RE: [diesel_mercedes] Water Pump?

 

Bearings and the ceramic seal are done.   New pump and thermostat and V belt.  Easier to do

with radiator out.

I'm loosing tons of coolant and it looks like it is from the water pump.  I don't hear any noise and I can wobble the fins on the fan.

 

Any way to tell if it really is the water pump or a leak from some other source?

 

TIA!

Usually you take a mirror and look underneath the water pump. There is a hole there; there will probably be a stain trail of rusty water. I have never seen anything else in this area cause a leak except a failing water pump. Any play in the shaft is a failing water pump.  Bill in Oregon

The water pump can leak w/o the noise and wobble. If it's not leaking from the water pump where could it be leaking from? Maybe the Thermostat housing, or that short hose from the head to the block behind the thermostat housing. Check those places too. Eliminate the other possible leaks, and you have a leaky water pump, especially if it's dripping off the bottom of the water pump.

Ah, I see. Interesting, thanks.

Re: [diesel_mercedes] STARTRON For Fungus

 

I'm a big fan of the Amsoil Diesel additive.  Keeps the tank and system clean and provides the much needed lubricant that our cars require and was removed from diesel fuel some years ago.  It's not anti-fungal, but, I was not given the crap-in-the-tank curse that Nate has ben ever plagued with.

I put Startron in once each year as preventive maintenance, and have never had any fungus issues. But many years ago when I first got "Mary" I did get clogged up with waxy parafin in the see through filter and had no idea why the car kept crapping out on the freeways. After that, I started the additive routine (DieselKleen, Startron) and fuel stations with good volume turn over. No fuel problems for 10-12 years.

The speedo and odo do run off the same gear, but, the speedo uses a magnetic coupling with a spring to return the needle to zero, and this spring can be strong or weak.  Or, the needle may not be set at the same point on the pivot in your car as it is on my car, so there may be differences in what my speedo says compared to yours, even when we're both going the same actual speed.  Keep in mind that speedo manufacturers often calibrated the guages to display faster than the actual speed, for liability and maybe safety sake.

The odo, on the other hand, is more directly connected to the gear in the transmission, though by a slip clutch.

I thought the speedo and the odo ran off the same gear, no? My 82 has a
drain plug low center below the manifolds. Fairly easy to get to. I
plumbed the coolant heater into it.
Handy for flushing having a hose attached there. I was able to flush it
out backwards, bottom -up, as it were.

I can only say that I learned many years ago to order and carry in my car replacement plastic drain plugs because sooner or later you will snap the head off one of those when tightening or untightening them from the bottom of your radiator. Like fuel filters, they are cheap and can be replaced quickly and easily anytime you feel the urge.
