Coolant *OVERFLOWING*

[t3ase]

Okay, this has happened twice now. I just opened my hood to go at installing JoeP's MBC and noticed a boiling bubbling type sound in one of the radiator hoses. I look over to the coolant resivoir and it's literally overflowing with coolant.

I just drove the car for probably 30 miles in 98 degree heat. No racing, straight driving with max speed of 80mph. Any ideas? SpicyMSP couldn't tell me and the dealership is closed.

[dominoy2k1]

possibly thermostat?...dunno its really weird...did you notice temp gauge readings?

[t3ase]

Normal... I turned the car back on and the coolant slowly came back down to the regular level.. I then turned the car back off and it didn't happen.. WTF

[boostisgood]

joo got a block somehweres, or the car is just REALLY REALLY overheating. my bet is on a a block somewhere, This can include inside your engine block, in the cooling jackets.

Mine does that too. 3 or 4 times now. Just another "characteristic of the msp" :mad:

The car runs way to hot here in NM. I'm gonna try ION fmic and a normal 2L protege radiator. I think that will cool her off.

[Striker187]

yeah check your thermostat switch. btw, did you notice if your fan was running? at idle or at speed?

[Striker187]

yeah check your thermostat switch. btw, did you notice if your fan was running at idle? could be an indication of a thermostat problem.

[t3ase]

Car was turned off as the coolant was overflowing. Fans were off.

[Apexi]

might've blown the hg

[t3ase]

Uh.. Why would that cause the coolant to overflow?

[Apexi]

uh, because it is fairly common when you blow a head gasket

[t3ase]

Right. Thanks.

Anyone else? :D

Not sure why your car should do something like this, but here's my two cents on trying to keep it from happening again:

If you're always in hot areas, why not use more water than anti-freeze, like a 60/40 mix, and some Redline Water Wetter? Not extreme, but it might do the trick.

If that doesn't help, does anyone know of a mazda radiator cap that would be slightly higher pressure? We used to use 300ZX radiator caps on our SR20DEs or DETs in Sentra SE-Rs and G20s. It helped cope with advanced timing, the lack of EGR and the extra heat of turbos...

I need to be more polite to people. I do consider this my first warning, if I am warned again the mods will spank my bitch ass with the mod stick.

[t3ase]

:rolleyes:

Anyway, thanks for the suggestions. Car's going to the dealer on Monday to get the Kenwood HU/dash surround piece replaced. I'll talk to them about it since it's happened again.

[soundbombing]

redline has water wetter. use couple cap fulls of that, 15% coolant or something like that, and DISTILLED water. look @ our rads and look @ any other protege. tell me what's the matter when you find see what i'm talking about.

plus our lovely oil and water cooled ball bearing turbos have to use the same boiling hot water from our extra small rad. and our boiling hot oil from our extra small qty. of oil/oil pan.

Coolant overlow is normal. Don't worry about it!!! That's what it's designed for!! Now about the higher pressure radiator cap, I have the Mazdaspeed radiator cap that is rated at 1.3 bar. I also have the Mazdaspeed lower temp thermostat. These may be hard to come by due to Mazda not shipping Mazdaspeed parts from Japan anymore because they are developing thier own here in the US. I had to wait for months before my thermostat came from Japan via Corksport.

i think this is an opportunity to upgrade to something aluminum

I don't if its only me but any excuse to upgrade things :cool:

Coolant overflowing through the closed resivoir and onto the engine bay paint, out of the car is normal? Not in any other car I've driven.

(hmm) That's different. How full is your resovoir?

[MSBlueP]

quick question: What kind of engine coolant should I put in the MSP?

[Yay-Boost]

I purchased the Mazdaspeed 1.3 bar form corksport. They had a Greddy one listed on their site that was $10 cheaper. I tried to order the Greddy and they said they had been backordered for a long time. My stock one was leaking so bought Mazdaspeed. It stopped the leak and the extra pressure is supposed to help with boiling inside the engine. Redline has a tech article about coolant that is really good. http://66.54.67.96/whitePaper/17.pdf It mentions coolant boling over after hard driving and shutting down fast, but this doesn't sound like what happened to you.

[Kooldino]

Yeah well I have a scratch on my car, so I thought id post and complain about it, cause I dont have a brain to think for myslef and figure out what to do with it. Also my car is dirty and the interior is really messy any ideas on what I should do with that...Oh and "I mean this in the nicest way"
??? He's posting a problem and trying to figure out a solution, and seeing if anyone else has had the issue. WTF is your problem?

[chinaman]

FBI14 is dumb; he has to ask what a clutch slipping feels like; yet he acts so smart on the forums. (pow)

[Antoine]

stay on topic...you guys are doing the right thing by ignoring it!

Thanks

Guys, keep in mind this thread was from August of last year. Someone used the "search" button and brought this thread back to life.

Here's an answer to one of the Q's. The reason a blown HG will cause the coolant to overflow is because the cylinder pressure is introduced into the coolant system(depending on where the HG blew out). The coolant system isn't used to 130+psi, so it blows the coolant out.

[YP5 Toronto]

Sounds 90% like a blown head gasket......I have been there with one of my past cars.

If you have blown a part of the HG...the presure created in combustion is pressurized throught the adjacent coolent system. Hard to explain....but that is what is happening with your coolent.

...its sorta...leaking inside...versus have the HG blowing outwards......

[YP5 Toronto]

doh....I feel dumb....I only read the first page.... ignore my hasty post

Doh! I didn't notice that. Guess I'll delete my post.

Depends on the climate where you're at...

So, if it was boiling in the coolant reservoir and leaking out while it was closed, that's a sign of a blown gasket? Reason I ask is that this was before I even had the JoeP installed. I noticed recently that I'm consuming a bit of oil, so now that you say that, it concerns me.. I know a blown head gasket will cause coolant to leak but I didn't think it would cause it to come out of the resivoir bottle. Nothing was leaking out of the radiator itself, only the reservoir tank.

[YP5 Toronto]

It could be a small leak happening across the smallest parts of the HG....that being between the cyclinders. This type of problem is tough because it is not as evident as a "full blown" HG. Under heavy pressure (load) the pressure is forcing AIR into the coolant system...and the only realease for this pressure is through the coolant tank...hence all the coolant in the engine bay area. The radiator is solid...so nothing is going to come out of that area.

Consuming oil is not a good sign....whether the car is NA or FI.

What color is the oil? does it look milky? I don't think the HG is damaged to the extend that you are loosing extreme compression....you would notice that.

Get a compression test done.

[t3ase]

Oil was still a purple color at last change, so it's not being contaminated at all. (Royal Purple oil is purple for those who haven't used the stuff) I was just a bit low last change.

[DSM2MSP]

Why not do a compression test and maybe even a coolant leak/pressure test? Easiest way to determine leaky headgasket/blowby.

ok so if you have coolant coming out the top of the reovoir tank, I have never seen it come out but there is crusty residue all over the top, then that means I could have a blown head gasket?

[LinuxRacr]

Yeah, I plan on talking to AWR Racing about an aluminum race radiator.:D
I may as well show you my progress on the subject. :D
