Timing Belt 2003 Volkswagon Passat V6 30V

Hi,
Actually the timing chain is for a lifetime, the only thing you replace is the chain guide and the tensioner.

Hope that helps you out!

The serpentine belt routing diagram for 2003 VW Passat V5 2.3 liter


CS = Crankshaft
F = Fan pulley
Gen = Alternator
G = Guide pulley
T = Tensioner pulley
AC = Air Conditioning
PAS = Power Assisted Steering

Hopefully you mean a sepentine belt and not the timing belt. There is a diagram under the hood for the serpentine belt. Look on the radiator shroud or close to it. The timing belt requires a great deal of engine disassembly and probably is more that most home mechanics can handle.

Only way to check yours LT 55 timing belts is to open the engine cover inside the cab,remove timing belt covers-because they are two-one is on a front of the engine another is for injector pump at the back of the engine.Just take a look at the timing belts.There is manufacturer mark.They must be brand new.If it is necessary just turn the engine even you can start.

Was looking at parts online and could not find a timing belt for the Jag. Did find the timing cover oil seal which makes me think it has a chain , not a belt so no worries. As always I could be wrong. The audi definitely has a belt , should be changed at 60,000 Miles / 100,000 Km. I have a passat with the 2.8 V6 and find performance is not great , nor is fuel economy.
The good and bad......... jag is newer , audi is lower mileage Both are slightly finicky and repair and maint would be more $$$ than more generic cars. Ignore carfax , it is an unreliable scam.
Take each to a mechanic of your choice for an inspection.
My personal opinion is it comes down to age. If you are over 45 go with the Jag , under 45 go with the audi. (lots of performance and apearance mods avail.)

Timing Component Alignment Marks: Locations
Caution: Incorrect removal or installation of the timing belt can result in damage to internal engine components.
- Turn crankshaft to cyl. 1 TDC (arrow) (Engine with manual transmission shown).
- Turn crankshaft to cyl. 1 TDC (arrow) (Engine with automatic transmission shown).
For complete Timing Belt Removal and Installation information: See: Timing Belt/Service and Repair

Volkswagen recommend a visual check(for this model) at the first 60,000 miles and then every 20,000 (replace if necessary). There is no manufacturer's recommended replacement interval. (Information gained from Autodata).
However most manufacturer's for the majority of models recommend a change at 72,000 or 5 years whichever comes first.
It is now known that a visual check is not reliable because the kevlar strands inside the belt break down over time and an indication of expected breakage is impossible to gauge.
Using the '72,000 or 5 year' advise, a belt change for anything older than a 2004 vehicle would be a good idea.
In money terms, a change of belt will cost 5 to 15% the cost of belt failure.

RDA servicing

i can walk u through doing a t belt. But if u are not sure if u are able to do it DO NOT DO IT cause if u are wrong if cause a lot of engine damage.

you need to remove front bumper , remove front into service position , remove aux belts set timing marks up ( you will need to use locking tools ) lock crank and cam shaft remove belt replace belt and tensioners . please note it is also use full to check water pump

Your engine uses a belt, the shop most likely wants to use a timing belt kit, you should replace the cam belt driven water pump as well

This is the timing belt kit
ACDELCO Part # TCK297P {6 Components (1 Belt, 1 Tensioner, 1 Idler, 3 Seals) #19164609}
BELT KIT,TMG INTERFERENCE ENGINE APPLICATION; DOES NOT INCLUDE CAM. TENSIONER HYD. ASSY.; TIMING BELT COMPONENT KIT W/SEAL PRICE $167.79

This is the water pump
CARDONE SELECT Part # 5583414 PRICE $70.99

So about $150 for parts, labor should be around 3-4 hours, here is California the job would price out for around $600.00

The parts are from the lowest price I found on the internet, this is WWW.Rockauto.com
