what would happen if in case you fill it out with tap water above max level? i mean FULL.. is it bad for the radiator with 1.1 cap?

 

help me on this one please... thanks

 

It's used as a overflow from your rad, having it full defeats this purpose. wont kill ya but you should drain some.

 

is it possible that temperature will rise? coz it seems that it's not overflowing.. i don't see water coming out around the cap of the reservoir..

coz i noticed that my temp goes up (3/4) and goes back to normal especially when driving at night with or without traffic... replaced thermostat, fan automatically turns on, no leaks whatsoever... this happend when i saw my reservoir full...

dunno if it's the waterpump or just the sending unit though...

 

or maybe lack of ground....

 

seeing as you replaced the thermostat it sounds like a watter pump issue, mostly cause it fluctuates, thats probably your pump trying to keep up. Do you ever get out and touch the head or block to see if it was really hot when your temp gauge is going higher? try that because if it does not feel abnormally hot your gauge might just be screwy, happend to me once.
ohh ya... if you have a d series engine you should be able to touch the head when it is at operating temp and keep your hand there, I can't on my b16, its too hot. do you have a D or B?

 

also sometimes your rad dumps watter into your res and then can't draw it back, open your rad cap and make sure she is toped right up.

 

Do you have any leaks?

 

not meaning to hop on ur thread with my own question. but my reservoir gets empty fast. i filled it and a week later it is empty. my radiator is topped off so idk whats up with that. and no leaks.

 

Have you replaced your radiator recently? Did you bleed the air out properly?

Check thouroughly for leaks, also check your head gasket.

 

no clue. just bought the car, doesnt look like any leaks or anything.

 

yours more than likely is the head gasket, your losing coolent into your oil and it's burnt out via white smoke and watter comming out your exausht.

When checking for a blown head gasket, one of the most common tell-tale signs is a milky-gray ring around your oil cap. When coolant enters the engine oil through a crack in the head or through a blown gasket, it evaportats and leaves a milky ring around the oil cap. Another easy way to tell is to check your oil dipstick. Change your oil and pull out the dipstick. Make sure that you take note of how far up the dipstick the oil is. Top off your cooling system and fill your cooling resevoir to the top. Screw radiator cap back on and start engine. Run engine for about 20-30 mins. or until it reaches normal operating temperature. Allow engine to cool (engine must cool completely to get accurate oil reading!!). Check oil dipstick again. If the oil has a watery appearence and has risen noticibly up the dipstick, the you probably have a blown head gasket or a warped head. Also look for a dripping, sweet-smelling liquid coming out of your tailpipe. Any of the above symptoms could be the result of a blown head gasket. The easiest way to tell is with a compression meter. This replaces the spark plug and lets you know what compression each cylander is running at. If your compression is abnormally low, then you have a blown head gasket or a warped head. (note: consult repair manual for appropriate compression of each cylander.) <---- off some site

 

b16a, yeah ill have the water pump check.. or maybe it has somethin to do with a worn out head gasket...

no leaks, bubbles or somethin... also, it may be a faulty temp indicator...


guys by the way, im still using oem 2rows radiator plastic top.. not aluminum nor copper...

 

this i must definitely try... thanks for the heads up...

 

that was for choys problem dude..... sigh

 

oh.. but it may be of lil help since my brothers ek encountered the same problem... choys reservoir lasts for a week.. but with brother, he refills it every 2 days...
