Any possible reasons why I'm losing coolant, and/but the resivior tank fills up? Any ideas? Thanks

 

are u over heating? check ur oil for a milky like substance.

 

if your losing coolant and you have no leaks then its getting into the cyl through the head gasket. Now most headgaskets leak alot but sometimes you can get a small leak that goes into the cylinder (also you can have a cracked sleeve but that would produce major pressure into you cooling system and you would be popping hoses or other nasty problems. I would do a cooling pressure test and also check your plugs and cylinders for lack of carbon.

 

Well i just dropped $940 bucks fixin that **** (new timing belt, water pump, a few seals and a couple other things) but my car's still overheating...WTF?! My mechanic did everything, like bleeding it and all, and it seems like if i rev hard, or high rpm's the **** goes up. Seriously, wtf

 

leaky radiator or radiator hose? bad or leaky thermostat?

 

he would see the coolant if it was leaking if things were "leaky".

Do an oil change and see what color the oil is when it comes out. If its milky your headgasket is gone and that explains where the coolant is going.

If it looks normal, that will rule out head gasket.

The resivoir tank fills up when your radiator over heats, increases pressure, and needs to displace the extra fluid due to the heat expansion. This indicates that perhaps your radiator is "going" or the fan might not be operating under normal perameters.

I would say start up your car, let it come to idle. See if the coolant/radiator fan turns on. If not, your fan is not drawing air into your radiator, to help cool the coolant. If it does turn on, than perhaps a sticky thermostat. This would cause the relay to not turn the fan on at the appropriate temperature causing it to overheat, which would force more coolant into the overflow resivoir.

Other than that I don't have many ideas.

good luck !

 

Take it back to that mechanic and tell him your not going to pay him a dime if he's just going to swap parts and pray it fixes your problem. I'm tired of hearing about these mechanics. Honda stealerships are the same way. Just swap parts out and pray. How about some actual diagnosis first ffs. I would say mechanic's troubleshooting skill in general has slackened for the simple reason that they rely on what computer's tell them, given the peramiters that have been entered.

How many miles where on your water pump and timing belt anyway?
Did your mechanic suggest you swap them out in attempts to repair your coolant loss? If so, he's already a moron. Make sure you get your old water pump and look at your timing belt. If theres nothing wrong with the two of them, than this shop just took you for a ride.

If possible get your old water pump from them and timing belt and post pictures of their condition. Spin the water pump shaft and listen for the bearing whinning. If theres no whinning and it spins freely without hearing any clunking noises chances are your water pump is fine.


Sorry about your luck dood. Shops are usually a rip off. Thats why they invented the DIY
