    I have the same issue. I will check the radiator to see if it is clogged, is there anything else it could be? Is it possible to put the part back together rather than having to buy a new one?

There is no soution.The aftermarket pats are cheap plastic, and dont include the o-ring which is impossible to find. The ChevyAveouses the same engine, and part, butit is just as unreliable and unavailable. Three cheers for junk from China!

My 2000 daewoo lanos radiator cooling fan control relay is not work. what can I do

If the relay is bad, pull out the old one and put the new one in. You can test power to the relay and to the fan as well. If no power to the relay, then the fuse or temp sensor could be bad.

Daewoo lanos thermostat where is it so i can replace it, is there any difficulty in me replacing it myself? regards Matt

thermostat housing is on engine block, left side as you look at engine. Thick black rubber hose leads from radiator to the thermostat. Two bolts to remove, be sure to clean all stuck- on sealant so you get a smooth, flat surface when reinstalling thermostat housing.

You have clean the surface all parts and replace the seals so is the one way that not leaking, If you thermostat housing has two parts ot metal, if not, you have to buy another one with the housing more.

Computer not recognizing new oxy sensors and gas cap

On your way back to test put it in second or third gear and floor it probably needs a good clean out. Had one failed the smoke test myself a few years ago the man in the test center put it in 1st gear and floored it for about 10 min's around the yard. When it failed the test I told him I couldnt understand the fail as I never drove it hard or abused it in any way. He told me I was abusing it as it needs a good clean out. Worth a try as it work's for me all the time.

2000 Intrigue Oldsmobile over heating

I have a 2000 Intrigue that had the same overheating problem only when it gets below 0 degrees. I read many forums on this matter and it only got me more confused. It had thumping in the heater hose lines when it got hot. So here is what I did to cure the problem....I first installed a new thermostat that I purchased from NAPA Auto-$43. I noticed that it has a small one way valve built into the housing. I took a 1/8 inch drill bit and drilled down through the hole to make it a 2 way hole so coolant could get through (and air could escape when bleeding the system). I then took off the purge tank and flushed it out with hot water to get all of the crud out of it. When I reinstalled all of the hoses and thermostat, I coated the gasket seal and inside the hoses with high temp RTV. I also took off those wierd squeeze clamps and used the screw type hose clamps. I suspected that it was drawing air into the system when it cooled down and with the RTV and new clamps, that problem was eliminated! I reinstalled the surge tank and filled with 50/50 mixture of Dex Cool, then started the engine. I opened the bleeder valve on the top right corner of the radiator and left it open until a good steady stream of antifreeze came out. I kept putting antifreeze into the surge tank until it came up to the full cold mark. Then I left the pressure cap off and drove the car for about 10 miles at normal speed. During this time I had the heater running on high. When I stopped the car I added enough antifreeze to bring the surge tank level to full hot and put the pressure cap on. I then drove it for another 10 miles or so and checked the level, right on the full hot line. By the way, I also put on a new pressure cap. For $7 it was worth the money. I drove the car around for about another hour and the temp gauge only got up to a little over 1/4! Oh, I also put a new serpentine belt, just because the old one had 60,000 miles on it. So for $43 (new thermostat), $7 (new pressure cap), $12 (more Dex Cool), $24 (new serpentine belt), and $20 (new clamps, High Heat RTV, etc) the problem is fixed!! The reason I drilled out the hole in the thermostat housing was for air to escape when bleeding the system. This was the one and only time I have had problems with overheating, just in real cold temps, and I hope it never comes back! So for a little over $100 (MUCH less than a garage would charge!), you can do the same thing with a few tools.

Needing Thermostat housing

Of course. Ebay is your best friend. Well, next to me of course!

Here is the search criteria I used:

thermostat (daewoo, dae)

This brings up anything with "thermostat" and "daewoo" in the name, or anything with "thermostat" and "dae" in the name, just in case some spelled it "dae woo".

I also expanded the search to include store inventory.

Here is the one I think will work best for you:

or you can type in the item number: 370156811371

This guy has several and is selling them for only $45 plus $12 shipping.
It's advertised as being an improved design, metal instead of plastic. I'm assuming you had the plastic kind?

Double check the VIN numbers like he suggest and if it checks out, go order it!

Good luck! Hopefully this is helpful to you.

Daewoo lanos

yeah, the more I look on here the more I see what kinds of issues are with cars. You know toyota is a really really well built car, and they last a very very very long time when maintained correctly, changing the oil every 3 months or 3,000 miles, keeping tuneups yearly, changing transmission flluids as manufacturer recommended, and all those things. those cars and trucks are built to last. I owned a used 1974 toyota corolla once and when I got it it had 150,000 miles on it, and didn't need any motor work at all. I drove that thing in forever it seemed.. at least until it was totalled when it was wrecked, and I got more for the car from the insurance company than what I actually paid for it when I got it. I put a rear end in the car when I got it, brakes, and i drove it for like 2 1/2 yrs and put alot more miles on it than it already had... I put the odometer to over 300,000 miles from the 150,000 it had when i got it, and man that thing ran sooo goood. I blew a head gasket the second year I had it and the mechanic at toyota told me that the engine was soo clean inside and the head was in excellent shape valve wise that he wanted to buy the car but I woulnd't sell it to him. LOL. anyway, my point is, yeah toyota's are a little more cost, but they are sooooooooo worth the purchase if you are looking for a new car. Nissan is next in line afterwards. But I drive a Nissan truck now, and i would gladly trade it for a Toyota anytime at all. Even an old one... lol. Happy hunting for your new car.

Looking for thermastat housing

You are right indeed it is called a thermostat housing.

It might be sealed with a gasket, or o-ring, or it might be sealed with silicone. The small line on it is probably a vent for purging air ouf of the cooling system.

Sorry, I do not know any part numbers, but any Daewoo dealer parts department should be able to find you one in a flash.

Some aftermarket parts stores (NAPA, Pep Boys to name a few...) might be able to find you one too, but I`m not 100% sure on this one... Sometimes Daewoo parts are hard to find aftermarket.
