Hello and thanks in advance for any help. My Saturn aura is the 3.5 and it the tempature started to fluctuate when I drive from a little above half way then will rise to 3/4 and sometimes it will go back down to normal where it’s a little below half way.
I replaced the thermostat then the water pump which the water pump was out … yesterday I replaced the radiator because it had a crack in it. As of right now the car is not leaking coolant but the same issue is still occuring .
I have pressure in the system now I noticed it when I cracked the cap open to hear any hissing sounds … I already bled the system and flushed out the block but now I’m stuck … Oh and also when the car gets to hot and I release a little pressure the resavoir will go down a little .
Thanks for any help .
