Question about 2004 Chevrolet Impala

1 Answer

My car started overheating. I was almost out of antifreeze, but my reserve tank still had antifreeze. Put a sealant in the radiator believing there was a leak, as well as the 50/50 mix, but it still ran hot and overheated. Could it be the water pump?

Not likely water pump unless pump is leaking. You need to figure out where the antifreeze leaked out. Can you see anything leaking with radiator full and engine running? I have some tips at http://www.fixya.com/cars/r5929960-s_thermostat if you want to troubleshoot. Let me know if you have questions.

I have a Mini cooper 2002 model, Its not overheating or anything but the water level in the Reserve tank goes very low to nothing in the reserve tank, what would be the cause? I cant see any leak visible...


It could be a slow leak in the radiator or hoses or the head gasket. The antifreeze could be blowing out of the cylinders rather than leaking to the ground.

Overheating and trying to locate the radiator and the reserve coolant tank. Don't know which is which?


The radiator is usually the black tank in front of the fan. It has a silver cap (DO NOT REMOVE WHEN HOT!!!) that you can take off when the car is cold to check if there's fluid in it. The reserve coolant tank is usually a white plastic and has a hose in to that connects to the radiator. It is used to catch the extra fluid that comes out of the radiator when it warms up becasue coolant expands when it's heated. The reservior should have two marks on the side of it. One for "max fill" and one for "add". Add coolant to it if it is below the "add" line. If it's extreamly low, you'll have to add coolant a coulpe times to level it off once air gets out of the system. Your best bet is to remove the radiator cap, top it off with the right antifreeze (you can get this pre mixed) and replace the cap. Then fill the reservoir with the right antifreeze to the max fill line and drive the car until it gets warm. About 10 minutes. Then top off as necessary. I do NOT recommend using plain water to do this. If you use water it can freeze and do extensive damage to your engine. Go to your local auto parts store and ask them for the correct antifreeze. Ask them how to mix it or purchase the pre mixed kind.

Leaking water from radiator and overheating


The overheating problem is due to the leak. Radiators are suppose to hold pressure and it is Pressure that changes the Boiling point of the water.
Without the Pressure the water will vaporize at a lower temperature and you will not get good cooling. You could also have a clogged system. Also test the Radiator cap.

There are several ways to try to fix this. Radiator Sealant, Rebuild your Radiator, or buy a new Radiator.

The sure solution is buy a new Radiator. Rebuilding one is a little cheaper sometimes, but you may pay someone to put your old parts on a new core. At best, the bad spot can be braised and the rest of the Radiator is good. Buy a new one and do it yourself. You are not paying someone and getting back used parts this way.

Sealant- If you do this you should clean the system first. They make a Coolant system cleaner. Then get a really good brand of Sealant. Not a K-mart item but something over $15 and sold only at NAPA or ask the Dealer. But you will have invested about $25 in cleaner and Sealant with just the Hope of success.

Since antifreeze is over $8 a gallon you need to think about the best way to keep it in the truck.

Have 2002 Ford Escape, Where's the Radiator Cap??


This is where you fluid goes. If I were you, I would stay away from those sealants. But yes you can put the sealant in the reserve, but it;s best if you drain half the water out, pour in coolant and then re-fill. This gives it a better chance to flow throughout the system. Sometimes these sealants can cause more harm than good in the long run.

1995 ES 300 - antifreeze is draining from reserve. took to a mechanic who did diagnostic. said everything was fine. said no antifreeze in radiator so he topped off. 2 weeks later, the car is running hot...


Is the reserve tank cracked or have a deteriorated hose going to the radiator? Remove the tank to find out. A bad seal on the radiator cap can also lose fluid. A coolant leak anywhere can deplete the coolant level in the radiator and reserve tank. Check your owners manual for antifreeze type and mix ratio with water.

will pepper swtop a radiator leak
Improvement done by sickofjunk
There are radiator sealants available at many auto parts stores. I personally have never been able to get them to work though another good way to seal a leak if it is on the aluminum part of the radiator is to soder it with silver soder. And no i don't think pepper will stop a radiator leak.
