04 Pathfinder Overheating issues
Posted: Mon Oct 13, 2014 3:09 pm
Hi Guys, I'm new to the forum and looking for some help with my 04 Nissan Pathfinder. It started overheating on a 2 hour trip through hills. I lost power when it overheated as to be expected after not seeing the temp gauge rise. I pulled over at that point.
I let it cool, I filled the rad with antifreeze and water. I drove it cautiously the rest of the trip, this kept happening up hills only. As it got hot I would pull over and let it cool and check the fluid levels, there were a couple times i needed to add rad fluid again.
Took it to the mechanic, they changed the thermostat and another spring loaded pressure part, as well as the rad cap. Its still overheating. They let me know that the issue is something else that that they cant take care of and they said maybe its a really small pinhole in the engine cooling system somewhere as a result of me driving it when hot?
Is what they are saying, possibly true? what would be my next step in fixing this overheating problem. It seems to be okay driving in the city and at low RPMs but nothing more then that.
I must add that I'm a foreigner living in Costa Rica. so I don't have a mechanic here that I trust and I'm not sure there are Radiator Specialists in this country that Ive found yet.
Thank in advance for any advice!
Cheers,
Cory
