Radiators

Most vehicles have a coolant reservoir (a clear plastic tub) with a phrase "engine coolant only" printed on the cap. This is where you should add engine coolant.

There are instructions in the manual. Take off the top cover and locate the bleeder screw, directly over the Thermostat. Loosen the screw. Add coolant to the radiator with cap off till full. Start the engine. When there is water coming from the bleeder screw, then wait a bit and tighten it . Add a little more coolant to the radiator and then put the cap back on.

Could also be a short to ground. If it runs all the time that's what it probably is. Get a wiring diagram and figure it out

the drain plug is usually located at the lower left hand/right hand side of radiator. I've noticed that some gm's and chryslers do not have drain plugs. in that case, it is easier to have a flush done.

Double-check first by turning on the air conditioning. The fan should come on immediately.

Use a volt light or multimeter and check that there is voltage on the switch (relay). On a 95 Chevy Cavalier, the relay is under the hood inside a black fusebox. The location is labeled "COOLING FAN" on top of the fuse box. The black cover pops off, and the relay can be unplugged easily. Pop out the relay and check the contacts it plugs into to see if there is voltage. There is a schematic on the side of the relay showing which pins (30, 85, 86, 87) do what.

Make sure the fan works by shorting pins 30 and 87, where the relay switch would normally short. The fan should spin up. If it doesn't, then the problem is the fan.

Otherwise it's a problem with the relay or the sensor?

Open the hood and look down. You are looking at the engine. There is a big metal thing that says "HOT" on it, covering the exhaust manifold on the side of the engine. If you stick your hand on the HOT plate when it is hot, you will jerk your hand back directly into the fans covering the radiator.

The radiator is the black thing behind the fans. The top of the radiator is the black thing that goes all the way across the front of the engine bay, and has a hose going to it on either side.

If you look in the front bumper, you are looking at the air conditioning condenser. Behind that is the radiator.

Radiates excess engine heat. Only used in liquid-cooled engines for obvious reasons.

Take it to a radiator shop or purchase a new one. I agree, and will go even farther. I would replace the radiator unless there was considerable savings in repairing it. The repair is only as good as the person doing it.

is your car equipped with a coolant overflow bottle replace thermostat have radd removed flushed and rodded

Remove and clean the petcock. Replace and if it still leaks, replace with a new petcock.

The easy way is to buy a flush kit from prestone ($7) and follow the directions. You will basically be splicing in a tee fitting that accepts your garden hose, and adding a can of flush to the cooling system. After 10 minutes of run time you will turn or the hose and 'backflush' the old coolant out the top of the radiator. Messy, but it works. I hope this helps you. Mark

When you drive the overflow is pressurized when the engine heats up. As it cools down, the engine will "drink" the anti-freeze out of the overflow reservoir. It is most likely making a sound like when you turn a milk jug upside down and let it drain? Chug, chug,...etc. A vacuum occurs in the overflow reservoir when the anti-freeze is taken back into the system and you are hearing the equalizing of pressures...like a milk jug.

the radiator is the same for automatic trans. and manuel trans. you dont use the inflow pipes ( transmission cooler ) for manuel trans. but two hoses r used if vehicle has auto. trans. to cool trans. fluid. it is ok to leave pipes open for manuel trans. as its not used

On/Off valves in radiators turned off or clogged Another possibility is an air bubble in the loop that services the radiators that are not heating. Correction is to bleed the loop.

You should drain radiator and then add a proper 50/50 mixture.

If there is no drain valve at the radiator you can drain the system at the drain valve on the boiler

Open the radiator petcock and drain coolant into a container. Dispose of all coolant properly as it is toxic to animals. Close petcock and fill system with water. Run the engine for several minutes with the heat on high. Drain the system again. Several repeats of this procedure will flush the radiator and engine for the Firebird.

It is a plastic screw on the bottom , front of the radiator on the drivers side. A quarter turn counterclockwise and then pull it out. Don't do it when the cars hot.

Ummmm, Radiator fans run off a temperature switch. Sometimes they put the fan switch and sender for the gauge together so I suppose it could be related. Have you checked to see if the wires are unplugged? Just a thought.

A leak in a coolant system can usually be fixed by replacing a hose. If the leak is at the end of the hose, a new clamp might be necessary. If the radiator is leaking, the radiator might need to be replaced.

Every five years or 100K miles.

Caution:On models equipped with Delco-Loc 2 or Theftlock audio systems make sure you have activation code * Disconnect the negative battery cable * Drain the cooling system * Disable the airbag system.Disconnect the forward discriminating sensor harness from the front fenderwell.It may be necessary to remove the hood latch mechanism in conjunction with the airbag sensor and secure them together and out of the way during the radiator removal * Remove the cooling fan assembly * Disconnect the upper and lower radiator hoses from the radiator then disconnect the coolant recovery hoses at the radiator neck * Remove the automatic transaxle cooler lines if equipped from the left tank of the radiator * Remove the hood latch support from the upper tie bar on the front of the engine compartment * Remove the right and left headlight assemblies from the vehicle * Remove the condensar mounting bolts from the radiator assembly * Remove the tie bar (crossbeam) from the engine compartment * The radiator can be removed from the top with some wiggling to clear various components
