Hi, I drive an Acura 1.6el (1.6 sohc vtec) with almost 250,000km.

I tried to do a search but wasn't able to find anything.

A week ago, I lost all interior heat in my car, then after my car started overheating. I brought my car in, and changed the thermostat. Everything was fine for 2 days, then it started happening again, my heat stopped working, then my car started overheating again.

I checked my coolent level, and it was a bit lower, I noticed there was coolent in my engine bay, but I thought that had something to do when my engine temperature was at maximum.

Any ideas as what it could be? (gaskets, waterpump, etc?)

 

heater core is clogged, its stopping the flow of coolant causing the car to overheat. you can test this by bypassing the heater core.

 

can this cause the coolant level to go down?

 

and how do u bypass the heater core

 

it can, however it could also mean a blown headgasket if your losing coolant. then again sometimes a blown headgasket can cause a heater core to get clogged, too, by letting oil into your coolant and the oil could help clog it.

First step id do is bypass your heater core. if someone could find a writeup that would be great, but ill try and explain it as best i can. You take the hose from the thermostat housing to the heater control valve. and you re-route that hose to the outlet under your distributor.

Someone please correct me if im wrong, this is how i bypassed mine. no problems since.

 

hmmmm goddammit ok ive had symptons of a blown hg for a month or two now, my car still seems to run fine doesnt seem like ive lost compression but sometimes my temp acts up and i get the no heat thing too, but when i refilled my rad its fine again i also dont blow any white smoke but ocassionally smell coolant in the cabin sorry not to thread jack but im frustrated lol

 

I know this sounds a bit weird but Honda motors are notorious for getting an air bubble trapped in the head mainly. Have U flushed the cooling system or opened other than the radiator cap? If U lost interior heat it could also mean there is no water in the core @ all. I've had the same thing happen to me in the past. As crazy as it sounds, I've had to remove the radiator cap, push the selector all the way to heat (don't turn on the fan), crank the car & let it idle, place a jack (yes a jack) under the right front corner of the car & lift it about 8 inches or so. As the car idles up to temp, keep topping off the coolant as the thermostat opens & closes. This sounds a bit drastic but I've had to do this more than once to more than 1 car. This usually will burp the air bubble out of the head if there is 1. Good luck & happy new year!

 

do you have a collant resivor bottle for the radiator???

This is the answer. Mine recently had air in the system (flushed coolant) and the exact same thing happened to me. The coolant in the engine bay is most likely from the engine overheating causing coolant to force its way past the cap on the reservoir.
