I have a problem:
from one month after turning off my fd3s'93 touring, about 10-15 seconds after start bubbling and then pissing overflow from the tank behind the bumper.
reboot and you turn the light "add water" means the overflow tank full and I find it rather than caps and housing ast empty (sight).
What can that be?
ast the tank lho already changed with a steel.
tubes, aluminum radiator and 2 fans from 12"12v I ordered them.

The temperature marks just, not too hot either on the road, is also to a minimum after so long.
The engine runs perfect.


Help





p.s.: sorry for my bad english

 

check your ast pressure cap, i had a similar problem & it turned out when i bought my ast it came with a non spring cap.

 

the cap was 1.1 oem ..... the new ast wrote 1.1 ..... recommended cap with higher pressure? not rovino then nothing?

 

Pressure test your cooling system. You may have a leak somewhere and as the engine cools, you loose vacuum. That means coolant goes into your overflow tank but isn't returned to the rest of the system. That would also cause your "add coolant" light and buzzer.
Do not rely on the factory temperature gauge. Your probably low on coolant and/or have air in the system, so be VERY careful about overheating.
I'd also watch for any steam (or white smoke) on cold start-up.

 

ok thanks. Now mount plus radiator, new pipes and fans
12 "... then see if there are still problems....better still watching it seems that a pipe or the radiator had a leak ... we hope

 

I have cap by 1.1 ast pressure .... advised to change? that
again with that pressure should I take?

How do I change the thermostat? an exchange with an equal or
?

 

I don't think the the problem is your thermostat.
If you change pressure caps, I suggest a .9 bar one. They should not cost much and sometimes do go bad. You could also try changing out the other cap (with no spring) on the filler neck too
