1996 Regal: No heat, Radiator Fans wont work, Over heating.

1996 Regal 3.8L

1) Replaced leaking coolant bypass tube (elbow from belt tensioner to engine block)
2) Replaced bad AC compressor with a basic floater pulley.
3) Replaced serpentine belt.
4) Refilled / topped off antifreeze with 50/50.

Car now purrs like a kitty. However I now have no heat inside the car. Blower works, but I only get cold air on any/all settings. Test drove the car, and after aprox 1 mile car came close to over heating. I parked it, opened the hood with it running and noticed the radiator fans are not turning on.

I'm at a loss here. Any ideas guys?

If the thermostat is not opening then the engine heats up. So I would replace that first and then see about the fans not turning.

Hope this helps

SOURCE: Replaced bad AC unit with floater pully, now no heat, overheating

most likely when you replaced coolant line and refilled rad the system was not bled properly.
fill the system with 50/50 again and top up the reservoir. run the engine to 2000 rpm and look at temp gauge . it should rise to middle and drop to low this means t stat opend and air is out now let engine idle and top up coolant. good luck

You need to bleed the air from the cooling system. The bleeder valve is located just behind the water pump housing. It is a small hex head (7MM) screwed into the coolant bypass tube. Pour coolant into radiator with the valve opened until coolant comes out of the valve. The cooling fans will not come on until the temperature reaches 225 degrees.

The heater core on `05 Impala does not close when heater is turned off so does not benifit overheating by turning heater on.

My 98 buick regal looses coolant I have recently flushed system out, replaced water pump & thermostat but my I keep loosing coolant dont see any leaks i will fill it up & in a couple of days its...


Take look down by the belt tensioner. There are two by-pass tubes that run from the tensioner to the engine. The by-pass elbows have rubber seals on them and after the coolant flush may have damaged or ruined the seals.
The only other option is the coolant is going into the engine oil or transmission oil. Check both oils and see if they look "milky"
Good luck.

My heater not working, i replaced thermostat and radiator hoses, had radiator flushed and rodded, and still no heat. What is wrong?


Too much blockage in heater hoses or heater core.
Bypass valve may be stuck on "bypass" .

1. Remove bypass "Tees", but don't discard.
Replace with straight-through hose fittings.
The core may start leaking under the water pressure since there is no bypass hose.

Once the heater starts working, put Tees back in place. You need bypass protection or the engine will overheat.

1992 Honda Civic over heating replace theormostat - still overheating air bubbles in overflow jug and in radiator when running with cap off...


here is a check list for common overheating issues low coolant? Any leaks? A headgasket leak? To test that use a coolant mix tester. Do the cooling fans run with the engine hot? Is the rad cap holding pressure? This can be tested usually its easier to swap it with a working one or buy new. Lastly the waterpump and timing belt. If the timing belt if old/high mileage or the tensioner faulty it can cause overheating. The common practice is to replace the timing belt every 100,000miles along with the waterpump and the belt tensioner

1996 Buick Regal Sport - Leaking Plastic Elbow


YOU NEED TO REPLACE THE BELT TENSIONER.
IF YOU BUY THE CARTER BELT TENSIONER AT ADVANCED AUTO, IT COMES WITH: A PLASTIC ELBOW WITH O RINGS, TENSIONER, PULLEY, NEW O RING WHERE THE BELT TENSIONER MATES TO THE ENGINE BLOCK AND NEW O RINGS FOR THE INLET AND OUTLET CONNECTIONS ON THE BELT TENSIONER TO THE HEATER CORE (COST $72).
IF YOU DON'T REPLACE ALL THE ABOVE O RINGS THEN YOU CAN EXPECT MORE LEAKS.
IN ORDER TO REPLACE THE PLASTIC ELBOW YOU MUST REMOVE THE BELT TENSIONER ANYWAY. IF THE BELT HAS SEVERE CRACKS REPLACE IT ALSO.
STEPS:
-REMOVE BELT
-DISCONNECT BATTERY
-DRAIN ANTIFREEZ AND DISCARD
-REMOVE ALTERNATOR
-REMOVE BELT TENSIONER
-REMOVE PLASTIC ELBOW (DO NOT ALLOW BROKEN PIECES PLASTIC OR DIRT TO GET INSIDE THE ENGINE WATER CAVITIES.
-CLEAN ALL CONNECTION WHERE O RING WILL MATE.
-TO REASSEMBLE GO IN REVERS ORDER
-REFILL THE RADIATOR WITH COOLENT 50% MIX USE THE 5 YR GUARANTEE TYPE.
-MAKE SURE THE COOLENT RESERVIOR IS
FILLED TO THE HOT LEVEL MARK.
-RUN THE ENGINE UNTILE IT IT REACHES THE 1/4 % TEMP MARK ON THE TEMPERATURE GAUGE THEN TURN THE ENGINE OFF AND OPEN THE BLEED SCREW ON TOP OF THE THERMOSTAT HOUSING.
ALLOW THE AIR TO EVACUATE, YOU WILL SEE COOLENT COME OUT THEN CLOSE THE BLEED SCREW.
-BE VERY CAREFUL WHEN YOU OPEN THE RADIATOR TO REFILL TO THE TOP.
-REPEAT THIS ONE MORE TIME.
-RUN THE ENGINE AND KEEP YOUR EYE ON THE TEMPERATURE GAUGE' IF THE TEMPERATURE GOES BEYOND THE 1/2% MARK, SHUT DOWN THE ENGINE QUICKLEY AND LET THE ENGINE COOL.
THIS MAY TAKE HOURS TO COOL DOWN BUT THE COOLING SYSTEM WILL TURN FROM PRESSURIZED TO VACUUM AND DRAW COOLENT FROM THE RESERVOIR TO REFILL THE SYSTEM.
YOU WILL NOTICE THE LEVEL DROP IN THE RESERVOIR .
