Water Pump seeping

[Jeff_oddo]

So my car is at the shop getting my OPG's and other stuff installed. They noticed that my water pump with 10K miles on it was showing signs it's seeping. I have posted a pic of it. What is causing the coolant to sort of gel up at the weep hole? They are installing a new one.

Have you ever added any additives to your coolant?

Added Water Wetter after I installed my 170* temp stat

Um, nobody mixed coolant types in your car I hope....

It is very possible that the water wetter was causing an excessive buildup of gel at the seals, which was then seeping out of the lower weep hole.

Here is a good article about water pump failures and causes.

I think at one point I might have poured some coolant in when it was low and I think it was Dexcool.... Oops

 

[Jeff_oddo]

Either way the coolant was drained out and pump was replaced.

I would have to verify, but I'm pretty sure DEXCOOL is compatible. Also, I would recommend a coolant flush to make sure there is not any more of that sludge/gel anywhere else.

Here is the one I used

Another shot on the back talks about its compatible

 

[JAS550]

It is compatible. The Motorcraft orange is pretty much the same thing as DEX-COOL.

 

[Jeff_oddo]

Yeah so I'm thinking maybe the water wetter might have been the culprit

Dexcool is known for gelling up. I prefer to use evans waterless coolant. Trumps water wetter and every other coolant ive used.

Nobody wanted to believe me but....Water Wetter is not a good idea. You are not the first person to use water wetter and have this happen.

I did some research on it last night after seeing the OP's problems. It looks to me that if you were running just straight water for coolant, then this stuff works well. Especially for its lubricating properties. But with any kind coolant mix, it causes some issues.

This is what I found about it last night:
