loosening larger bolts
- Long handled drivers – Great for reaching clips deep in the engine
- Pry bar – Great when maneuvering larger components
- Pick set – Used when opening wiring connectors with brittle release tabs
- Mirror – Used to encounter fasteners that are obscured from view
- Lite – I tin can't work without information technology
- Magnet – Grabbing those fasteners that make an run for information technology
- Bungees – Used when holding attached components out of the work area
- Pliers – Used when removing clips and clasps
- Clamp removal tool – Used when removing hose pipage clamps in impossible locations
- Jack – Used to access the underside of the vehicle
- Axle stands – Used to access the underside of the vehicle
- Creeper – Used to work under the vehicle
- Bear upon wrench – Used when removing larger components like frazzle unions or support
Your job may non crave all these tools but nearly are needed.
Use A KAM Tool Before Disconnecting Battery
No matter which engine'southward powertrain layout. You'll need to fit a KAM tool. It's easy to fit and will save you a ton of actress piece of work and possibly a trip to the dealer.
What is a KAM tool?
It is a simple tool that powers your automobile's control modules while the battery is disconnected. The trouble with disconnecting the battery is, it kills the power to the car's computers.
Modern control modules are sophisticated, they learn and adapt as you drive the vehicle. They likewise allow for clothing and tear on a car'southward components. Removing the bombardment without maintaining power to the control modules causes these leaned settings to be lost.
Your motorcar will demand to learn these over. For well-nigh cars this isn't a huge issue, driving the car a few miles will help information technology learn the optimal settings but some cars may feel more than persistent bug with HVAC, engine idling, transmission gear changes, etc.
When these symptoms persist a date with the master dealer or sophisticated bi-directional tool is required to calibrate the various systems.
I utilise an Autel bi-directional scan tool and you'll find a link to both the scan tool and the KAM tool on the Auto electrical repair tools page.
Fitting a Kam Tool:
The KAM tool equally y'all know supplies ability to the car's computers while the battery is disconnected. The tool patently needs to be fitted before removing the car's bombardment cable.
The tool is equipped with crocodile clips at one end and an OBD plug at the other. The tool offers ii possible means to ability it up, either connect to a battery using the provided crocodile clips or connect to a donor vehicle via a12 volt plug provided.
Using the vehicle's own battery is the more usual way. Get-go, connect the crocodile clips to the battery in the usual style. Red to red positive sign and blackness to negative ground
The cablevision is long enough to reach from the car'south bombardment to the OBD port located on the driver'south side under the dash panel. Plug in the OBD plug and check for the lite indicator, that's information technology.
Your car'due south learned settings are safe so long every bit the crocodile clips remain continued. If there is a danger of them becoming disconnected, go ahead and remove the bombardment from the car and set it to i side out of the work surface area. You lot'll find a practiced KAM tool on the Mechanics tool folio.
Replacing Starter On Front Bike Drive
The transverse forepart-cycle drive is equally y'all know commonly the easier model to work on unless of form, the engine is unusually large. The starter motors on transverse models are ordinarily located at the front of the engine. This is the ideal location for the starter equally you won't demand to work under the car, a real bonus unless you accept access to a hoist.
Sadly non all transverse starters alive hither, some alive at the back of the engine and that ordinarily involves climbing under the vehicle. And the story tin get worse, if the starter lives at the back of the engine and the engine is large, it'due south likely you'll demand to remove other components.
My advice – for more challenging-looking engines consult a workshop manual. You don't want to remove more components than is necessary.
Information technology's not unusual for more challenging setups to crave half shaft removal, exhaust, pipework, motor mount.
But let'southward look at what the more common straightforward starter motor replacement procedure on a transverse forepart-wheel drive vehicle might wait similar:
- Fit KAM tool
- Remove battery negative final
- Remove air box assembly (nearly vehicles)
- Remove wiring harness from rear of starter
- Remove starter bolts
- Maneuver starter backways from the manual
Replacing Starter On Rear Cycle Drive
Replacing the starter on a longitudinal rear-wheel-drive vehicle isn't necessarily more challenging than the transverse front-drive vehicles. In fact, in many cases, the rear-drive starter motor offers a ton more room to piece of work.
The trade-off is that you'll be working on your back under the car. As a lifelong mechanic that's washed it both means, working on your back is the least fun, or perhaps I'm just doing it all wrong.
On a hoist replacing a starter motor on a rear-drive car is easy, with lots of room to work with few to no other components to impede your progress. Of class, in that location are large motor exceptions.
I've worked on a VW Phaeton for example and when I referred to the workshop repair manual under "Starter motor replacement" it states in a dry out Germanic way – "Remoffe engine".
It's not uncommon to remove engine supports, motor mounts, exhausts, etc. in social club to make room to work or to gain enough infinite to free the starter. Starters are bulky bits of kit.
Now let's look at what the more common straightforward starter motor replacement procedure on a longitudinal rear-bike-drive vehicle might look like:
- Fit KAM tool
- Remove bombardment negative last
- Jack vehicle
- Secure vehicle on beam stands
- Remove wiring harness from rear of starter
- Remove starter bolts
- Maneuver starter backways from the transmission
How Long Should Replacing A Starter Motor Have?
A straightforward starter removal should take more an hour and another hour to fit the replacement. A more challenging replacement process may accept 4 hours.
At the upper end, a whole twenty-four hour period or eight hours could be spent replacing a starter motor. That's assuming several other components also need to exist removed and you lot don't have the use of important time-saving tools like an touch wrench, hoist, etc.
My best communication, buy a digital repair manual for your auto and exist prepared for the task at paw. Empathise what components need to exist removed and in what order, you lot'll also know what tools or parts you'll need alee of time.
