i have a 94 cx i picked it up because it need rings, i replaced the rings the car runs great except that it takes a little bit to warm up. i have replaced the thermostat, didnt help, i have gone over all my coolant hoses and they are all hooked up right. when i got the car it had a radiator for an automatic, its bigger, but mines a manual i put cardboard in front of it which helped a little but it just takes to long to warm up. i think the fitv needs to be cleaned it has the smallest idle up and down, but as soon as i turn on the air or turn on lights it goes away. its gotta be bypassing the thermostat somewhere...but where any help would be great.

oh i dont know if it matters but i put a 16 valve head, intake and throttle body on as well

 

run it without the rad cap for 15 mins, if it's still too coool, replace the thermostat (again)

 

like how long is it taking to warm up?

 

ill drive to work 20 min away and it still isnt warmed up, i live in cincinnati and the temps have been in the 40's im worried that it will get worse as the temp decreases

 

bump i will take any ideas

 

when you get to where you are going....how high is the temp gauge?

 

I hear what you are saying, but an internal combustion engine can't "warm" up after 20mins?

How do you know the car is not warm?

Is the temp guage correct?

 

let the car sit in the garage (if you have one) for 20 min and see what happens...it might just be really cold outside that's y ur temp is still real low....my gsr takes a little bit to warm up if it's cold out side...the temp tends to drop just a little bit once i start driving if it's super cold could out side then comes back up....

 

when i get to were im going with any other honda ive had the car is warmed up all the way, this one is not its like 1/4 the way up the guage, also if you turn on the heat the guage will not go up infact the guage might even go down a little

 

after driving for a while and u turn on the heater is the air hot??? if it is u just might have a bad gauge or what do u call it ( the piece that's on the head ) i wanna say thermometer...

 

my guage works fine there is nothing wrong with it, my car warms up all the way but, it take forever, and once it gets all the way turning on the heat cools it off to much

 

CHANGE THE FERKIN' THERMOSTAT

 

i live in Columbia sc. it takes my car roughly ten minuets to heat up in 45 degree weather at idle. i drive a ls integra. as im driving in the cold weather after it is warmed up all the way. the gauge drops a little bit, like stand outside in the cold. then run. u will get colder because of the breeze you are getting. let your car warm up without driving and see how long it takes. if i don't let my car warm up and just drive off it takes it about 15 minutes to warm up to the right temp.

 

i have changed the thermostat i dont think thats the problem

 

that sounds about right...my car if i drove it with out letting it warm up it would take 30ish to warm up, with out turning the heat on.

 

Sounds like you might have air in the Cooling System or a Clogged Heater Core or Hose. Give a good Flush.

 

the motor has been in for a month now the water pump should have pushed those all by now right?

 

bump for any new ideas

 

Does the idle go down to normal? Ignore the heat gauge for a minute, consider it warmed up when it idles low, is it still an issue?

I'm just going at it from the angle I know not all gauges read the same temperatures at the same spot on the gauge... Iono could be a thermostat too.

 

Remember the time when I hade same exact problem on 94 Toy Tercel. It acted like it's taking forever to warm up. Tried cardboard trick but then it started overheating on the long runs on the highway. Silly me tired everything along with changing thermostat twice. And as soon as i picked up different cluster from junky everything went back to normal. And no i didnt put my finghaz to the cluster before the problem occured. It was just some natural inefficiency of temp gauge .

Borrow a cluster from your buddy and make sure this is not your problem.

get a oem thermostat

 

I agree. your thermostat is dead.

here's a way to find out: when you're temp gauge shows that it's warm and you drive, does it drop to dead-cold again? once it does that, your car may go into fast-idle mode thinking that it's cold again.

how do your hoses feel after driving around for 20mins? are they hard or cold at all?

put in a brand new thermostat. you never specified if you changed the thermostat to a brand new one...don't put one in that you were told was good...just to be sure.

 

it does idle down after it reaches operating temperature. ive got two hatches so i might try sawping out the guage cluster, the fuel level moves a **** load around turns... it may be that

i have not put a brand new one in myself, i know the guy i got it from he wouldnt bullshit me. it is new, but i guess the new one could have taken a ****...**** i guess i need to stop bein a broke dick and spend the 5 bucks on my beater

 

i have same problem takes about 15 to 20 mins to get warm and sometimes while driving with the heat on with taking it easy on throtle it drops in temp until i apply my gas but now that i read this i will change the thermostat
