heya guys.

i just noticed that my car is losing coolant after i drive it a couple of times, its not much but you can definetly tell that the coolant level isnt what it was before

i just changed the headgasket like 800miles ago with OEM gasket

when say i drive like 2 hours, the coolant level on the resevoir bottle stays the same, it does not go up at all or down

i have changed the radiator cap with a brand new one and im running PWR radiator

waterpump and thermostat also has been changed like 1200miles ago

car does not smoke at all and there is no coolant burning smell

the only thing i can think of is the upper radiator hose, i notice that after i drive the car the upper radiator hose whole swell up on the bend that goes to the block

other than that i can not find any coolant leaking on the ground

please help me

 

up, help

 

Have you done a pressure test ? You can tell real quick if you have a hose leaking , radiator could be slightly cracked , etc . . . Have you also done a leakdown ?

 

i have not done pressure test yet, radiator is a brand new PWR and no leakdown test either

 

replace the radiator hose, check the water pump for cracks and check the weep hole on the water pump.

 

I have the same issue aftiner installing my Garrett T3 with coolant line.

 

bump, same problemo..

 

I usualy dont lose a lot, but lets say it dindt run the car for a day, when I let the car warm up like a minute or two I will see some coolant on the ground, I noticed It come from the back of the engine, I will chek more in details its a leak that is for sure but its weird that It happend after installed the turbo

 

just came back from driving the car, i noticed that on my upper radiator hose on the bottom part is wet

looks like im going to try a new upper radiator hose

 

Go try some of that UV light leak find....heard it suppose to work pretty dam good!

 

i have the same radiator as u and it was loosing coolant, no signs of blown hg, after a couple hundred miles it stopped, it was some nasty air pocket still in the system.
Bleed the system again

 

man i have bled the bloody cooling system for like a million times

ill do it 1 time when i replace the upper radiator hose

 

Make sure all of ure coolant hoses have clamps at each end. it may seem tight when its cold but at normal operating temps the hoses tend to stretch out a bit and may cause leaks.

 

oh and uhmm when you bleed the coolant system , does the car has to be on dead even road ? not a bit of angle at all ??

cuz my driveway aint completely flat

 

hey guys

my car still losing coolant slowly

i have changed both radiator hoses and changed all the clamps

ive done compression test, they all around 200psi~ish, leakdown test also has been done, when my mechanic did the leakdown test, he took off the radiator cap off and there was no bubbles what so ever coming from inside the radiator

we pressure tested the cooling system as well to 16psi, the pressure holds still

but the damn car still losing coolant

please help me, this is very confusing

 

are u running just straight water or is it a mix with antifreeze

 

mix with antifreeze, but unsure whether its exactly 50/50

bump for help !@!@#@#$@#

 

bump it again

 

Do you have any whitish residue anywhere around your motor area? That's a sign of coolant evaporating.

Most likely a coolant line somewhere isn't clamped down all the way good or it has a crack in the hose.

It may only show up when your beating up on the car and the pressure rises in the system but cruising it doesn't show up.

 

my coolant doesn't bubble until the car is warmed up.. i'm losing coolant all the time.. my catch can has a very nasty residue build up of whitish jelly crap..

any other ideas of what's going on? I dont have any clear signs of a blown head gasket, ie white smoke, puddles under the car etc.. this is getting very annoying..

 

do you have ARP head studs? aftermarket sleeves? watercooled turbo?


as for bleeding it you want to have the front end slightly elevated so that it is the highest part of the system

 

resurrecting this, looking for more answers. i am having the same problem, losing coolant with no leaks, im not over heating, no smoke, etc.

 

my car has always slowly lost coolant. id say i fill the reservoir up once or twice a week, maybe every 500 miles give or take. i contribute a lot of it to my aftermarket sleeves...

 

what brand of sleeve?

 

Your car is probably just burning it very slowly so you can't really see smoke.
