right when i turn on my civic i can turn on my heat and it is already hot after about 30 seconds. not really sure why. it leaks or burns a little coolant too. and it over heats every now and then but goes back to normal. kind of like the thermostat is bad, but when it does this it is usually a little low on coolant. but whey does it have heat instantly it makes no since, its 30 degrees outside.

 

dont understand it heating that fast but sounds like u need a hg

 

yup running a car while its overheating is not smart. replace the headgasket before you need to new head/motor

 

I WISH MY CAR WOULD HEAT UP THAT FAST!!!!!!

naa....im with those guys ^^^^^
