420A Overheating issue?

[Dsm_chuy]

I have a 420a 2g owned it for about 4 years now.

Ever since I had it, it would go up in temp. I’ve replaced (Water Pump, Thermostat, Temperature Sensor). Both fans work, no loss in coolant , no coolant leaks, radiator isn’t damaged, no smoke out exhaust.

What should I do?

Have you tried a new radiator cap? Solved my rising temperature.

First a question, how do you know it's overheating? The factory gauge or other confirming data since it's not peeing all it's coolant out?

Radiator car is a great next step but I'll also suggest pressure testing the system.

The stock cooling system is very capable. If it's running hot, there must be a problem with one of the components. I was running a plastic radiator with one fan, stressing the engine very harshly. I never saw high temps, but everything was healthy. After installing a 160 degree thermostat, the fan wouldn't even kick on with a 20-30 minute drive. I had to change the tune for it to function at all.

Point is, you shouldn't be running hot at all and if you are, diagnosis is required. It's definitely not typical.
