Check to make sure your fan is kicking on this you can check easily by letting the car warm up and open the hood to see if the fan is coming on to cool the car down also check to see if your coolant is low if not then we dont have no leaks and were leaning more towards the fan scenario which could be a simple fuse.

Thanks,
Steve

Hi,
Check to make sure the thermostat is installed the correct way around. It's easy to get it wrong.
Bulb part should face the engine block - while the spring should be on the radiator side.

For the price of a replacement - just fit a new one the right way around. Use a new gasket and a smear of blue Hymolar to seal it. Use coppergrease on the thin bolts and don't overtorque.

03 beetle 2.0L.new waterpump and thermostat hardly any heat.return line going to bottle has no cooland comming out.the steel fiting on the side of the head seems blocked..is there a check valve in it


Turn on the heat in the car to full heat an full fan. Remove radiator cap start car and continue to fill overflow bottle/tank until heater starts to blow warm that's when the thermostat begins to open. Keep an eye on matter level -make sure it's full. Replace cap a wait 6/7minutes open cap slowly and with rag and gloves it will be hot. Slowly -continue to add more water. Until full. Replace cap. Shut off motor and wait until it cools about 45 minutes. Remove cap again and add water as needed. Then run
Motor making sure it is full. One more thing most important anytime filling radiator always turn heat on first. If not you will ruin your radiator as they don't swell open they swell closed as to not let water move thru it's internal passages.

2004 gmc savana is overheating


First are you sure the thermostat was installed correctly if so you have to have a blockage it could be that your new thermostat is bad it dose happen but again you sure the t. stat is not up side down dose your heat blow hot? probly not if lower hose is cool only thing left is the radeator is pluged look in it at cap do all the ports look open its posable your air locked you should have a bleader valve may be on or neat t.stat or on intake open itand run you can leave rad cap off or louse if at 200% its not sirculating i would pull t. stat out and run it with out one just as a test

My 1998 legacy is overheating, check engine light doesn't come on, could it be the thermostat?


Yes it could, but the cars have a bad reputation for eating head gaskets, so just to be safe, keep your eye on the temp gauge, don't let it over heat, carry water with you. and check for steam out the exhaust when driving, look for oil in the radiator, it will float to the top. A radiator shop can tell you real fast if you have a blown head gasket. We just did one here, found it easier to replace the motor than to do the heads. I have heads if you need them, J25. But on the bright side, could just be low on water. Your thermostat will usually make the engine run cold from being stuck wide open, If it gets stuck in the closed position, it will overheat, pop open the rad cap when warmed up, careful, look to see if the water is moving. If it is, the thermostat is open, will not overheat.

Overheating radiator without leakage


I posted this in a different web sight I hope it helps.


Re: Overheating and blowing cold air
I have been a mechanic for 20 years. Your problem is the heater core is plugged. The cold water from the radiator blows directly at the thermostat keeping it closed even when you are overheating! BAD DESIGN!! If you look at the water flow charts in AllData you will understand. If you rev the motor to 3,000 rpm's the turbulent HOT water at the water pump impeller (near the thermostat) will reach the thermostat to open it and the car's temp will fall very fast to the correct temperature. If you remove the thermostat it will not overheat but will run way to cold. If you bypass (loop) the heater core it will not over heat.

The hot water that leaves the heater core returns to the engine at the thermostat. It is the only hot water introduced to the thermostat to keep it open and allow the water to flow from and to the radiator. I normally just back wash the heater core and get large chunks of rust flake out then its fixed. Back wash then froward wash repeatedly many times. Also flush out the motor so you don't re plug the heater core. I hope you have now blown the head gaskets or cracked a head yet. Make sure to run the proper coolant in the car so you don't promote more rust flakes. And bleed the air out as mentioned in detail by other posters.

Nobody knows this little secret. Not even Subaru mechanics at the dealer, no TSB (Technical Service Bulletins a special note after the fact to mechanics). After days and days of trouble shooting a 1993 Subaru Impreza (2.0?) I looked at the water flow chart and then it was clear what was happening. This phantom overheating problem stumps the best mechanics and sends many Subarus to the crusher.

We just did the same car with the same prob. The block was cracked and was pressurizing the cooling system causing the thermostat not to open. Remove your thermostat and run the car if it doesn't overheat you need a motor. Ours didn't show any hydrocarbons in the coolant either, so try the simple

Water not circulating,we put on radeator cap water pump ,intake gasket,flush heater core,engine radeator,reservoir


check to make sure the bottom radiator hose is not collapsing. sticking together. once it sucks together its like the thermostat being closed. the faster the engine turns the it sucks together. also make sure its not the clutch on the fan gone bad. if it has one. to ckeck ,look under hood at fan ,have someone to rev engine. make sure the fan turns as fast as the engine turns . if it doesn't it's a bad fan clutch. goe put a new one on.

90 Subaru Overheating


Are you sure you don't have a head gasket leak? Are you loosing water? I have not seen the previous post you had, but I believe the air plug you are refering to is the one on the radiator. It is used to complete the coolant bleeding.
