jdm21

Hello I have a 96 ek hatch with a 99-00 front end and i have a problem. For some weird reason when the car idles for about 5min it starts overheating then when i start driving it goes back to normal temperature its a pretty stock d16y7 and i have no idea wat the problem is. Is my engine bad? So the main problem is that it overheats when idleing. and sometimes the check engine light comes on and when i idle with the check engine light on it doesnt overheat. so what do u guys think the problem is?? also when i floor the gas i get this nasty burning smell coming from the engine.. oil is good and everything.. ur help is very appreciated thanks..

..because theres no air flowing thru the radiator when your not driving so...ck your fan see if its working....while your idling (when your temperature pass middle)

bleed yur radiator, and check the cap and report back to us

Check your oil for possible blown headgasket. Since you mentioned a bad smell. Make sure there is no Coolant in your oil. If its normal it should just look like oil, vs a whitish brown color of coolant and oil mixed.

When was the last time you changed your thermostat? If you dont recall changing it ever, change it with a new gasket. Does your fan come on? Jump the harness at the thermostat housing with a paper clip to see if it even works (unplug from the fan switch located on the thermostat housing and stick the paper clip making it into a U shape, and stick each end in the plug)

But start off by changing the thermostat if that hasnt been done, if thats not the problem try bleeding the radiator for possible air in the system and replace fan switch if the fan works but doesnt come on after idling for atleast 10 min or longer.

your thermostat isnt working correctly. the reason its overheating when your ideling is because your thermostat isnt allowing coolent to flow thought the block so its not cooling down your engine so its over heating. when you drive the wind from going though the grill cools the engine down enough. when you check engine light go's on, it tells the ecu to bypass the thermostat so it opens it up and your car cools and runs fine. so change your thermostat and if the problem still persists, check the block temp sensors. i think the reason your smelling something is because the coolent is boiling in the block. hope that helps you

^^^wtf???? Hope you aint serious.

Wow.

Mrmatt3465

Does your fan kick on? If not wire it straight to 12v. If it comes on then its your ECT

Are you mad ******* me or agreeing with me?

Cuz in all my Honda knowledge I have never heard of a CEL coming on to bypass a t-stat! As if the T-stat was electrical.....LoL

x2 lol
but heres something when is the last time u changed the radiator fluid? its supposed to be changed every two years. just droppin some info u may or may not have known. gl

JohnnyWash1

I'm agreeing with you.

lhd dc2

bypass a tstat. lol

lexluther

I agree, i never heard of a thermostat being 'bypassed' by the ECU! Interesting! ;0

I've had this same problem, turns out the headgasket was blown.

I have a similar problem and was a clogged radiator... i spent $30 only and run likes new again!

Good Luck.!

If you haven't fixed the problem yet, I'm pretty sure it's a stuck open thermostat.

just searched through thread and this problem exactly happening to my b16a. I've flushed the radiator couple times, check the fan is working and thermostat is working i supposed since it run my fan when overheat. BUT still the the engine's overheating and i realised that the coolant reservoir water level was much more that the maximum level.

what could be my problem?

lceah

I agree with: thermostat, fan motor, radiator, cap, and check hoses...

OP, when you mentioned the smell when you gas it, I thought maybe you are running rich...

carcious

Wouldn't it be stuck closed? Because I had a CRX with an open thermostat and the thing took forever to warm up. Not the other way around.

But yeah check your thermostat and radiator. Good luck.

JohnnyWash1

Thermostats are designed to fail in the open position.

sorry dude (jdm21) if i jacked your thread since im having almost the same problem wouldnt want to create another new list of threads. anyways, reflush my rad earlier and left it on idle for ten mins. Question is should my fan kick on during the idling because it didnt? My temp level as below during the 10 mins.

sp00ledbseries

Holy ****ing thread hijack but ya thats normal operating temp

chrissleame

yeah i know but jdm21 should be compromising i hope ;p

anyways, had another flush and realised there's like awesome loads of bubbles...what does this means?

lceah

^that is because of bad head gasket, I believe...
