Not normally. If the heat temp GAUGE shows hot and the A/C blows warm you could actually be having a hot engine.situation. The heat GAUGE is controlled by the TEMP SENDER UNIT and has no connection with the A/C other than the A/C condenser rides in front of the radiator and catches all the debris first which can plug up the air flow to the radiator and cause the temp gauge to climb. If the A/C condenser is plugged by dirt and debris the Freon can't get cooled down enough to cool the cabin temp very well.
My suggestion would be to back wash the radiator and condenser. Use a high pressured garden hose and from the engine bay squirt the hose through the radiator and the condenser both to remove what you can't see. Be very careful not to bend the cooling fins of either the radiator or the condenser.

If i just put water and no coolant could this make my car over heat

No your car will not overheat, but it is advisable to my 50% coolant on the water to prevent deposits of rust and other debris that may affect the effectiveness of the cooling system.

Heat temp gauge on motor if faulty can it effect the cooling temp of the air conditioning on a saab 93 convertible 2002 model

No. The engine temp sensor affects engine idle speed, and timing. There is an in car temp sensor that controls the position of the blend door and the fan speed if the system has automatic temperature control.It also cycles the AC compressor clutch and the radiator cooling fans.

My 1996 honda accord doesnt heat up like it suppose to..unless its juss parked without any movement.. I drive it 2 miles away and it still doesnt heat up im concerned !! Any help ????

Thermostat stuck open?
Faulty temp sensor or gauge?
If heat comes out of the heater, engine thermostat is ok. That will isolate it to probably the temp sensor in the temp indication system (sensor & gauge).
The cooling system should be full. Temp sensors cannot read the engine temperature of steam or empty cooling galleries.

I have a 2008 Chevy Colorado and today my temp

when a temp gauge drops to cold ,it indicates a problem in the cooling system
temp gauge sender units need water to activate the resistance that makes the gauge read so a falling gauge indicates no water around the sender unit --- air lock in the system--faulty wire connection to the gauge sender unit
the ac unit is not connected to the temp gauge so there may be another separate problem there
the temp sensor is an entirely different unit to the temp gauge sender unit and the short term working would be from an altered coolant level from changing that sensor --air lock in system
the temp sensor connects to the ECM to activate the fans and monitor engine operating temp so as to keep the air/fuel mixture exact for the engine conditions
the temp sender unit just makes the temp gauge read
a faulty thermostat will either be stuck open and the engine temp will take a long time to rise or it will be stuck closed and that will cause an overheat very quickly

Temp gauge not registering and cooling fan's run continuously

the temp gauge works of a different sender to the coolant sensor. IT has 1 wire only and changes resistance as the water heats up there by moving the needle on the gauge up the scale Check that the wire is tight on the sender unit and if so then replace the sender unit.. The difficulty in re starting the motor may be because it is over heating but you would not know this because of the faulty sender unit.

98Honda CRV -Although there are no visible signs of overheating, the needle goes from medium-almost High - yet radiator etc appears okay. Could the temp gauge be faulty? Or are there some diagnostics we...

First i would check to make sure cooling fan is coming on if not check fuses.if good then check to see if its getting power and a good ground to fan. if it is the fan motor is bad. if not you my have a radiator coolant temp sensor not working right (not sending power to fan) but that sensor has to get power from The cooling fan relay... If the fan comes on. You need to have the cooling system pressure checked for leaks any air in system will cause the gauge not read right .It reads coolant not air if that ok there is another temp sensor just for the gauge it my be faultly it that ok a bad ground or faulty gauge. And make sure thermostat is good hope this helps

Car over heating when stopped in traffic but not when movin

Hi. the first test will be to open the hood and inspect the cooling fans. check to see if the fans are activating in intervals during the running cycle. if you don't see any fan rotation at all, this will confirm cooling fan failure and you will need to replace the fans or fan relay. Now, if the fans are running and the car is continuing to run hot when stopped, i would move to the next inspection point. the next problem spot will be a faulty water pump or faulty thermostat

If these two devices are malfunction in any way, it will cause the symptoms you are experiencing. at this point. the first thing is to make sure those fans are actually working.

Please rate and have a great day:)

2002 kia sportage temp gauge runs hot while driving

Cheak to see that the coolant fan is operating with the A/C turned on. The fan has to work to help the engine stay cool and help the A/C. When you apply heat on the control it acts to reduce the coolant temp. You will have to get the coolant fan operation checked. This can be :fan motor, fan relay, temp sensor and computer. Good luck
