my 300cd's "mods" - benzturbo - 05-01-2013

Hi everybody! I am new to std so i thought to start out i would share some of my little upgrades and such! Please feel free to ask ask questions! Smile

I installed an m117 fan and clutch. I believe the radiator is brass or copper.

There is way more room between the clutch and water pump so you can easily start those bolts and use the boxed end of your wrench!

Water pump pulley from an 85 300sd. With that fan, it sounds like a 747 taking off at lights!

This is a "dr44g" GM alternator that is rated at 130a but apparently wayyy underrated. Pulley offset is perfect but the upper bracket is currently hacked up because of the alts larger body.

bad pic but this is a w126 16inch aux fan to keep a/c cooler in traffic.

both the headlighs and fogs have been replaced with h4 E-Codes. My normal headlights have standard 55/60w hella halogens. The "fogs" now have 55w hi/lo HIDS. Perfectly safe to other drivers until i pull the knob out!

Awesome! Any more photos of the monster alternator?

RE: my 300cd's "mods" - benzturbo - 05-01-2013

No problem! Smile

the dr44g has its charge lug on the rear plus a 4 wire harness to its digital regulator. you only need to use one of them that goes to your factory charge lamp. The others are remote voltage sense, tach output, and some ecu input used on new gm vehicles.

4awg charge and direct ground to the alts body. the other wire from my battery goes to my amps in the trunk Smile

here you can see the ground...

this is the factory alt bracket that is all cut up. There is no tensioner. I am most likely just going to weld a washer on each side when i get new belts though i have not had any problems with this setup! Big Grin

with my original alternator and new voltage regulator, i went through 3 batteries with in 5 months. what killed them was idling. The voltage at idle with a/c on high, aux fan running, lights, stereo, ect would get low enough that my stereo would go into protect mode and my gauges would act up. I have not had any battery issues since and i have added even more electronics! after sitting over night, my battery is at 13.7! Big Grin I am very happy!

Could you expand on how those belts are staying tensioned with the alternator mounted like that. I may missing something, but that doesn't seem too secure.

I dig the temperature gauge idea

It's not the best setup. Big Grin someone has to be under the car with a prybar and push the alternator away from the engine to tension the belts while someone else tightens the bolt on the upper bracket. I have not had any issues yet with it loosing tension. it is just the normal bracket that has been cut about in half.

This is a terrible drawing in paint i did with the factory setup on the right and gm alt on the left with its larger body Big Grin

Thank you Smile It fits very well and looks like it is meant to be there!

I like the fan clutch idea!

The REAL test will be this summer here in Dallas, TX with a/c on high when its 110+ outside Cool Last summer i was having to turn my a/c off in traffic some days. If it can cool a 5.6L lwb mercedes, it better cool my diesel! Big Grin
