okay,
im losing coolant,
i have 0 leaks, (i checked all hoses)

symptoms :
drive car around in the morning 30 minutes to work - no problems.

drive car home from work - 30 minutes, and when i get home im loosing coolant, its basicly boiling inside the radiator resivoir tank, and the water is spraying/spewing out of the top of the resivoir tank,

this happend to me this weekend i waited a few hours and the radiator was empty, so i topped it off, and yesterday it did it again,

the temp gauge isnt rising, im not using ac

shrug its annoying.

 

Could be anything.
Does the fan(s) come on?
Could be bad thermostat, bad temp sensor, bad water pump.
Start with testing the theromstat and work your way up the price scale.
Could also be internally blown head gasket. Check for coolant in oil?
What other symptoms?
Is there coolant on the ground anywhere?

 

is the water pump functioing correctly? I had a similar issue & my water pump was leaking like a sonofa....

 

check your gounds mine did that same crap it was from weak ground

 

Possibility of a Blown HG? Do you get a white puff of smoke on acceleration? do you see any bubbles in the coolant (when you first start it, steady stream)?

Good Luck

If it werea headgasket he would have drivablility problems too, as in car backfiring a lot, dieing, pretty much anything that lost compression will yeild. I personally think its just the hot texas weather, I am not too far from ya man, I am in Duncanville, and I know how hot it is around 5 and how nice it is in the morning, lol.

 

yeah thats kind of what im thinking

i just got dynoed 2 weeks ago and im putting down 156 so i dont think have any compression issues.

i just checked the oil, solid gold color, just checked coolant and its green, no oil,

im going to beat on it the way home and see if it happens again texas is hotter than **** i dont know what happend to the coolant that was in there this weekend but im guessing that i overfilled it sunday and thats why it was doing that **** yesterday so today will be a test, i checked the resivoir tank and there arent any leaks.

 

damm i just realized that it was 106 degrees at 530 yesterday
lol its ******* hot

i need ac

 

I agree that that is hot but, you still shouldn't boil coolant out of radiator. There has got to be something restricting coolant flow or air flow thru radiator. I have heard of race cars using the stock cooling system and not overheating.
Was your coolant mix 50/50?
Bad water pump impeller?
Do you get heat inside the car from the heater. And, not the sun?haha.

 

if i turn the heater on i get heat.

before it was mixed 50/50 now its just straight up coolant.

 

100% coolant is worse than 100% water.
Causes corrosion and has a lower boiling point. Could be the problem?
Add water quick.
Well,other than that, I'm stumped.
Anyone else, got any ideas?

 

Is your radiator cap good? I had a very similar problem except my car was slightly overheating. But it was due to the coolant coming out from the overflow tank. I replace the cap, and it's never done it again. Also this is in my HF with a B16.

P.S. I'm replacing my compressor this weekend. It took a crap out on my 3 weeks ago. Damn it's hot going home at 5.

 

Hmm, I made a post a couple days back ago of why my coolant bubbling ( https://honda-tech.com/zerothread?id=562026 ). I took of the cap to bleed the system and the coolant started boiling a little. I never have a problem with it over flowing when the cap is on and my car is fine, compression is good and I don't burn oil and there is no oil in my coolant or coolant in my oil. People said I have air in my system but wouldn't all the air bleed out and go in the reservoir tank ?

 

my car did(does) the same thing but i think its because i have 2 issues .. one i have an aftermarket "catch can" and my fan doesn't come on? the catch can fills up and spits that crap right out. but it rarely over heats ??

good luck

 

well, i made it home yesterday with no leaking, and made it to work today with no leaking, maybe it fixed it self, im going to keep an eye on it though.
