I'm going to guess it's a head gasket. Have you checked your oil lately? If it's milk colored it's definitely a head gasket.

I have change the oil about 1200 miles ago. I'm going to check it.
I'm very paranoid about overheating the engine and I'm always checking the temp gauge, The car has never overheat, and I don't see any leak. How expensive/hard you think is to replace the head gasket?


Thanks.

if it is a head gasket problem and you dont fix it soon, you will need a new engine. i know because i've gone through the exact same problem with my last car.

Both expensive and hard. Unless you have quite a bit of experience doing head gaskets.

The truth. When checking the oil, remove the oil fill cap and look to see if it's milky on the inside of the cap and in the valves. If that turns up normal definitely take it in ASAP before it's too late.

to replace the headgasket you have to take off the intake manifold, runners, heads, and anything else to get alll the way down to the block of the engine ..

check if your car is smoking out of the exhaust.. thats usually a sign of it .. i believe white smoke

take it to your local shop or your mechanic and have him pressure test your cooling system and that will show if you have a blown head gasket

Bump.. Any word on what the problem was?

My car is doing the same thing, no smoke, no leaks, no evidence of evaporated coolant crust, oil is clean, radiator is full to just over the plastic shelf in the filler neck, yet I am losing about 1/2 to 3/4" of coolant from the expansion tank daily.

Cheers,
Paul

My 03 4cyl with 130k consumes a little, but my level in the reservoir fluctuates up and down, like some days it is more full than others. I need to put a piece of tape on the tank and start marking it to see whats up. Whats the difference between oil and coolant smoke?

color and smell:
smoke from antifreeze will be white and smell sweet.
smoke from oil will be blue and won't smell sweet.

The level in the reservoir will go up when your car is hot and will go down when the car is cold. That is normal.

Also the change in weather from hot to cold will make the coolant drop a little as you start to use the heater more.

It turn out to be a little leak in one of the upper corner of the radiator that leaked the coolant when the car was on and hot due to the pressure. its fixed.

I have a 2006 Accord 4cyl that is loosing coolant as well. I think there is a small leak somewhere in the drivers side lower rad area, but I haven't found it yet.

Just outta curiosity, what type of coolant did Honda use from the factory? What type of coolant should I top it off with? I haven't opened the resevoir yet, but it looks blue.

How was it "fixed"... JB-Weld, egg yolk method? :D Or...did you get a new radiator?

Glad it wasn't too serious.
