Sr Brownish

[wangan_cruiser]

let me start with this. i replaced gaskets for thermostat housing and waterpump. then small amount of coolant gush out. but then i was wonderin why is there a mixture of cooland and brown residue? then i popped the sparkplugs and the threads is coated with brown powder on it. im thinking what it is right now but not so sure. anyone can tell me?


btw i have a sr

[boogerlovers]

the brown residue in the coolant could be rust/corrosion from your radiator is it the stock one...? as for the spark plugs maybe some one used a lube on the threads thinking that it would help against seazing, but the lube probably burned away. i know your supposed to use anti-seize on your spark plugs but there is a specific high temp one...hope i helped a little :hs:

I have worked professionally in autoparts/service centers for about 5 years. And worked on my own shit since i was 16. I have never heard of high heat anti sieze. On the brown coolant residue coming out of the water outlet in the block, and waterpump.. We had this happen to us a few times. The most common, was people putting the wrong coolant in their car when they had old shit in there. The two have a slight chemical reaction which distroys radiators, heater cores, waterpumps, t-stats, sometimes it can eat the H.G. too. Try flushing the system and see what that does for ya.

i didnt necessarily mean high temp anti seize, more along the lines of high temp lube...something that would burn up and turn into dust or crap, kind of like what he found on his spark plugs...way to nit-pick at my post, im just tryin to help dude out

Take the coolant/brown shit.

Put it in a clear glass of water about 1/3 full. Fill 1/2 with flat tap water. If the brown shit floats above the coolant then you have oil in your coolant, if the brown shit sinks, then it is just rust.

Yes you can thank me now. lol

haha i dont think i would have thought of that, as blatantly obvious a solution it is, to finding out what that brown crap is....

[wangan_cruiser]

btw the engine is not currently running coz im in the process replacing all the gaskets. and on top of that.....i know that there is no way of oil and water will mix. correct me if im wrong.

is it ok to flush the coolant with water from the block?

[drift Kid]

damn i have brown shit in my rad too..

[blu808]

wrong. You can have oil in your coolant, or coolant in your oil.

If you have a blown head gasket, or a cracked sleeve then you will have coolant in your oil, or oil in your coolant.

Has the car ever overheated?

[blu808]

Usually though brown shit is just corrosion from the radiator.

If you have ever owned an old american car with an iron block you know what im talking about.

Drain your coolant and like 10 lbs of rust will come out. lol

[wangan_cruiser]

heehe thats what im thinkin...does anyone knows that rust has a smell? LOL

[blu808]

no but if you stick a magnet in your radiator filler neck it will pick up some of the brown shit if it is actually rust.

Keep in mind that the sr is aluminum block and wont make brown rust. just white flaky corrosion.

[wangan_cruiser]

yea and you can easily tell if its oil or just corrosion. just makin sure

[blu808]

Is that a question? Or a really odd statement?

[wangan_cruiser]

question...forgot the ?

[blu808]

you can tell it is oil if the brown stuff floats and beads up like oil floating on water.

You can tell if its rust (metallic) if it sticks to a magnet.

[blu808]

or if it sinks, it is rust.

[wangan_cruiser]

i already closed the waterpump and the thermostat housing. im wonderin that if its cool to pour some water to the waterneck so i can wash it out.

[blu808]

Yea alot of people dont even run coolant. Track cars are not allowed to use antifreeze because its hard to clean up when it gets on the track.

Flush it with as much water as you would like. Keep in mind that antifreeze/coolant raises your boiling point as well.

ya but as most of us know there are little additives you CAN use at the track, that raise the boiling temp. You just dump in with water. They are like 9.99 at autozone.

Don't use anti-seize in aluminum heads. 1) aluminum is soft and is easy to strip, and 2) anti seize reduces the amount of torque you can put on the bolt (or spark plug in this case) before you strip something. There's a term for it we use at work... I can't remember it for the life of me though... damn 14 hour days.

I think its wet torque spec....

[blu808]

Water wetter made by redline is a popular additive.

LA_phantom_240: I would have to disagree. You should always use antiseize on any steel bolt that is threading into aluminum.

Water wetter!! thats the shit. I run that in my cars in summer. i have to switch it out in the late fall because it would freeze. But its worth it.

i agree with this. on a steel bolt threading into aluminum i just use very little antiseize. though i dont think it matters as long as you dont glob tons of the shit in there.

I have mixed feelings. I don't use it on spark plugs. I'd rather have a slightly tougher time taking them out than risk stripping em. I have a habit of stripping things in aluminum heads....

if you use just a touch of it.. i am talking barely anything. like the size of the tip of a pen and torque your plugs to factory specs.. I highly doubt you will ever strip one out. i use it all the time. lug nuts, caliper bracket bolts, inner tie rod ends, outer tie rod ends, etc.. I just use a little bit though. Have never once had a problem due to not using it.

Oh yeah, I almost always use it on brake and suspension parts. They suck ass without it lol.

[wangan_cruiser]

shit i forgot to mention that the motor is out of the engine bay...is it ok to pour water in it to wash off the old coolant?

[dxs080jpgex]

i did. when i was replacing the water pump i hooked up a hose to my rad and blasted water through it to get all the crap out. it came out brown water. i wouldnt advise on shooting a hose through your motor.... but idk
