Special Tools for Audi S8 Timing Belt Replacement 4.2L 40V Models

BACK TO >> Audi S8 Timing Belt Information Table of Contents

Do I need special tools? Can I do it without the tools?

When replacing the Audi S8 timing belt on my 4.2L model, do I need the special tools? On older single-cam Audi engines it is possible to achieve general timing without the special tools. However, on modern (double overhead cam) interference Audi engines this is very risky. Special tools were designed for a reason. They maintain proper timing relationship between the camshafts and the crankshaft position. Slight variations in timing or orientation can result in catastrophic engine damage (e.g. bent valves).

This isn't the area of vehicle maintenance to cut corners or try to save time. For example, most new vehicles have tapered camshaft sprocket(s). On these Audi models, in order to achieve 100% proper cam to crankshaft timing, special tools are absolutely necessary. When the timing is off just a degree or two the check engine light could appear and a lack of performance is often noticed. Remember, you're performing a crucial maintenance repair. If done incorrectly, catastrophic engine damage will result.

Audi S8 Timing Belt Tool Rental Program

How Does Our Tool Rental Program Work? As a courtesy and for a small fee ($65.00), we offer the option of renting an Audi Timing Belt Tool Rental Kit to customers who purchase one of our BLAU Audi Timing Belt Replacement Kits.

Our Audi timing belt tool rental program allows technicians to use the special tools required, without the investment. For example, a set of special timing belt tools for a 4.2L engine can cost around $600 or more.

An Audi Timing Belt Tool Rental Kit can be in your possession for a total of 7 days. We add appropriate transit time to your 7 day rental. When you receive your package, your invoice and the tool kit itself will have the specified date that your tool rental kit is required back (received in our facility).

What is a tool deposit? A tool deposit is an amount of money put down at the time of tool rental to ensure the return of the tool kit and adherence to our rental policies, agreement, and procedures. This is a good faith tool deposit. The deposit amount varies depending on the actual replacement cost of tools. The refund of your deposit is given when the tool kit has been returned in complete and good condition. For more information see our Tool Rental Policy.

PLEASE NOTE: The small fee we charge doesn't even cover the costs associated with this tool rental program. We offer this as a courtesy to our customers, whom we view as friends. With this in mind, our Audi Timing Belt Tool Rental Kits are not available without the purchase of a BLAU Audi Timing Belt Replacement Kit. Purchasing a timing belt kit and tool rental kit from Blauparts with the intent of using the tools to install timing belt parts purchased elsewhere and then returning our timing belt kit is not allowed. Due to the complications of international laws, shipping variables, duties, taxes, and returns, tool rental kits are not available to rent outside of the contiguous 48 US states. Thank you for your understanding.
