Looks like my red gt has started to use water. Does not appear to be leaking. Any one give a heads up on ware to start looking. Gricey

Could be a head gasket - any water in the oil. Is it steaming out of the exhaust pipe??

Oil is ok and no stem . Gricey

if it's only a very slight leak from the head gasket u won't get steam tho.
are u sure it's a 'leak' tho? i've seen them get a gut full of air in the system from not being totally full and it's creates an air lock. then when it's running the lock releases and the air goes to the top so the water level looks low when u check it again making u think ur losing water.
just a thought.

Thanks Brett. Rolling that idea also I have replaced the cap. Ran it and found it threw out the over flow. Gricey

is exactly what my old 351 falcon did too.
basically got hot enuf to push water out the overflow and made it worse coz u couldn't keep it cool due to the air lock.
I'd run it without the cap on, let it warm up completely at just slowly top it up till it can't take anymore.
see how u go then coz that should get rid of any lock.
oh and make sure the heater is on full hot too coz if that's empty it'll make another lock when it's turned on again.

Good advice Brett I will get at it to day. Gricey

Heater?



Oooh that's right it is cold down south.....heh heh

Hey Gricey,
I've fitted a recovery bottle to the Florian because every time the motor warms up it pushes some coolant past the cap through expansion. Just find a bottle that fits (A Triton ute one for Mary), connect the tube from the overflow & fit a recovery type cap. (Make sure it reaches the contact plate - The throat is deep.) As it cools down, it sucks the liquid back.
Wow, all moderny!
This prevents the green wee or rusty mess, depending what you run in there.

Cheers, Matt.

Hi Gricey, make sure you have the right radiator cap with the longer reach neck, had this problem years ago and found the cap did not seal the radiator properly.

ah yep good point with the long reach caps lads! fell into that trap myself.
new caps are easy to get. CPC brand, part no. 507/07 is the one u want.
coz they only use a 7 pound cap, maybe a new one is in order anyway as this prob mite just be water being pushed out without much pressure in the system?

Did about 50k on the week end ran with no cap and heater on. Put on a new cap . Seems to have stopes using . Gricey
