Thinking about oil cooler used on w124 with OM602A and manual tranny ( pic attatched) its smaller than G oil cooler used on 300GD, 290GD , etc.... The G one position is near radiator , not into fender so it receives much more air. G cooler plus 3 core radiator and OM606 water pump with small pulley will be ok , even on hot climates or not?

I think you will be ok with that combination Fernando. It is what i have with a 617a and it works well, even with A/C, and hot climate.

It is when you put an auto transmission with the 602a that you have a problem, but you can solve it by fitting a seperate transmission cooler into eg the fender or the sump protection plate, or you can drive softer.

My 290 GDT with auto transmission has completed 350 000 trouble free km without seperate transmission cooler, but the temperature guage is always around 100 C. When it goes higher I drive softer.

Just make sure that you "seal" the front end so that all air is forced through the radiator. Even the rubber seal that fits on front edge of the sump protection plate makes a small difference.

I think you will enjoy this engine. It is very reliable, good performance and 10 - 12 l/100 km.

Truck now is ready to go to AC shop( last hose must be made in place) and exhaust shop so we will decide what to do - go original way or go to the driver side after muffler ( my option).

About alternators I used 190D original A 007 154 54 02 ( AL65X) - 70A , the expensive A 010 154 08 02/4802 (Al0164X) used on 290GDT and OM662 fits the support too and its 90A. Support is A 603 150 04 70 ( think the same on 602 and 606).

Shifting rods had to be increased a little. I am using 711 117 with wolf shifting mechanism.

With AC poly belt must be A 008 997 36 92. Perfect.

Video of engine running into truck with no muffler, this engine doesnt need muffler !

Just to be 100%, can this part be orderded seperately? I didn't think so, but maybe you have more info on it.

Thanks,

Bram it cant be bought separetely. Guido found an old firewall and i bought it to cut the cone.The firewall without the cone can be used in many other projects , even rusted. Anyway the cone is only a base to acceleration cable and also protects a hole at the firewall, so it can be made if you have dimensions. You can buy the rubber buffer at epc .

Hi Fernando

Looking at your picture of the radiator, it appears you are missing two rather important clips to secure fan shroud to the radiator at the top.

I learned a hard lesson on my recent Morocco tour, about the effect of these clips.

In 2010 I replaced my old original G radiator with a Behr OEM unit. My original G radiator had two metal plates to fix a clip that holds the plastic fan shroud to the top of the radiator.

The Behr unit did not have those two plates, only the one holder in the center where you rest the shroud before putting in the screws at the four corners. So I just put the clips in a bag and forgot about them for 7 years.

In 7 years there was just a little tension on the center holder and the effect of the vibrations eventually managed to break it free of it's sautering. Had the clips been there, the fan shroud would have layed flat and no vibration or tension would have been transfered to the center holder.
Since the center holder is inside the shroud, the holder dropped, got caught by the fan and tore open 5 waterchannels in the radiator. Bugger...

Roadside emergency repair with epoxy glue, with credit to Andrew / Boy G as he once posted about such a repair in South Africa.
As I had to do the repair twice to locate all the holes, it took 8 hours of uncomfortable work.

Here is the offending holder that breaks free.

It caught the fan

Here is where the clip is supposed to be and of course also at the left side

If by any chance your radiator is missing those metal plates, it is just two rectangular brass plates that can be sautered on where the top of the radiator is corugated for strength.

After a while, I have learned my lesson well that the cheapest parts to buy, is only Mercedes original parts. Had way too many bad experiences with supposed OEM supliers.
