Okay I decided to clean my engine bay out and check my fluids and what not. Come to find out when I looked into my coolant can and radiator I find this crap. I called a local shop and they told me to flush out my radiator and if it keeps on doing it. I might have to flush it out a few times for it to clear up. Any information you guys would really help me out. Motor is a Jdm b18c Gsr all stock.

 

Blown headgasket. Oil is getting into the coolant.

 

Looks like you have a little bit of rust there. I think theres some stuff you could get from autozone that cleans that out that type of crap. I think you run it for a day then drain out your cooling system by sticking the hose in the radiator and letting it run through.

Never used it myself but saw it once.

 

Well I took it to the shop a couple of days ago and they said my headgasket was fine.

 

Yeah that looks like rust.. Just probably hasn't been changed in a LONG time.

 

Really rust from where ever sense I had my car which was a few years I never did really have a coolant flush or anything more information on this would be great thanks in advance. And this swap was put in 2 months ago engine 96.

 

i dont know about u, but i had the same crap in my coolent can thing, and i just took it off and washed it. and thats it and its been like 2 years from then and i dont get that **** in there anymore, oh and i changed the coolent once last year, so ya just flush out the coolent and clean inside that can and u should be good to go.

 

change the coolant.. flush the system..

 

So if I get it flushed and his happens again should I keep getting it flush until it clears up?

 

Yeah, looks more like rust than an HG, but you never know. Follow my DIY on flushing your system...let me know if you have any questions. https://honda-tech.com/zerothread?id=1424191

 

I guarantee you that the previous coolant change(s) were with tap water. Once you clean your system out, make sure you only add purified water from the store (this means no brita filter ****).

 

I just did this. Mine had a TINY bit of this gunk, but it wasnt as rust colored. I drained the radiator, washed out the resevior tank, and sat with a hose for a few minutes spraying into the radiator. Looks to me like it cleaned it out quite a bit...

I have used tap water countless times on previous cars, and drove thousands and thousands of miles. Nothing like this happened. So I cant say wether or not this is the direct cause, but again we need to look at how long its been in the system.

Yeah, rust lol. You do realize that everything that the coolant touches inside the motor is aluminum?

 

are the sleeves aluminum, I think not

 

So should I just stop driving the car until I get my radiator flushed?

 

How soon can you do it?

 

flush it out, it's all rust deposits

 

just drain your radiator, fill it back up, run the car till it opens the thermostat and then drain and fill it again. you should be set
Oh yeah and wash out your overflow bottle

Think about what you just said... Think REAL hard, maybe it will come to you..

Anyways, flush that system out very well, get that cheap *** green coolant crap out of there. You NEED to run a non silicate based coolant like Honda/Toyota coolant.

 

im almost 100% sure that the reason u have all that gooey gunk is because u probably put straight antifreze in ther...u have to either dillute it or buy it pre mixed...so remember when u flush it out..dont fill it back up with undilluted antifreze...n u shud b fine

 

No no. You don't know what your talking about. Go take an ASE test and maybe you will learn why tap water is a big NO.

Can you use tap water? sure you can, just like you can put an engine together with no torque wrench.

Why is tap water not as good as pure water? tap water contains minerals which causes corrosion. this is why you see crusty white deposits around water necks. ever seen lime deposits in showers? same reason why.

tap water is very different citywide. tap water in nyc contains much more ppm (parts per million) of minerals than in places like alaska. whats worse is tap water starts at lower ppm and ends up higher at the faucet due to traveling through corrosive pipes. rust is different than corrosion. all metal is corrosive.

Basically, you can use tap water, but there is a reason why new cars have no deposit build up and many shade tree mechanic's cars are crusty when you pull the radiator hoses.

 

i had this too, i figured it was just some mold or slim growing on the surface of the liquid in the tank so i just took it out and scrubed it. hasnt built up since then

 

Thanks for the reply guys I'm taking it to the shop for a flush and was wondering if I should give them any special instructions when they start to work on it. Or they should pretty much have everything under control?
