My Coolant keeps disapearing.

[TheProfiteer]

I dont get it, my coolant keeps disapearing somewhere.
I checked all my coolant lines no leaks, so then I think oh no, head gasket.
well oil and coolant are not mixing and I am not getting any steam out of the tail pipe. Ive got it so the fan is always running, plus I am running with out a thermostat.

What else can I check?

[uproot]

check your hoses may have a leak in one... also is one or both hot or cold after running the car..

and check your radiator, i kept losing coolant too... turned out to be my radiator, put a new one in and no more problems

[TheProfiteer]

yeah both coolant lines are the same temp, I took the thermostat out so its constantly moving through the radiator, plus the fan is always running.

I have a spare radiator, so Ill try to and check it ou.

[NevrNufTorq]

if the head gasket is just barely gone then it will go out the exhast and you wont have any in your oil. had that issue a couple times.

[uproot]

or maybe one of those damn "caturday" cats are stealing your coolant at night when you're asleep...

my rad cap was bad and it was boiling over my overflow tank. I lost almost a whole gallon within a few days.

[TheProfiteer]

I think its the water pump, oh well nothing I cant change, but its gonna be a bitch :headslap:, especialy getting that damn harmonic balancer off with my weak compressor

but then shouldnt I be getting steam on a cold start, or high revs?

[1SOL2NV]

lol ... also check your TB lines ... make sure to rev the car up a lil .... mine didnt leak until i was on the throttle a lil bit .. then started flowing out ... dry rotted hose ...

buy a pressure tester kit. You'll need an air compressor, but you just hook it up, sit back and wait for it to spew out w/o getting the engine super hot.


if very minimal is leaking out over a long period of time it's going to be a hard leak to find. but it prob. will burst eventually (if its a hose)

I second this...check the radiator cap. A lot of people over look this...just like me a post before. lol

I just reaplced a blown head gasket in my car + had a warped head and I didnt loose compression, have mixed oil/coolant or smoke/steam out the tail pipe. It just ran hot and built up alot of pressure after driving about 20 mins. I never lost any coolant though, that I noticed untill we got the car apart and saw it in the cylinders.

[IDriveToast]

Do you have an antifreeze reservoir tank? Do you have the hose running from your radiator to it? If you do not, when your antifreeze heats up the pressure causes everything to expand which makes the spring on the radiator cap compress to release pressure. If the antifreeze is too hot and it is boiling the evaporated vapor will escape out the vent there and into the atmosphere versus into the reservoir to condense.

[TheProfiteer]

yes I have the reservoir and the hose on it,

is the pass floor board wet? maybe a heater hose

[AnthonyF]

is the pass floor board wet? maybe a heater hose


usually if the pass floor is wet its a heater core. but...could be anything. check everything everyone has said in here!!

[Gutling]

if there is no coolant anywhere in engine bay, from water pump or hoses or anything, more than likely headgasket. slow leak-wont get in oil, probably wouldnt see it coming out the exhaust (light white smoke)

[iEvo]

yea ur radiator cap does more then just seal. is ur car running hot at all?

[TheProfiteer]

I changed the radiator cap and everything seems to be fine. been driving 3 days and taking it up to around 5k with no loss of water.
