Cooland changed color from blue to gold?

[Olivier]

Hi,
Just saw that my water pump is shot, there was some coolant at the front of the engine, odly it was a wee gold ish in color, once I openend the reservoir, the coolant was defenitly not the proper MB coolant color??? I have changed it when I got the car with the proper stuff.
It is now orange/ gold ish?
I just hope this is the water pump that as desintegrated and colored the coolant, or is there other thing I should be worry about?
Would an over heated coolant change color? To my knowledge the car never overheated and the electric pump is working fne, then the coolat shoult be circulating OK.
Cheers.
Olivier

Get your pump looked at ASAP. The last thing you want is a minor crack on your head gasket, it could be oil and coolant mixing.

 

[Olivier]

I know, I am looking for a replacement at the moment.

Cheers.

Its picked up rust along the way, probably when car has been standing for some time? it probably changed colour some time ago..

 

[Olivier]

Oh, that could be it? When I got the car there was no antifreeze, only water

 

[jaymanek]

Yep there you go, without antifreeze, rust forms quickly.

Every been bodyshop?

 

[Olivier]

Hi Auto-mobile, what do you mean by that
Cheers.

I guess he's asking if you've been to a car body shop recently?

 

[Olivier]

OK, but why?

 

[Auto-mobile]

Because they use crap coolant that's why, there is no other reason why mb blue coolant would change colour unless it's 10-15 years old etc, hen worked at Merc you could tell which cars had been bodyshop as they had fluorescent green or yellow coolant

 

[Olivier]

Cheers.
Nope, never went into a body shop.

At work we use Merc diesel engines and 1 of ours was the same, it was about 8 months old, untouched and the 3 it arrived with were all fine but this was about the colour of pee and stunk fishy. Changed and no problems.
Somebody mentioned oil, but in my experience it floats so the header tank would be full of mayo type gunk.

I thought modern coolants were supposed to change colour if combustion gasses leak in. perform a "block test" to be sure.

 

[Olivier]

How do you do a block test?
Cheers.
