DENSO Alternator - DAN938 - OE Number: 27060-0G011

on the toyota avensis t25 with a 2.2 litre 2ad-fhv turbo diesel engine, the battery intermittently was not charging and in its last week it became a liability; monitoring with a digital voltmeter inserted in the auxiliary power outlet, I could see it would stop charging 2 to 3 times per journey, and had to restart the engine to make it recharge again; the voltage regulator of the original alternator needed replacing; even after having done 140000+ miles with the original alternator, I could see that it was truly brand new still: the pulley and its clutch was immaculate, and the bearings had no play whatsoever and making no worrying noise; I could have replaced the voltage regulator, but the Denso DAN938 Alternator was only £105.29, and that in my opinion meant a guaranteed extra 140000 miles of trouble free travelling.a mechanic asked me £400 labour and parts for the replacement , and did not even know the toyota avensis had a 2ad-fhv engine; so knowing that the labour was going to be higher once he was going to get started, I decided to do it myself.the alternator on the 2ad-fhv is caged; to swap this alternator one has to take off all of the underbody plastic covers, the RH CV axle, lose some transmission oil in the process, replace the alternator, put the RH CV axle back in, do a full transmission oil change while at it, enjoyed.I have monitored the charging on every journey for a couple of weeks thereafter, and is totally reliable. I have a new OEM alternator now with a few hours of DIY and a Denso DAN938 for £105.29.
