Mine is a slightly different issue. My car used to overheat only in fifth gear and only when going up a grade. Such as up a mountain hill for skiing or over the passes. Then it began happening in fourth as well.

The issue expanded to the highway. At highway speeds (interstate included) the same overheating issue occurs.

Recently, I have been overheating even just at idle or when driving around town regardless of speed.

Here's where it gets weird. The only way I was previously able to get my needle to drop and cool the engine down was to absolutely floor it. Ramp up my rpms above 4500 and then needle drops like a rock. This method is still helpful to an extent, but not for as long -- it almost immediately begins to rise again these days. Because of this, I thought perhaps I had an issue with the thermostat or maybe the valve due secondary to a failure to build enough pressure to open the valve and allow the coolant to flush.

I would also like to add that the car is absolutely overheating not just showing on the gauge. It is not an issue with the needle or thermostat as the car smells like its melting internally if I can't cool it down and keep it cool.

I have been to three different shops. I have done research and absolutely have not been able to solve or correct this issue. I am concerned at this point that my heads are warped (or getting there) and I may be at risk of throwing a rod.

Not sure if any of this is helpful, but thought id share just for another outlook and experience to consider.
go do a block test research alone isnt going to solve the problem. figure out if its a headgasket first. if not feel the bottom hose when it over heats and see if it is warm.

Default Winter Drive

Hello, recently a similar problem arose myself, I did not know how to solve it for a long time, I broke my whole head, but still I found a problem, I decided that I could solve it myself and it turned out, I just didnít want to go to the service, I love it means driving during winter , and now after the next pokatushek in winter, naturally in a very hard mode, four-wheel drive, the temperature of the cooling fluid began to rise sharply, after the problem repeated until I replaced the thermostat, which turned out to be fused, thanks for your attention, good luck
