Will it harm or damage my car if i remove my thermostat and have it free flowing?

 

no, but your car is never going to reach operating temperature, which means it will run rich and you will get poor gas mileage. It's there for a reason. Will it damage your car if you took out the radiator? how about removing a door?

 

Several good reasons for not removing the thermostat:

1) Fuel consumption will increase. MPG may drop 40-50% depending on driving habits.

2) Engine will never reach "closed loop" fuel control where O2 sensor measures fuel-O2 mix and adjusts for optimum fuel efficiency.

3) Because of 2) you won't pass any state emissions test.

4) Catalytic converter may be damaged by excess fuel in exhaust and be damaged.

5) Fuel will contaminate oil, reduce lubricity, leading to poor lubrication and accelerated engine wears.

6) Colder engine temps lead to reduced piston/cylinder tolerances and increased wear.

7) You won't be able to get warm heater flow in cold conditions.

I can't think of a good reason to remove your thermostat.

good luck

 

Thanks TexasHonda!

Just trying to find out why my car is over heating. Remove the t-stat and still over heating, so i put in back in. Next i plan on replacing the temp sensor.

What do you think TexasHonda or any other fellow members?

 

Are you losing coolant? Does the reservoir overflow at any time? Are you sure both cooling fans run when engine temp is high?

More info needed to help.

good luck

 

Yes a little bit coolant lost[small hair line crack on top of raidator] reservoir fills up, but don't know if sprew out and both fans come on when temp is high, but seem like a little delay not sure how offten it should come on?

I'v also tried bleeding the system but no luck their

 

Oh added note my heater core is looped and ac doesn't work due to burned out clutch.
Heat core been that way since i owned the car.

Thanks again all!

 

A crack in radiator prevents system from pressurizing. This leads to coolant boiling and loss to reservoir. New radiator should fix your problem.

good luck

 

Thanks TexasHonda!

What the best place to get a new radiator other than Stealership. [I have the feeling you're going to say stealership]

 

Fleabay will have a to of aftermarket radiators. Some of them will be plug and play! Use only Honda coolant.

 

Thanks Mandy!

I think that's were the last owner went wrong at, they look like they used the green stuff 50/50 mix. Is Honda coolant blue lookin

 

^ Yes, and it's a nice colour.

~Cheers~

 

Just for everyone's information, i've seen a couple cars overheat worse when the theromstat was removed. The stat slows the water as it travels through the system. if the water is moving too quickly, it wont have time to be cooled by the radiator, and wont have time to cool the engine.
I dont see it happen very often, but it does happen.

 

Well shit. I'm running Green 50/50 .... Looks like I'm going to have to go get it flushed. :/

 

I removed my T-stat in August 09...no problems so far...average 19 mpg

 

 

Yeah i'm thinking it more my water pump than the radiator. I put some stop leak in it to see if that would help, nope not at all. I'm gonna still replace the radiator in the process. i just hope its not the head gaskit, if so i might just sell or trade the TL.

 

Don't put that crap in there. It will clog up heater core and radiator and replacing heater core isn't fun on these cars..

 

My heater core is already looped [disconnected] been that way since i had the car. I also plan on replacing the radiator.

 

Well got the TL back running All it needed was a new radiator. Running cool again.

Thanks to all!
