I need cooling help... please!

This is long because i'm being descriptive. Please try to help... this has gone on long enough.

I absolutely cannot figure this out, by my cooling system is ****ed up. It seems to spit all its coolant into the overflow tank and not suck it back out. So after a couple of days, my radiator is empty and my reserve is full and I'm running hot.

I went and had the system pressure tested, and it was okay -- he even gave me a new cap... same problem. Today, I was pissed. I'm sick of my piece of **** car. It's been the most unreliable vehicle i've had. I got home and took off the cap while the engine was still hot. (Used a towel and was careful). SO much pressure and steam came out. Steam?

After i let all that out slowly I had the cap off, i then started the car w/ the cap off. It violently boiled out of the top mixture of air and coolant, violently bubbling out the top. So i turned it off and proceeded to fill the radiator to the top and drain my overflow tank.

PLEASE help me here. It's not that complicated of a system. I'm wondering now if my headgasket or orings are shot and i'm getting compression pressure into the coolant. However, I have never seen any white smoke or smelled anything sweet (both typical if you're burning coolant).

I have to assume there arent leaks in the sysem because it pressure tested fine and i've seen none, but there is always pressure coming out of the overflow hose. If I shut it off, and open the overflow tank, it is bubbling because air pressure is leaking into it.

Thanks,
Shane

I keep trying little things, but the problem is so damn intermitten it's hard to tell. Maybe I have an air pocket somewhere? I have never bled the system. Could that cause this problem?

Okay.... been reading about a blown headgasket, and that has to be my problem. ****ing thing that sucks is that I (somewhat) recently had the valves rebuilt and they obviously had to do the headgasket.

I found this:
Quote:
Testing an automobile engine for a blown head gasket is pretty straightforward. The first check is to see if there are combustion gasses getting into the cooling system. Take a sample of the coolant and go to the local radiator shop and request that they analyze the coolant for the presence of hydrocarbons. If they are present then it is most likely that you have a blown head gasket.
Has anyone heard of that?

Ran the car w/ the radiator cap off and the coolant has a foamy appearance coming out of the return line. I can gas the car and watch more come out quickly.

If you had a HG issue, oil will be present in the coolant and coolant will be in the crankcase. Not to mention the car will run like ****. It was pressure tested fine right so the HG is probably not an issue unless you drove home with the car overheating.


-Is the thermostat working? When was it last changed? It's cheap so might as well replace it.
-Did you bleed the air out from the block? The bleeder bolt is on the top of the thermostat housing. Let the engine cool off COMPLETELY. Remove the radiator cap and top off with coolant mixture. Leave the cap off and start the car. Crack open the bleeder bolt on top of the thermostat housing. Top off with coolant mixture if needed. Close the bleeder bolt once no more air comes out. Top off with coolant mixture if needed and close the radiator cap. You coolant system should be bleed. If you still need to top off with coolant fill through the overfill tank.

Question is why would you take off the radiator cap off when the car is HOT?

how many miles do you have on your car? maybe you need a new water pump
Check the lines that would suck the coolant back from the overfill tank. Also you should be able to visually see if your headgasket is blown, the coolant will have a mixture of crap, oil, etc.

bleed the system
ive never had to bleed it either but it might help.

its pretty rare to have a blown head gasket espically if you dont see oil in the coolant. seems like your not getting any suction which could be the thermostat. it sounds like there is pressure but no where for it to go... check the upper radiator hose and make sure that it is not clogged

Wow guys. thanks. you have reassured me some. I've not seen anything in my coolant ever, it's always clean. It was just coming out foamy from the return line. The thermostat has been replaced within 10k miles, so i dont think thats it. I will go bleed the system now.

Thanks a lot for advice!

I'll let you know how that turns out.
Shane

did you replace the thermostat with an OEM Honda one? When I had my Rx-7 I replaced the thermostat 4 times and the last I used an OEM one and it fixed the problem

Do you need to change the fan switch also when doing the thermostat? Shane, are your cooling fans clicking on?

Oooo! I bled the system, and it took about 15 minutes maybe a little more, but now it's a solid flow of fluid coming through there w/ no more bubbled !! I'll have to drive it for a couple of days to be sure, but it certainly looks better. Thanks a lot guys!

One other quick question... does the type of antifreeze matter? I've got about 1/2 Oreilly's antifreeze (mixed w/ water) which says it's okay for aluminum engines. I've also got some valuecraft 50/50 predelluted in there. It doesnt say anything about aluminum either way :shrugh: Looks the same?

I assume most any antifreeze is okay, but i'd like to conform.

Thanks again,
Shane

I do love my car... BUT it sure has cost me a lot of money

To answer some above questions. My fans are coming on, but I did replace my fan switch recently.

The thermostat i put in was just an autozone generic -- but works

I have 105,xxx miles

I heard it's not good to mix your coolants because different brands may have different formulas. Is this true? I think I remember reading it in helms not to mix coolants either. someone correct me if i'm wrong, I'm curious myself. I've just never attempted to mix.

You could buy that new coolant that claims it mixes with any coolant

I've used pre-diluted/any-manufacurer coolant and it works just fine. My temp guage stays below the half way mark...always. I also live in a state with 90-110 degree summers.
