Hi!! I have a 92 accord with 250,000 miles on it..its been well taken care of. My question is I have been having issues with my temp gauge sensor.Car would start...went to junkyard picked up a new "pig tail"(whatever its called) and spliced it in. Great! now the car starts and seems to be registering the temp normally. I noticed the other day that i was extremely low on antifreeze(i just replaced hoses and drained (not flushed) system. How hot does the engine have to be before it starts flowing ? Just concerned cause i was so low in antifreeze . Also added more again (very little)the other day in the overflow.
I just need this car to last..trying to trouble shoot problems.
Thanks Guys
ps no antifreeze in oil

 

Single poster...nope Im not wasting my breath. Anyway, by flowing...do you mean through the radiator? That would be 180ish, when the thermostat opens. It flows through the engine all the time though.

 

Well I'm on here to try to help so here we go.

If you just replaced hoses and that - these can be tricky to get all of the air out of the cooling system when you re-fill it. Did you use the coolant bleeder when you re-filled the coolant.....you should have had the bleeder open/out and the heat set to max (this opens the heater control valve and will get the air out of the heater core). Then you slowly add coolant to the rad until a good stream of coolant is coming out of the bleeder. Then close the bleeder. There are a few more steps but this is the one that many miss.

check the coolant level in the rad when the engine is cold. If low add coolant. You should also check for more/other coolant leaks.
