Outer Limits 4x4 Board

gday, some more advice needed+appreciated,

i own GQ 4.2td n/a (diesel)

my problem, for last few months the coolant in my over flow keeps dissapearing in very short amounts of time, 4-5 days.radiator always seem to stay full...

i got a new radiator cap (genuine nissan) and looked for traces of water in oil but nothing.
any one have any ideas or lead me in direction of repair......?

today i took it for a thrash to heat things up a bit, got back ppopped the hood and a few traces of fresh coolant under radiator cap lid and on hoses but very minimal?

if problem is leaks how or where do i get this checked and what kind of prices am i looking at to repair this problem?

Talk to mr. radiator... those guys have reasonable prices and a good enough service... or if you have a local mechanic that you are friendly with then just see if they can give it a check over for you.

have a look at your overflow bottle. They are shite in the GQ, and deteriorate over time. It may be leaking itself.

If youre worried you can get it pressure tested, but make sure engine is at operating temperature or more, so everything has expanded into normal running conditions.
