Cooling issues - Page 2 - Infamous Nissan

may want to try flushing out the radiator and cleaning the fins (outside) as well, I cleaned the one in my former pathfinder using the AC condenser foam spray.

When the engine is running up at operating temperature, pop the hood, walk up and squeeze the top radiator hose. It should be very firm, and you should not be able to squish it by hand because of the pressure inside.

If you can compress the radiator hose, then your radiator cap is not able to hold in pressure, and you should replace it.

Old radiator cap (notice seal ring damage) on new radiator cap box.

Thanks to all for the continued comments-

I can say, I have regularly checked cooling bleed screw, one time leaving me looking like an idiot when it shot out like a bullet. So how many licks does it take to get to the center of a hot burning shower of glycol 50 / 50?.......23.....lol.

Radiator cap changed with Nissan OEM from dealer. Did that a couple of weeks ago.

Got WP, Thermo, and Electric Fan in route. Will flush when I complete the process.

Because of this site, I have deferred to buying mostly OEM parts for everything.

Both hoses firm when squeezed too-

Mine's temperature varies based on traffic flow. If I have to spend a lot of time stopped or at low speeds it'll climb up to about 3/4 of the way. Most of the time it sits about half way.

Damn, this must really be a common trend then. I thought I was the only one. I will say that I did change out the actual gauge one time. Damned thing showed 0 degrees on ride home. Homie wasn't going to play that, so that's when I changed the temp senders and noticed that wasn't the issue. Promptly changed out the gauge afterwards.

OldGreyBeast · 09-10-2015, 01:52 PM

Yep. That's one of the reasons I'd like to swap to an electric fan.

I sat with the engine running and the AC on yesterday, waiting to pick up my dinner for about 15 minutes, engine was already up to temp and had been running about 20 minutes, temp on the Autometer gauge stayed right at 191-192.

In my experience, if your truck is getting hotter than the halfway point at idle with the ac running, it has a problem. Switching to the electric fan is masking the problem, not fixing it. I would pressure test the cooling system, there is probably a leak somewhere. It can be very small and still cause a problem.
