Flush and clean the heater core. Also check your rad cap and maybe change the thermostat

Three are other factors. One situation I've come across over the years is the elctric fan that cools the radiator starts to wear which in turn causes it to stick. This fan due to it's location takes a real beating. Splashing, dust, bugs, and everything else. With a duel fan system, it can be one or both. Start your car let it warm up and observe the fan/s operation. If not this I would look into the relay, which is the second leading cause of overheating in my experiences.

Your water pump may be failing. If it fails (pump bearings, clogs, etc)your thermostast temp goes up because coolant in the water jackets of the engine are being heated to boiling, but not being pumped through the rad to cool. Also check the tightness of your belts, if they are loose, your water pump may not work well. Have you added water without adding coolant? Try a hydrometer and check the strength of your rad fluid.

Possible that head gasket could be bad. If you've done other things and still overheating. If your engine has got very hot in the past this could be your problem.With a aluminum head and cast iorn block these head gaskets can be blown very eaisly. If you run with this condition very long head damage will eventually occur.

A car can overheat for several reasons. You may need to replace your water pump. You may have a leak in the radiator itself. You may need to add more 50/50 mix of radiator fluid and water to your car. You could also have leaks or holes in the radiator hoses. You may also need a new cooling fan for the radiator.

Check the undercarriage for rust holes. My Bonneville would flood when it rained because of a small hole in the passenger side rear wheel well.

There are two types. If there are two scxrew holes in the face of the drum, run the appropriate sized screw into them and force the drum away from the axel. The newer ones require you to remove the nut and axel bearing, then it comes off easily.

It is on the bottom side or it is the line holes on the front.

Either the radiator hose is loose where it connects to the radiator or there is either a small hole in the radiator or in the radiator hose. Try checking the hose to see if it's loose or check for small holes in the hose or radiator.

You would lose the water/antifreeze mix in the system of course. If you think the hose or hose's are bad replace them.

You must drill the steam holes in the heads to coincide with the ones in the block or it will overheat QUICK!!!

most of the time this is because your radiator has sprung a leak. it can also be because your coolant hoses are corroded and need replacing. check all of the coolant lines coming from the radiator and that they are in good condition and properly attached to there flanges. then check the radiator for any visible signs of corrosion or holes. sometimes your water pump can experience wear and eventualy begin leaking through a small hole under it. Most of the time after running the engine you can take a flashlight and go under the car and see where the coolant is leaking from. follow any drips or liquid trails. if its a hose, simply replace it. if its your water pump, you can replace it or have it replaced. if its coming from a break in your radiator it is best to replace it. using chemicals to stop radiator leaks is a bad idea. auto parts stores will recommend it for quick fixes but do not use these chemicals. they plug up the holes for a temporary fix but also add debris to your coolant wich can build up in un wanted areas imagine if you started bleeding and you injected a clotting agent into your blood to stop it. you would most likely die. The best fix for this is to install a new radiator all together. they are in-expensive if you order them online.

the trans fluid on a auto trans goes through a tube in the radiator to cool the fluid if the tube has holes in it, it will leak trans fluid in to radiator. you need to replace radiator or have rebuilt.or you could put on a aux trans cooler and put plugs where the trans lines used to go.

They are installed in holes in the engine block where the frost plugs are normally located

Normally if you follow the top radiator holes to the engine should be right underneath the thermostat housing

Of course, it does. You can find it just in the middle of the engine oil pan.

there is a drain cock located on the radiator, it is on the bottom passenger side facing inside the engine bay. looking under the car below the radiator you will see holes on each side of the car (where the radiator sits) that is where the coolant will come out (pass. side) after draining you will need to get the air out of the system. on the top of the motor directly behind the water pump housing there is a spout with a 10 mm nut, loosen this and fill coolant in reservoir until water comes out of the spout. close spout and fill to line in reservoir. do this with the vehicle off so the water pump isn't on and the car doesn't overheat. good luck..

difficult to reach.facing front end,lower rt corner,backside of radiator,look or feel through holes in frame.rubber splash panel must be snapped loose for access.

Yes it could, a alternator has air passages in its case to allow for cooling. If those holes are blocked the alt. could overheat and fail.

New cars do not have drainage holes or anything like that. But you can purchase hand pump to suck out fuel of the tank.

The reason you buy water for you iron, is that you do not want calcium and iron inside your iron, as these deposits will plug the holes in the iron. Similarly calcium and iron inside your radiator wil cause the holes to plug up and stop the flow inside your radiator. You can buy demineralized water or use the old way of clean rain water.

Pass side are for Tranny Coller lines Driver Side are for oil cooler lines

sounds like the water pump is bad. there are 2 holes on the water pump. top and bottom. when it goes bad water leaks out of either hole, usally the bottom hole. since it leaks, the radiator cant hold pressure and it over heats. the resivor is where the coolent would go if the coolent over heated and when the coolent cooled it would get sucked back out in to the radiator again. the radiator has to build up pressure to open the spring in the cap to cause that coolent to release. since there is no pressure the resivor will always stay the same.

I take it hat the lines are leaking at the radiator. Check the flares on the inside of the flare nut. Use tread sealer on the treads. Look for any cracks or pin holes in the lines. Worse thing you may of cross threaded when installing the lines to radiator.

Toyota dealers will want $100 to $400 to fix these defective speaker covers there is no recall i checked. Its a $30 part per set. Rip the cover off (it will fall apart in your hand) bore out the holes put some kind of glue on the pegs on the new covers put pegs in holes and they should last until you trade it in./*

My 1990 Honda Civic Hatchback had a similar problem where it overheated on a seemingly random basis. I first replaced the thermostat, but that did not fix the problem. Then I replaced the water pump, again with no positive result. Finally, I replaced the radiator, which fixed the problem. As it turned out, the radiator had pinhole leaks that caused the problem. Also, when it comes to a leaking radiator, I do not suggest the 'quick fix' of additives to the radiator water that plug holes and stop leaks. These additives can cause more problems than they resolve. The best solution is to replace the radiator.

on the bottom of the radiator there is a plastic mount with two bolts on each side, removing them can be difficult if they are at all corroded. try not to break them when removing them, otherwise you will have to re-drill the holes and replace them with some bolts and nuts which is very time consuming. other than that just remove all hoses and transmission lines attached to the radiator and it should come right out.

there's two things you could check on your truck that causes leaks first check the watercontainer that is located on the passenger side, next check the holes that connects to the radiator. second is the bottom of your radiator check around it for cracks removed the cover to get a better view of the radiator. hope this helps you solve your problem good luck......

If you mean drain holes for coolant... There is one located at bottom of the radiator. And two more on each side of the engine block.
