Car Forum / Honda Cars / July 2005Heater takes a while to get hot.
Hi All, Now in the colder months in Australia I have noticed that my 1995, 1.5 litre, 4 Door, EG, Honda Civic heater takes quite a while to get hot. Is this normal, and is there anything I can do to help the heater warm up sooner. I have notice that the temp gauge wont move from cold until at least 10mins worth of driving (not that I dont mind the car running cool but I keep freezing in the morning) Regards, Michael.

My 1991 1.5 Civic takes aboiut that time to start blowing hot air. On rally cold, below 20F (~-10C) I let the car idle for 5 miniutes or so. More of a ssafety issue, I am not willing to drive with frost on the inside of the windshield. I change the oil more freqeuently at 2/3 the suggested milage.

SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ > Replace the thermostat. Yeap. I've had once the same symptoms and the reason was that the thermostat was stuck open. Rudy Well I am just going to change it now anyway and see if it makes a difference and I will keep you all posted once I have installed the new part. I just need to get some time now to go down to my dealer and get the parts to do it. Yesterday I changed the thermostat and the car is now running back at its normal opperating temp. The faulty one was stuck open as a few people suggested in this thread. Thanks for the help, Michael. > Yesterday I changed the thermostat and the car is now running back at > its normal opperating temp. > The faulty one was stuck open as a few people suggested in this > thread. > Thanks for the help, I wish all car problems were as easy to diagnose as that one. ;-) Rudy > Yesterday I changed the thermostat and the car is now running back at > its normal opperating temp. > The faulty one was stuck open as a few people suggested in this thread. You're lucky yours was stuck open, Michael. Mine stuck closed after a fillup at 1 a.m. on Saturday night ~120 miles from home and ~30 miles from my destination, and the temp gauge shot right up into the red. Hope I noticed it in time--my engine hasn't seized yet, so maybe... That's close to the worst time I can think of for a thermostat to get stuck closed... I was lucky it was cool out (65 F), and that the heater can double as a mini-radiator in a pinch. Cranked the heat (defroster, so I didn't fry my legs off) up to full blast and reduced acceleration to reduce heat generation, and I made it to my destination with temps below redline. Had hoped I could limp home and do it myself with OEM and a coolant flush at the same time, but steep uphills and 85 F temps killed that idea right fast. Luckily I found a mechanic along the way who was willing to change it out at 5:30 p.m.--one of those guys who runs his own place and closes when he's ready. Nice to run across guys like that. Frank Scigulinsky at Center City Muffler & Service in Westfield, MA. I also appreciated the fact that he didn't bleed the system cuz he was concerned that he not crack the water outlet cover at that late hour. Guess the bleeder was in pretty tight. I gotta change the coolant anyhow. > Hi All, > Now in the colder months in Australia I have noticed that my 1995, 1.5 [quoted text clipped - 5 lines] > Regards, > Michael. ------------------- When it's -40 F, I start the Honda, brush off the snow, and drive gently to the road, then to the secondary highway, then to the main highway. It's about three minutes to the main highway, and the heater is getting toasty and the guage is at the normal position. Make sure you don't put any tap water (Hondacide) in your Honda when you change the thermostat, and check the reservoir the day after you get the thermostat replaced. 'Curly' That is not directly related to your issue but my 91 Accord doesn't really seem to warm up in winter unless i'm doing city driving, on the highway the temp gauge stays at cold and the air inside is coming out kinda cold too, even when the heater is at max. Of course it's not a problem when you live in Texas but I got kinda chilly on my last 4000 miles winter round trip to Canada! When I'm in real winter weather, everything is normal when i'm in heavy traffic or in the city, a lot of red lights, makes the temp gauge raise a little with nice warm air coming out, but as soon as I pick up some speed it falls back to "Cold" and the air coming in the cabin is not warm at all. I am curious what causes that... Even if I will probably not fix it. RAT > Hi All, > Now in the colder months in Australia I have noticed that my 1995, 1.5 [quoted text clipped - 5 lines] > Regards, > Michael. The place to start is replacing the thermostat. It is cheap and easy and it would definitely explain the cold running. Running the engine too cold all the time isn't good. >That is not directly related to your issue but my 91 Accord doesn't really >seem to warm up in winter unless i'm doing city driving, on the highway the [quoted text clipped - 18 lines] >> Regards, >> Michael. > That is not directly related to your issue but my 91 Accord doesn't > really seem to warm up in winter unless i'm doing city driving, on the [quoted text clipped - 7 lines] > "Cold" and the air coming in the cabin is not warm at all.

SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ Thanks for the info ppl. I will most likely change the thermostat as it may be staying slightly open. I got a price today for around $60AU including the gasket so it wont hurt the pocket to much.

The engine will run rich, which will wash oil off the cylinder walls and lead to increased piston ring wear and diluted lubricating oil, as well as reducing catalytic converter life. A bad thermostat is a very bad thing. The thermostat is a very simple and easy thing to replace when you're draining the coolant, which should be done every two years, even with "Long Life" coolant. And it's cheap. An OEM thermostat is less than $20. Having it replaced by a garage should be less than $100. Never use aftermarket thermostats. SignatureTeGGeR® The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ I never thouht a faulty thermostat could do so much damage. In my old car I use to pull it out in the summer to make the car run cooler. It has over 400,000km's and its still going strong. > I never thouht a faulty thermostat could do so much damage.
