Brown sludge in water reservoir

The radiator was supposedly flushed this past year now I am seeing a brown think sludge in the reservoir and some is now appearing on the radiator cap.
Can you tell me what could be causing this and what needs done to fix the problem

    Thanks Phil,

    That is what I suspected

    Saturn adds conditioning pellets to the cooling system which is a Ginger Root derivative as I understand it. It causes the light brown "peanut butter" sludge in an effort to keep the water pump lubricated. The sludge first appears on the radiator cap. The sludge can also be caused by a coolant called DexCool. WAtch your temperature for overheating and you can have your pressures checked to see if you have a gasket issue but it is more than likely the normal Saturn sludge we all see and freak out over at first glance:)

    Before you go to extremes consider this: Saturn adds a conditioner to the coolant made of Ginger Root and it creates the "peanut butter" sludge at the radiator cap. It is used to lubricate the water pump. There is also a coolant called DexCool that creates a similar sludge. Watch for overheating and if still concerned have your pressure checked. The "peanut butter" sludge is a Saturn thing.

I would guess that it's your head gasket, are you getting any creamy residue on the bottom of your oil cap too, may be worth having a compression test done on your engine first

My antifreeze keeps turning brown and full of sludge. Why is this happening?


most probably a failed/split transmission cooler in the radiator tank
If that is the case , the fix is a new radiator and a chemical flush of the radiator
get quotes from an accredited radiator shop after getting a proper diagnosis of the fault

Just got a 96 Corolla and over heated. Noticed brown water coming out from under it. And when opened the radiator cap. Found brown sludge in it. Don't knw what to do


Sounds and looks like the radiator is corroded internally. My guess is that it has been leaking for a while and re-filled with water only and no anti-freeze to help keep it clean. Pull the bottom hose off the radiator and try to flush it out with a hose and see what you get.

2005 grand cherokee larado running hot after at lease 30 miles already replaced thermastat, water pump


Could be a number of things. Since you replaced t-sta and pump. Check to see if the fans works(electric). Should be at low speed around 210 degrees, high speed at 225. If it is a clutch fan., on the water pump. there should be some resistance to it. It really shouldn't spin at all. two blades of movement is pushing it. If it has any slop(front to back) replace it. I would also check the radiator cap. pull it and see if there is any brown sludge on it , or down in the radiator. This tells me that some one has put stop leak in it..

There is brown sludge in radiator what is the cause do you think


The sludge is due to rust in the cooling system due to lack of maintinance, you will need to have the system flushed, you will need to remove the upper and lower hoses from the engine and run the water hose through the radiator first, you will need to do this a few times, then the next thing would be to remove the thermostant and run water throught the engine, the water will go in from the top, star the engine while water is flowing through the engine dont let engine run to long it will overheat, let it run for about 2 min at a time, then with the thermostat out install the housing and connect hoses, pour some cooling system cleaner into radiator and run engine for about 20 min, then flush out again, then refill and run again with water and then drain it out and fill with coolant, make sure that the coolant is mixed 50/50 coolant and water, you will notice that after it runs for a while it will turn brown again due to build up in radiator and engine, there is nothing you can do about that but atleast the coolant will be good and stop the internal gaskets and radiator from rusting out, you will what to do this again in 6 months to get it cleaner. good day. hope this helps.

1998 blazer blows warm air on heat, sometimes temp.gos up fast to red, had radiator flushed and flushed! looks like brown mud! and chunks think allot of stop leak was added only does this in winter it...


Sorry to hear about your cooling problem,
If it is as nasty in the radiator as you say,you will need to replace radiator.One option is to pull radiaitor and have a radiator shop clean out, but with it being a 98 the tanks will crack as they are plastic so I would recommend replacing. this was a problem on these older models with the dexcool they would get low in coolant and the air is system would turn it to sludge.

My buick is overheating and has brown sludge in the radiator. why?


most likely the intake gasket is shot. check to see if the gaket is leaking. if the gasket fails it will add oil to coolant. i did mine on a 3.1 last year, and it has been running good since then. if you do the job, do not to forget to flush out system good before adding new coolant. you can check for a head gasket leak, but this usually causes car to over heat etc. check intake gasket. if this is the 3.1 or bigger. they have a new revised intake gasket set. mine had a lot of oil in coolant tank!! good-luck!!
