Coolant doesn't heat up!

Hello ayo, that information is simply not true. I think the Honda engineers know more about their cars than yours does. If your cooling system is clean and all the componets are working as designed, the thermostat should not need to be removed. In fact, i have seen many cases that when the thermostat is removed, it causes the engine to run ever hotter and overheat. The reason being, with the thermostat out, the coolant is circulating faster, it passes through the radiator so fast that the air coming through the radiator fins don't have time to cool it before it re-enters the engine. If you are in extreme heat this is what i suggest you do. Thermostats come in different heat ranges, which means they open when the coolant reaches a certain temperature. You can replace yours with a cooler one. If you have a 200 degree install a 180, or one that is 15-20 degrees cooler. Always run a clean mixture of 50/50 coolant. keep your radiator clean inside & outside and the cooling fan blades clean and turning freely...you should have no problems.

Good luck, hope this helps & thanks for using FixYa!

this is probibly a blockage in the radiator or water pump issue start by flushing the radiator,then check that water is flowing thru the radiator and water system.

the thermostat could be bad ,not opening up to make the flow of coolant threw engine,you have switch on the bottom of radiator unplug the 2 wires with key on jumper the 2 wires if fans come on that switch could be bad or thermostat not opening to let coolant threw system

if your sure there is no air pocket hiding in the coolant system,pull the thermostat back out so the coolant doesn't have to reach 195 degrees before letting the coolant flow thru engine,and see if it still over heats,it might be an air pocket or head gasket,doing this will tell you exactly.

Most Hondas and modern car fans can and do run at will. 215 on a scan tool is just reading the sensor and variation is ok. A temp gun is more accurate. Ill bet your gage is still normal. I have a honda and the fan runs at times when I get out. Normal

That is normal but on the "long side" of normal. If the engine temp is good while driving, the temp sensor may be slightly out of range, but if its either very hot outside or the engine is running hotter than normal that can influence it as well. That part, you have to consider as I can't see what is going on there.

you have to bleed the system coolant

When an engine is overheating and then the temp drops on the guage, it's usually a sign that the coolant is not touching the temp sensor. There's no coolant in the engine. Putting water in the overflow tank won't solve this. Take the radiator cap off after the engine cools and put coolant in the radiator. you might have to crank the engine and do this several times, as the engine can develop air pockets that won't allow the coolant to travel inside the engine. If you don't see any leaks, and it still uses coolant, you've probably got a blown head gasket. Check for water on the plugs, check cylinder compression. If it slowly uses coolant, try putting a large box of pepper in the radiator or some of that radiator seal copper flakes.

It does sound like the thermostat. The sensor does not control the thermostat in any way, it only reads the temperature of the coolant. Your symptoms are classic of a thermostat that is stuck open or partially open. Take it back and tell them what is going on and have them show you that the thermostat is fine.
