Question about 1996 Buick Skylark

1 Answer

What controls the radiator fan on a 1996 Skylark?

I put a new radiator and hoses on this car, it had a small crack and pinhole in the plastic part of the radiator. I have never seen it run hot and isn't now, but, I haven't seen the fan come on yet, when should it run, and what cotrols it? Relay, temp switch? It runs when hooked to a battery, just don't see it coming on when the car is running,, only seeing 180 degrees at the therostat neck, heat hand stays a halfway.

Electric fans are controlled through the ECM by a coolant sensor in the lock
when it registers water temp at a preset temp setting , it reports to the ECM which then activates a relay and the fans run
the set temp is close to the opening temp of the thermostat
there are 2 fuses in the circuit so check them if the fan /s is not working automatically

SOURCE: 1996 buick regal over heating

Hi,
This sounds normal to me..... Except "runs to hot when idling"

When you're driving about (airflow over rad) all seems fine, but when sat in traffic idling - the fans come on to cool. Is the problem that even with the fans running, temperature still goes up - and fans never turn off again?

Is this the problem?

If it is, then the coolant pump may be badly corroded, not driving efficiently, or the coolant needs flushing and replacing.

SOURCE: Low Coolant light flashing on 1996 Buick Regal 3.8

The low coolant sensor should be located in the passenger side radiator tank, You need to take it out and clean the sludge off of it for it to work right. Or you can just unplug it and forget about it, the light will go out and it won't cause any problems.

SOURCE: 1990 BUICK CENTURY RAD.COOLING FAN RUNS ANYTIME KEY IS ON.

If you have changed out the relay, and disconnected the temp cooling sensor, make sure you have replaced the correct relay; I believe there is one bank of four relays located by the passenger side head lamp. If the fan is running continuously, then I would say the relay is stuck in the closed position, resulting in completing the electrical circuit, powering the fan. Have the new relay tested. You can find a wiring schematic in the Hanes manual for your make and model.

Where is the radiator drain on a 96 buick skylark?


Not all radiators have drains. The only way to drain some is to remove the lowest hose. If you wish to flush the system you could remove a hose anywhere in the system (with heater control set to hot) and insert a garden hose to inject fresh water through a COLD or slightly warm engine.

How do i fix a crack in my radiator in my 1996 chevrolet cavalier


Is your radiator Plastic and metal? or Just metal? where is the crack? Can you see the "crack" or can you just see it leaking antifreze? It could be a hose clamp leak,or small hole? At this point without knowing that it is a crack for sure ,all I can say is check hose clamps ,they also sell a product called Bars . Any auto parts store has ,it seals small radiator leaks ,be sure to follow directions on bottle! I would recommend changing the raditor if your keeping the car,or really depend
on it,they like to go bad at the worst possible times!

My subaru legacy outback goes on normal tempertaure for about four miles. Then overheats. Drains the radiator of water. Why is this?


Hi there must be a cracked hose somewhere in the cooling system if its draining the radiator of water, i would also check the radiator side tanks as the plastic ones become brittle and small cracks appear that are quite hard to see

How do you change the radiator on a 1996 Buick Skylark?


GM Grand Am/Achieva/Calais/Skylark/Somerset 1985-98 Radiator - REMOVAL & INSTALLATION
CAUTION Never open, service or drain the radiator or cooling system when hot; serious burns can occur from the steam and hot coolant. Also, when draining engine coolant, keep in mind that cats and dogs are attracted to ethylene glycol antifreeze and could drink any that is left in an uncovered container or in puddles on the ground. This will prove fatal in sufficient quantities. Always drain coolant into a sealable container. Coolant should be reused unless it is contaminated or is several years old.
A cross-flow radiator is used on most models. The radiators used on automatic transaxle models are equipped with oil coolers with inlet and outlet fittings for transmission fluid circulation. An aluminum-plastic radiator can be identified by the black plastic side tanks and aluminum radiator.
  1. Disconnect the negative battery cable.
  2. Drain and recycle the engine coolant.
  3. If necessary for access to the radiator, remove the air intake duct assembly or air cleaner assembly.
  4. On automatic transaxles, disconnect and plug the upper oil cooler line.
  5. Disconnect the engine strut brace at the radiator, loosen the engine side bolt and swing aside, if equipped.
  6. Matchmark and remove the hood latch from the radiator support.
  7. Detach the upper hose and coolant reserve tank hose from the radiator.
  8. Disconnect the forward light harness and fan wiring. Remove the electric cooling fan. On some models this may not be able to be removed unless the front end of the vehicle is raised and supported.
  9. Raise and safely support the vehicle.
  10. Remove the engine cooling fan if not yet done.
  11. If equipped, remove the splash panel below the radiator outlet hose. Detach the lower hose from the radiator.
  12. If equipped, disconnect and plug the lower oil cooler line.
  13. Carefully lower the vehicle.
  14. If equipped with air conditioning, remove the radiator to condenser bolts. Unbolt the refrigerant line clamp. Do not disconnect the lines.
  15. Remove the mounting bolts and clamp, then the shroud (if equipped) and carefully lift the radiator out of the engine compartment.
To install:
  1. Lower the radiator into position.
  2. Install the mounting clamps and bolts, including those associated with air conditioning parts.
  3. Raise and safely support the vehicle.
  4. If equipped, attach the automatic transaxle cooler lines.
  5. Connect the lower hose(s) and attach the splash shield if equipped.
If the engine cooling fan was removed while the vehicle was in the air, install the assembly and attach all electrical wiring.
  1. Carefully lower the vehicle.
  2. If not already done, install the electric cooling fan, then attach the electrical connector(s).
  3. Connect the upper hose and coolant reserve tank hose.
  4. Install the hood latch and strut brace.
  5. Fill the system with coolant.
  6. Connect the negative battery cable, then start the engine. Run the vehicle until the thermostat opens, fill the radiator and recovery tank to their correct levels, then check the automatic transaxle fluid level.
  7. Turn the engine OFF , then once the vehicle has cooled, recheck the coolant level.
