Need help car overheated

Hello,

My car overheated by one bar on the temp gauge while at a stop light. After a few seconds looking at the gauge the temp went down to normal. while driving home 'maybe 15 to 20 minutes' hit a few lights on the way, the temp stayed normal. When I arrived at home I went to pull in the car and while doing so the temp gauge went over 1 bar again. I shut off car, but i didn't hear the fan just before I shut it off so I turn the key to on and the fan came on 'after that I shut the car off'.

This morning I went out to see what's going on with the car. I checked the fluid level at it seem fine, the res was half full. I started the car up to let in warm up to normal running temp 'on the gauge' and felt the lower radiator hose the it was cool but the upper was pretty hot. I let it run for while thinking it might not be up to temp, but i got the same results. I went to pull in the car all the way into garage, since i rolled it half way out. After pulling it in I went to check the lower hose and it was finally semi hot not as hot as the upper hose. And I don't think the fan kicked on at all 'i didn't want to run it any longer'.

Can it be the thermostat is bad or the water pump?


any help would be great....

thanks

Re: Need help car overheated

yes it was. I forgot to mention when i checked the fluid level in the rad, I squeezed the hoses and had some bubbles came up. I just got back from an hour worth of driving on local streets with the heat on and it didn't over heat. I checked the oil level and it was low by 2 1/2 qts. I'll have to drive it around this evening with the heater off and see what happens 'maybe it was the air in system'? Would low oil level lead to alittle overheating, since there is an oil cooler where the oil filter screws on to; and could air be trapped in the system for several months with out having issues. I say that because I had the water pump worked on in the beginning of this past winter.


Thanks

Re: Need help car overheated

Considering it goes back down once you start moving, and only does it when the car's warmed up and sitting at stop lights, and the fans aren't coming on, then the problem's more than likely fan related.

Re: Need help car overheated

^exactly, i had the same problem, when the car sits, the heat from the engine sits, when the car is moving, the air coming through the engine bay carry's the heat away. change fan, not the ac fan. you can tell if its ac by turning the ac on and checking the fan that turns on ..on the spot, change ur broken fan and make sure to check the fuse for it

Re: Need help car overheated

replaces the thermostat
replaces the radiator cap
replaces the temp. sensor
replaces the old coolant
there's nothing wrong with ur fan and make sure u have to use Honda thermostat ..

Re: Need help car overheated

i agreed with lude zone..
i faced this problem before..
same like TS..
thermostat open late can cause add 1 bar at indicator..

if ur problem is like this..
bar increase when stop= check ur fan speed..ur fan working but maybe slow..add relay if needed.. why i say that,,when car stop..only fan WORKING To cooling ur water in RAD..but after car start moving..fresh air help to cool ur water in rad...

if ur temp bar increase bar and going to normal bar while car is moving,,
im very sure that was thermostat problem because open so late...

Re: Need help car overheated

I ran the car with the rad cap off and had a bunch of air bubbles come up. I haven't had this same issue again with the temp. Although, i did have oil cooler hose bust open, so I replaced those along with the heater hoses 'never replaced before'. while taken off the hose feeding the heater core from the engine I noticed some milky 'white' looking coolant. I think some oil is mixing with the coolant somewhere. Any takes on this?


Thanks for advice
