no ive never bleed the system with the valve but i did fill the motor/radiator when it had the front of the car lifted as high as i could. and it only fluctuates rpms when about 30seconds when its cold and ruffly 30seconds later it goes away.


i guess ill drain the system monday and refill it.

 

I overlooked the bit about the motor being new. You're right, there should be almost nothing left over from the previous fill, unless you installed it carefully so it didn't drain out.

The amount you DID put in... how does it compare against the spec amount your car is supposed to take? It's pretty common for a drain/fill to be only 3/4 of the total. But when you remove/install the engine it usually can ALL drain out.

 

I filled a car with 100% anti-freeze because I didn't know you are supposed to dilute it. It over-heated and ruined the radiator, thermostat and hoses.

 

Best way to get the proper mixture in is to flush it and refill with plain water several times until you're sure that it is all plain water. Then use the radiator drain to get most of the water out. Look up the system capacity and add half that much pure concentrated antifreeze. Top up with plain water. You now know there will be exactly 50% antifreeze in there even though you didn't necessarily drain all the water out.

 

One other thing; if it is in fact pure antifreeze, it will eat your hoses and anything else that's rubber, like gaskets. Not right away, but they will corrode much faster than usual. Just drain and refill with 50/50, or maybe a little lower ratio if it was pure antifreeze.

 

well havent had time to get new fluid yet from dealership because i forgot my wallet today at home. and all that ice on the roads i dont want to risk making a long drive to dealership. so ill pick some up tomorow.

 

brokenarmboy: ok your gauge is a placebo hence it is always at one third so that is not a good gauge of temp you run antifreeze only to negate coroson and provide a little lubrication. Do not run pure antifreez you will only overheat your car (do not rely on the gauge) you need to run the mix and just replace it its easy and cheep insurance


On the do not rely on your dash gauge, I installed a mechanical water gauge in my old civic sedan (98' DX) because I had a su****ion that the gauge in the dash was just a placebo as well. While the dash gauge would never rise above half (unless somethins was terribly wrong, like not enough coolant after I installed the mech.) the temperature on my installed gauge would fluctuate between 140 and 220 depending on conditions. Throw some water (DISTILLED WATER! keep the deposits down) in that coolant.
