Engine Cooling problem 4 cyl Front Wheel Drive Manual 84598 miles

Hi there, I have this Honda Civic 1996 5dr hatchback.
i have recently noticed when I am either in motion or idle in my car mostly the car is fine the temprature is normal. Suddenly sometimes it start rising nearing the red but never goes on red drops back down to normal. The fan is working I have checked it, topped up with coolant, Also noticed the coolant has to be topped up every so often but no leaks were found. Had a full service done recently an they didnt find any leaks, smell, or any boiling etc. Just concerned if I burn the engine. What do you think could be the cause of this strange overheating suddenly? The engine has been checked through by a pro - Mechanic. Any Idea's?
Do you

Hi There, Just recived a message regarding my Honda Civic 1996 4cylinder hatchback, I will get the Themostat changed asap. I have another question in Regarding Overheating problem. My temp gauge is mostly normal sometimes rises an falls back to normal, fan's etc are working fine. Does the Water pump need to be changed aswell or do you think the pump is fine? Much appreciated for you previous reply thank you very much.

One way to test for a bad water pump is to squeeze the upper radiator hose when the engine is hot and idling. Careful, because the hose will be HOT! If you do not feel much coolant circulating through the hose when you rev the engine, the pump may be bad. The other cause might be a bad thermostat that is not opening properly (remove and inspect the thermostat), or a clogged radiator.

Hi there, I have noticed that my Coolant after long drives the coolant dropped down alittle. Is that Normal? I done a journey 400 miles Traveled there and back an next day I checked an topped up 500ml water coolant level back to normal. This time it never overheated in the temprature gauge. Any Idea's as to if there is any problem in the Coolant system? Thermostat was fine thank you.

Hello there, I have recently had my car in the garage an checked by a pro mechanic. An he says systems running fine as normal the gauge has to move up an down once in awhile. But today as I drove an the engine's gauge moved up an then back down to normal as I turned engine off there was a boiling bubbling sound coming from the overflow tank. Does the car need bleeding is air stuck in somewhere? If so I have to erge my machanic to do so an see what happens. What is the best course of action to take? Any idea's is good enough for me.

Could be air lock if not get it block and pressure tested

Get him to bleed the system if it continues have him do the block and pressure tested.

Hello there once again, ive just recently had bleeding and the radiator flushed with 50/50 Antifreeze an water added afterwards. Also done the Block an pressure test it was fine from the looks of it. My machanic told me to check after a day or 2 the water level to see if I am loosing any coolant, I realized I have lost a very little amount after a Day passed and no leak can be found even with cold engine. Temp gauge stayed normal but from the looks of it very soon now the coolant will be low an it'll start overheating on the gauge again. I also noticed each time I brake or turn the steering when driving down the road the coolant Light turns on (red colour light on the dashbored) about 2 sec's then stops sometimes appears other than that its fine. Its very difficult to find this problem what things am I Missing? I mean the car drives very smooth an returns good MPG. I am hoping to keep this car for awhile. Any help will be Much appreciated Thank you.

If the temperature gauge is not out of calibrated and you don't have a boilover indicating overheating I've given you the best I got on dealing with overheating -terminate your parts changer mechanic. Or have him contact me in here to explain himself Something still wrong with it. Its not being diagnosed right

Ive recently Noticed after putting fresh new Antifreeze/water 50/50 mix the water does not evaporate, as far as I remember there was only water without antifreeze. Another thing I realized the Engine oil was running very low an has now been topped up to the correct level. System's Running fine. It must of been my clumsy mistake not to have checked properly, So sorry to have been Bugging you with so many question's I really appriciate your patience thank you. Take care.
