The reservoir may be overfull. Fill to cold line on reservoir bottle.
Or, the radiator cap is not holding th epressure.
Or, worse case, the head gasket is blown and letting compression pressure from the engine into the radiator.

Why would a car overheat if the radiator has fluid and the reservoir is full and the antifreeze looks fine?


Coolant lines sometimes collapse which when the lines that hold coolant will suck together causing limited flow of coolant and not enough flow to engine so heater core yes but most likely no. in some vehicles you will see coolant on your passenger floor if it is a heater core I would say though its a weak coolant line that is sucking together look for one when the car is running

Beetle cooling


there will be no flow rate to the reservoir at all because the reservoir is only there to collect and excess coolant that is ejected after the water expansion from heat has overcome the setting of the radiator cap. The reverse of this is when the system cools down a vacuum is created in the radiator and a another valve opens allowing water to be drawn from the reservoir to keep the radiator full.. If you have a flow from the radiator when the engine is running check for failed cap or have a compression test done to check for blown head gasket or cracked head

Heater working intermittent


With the car parked on an even and level surface..

Check the coolant level in the engine compartment. There should be a reservoir that has markings for levels of coolant depending on whether the engine is hot or cold. Add a 50/50 water /coolant mixture to the reservoir to bring it to the correct level.

After the engine has been off for a couple hours
(cold), you should also check the coolant level in the radiator. Thi sis especially important if the reservoir was low or empty. Open the cap and start the engine, with the heat set to hot and fan to high. Watch the coolant level in the radiator as the engine temperature rises. If it is really cold out, you may need to rev the engine to 1000 - 1500 RPM to get it warmed up fully. Once the engine is at operating temperature, top off the radiator with the same 50/50 mixture you used for the reservoir. You should be able to see the coolant flowing in the radiator, and there should be plenty of heat now since there is no air in the system.

Good luck!

How do i remove engine coolant cap on 2001 cadillac dhs


WAIT UNTIL YOUR ENGINE IS COLD,YOUR RADIATOR PRESSURE CAP IS LOCATED ON THE COOLANT OVER FLOW RESERVOIR, THATS WHERE YOU ADD COOLANT WHEN COOLANT LOW,YOU POUR COOLANT IN THE OVER FLOW RESERVOIR UNTIL COOLANT LEVEL REMAIN AT FULL COLD MARK DONT OVER FILL OVER FLOW RESERVOIR, WHEN COOLANT LEVEL STOP DROPPING WHEN ADDING COOLANT AND COOLANT LEVEL STAY AT COLD MARK ON THE RESERVOIR YOU RADIATOR HAS THE CORRECT COOLANT LEVEL IF COOLANT LEVEL KEEP DROPPING CHECK FOR COOLANT LEAKS AROUND RADIATOR AND THE TOP AND BOTTOM RADIATOR HOSES, LOOK FOR COOLANT LEAK AT WATER PUMP GASKET OR SEAL OR LEAK AT WATER PUMP WEEP HOLE IF YES REPLACE WATER PUMP.

Coolant reservoir is overfulling after being driven


It probably got overfilled at some point. There's a max line on the reservoir that you shouldn't fill it over. Coolant expands as it heats up so if there's too much in the system, it's normal for it to overflow.

Car does not use antifreeze from the fill tank. I have to put it straight into the rad.


IT COULD BE A BAD RADIATOR CAP! EITHER CLOGGED, OR WRONG PRESSURE! ANY PARTS STORE CAN GET YOU THE RIGHT CAP!

Losing coolant from the reservoir but cannot see any coolant leaking on drive. Fill reservior to MAX and within ~10miles, reservoir is drained. Refill while engine still hot and don't lose nearly as much...


my '01 Jetta had a similar problem. I could always smell coolant and the bottle was always low. I crawled under the car and there it was..a caked on mess of pink antifreeze. There is a plastic intersection 3 way valve where the coolant temp sensor resides. it has 2 bolts and a rubber o-ring. Because it is plastic, it cracks. it drips down onto areas which are really not visible from above and then sizzles and melts onto areas under the engine. The part was only about $25, took 30 min to install and my problem is now fixed. Air was getting into the system through the small crack in the valve further complicating the system operation.

2000 kia sportage new heater core no heat


You most likely have air in the cooling system.You would need to bleed the cooling system of air.There should have bleed screws near water neck,or thermostat.Do this cold.Remove the radiator cap and fill full.Then start the engine and loosen the screws and watch for nothing but coolant to flow out(no air or bubbles).When you are sure the air is gone out of the cooling system,shut the bleeder screw off,and fill radiator up and test to see that engine runs cool,and you have heat at all speeds and rpm s.The electric cooling fan should come on at a tempuratue of about 215 or so.But just as important,the cooling fan should cut off at a lower tempurature.If the cooling fan does not do this,you still have air in the system.If you can not get the air out this way,then do this.Remove the radiator cap and reservoir cap and fill them both up full.The reservoir needs to be over the fill mark a good deal.Replace the caps.Start the engine with ac and heat off.Let it run until the engine gets to about 212 or 215 degrees and shut the engine off.Wait about 30 minutes and check the reservoir to see if the coolant has dropped.It should have dropped.If the reservoir has dropped or not ,do this again and again untill the reservoir drops in coolant level,and engine temp is good(fan goes on and goes off).Remember to refill the reservoir as needed as it drops,not to run out of coolant.
