Even without a cap, you still have a drain plug at the bottom of the radiator, it will unscrew, and release all your water, then you have a separate resovoir for coolant that you fill it back up with, it will say coolant on it.
Add the coolant into the coolant reservoir. Be sure the engine is cool when you remove the cap off the reservoir.
"low coolant? sensor location, NOT "engine temperature" sensor location is of passenger side of radiator tank. remove headlamp assembly for a direct visual on sensor. it is a black plastic square on side of radiator lower than the upper radiator hose inlet. has a two wire connector
Technically, there is no fill cap on the radiator. To add coolant, open the overflow tank. It should be on the Passenger side fender, next to the windshield fluid tank. The coolant tank is pressurized when the engine is hot. Be very careful removing the cap to the coolant overflow if the engine has been running, since the scalding hot coolant can burn you.
No. The expansion tank will not let coolant drain into the radiator. Doing this will cause the whole system to be clogged up. WHO POSTED THIS MISSINFORMATION. OPEN A REPAIR MANUAL BEFORE YOU ANSWER QUESTIONS.
There is a petcock on the right side toward the bottom of the radiator that you must loosen. Also, disconnect the lower radiator hose. I believe it is an 8 or 9 gallon system. Refill the coolant by pouring it into the coolant tank, since Chevy has quit putting caps on radiators. Josh C
Originally this car had R12 refrigerant. It may have since been updated to accept R134a. The coolant/radiator system is not part of the air conditioning system. But the hot antifreeze-coolant is used for the heating system...
What year and make of car? My 1997 Honda Accord's radiator fan kept running after it was shut down. Upon inspection of my system I had low coolant and no pressure. Replaced the radiator and have not had an issue since. Check and top off your coolant, if it continues then I have no clue as to the problem.
There are flush-and-fill kits that Prestone makes. It might be more efficient to have it done professionally. I think the cap used on the coolant tank acts as the radiator cap since it mentions the pounds of pressure on the label.
Coolant and water expand as they heat. That is why there is usually an expansion tank on newer cars and trucks. That's where you top off your coolant leval (add coolant). If you are getting coolant out the overflow tube it's either too full or your thermostat may not be working properly. I have a ford van with an E-250 5.8 liter engine and if I add any coolant to the expansion tank it flows out the over flow tube on the radiator if there is no air space in the top of the radiator once the engine has reached operating temp. My solution which was given to me by a ford mechanic was to put no fluid in the expansion tank and to make sure there was 3/4 to 1 inch empty in the top of the radiator, also only top up the radiator from the radiator cap. to within 1 inch of the top. It has worked fine ever since, any time I add too much it automatically discharges it out the overflow tube.
On a 2003 Ford Ranger : Since you are asking this question I assume you have the 2.3L Dual Over Head Cam four cylinder engine . In this case the thread on cap on the engine coolant reservoir is your pressure cap / radiator cap The 3.0L and 4.0L V6 engines have the radiator cap on top of the radiator
It may have a bad temperature sensor. My 01 Escape radiator light comes on intermittently and I can't nail down the precise conditions. 3 different FORD garages have told me the sensor in the coolant reservoir is bad. Bad news is that to replace the sensor you have to replace the whole reservoir; good news is that it only costs ~$75 at Autozone. Since I know that this is the problem I just keep an eye on the fluid level until I get a chance to replace it.
It is the coolant level sensor that is located on the radiator just below the filler neck. This is a dealer only part. It costs around 25 dollars. Just disconnect wire plug and then detach retaining clip and pull out sensor from radiator. Some coolant (Dex-Cool) will come out which is normal. Then take new sensor and just push on till you hear a click which means the sensor is now secure to radiator. Then install plug and you are done with installation. Check radiator level and if low add some DEXCOOL only since you have a GM car that was made after 1995.
