Radiators

the one on the radiator

Most antifreeze has a chemical that freezes at a very lower temp than plain water.

Your heater core is leaking. It needs repaired or replaced.

Most cars should be able to handle this themselves, older cars you use a small hand pump to suck air out from either the radiator cap or the coolant tank cap respectively.

You should check the fuse, and also do a computer diognostic. You could need a new radiator fan relay or wiring or diode wiring, or a new fan altogether.

I have a 1999 Blazer and I was looking for the radiator drain plug as well yesterday. mine appears to be broken but it is located on the passenger side of the radiator near the bottom edgeon the engine side you might have a small black rubber hose coming of of the area of the drain I think this is supposed to make collection of the coolant easier. The drain is plastic and should look kind of like a wing nut. You also get the best access to it from inside the wheel well by moving out of your way a rubber skirt. Its still not easy there is not much room. I have read others have just removed the lower hose to drain the system. I know that makes a real mess.

1. Turn wheels all the way to the right.

2. Lift rubber flap inside passenger side (right side) wheel well to access white plastic drain cock

3. Place 1/4" drive rachet into end of drain cock and rotate 90 degrees (1/4 turn) counter clockwise

4. Remove rachet and pull white plastic drain cock outwards (towards firewall) to release coolant

Good Luck.

Bottom drivers-side, engine-side corner of the radiator. A total pain to get to and there's part of the frame in the way, so coolant gets everywhere. (This is from experience gained within the last 30 minutes.) It's also plastic and can break if you're not careful. Some recommend disconnecting the lower radiator hose on the other side instead.

It does not sound like a head gasket to me. I would check the oil if you see clear bubbles or it is foamy, in my experience that would be a blown head gasket.Is the floor on the passenger side wet=heater core is bad. Are you losing water? Where? Did you replace the thermostat? Hope this helped.

that's where you put it...just fill it up...and it will go through your radiator

could be a bad water pump or the thermostat. i would check the thermostat first for two reasons one its cheaper some where between 8 and 15 dollars and also more likely to fail

The cap is on the coolant reservoir (driver's side behind the battery), not on the radiator itself as in many other vehicle makes. Mine is yellow. DO NOT remove cap if engine/coolant is hot as system is pressurized.

Replace the fitting.

You need to burp the radiator and cooling system.

Easiest way to drain the radiator is to remove the lower coolant hose.

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 solder it with silver solder.

However, in general the only real solution is a new radiator.

if your in a bind and your desperate and just so happen to have eggs available keep in mind that you can throw a couple of them in your radiator when its still warm and the eggs will cook and when they do they will fill the cracks a little so you can limp it somewhere, no racing.. hope this helps... oh ya do this while its running for those of you with less common sense than us other people

Overheating problems are caused by clogged radiator, non-functioning cooling fan, defective thermostat, defective water pump, defective or incorrect radiator cap, clogged water ports in engine, or collapsing radiator hose.

I PAID $170 FOR MINE IN VA

I paid $125 for a radiator online. Installed it myself.

Remove the lower radiator hose.

When this problem happens I would always replace the stat first.Make sure you bleed all the air out of the cooling system by allowing the car to run at idle for about 30 minutes with the rad cap off.

Bottom corner of the radiator, facing the engine, typically opposite end of the radiator from the lower radiator hose.

It can prevent coolant flow, which can cause a catastrophic overheat.

Wrenches: 10 mm, 12mm and 14 mm.

It is beneath the lower radiator hose.

Assuming there is coolant in the engine

the most likely cause is a build up of sediment behind the coolant drain

or in the coolant drain tap itself.
