94Eg

Hey i have a 94 dx civic sedan and my engine is over heating . The car is all stock and when was driving today all i saw was it jumped up over the middle reading . after i got to work I refilled the engine with antifreeze and on my way home it did the same thing. also i do hear some noises from the engine. I think i have a small leak or i don't know can some one please help me .

thanks

Good ol' Screwtape

What kind of noises?
Any CELs?

check for leaks and make sur your fan is coming on. i had the same problem and it turned out to be the fan switch which is located right by the thermostat

The noises sound like cliks and clangs also when the car is off it sounds as if peices are snaping because it is colling down. i don't think any cels .

How many miles are on the car? ever replaced the thermostat? How long does it take to heat up? when u park ur car for the night, put newspaper under it to see if you have any leaks. Might have a cracked core. mine did so i just replaced it. now i think it cools it tooooo much.

the noises are prolly various metal parts that are too hot cooling down. metal does that.

i don't believe that thetheromast was ever changed and i only have 96,700 miles on the car. it takes about 5-7 mins to warm up , hey Na_ how much did it cost you to replace that core .

i found a pretty nice all aluminum one on ebay for $75 shipped. took about 45 minutes to install (with 10 minutes of smoke breaks). look into replaceing the thermostat. thats the first thing you always check, besides leaks. cuz leaks are easy to check for, newspaper
