Does anyone have a part number for the main water pump for the C32?

I've found this on ebay and was about to purchase:

http://www.ebay.com.au/itm/WP6236-FA...ada2#vi-ilComp

Part #s:

MERCEDES-BENZ 1122000123
MERCEDES-BENZ 1122000401

C230 Mulac

According to RM European 112-200-13-01-88

When in doubt, use their website if you're looking for OEM part #'s. They have most of what you will need, and their prices are actually pretty good. I get most of my parts from them.

Unfortunate for you C32 guys with the $250 pump, our C55 pump is $85

Thanks mate... Yeah that price sucks ****! Anyone know of after market options. Found this on ebay

Personally, I stick to OEM parts...check www.autohausaz.com and www.pelicanparts.com and www.bmwmercedesparts.com and see who has the best price.

The one you found is showing the right interchange part # so it's correct, I just don't know how reliable the aftermarket ones are. You will probably be okay, I'm just picky about using OEM.

Thank you for the mention C230 Mulac, much appreciated.

Thanks mate ended up going with the cardone pump off eBay for ~$140.

My biggest problem isn't just finding the right part at the right price, I also have to deal with high shipping costs to Australia. Some stores have reasonable prices but then either don't ship internationally or the shipping costs blow out the price.

I did check a few of those stores and in most cases the pump delivered to Australia was going to cost close to $400. I'll take my chances with the aftermarket option with $30 shipping cost.

How much did the dealer charge for a new pump?

crembz

$750!!!!!!!!! Lol what a joke!

Design4111

Thats alot!! I bought one to keep on the shelf for a rainy day and I paid $300 at the dealer (for 55).

I know someone did an overhaul on their pump. I think he got the bearing and seal (around shaft) from the dealer and did it himself.

crembz

Yeah that's the price you pay in Australia... We call it the Australia tax... Everything is 2-3 times more expensive than the US. I suppose you could do that if you have the skill and tools. Unfortunately I have neither lol. Asking my Indy to do that would cost more than just buying one.

Either way I have a behr going in shortly so I'll just get them both done at the same time.

Waaw, that's horrible..

does anyone know what's the OEM brand;

Koolman/Graf/Laso/GMB..?

ZAYED,,

C230 Mulac

That's an excellent question, I was wondering the same thing...Graf and Saleri are the two on RME for the C55, but neither state OEM (which RME does a good job of noting on their website)

+1,

also, what's the Exactly difference between M112/M112K/M113/M113K water pumps..?

ZAYED,,

C230 Mulac

I don't know for sure but from looking at the parts online:

M112 - part #112-200-15-01 - says this in text: "This Pump does NOT have an additional outlet for engine oil cooler and can only be installed on vehicles that do not have an oil cooler mounted next to the oil filter housing. (2 Outlets)."

M113 - part #112-200-14-01 - says this in text: "This Pump has an additional outlet and is only for use on vehicles equipped with engine oil cooler mounted next to the oil filter housing. (3 Outlets)."

M112k - part #112-200-13-01-88 - this one is a lot more expensive and probably has to do with the additional cooling required by supercharger

M113k - part #113-200-01-01-88 - more expensive as well, same reason as M112k

Just using my intuition but that's just my best guess! I think this clears up the M112/M113 difference.

C230 Mulac

Also, that's from looking up a 2004 C320 (M112), 2005 C55 (M113), 2003 C32 (M112K), 2005 E55 (M113K)

Good input Petar..,

M112 & M113 sharing the same water pump,

SLK55 is the only M113 that has a different pump, cause it has separate additional oil cooler, same theory with all M113K's,,

but NOT sure why SLK55 has different part # than all M112/M112K/M113/M113K..!!

ZAYED,,

C230 Mulac

SLK55 is different? That's strange...maybe they made a smaller one to fit in there since it's a smaller car

cm60k

SLK55 pump # refers to Aluwag/GK brand, cause they are the only company which produce water pumps for M113K's, that's been from 2004 to 2010,

but not that sure if they still contracting with MB..!?!

i don't think there are any difference between SLK55 pump & M113K pump, i will try to be lucky & get SLK55 pump to see about that..!!

also, SLK55 has a different Thermostat #, with "AMG" written in it..!

Did we ever figure out if Graf or Saleri would be better or OEM? I'm about to replace my water pump and hoses as PM since I'm a bit over 100k now, but I'm not sure which I should buy. Graf is only $3 more so they're basically the same price (usually the OEM is one of the more expensive options with other parts).

I am going to pick up a pump from the dealer on Saturday ($230)., I will see if I can find any markings on it.

insame1

Went to the dealer.
Part number is 112-200-13-01-88 $235.17
Core Exchange $65.00

There was no manufacture markings on the pump. I did however find out that there no more new water pumps for our cars. All MB sells are re-manufactured units.

I heard dealer made a contract with "5" Remanufactured companies, (6) years ago,,

"2" company in Germany & "3" companies in China..!!

So I ended up ordering the Graf and installed it this Saturday. Man it's a PITA to do, mostly the draining of the radiator and having to squeeze the fan up and out. The fan has to be turned and angled JUST right to pull up out of there without unplugging the trans cooler lines (which I ended up having to do anyway and remove the radiator to re-tap the idler pulley hole don't ask why...but I'll explain anyway, sheared off idler pulley bolt a couple years ago and learned my lesson of using a torque wrench pretty quickly, drilled out the center of the pulley bolt head, tapped that with a larger bolt, tapped the hole in water pump and basically engineered a solution, it sucked).

The job took me about 4-5 hours I believe? Mostly because the pump has 18-20 bolts that hold it in, plus I also replaced all the radiator hoses while I was at it since I figured might as well get everything new on the system (only original items are the fan and aux pump at this point). For those of you who wish to do it, here are the torque specs from the STAR manual:

Smaller torx bolts that take the female socket - 14 Nm
Larger torx bolts that take the male socket - 20 Nm
Single alternator bolt at the top that also holds the water pump - 42 Nm
Hose clamps - 3 Nm (which basically means just screw them until they are snug and keeping a seal, don't overstress yourself)

Bolts on top of radiator and fan support are 10mm, undercar belly pan are 8mm. Always get new O rings for the radiator hoses and trans cooler lines that go into the radiator when you pull them out. If you buy new hoses they will come with O rings on them, but if you re-use the hoses, get the O rings. Tighten the water pump bolts in a criss-cross pattern the best you can, then torque in a similar fashion. Also make sure you use the new water pump gaskets provided and clean out the area before installing the new pump.

I think I've covered everything. If any of you are going to do this soon, feel free to ask me any questions.

Coolant Visit Workshop has not yet re-appeared...I am hoping it was the water pump that solved it!

Good write-up Petar..,

be careFUL; workshops will hates you..

ZAYED,,

C230 Mulac

haha thanks!

One other obvious thing to note, prob a good idea to park the car overnight and do it in the morning when it's cool. NEVER open the coolant reservoir when it's hot.
