Just read the diy instructions on 95 400E.Seems really straight forward,no need to remove plug # 1 to align marks etc,TDC and what not.
Is it this simple on a older 92 300E 2.6.If that is so,its R & R time ,no need to procrastinate on this preventative maintenance.
Thanks

Hi Tom,

I just replaced my dist. cap and rotor a few weeks ago on my 1988 300E W124. Very straightforward. Pull off plug wires from the dist. cap (make sure you note down which plug wire goes to which socket on the cap (well, actually, it's printed on the dist. cap cover (the black cover that you have to remove from the old cap and put on the new cap)), then remove the 3 allen screws holding the cap down, pull off cap...then remove the smaller 3 allen screws holding the rotor down. That's it! The new rotor will only go in one correct way, so you can't go wrong! Then reassemble everything back together and that's it.

The only thing I'm not sure of is whether the negative terminal of the battery needs to be disconnected for this procedure. I disconnected it when I did my dist. cap and rotor. Can any one clarify this?

Hope this helps.

Im planning on doing the wires, dist cap and rotor myself also. It would be nice to have detailed step by step instructions. Looks pretty simple. By the way, Autozone carry's the Bosch wires for 99 bucks--what a deal!!

Hello,E Lee,fellow Torontonians,I replaced my plug wires 2 yrs ago with a set of Bosch,160C$ tax included but the supplier,former STP Volvo has gone out of bussiness.Where did you get your cap and rotor in T/O.Many thanks,

Save yer selves some Dollars.

Get a DVM ...Ohmeter.. and measure th resistance between the post in the distributor cap and measure the cap at the other end of that posts wire.
Set the Ohmeter to 20kohm
and copper leads with ends should read about 8-14kohms......somewhere in there ....be aware of the lead open or high ohms.

Tom, the 300E pretty much tunes itself. Replacing consumable ignition components and filters is about all you can add to the mix. The engine management system is really top notch. Have no idea what They would be doing for $500.00 of anyone's kind of money..
