Ok I Got A Brand New OEM Thermostat From Honda. And I Replaced It Last Week. And I Replaced The Fan Switch Even Tho It Was Working. And Today It Started Doing The Same **** Again. Still Over Heating. Now What I Don't Get Is If I Hold The Motor At 4k. The Thermostat Gauge Flyies Down Back To Normal. Could It Be That The WaterPump Is Going Bad???? And BTW The WaterPump Does Not Leak AnyThing...

 

SomeOne Out There????

 

i had the same problem turns out i had a bad fan motor relay, i recommend this video it has step by step instructions about what could be causing an overheat issue

But The Thing Is That The Fan Stays Running But The Car Is Still Over Heating.

 

hmmm it could be a blown head gasket let your car cool down and check your coolant to see if theres oil in it it would have that glazed look like if when theres oil in water or a brownish color

 

Yup I Have Checked That To. No Smoke Or No Mixing Oil With Coolant Or Nothing.

 

damn last ting i can think of is to check the the front of the radiator for anything that could be blocking it

 

Nothing There LMAO. It's Crazy Because If I'am Driving Normal On The HighWay It Starts Over Heating. But If I DownShift On The HighWay It Goes Back To Normal.

 

Replace the radiator.

 

WRD

 

i think your water pump is going bad!! if it was the radiator the engine rpms wouldnt matter

 

You Have A Very Good Point!!!!

 

Fixed The Promblem This Past Saturday Guys.

 

Ok what was it?????

There is no point to post a problem and not say what it is..........this forum is to help others with the same problem.

 

I Did Write What Was The Promblem. But I Guess My Phone Did Not Post Everything I Guess By Looking At It.

 

Well Here Is The Rest Of The Post That Did Not Show Up.

I Did The WaterPump. And It's Running MINT Now. But What I Don't Get Is That The Waterpump Did Not Leak. And The Metal Fins Were Fine.

 

That is interesting, makes my worry about mine now since it is old.

When your car got hot did it do it running or at idle?

 

In for the answer also! Im having overheating problems only after 10-15 minutes on highway. Im thinkin it might be waterpump also :O

 

The Car Did It Both Ways. Idle And Running.

 

Have You Checked All The Other Little Things??? Fan Switch Ect Ect????

 

sounds like an air bubble.

 

Yes fan switch, thermostat, radiator cap, bled coolant system... Basically everything I can think of except the waterpump :/ I made a thread yesterday but no one has really replied to it.

Sorry to threadjack, but here is the link to my thread incase anyone can help.
