its either you did or didnt

Water Pump.

i ment to say ill probably change the thermaostat, ya there is some smoke when you push it hard of the light

 

ok what color of smoke, do it at ur house have someone stand in back of ur car, and have them tell u if its oil burning or sweet smelling, that would be ur antifreeze

 

i would agree with water pump or thermostat.

 

I'd try the thermostat first, since it's a cheap replacement.

 

Could be a few things

1. Air in the cooling system (not likely unless you recently had a cooling service)

2. Thermostat (go ahead and change it out its cheap and you prob need one anyway)

3. Waterpump

4. Clogged radiator (I experienced the same exact prob you were having and this fixed it for me)

5. Blown head gasket (check the color of the smoke coming out your tail pipe, if its white then you may have a problem, check your oil for water bubbles as well)

 

its a little bit of black smoke.....ill change the thrurmastat and se what happens... ill post the results.... thanks for the help

That's normal on any honda as old as yours especially if your running any kind of aftermarket programs on your ECU (black smoke=running rich(lots of fuel)). Check out your thermostat and radiator (I think you can have the system pressure tested).

 

if it gets that hot within just a few minutes, thats bad,

I'd go with head gasket if it's the stock engine. The non vtec SOHC used a composite head gasket which fails really easy.

 

ya i prssure tested it at tech.... i took it to my friends shop he will have it good to go by the monday
