Hey everyone,
95 Honda civic ex 1.6 liter V-tech coupe
I got a new Radiator, New head gasket, new thermo, New timing belt, new water pump and new NGK Spark plugs. The temperature is still going up when I'm idle stopping at a light. I have to turn on the heater just to let engine cool off. I don't know what else to do. Any information will be helpful. ??could it be a thermo switch??

 

whats your setup? it could be the switch

and its not vtech...those are phones. its VTEC
(prepare to get flamed)

 

hey,
thanks for your answer. Everything is Stock and I still don't know where the switch is.

 

"thermoswitch"
the switch which looks like a sensor, attached to the water neck/thermostat housing and it is what determines when your fan will come on to aid cooling of the radiator/coolant.

try that!

 

How much does it cost to replace the thermo switch?
It is simple to replace yourself?
If I take it to the shop, how much should I expect to pay?
I need pictures of how a thermo swith looks like and instructions on how to replace it. Any help??????

 

Have you flushed your coolant?

 

Is your fan coming on at all?

 

no, but there is new coolant in the radiator that just replaced. Hey how do i become a member. I'm a trial user and this is my fifth posting in other words my last. So any info from anybody and everybody would be nice. Must fix car today. I'm going on a trip tomorrow and need the car. Please give me info on how to fix problem and how to become a member of honda-tech. Thank you very much!

 

trial user means you can't post 5 or more messages in a 24 hour period and you can't post in some forums

 

take a paperclip and jump the fan switch so the fan stays on the whole time while the car is running. Should prevent the car from overheating.

 

check your radiator fan motor,fuse and relay.is the fan on at idle andif all that is ok it may be a thermo switch but it would overheat at any speed

 

I need instructions on how to replace the thermo switch
Can anyone tell me how to replace the thermo switch?
Oh and can anyone tell me how to become a member of honda-tech?
I need all the info possible.

 

as far as becomming a member...good things come to those that wait...it take a few days...

replacing the thermoswitch is a breeze...unlug it,get a wrench, and unscrew the old one...reverse the process to reinstall the new one.

location should be on the passenger side of the head, usually very close to the distributor.

 

oh, and one other thing.

we had a simular problem on a friends car. we went thru 2 thermostats from Autozone on a friends car, before trying an OEM one...3 time was the charm. If you arent using OEM, try one from the Honda dealer....its cheaper than a switch, and if it is the problem, then you didnt waste money on the switch.

 

how can i tell if it is the thermo switch is not working when i take it out??
can it be tested?
I mean i don't want to waste money on two or three thermo's when the problem might be the thermo switch.
What if the thermo was working fine in the first place.
please tell me signs of what might show the defectiveness of the thermo switch.

 

usually if the switch breaks, it will be either stuck open (which isn't that bad besides it takes a zillion years for your car to warm up) or stuck closed which seems like the case for you if it is your switch because your car is overheating.
I replaced mine with one from autozone and haven't had a problem with it, since i'm ordered a spoon, but just haven't gotten off my *** to put it in or anything else that is sitting in my basement =\

 

wassup fellow hmongbrotha! same problem with some dude i just helped in a recent thred. Have you checked your fan to see if its still intackt with the fan motor bolt. In some cases the nut that holds the fan onto the fan motor gets loose or falls off leaving the fan useless while the motor spins. Check it out and see if thats the problem. good luck bro

 

Open your radiator cap and turn on your engine. Let your car idle with the cap open until all the bubbles come out. That should solve the problem.

 

Bleed the radiator. There may be air in it from replacing the t-stat.

 

Some good advice given above. I'm just curious, did you have a shop/mechanic do all the service you mentioned? If so, they should've been able to figure out the problem.. If you did all the work yourself, props..

 

how do u bleed the radiator?
How long do i let the car run idle without the cap on?
Is a thermostat the same thing as a thermo switch?

 

thermostat and thermoswitch are 2 different things.
the thermostat tells the car when to cool the motor and
the thermoswitch turns on the radiator fan to prevent the
coolant from getting too hot.

 

Ive tried damn near everything to stop my c1 from running hot..i just cant figure it out...fans jumped, radiator flushed, different temp thermo's, took the thermo out, the head gasket is good

 

hey everyone, i already replaced the thermoswitch and everything is going okay now. Thanks you all for the advice and i hope one day i can offer my advice to you guys. Thanks lots!!!!!
