Engine Timing Belt Change Interval
I am still working on a set of technical notes that relate to engine timing belts.
I have made a thorough check of the Owners Handbook, the Service Portfolio and the Brooklands edition of the Rover 75 and MG ZT Workshop Manual and have not found any written information about the intervals at which the engine timing belts should be changed. Originally I was informed by my Rover dealership here in Melbourne, Australia that the timing belts should be changed at 145,000 kilometres or after six years use, whichever event came first. I have not yet seen this important information written in a MG Rover produced document. To me, this omission is extremely strange. My selling dealer is now defunct, so I can't check there. Does anyone in our group know where this important information was written for owners to act upon? Having visited several Website forums on this subject, I have found out that Holden/Vauxhall Astra/Vectra intervals have been reduced significantly, as have those for Audi cars, in the interest of reducing warranty costs. Bung it back on the customer! Noted also, is the fact that the Rover KV6 and 25K4F engines enjoy the longest timing belt change interval of all. I believe this subject is/was important enough to warrant a copy of pertinent written notification -- somewhere. Thanks for help, again, Mike Allfrey. Rover Car Club of Australia Inc. |

My 2003 service schedule from Rover, and the Haynes workshop manual, quote six years or 90,000mls. It's a good idea to reduce this a bit bacause of the disasterous results from a broken belt, so why risk it.

Hi Mike and welcome....
After reading a few threads here I've got the impression that most are changed around the 90,000 - 100,000km. mark. I think this is mainly due to the fact that on average most people (in UK) do about 16,000km a year, so 6 years. I'm sure you can do the math...... Hope this helps.

And of course the R75 diesel has a chain drive which will last the life of the engine.

Here's the 2004 official MGR service listing. Cam belt replacement at the recommended 6 years/90K miles is the most cost effective schedule. The OEM belts have a notional ten year life, so MGR knew what they were doing in setting down the schedules. Of course, many people change stuff much earlier, which is their prerogative.

Diesel Camshaft
This 'throw away' remark has cheered me up no end! Having previously had a peugeot diesel where the belt had to be changed every 70k, I was getting twitchy about my R75 now recording 143k, even wondering if it had been done the first time (no mention in the servicing record). This now confirms that I don't need to worry about it and I was slightly puzzled by the fact that my copy of the Maintenance check sheet noted above states that the 90k replacement is for Petrol models only. Yippee, I can concentrate on other things now. Thanks Colvert and of course Mike in Aus who started the thread
