93 civic overheating !!!

[djstorman]

Allright let me give ya the information.

I bought this civic about 2 months ago and everything was going fine except that the hose connect on radiator was cracked and broken.

My wife replaced the radiator and then I replaced the thermostat while I was fixing the car. I also recharged my ac which isnt working but that is another matter.

For the past 2 weeks the engines has been overheating when it is driven for more that 5 minutes.

So last night at around 2 am on my way home it started again and I dont know what to do ?

Also just another piece of information.

Before my wife changed the radiator we noticed that there was too much oil in the car. So after she replaced the radiator I changed the oil filter and drained the pan... There was no water in the oil.

So i need help I dont think its the radiator I just changed the thermostat so what could it be ??

water pump maybe. Are you losing coolant at all?

[djstorman]

my wife checked the radiator last week and said it was full today it was totally empty so I guess yes there is coolant loss. However there are no leaks when I look for any.

dunno your head might be warped

[djstorman]

Allright new developments.

I noticed today after I had finished driving the car for maybe 10 minutes that there was coolent loss in a steady stream not a quick stream but still a stream, from the left side looking foward of the engine. Dont know if it was from the engine but it was some where fromthat general area.


Is that the water pump or something worse. Help !!!!!

could be ur haed gaskey, i had to replace mine bout a month ago. Also check all ur hose connections and, put teflon tape on all ur threads that connect to the coolant system

[djstorman]

Is there a way to check to see if the head gasket is blown ??

like check the cylinders or something ?

[djstorman]

I guess I will test with a pressure meter and see if its blown any suggestions or tips for me changing my head gasket ??

what is up with "93" civic's this month. Mine is overheating too.. I notice my fan doesnt come on anymore when the temp gauge goes past 3/4's near H "hot". I don't know what caused it to go out? I check fuses hood,dash.. all ok. I the harnest wiring seems to be all connect too. I guess i have to just buy a new fan... Unless others have any other suggestions?

[djstorman]

My fan works so I am not sure what it is. Although I suspect it to be my head gasket dont know yet I guess I miht check with pressure tester

try replacing the relay for it.

allright here are the results from my compression tests

spark plug hole number 1- 180

spark plug hole number 2- 170 Water squirting out

spark plug hole number 3- 170

spark plug hole number 4- 180

So is my guess right when I say that the headgasket is blown between 2 and 3 ??

Need some information if you think this is correct.

Allright I finished taking out my exhaust and intake manifold. I am realy glad that I put in an extra 5 dollars for that can of bolt and nut lubricant/breaker. Going to start the head thursday. So any suggestions or tips. Also is there a way for me to see if I warped the head or would it be easier to take it into a shop ?

Also I also heard that if the head is warped that the bolts are going to be bent is that correct ? I am a true newbie so dont hold back give me all the advice you have. Thats it for now, thanks for all the help guys

[GScivic7]

if you have a feeler gauge or something like that, just run it along the bottom of the head and see if there is any inconsistencies. If there are, you can get it resurfaced (look in that the thread "higher compression?").

Check your thermostat: Heres how....

Warm the engine up until it gets hot. If the engine is hot and the upper radiator hose is still cool, then its your thermostat. If the upper radiator hose is hot, then the thermostat is fine.

If its not that, check for leaks. Another common problem is a faulty "fan switch". Its a metal piece that screws directly into your motor... located towards the back of the motor... kinda behind your distibutor cap.... and it has a plastic plug, plugged into the top of it. Honda retails it for about $45. You can buy a Mugen one for $50... but you'll have to get a Mugen Thermostat for $85 for it to work as it was designed to. The Mugen setup turns your fan on at 80, instead of 93 degrees.
