How do you know when to replace this pump? Mechanic says to do it now (120K) because it could damage the climate control system in the dash.

Soccer,
Yes, the auxilliary water pump can indeed cause damage to the climate control, however, why replace it if it's not bad. Check the pump to see that it does NOT draw more than 1.3 Amps. If it draws more than 1.3 Amps, replace it. I personally think that replacing parts on one car at a particular mileage because the same part failed on other cars at that same mileage without testing them is wasteful. My auxilliary water pump on my '88 124 with 170K miles is still working fine. I checked it not too long ago for current draw and it was fine. If I had replaced it at 120K miles it would have been a waste of money and effort. I believe mine is still in good shape, because I have kept the cooling system flushed and clean. If your cooling system has gotten dirty and been ignored, your pump may not pass the test. But it doesn't cost anything to test it. Give it a shot.

The amperage test is the only way to do this.
Be sure to test and replace items only as needed. ------------------ Benzmac: Donnie Drummonds 1992 500E (very soon I hope 1981 280GE SWB ASE CERTIFIED MASTER AUTO TECHNICIAN SERVICE MANAGER FOR 14 BAY FACILITY MERCEDES SPECIALIST 8 YRS PARTNER IN MERCEDESSHOP.COM |

Doing some necroposting here, hoping to get some answers on these
W124 Secondary Water Pumps. I have a 1989 W124 300TE and the secondary pump is seeping/leaking water but it appears to be working correctly. Can these secondary pumps be rebuilt? Also, when I look up the secondary pump on various sites it shows two and I am not sure which one to get, does it even matter which one I get? what are the differences between the two? One is in the 80-90 dollar price range and the other is more like 130-150 price range. |

Heck yeah, If it is in good shape I am interested!!!! To anyone else checking this out, I would like to see any answers you have on my questions. It seems goofy that you can not fix one if it is leaky and I am interested in the "why" and "what's the difference" between the two they offer. |
