Corvette troubleshooting hey i have a problem driving me nuts, please help. I changed my waterpump and thermastat on 2000 c5 corvette 5.7 at first it ran good temp at dead center then it started creeping to overheating with bubbles in the rad cap. I took the thermastat out boiled it it only opened a 1/4 inch if that and it took 3 min to do that boiling water. now i put another thermastat in the car and i have more air bubbles and creeping hot. ive been told i have to bleed the system. i tried to remove heater hoses and nothing but hot air a minimum cooland, i didnt even have heat. after i removed both hoses from the side of the water pump one to res, other to heater core are ran dead center and i have heat. is there another way to bleed this car i keep having this creeping hot problem not happy.

If no air in the system from internal heater or other places
new thermostat and radiator cap
good firm coolant hoses

old school air bleed
you fill coolant system with motor running
heater on in the car and thermostat open

burp the hoses until bubbles are no more

if still no better
what about these possibles
faulty coolant temp sender
head gasket failed
clogged radiator
cooling fans not spinning fast enough
or not coming on soon enough

SOURCE: engine overheats when heater pipes connected

I think you could be right about there being air trapped in the system.
Or the heater core(radiator) is plugged.
Either way you need a pressurized radiator coolant pump to put the coolant in without air being trapped.
Although,i have seen it done by jacking the vehicle up high enough that the radiator was now higher than the heater core level, and then the coolant was put in.
But this is dangerous to try.

the thermostat should be closed when you take it out, therefore the thermostat is bad. It does not closed.

SOURCE: I have a 98 dodge 1500 5.9 with 180k.Changed the

your sure you installed thermostat correctly and no leaks around it ...are both top and bottom hoses hot going into and out of the heater-core and all fluid temps are at specified levels ...
you may also have an air bubble which when back-flushing may occur was the vehicle getting heat prior to reinstalling another thermostat / and while fluid was replaced into the radiator circulation /flow of exchange from the motorto the radiator are presenty working no vacuum lines are dry-rotted causing a vacuum leak ..hmmm you can hear the heater flaps open and change from the dash defrost to floor to vents etc ok that sounds like its working but check with the cap off to the radiator for proper fluid levels and that the fluid is exchanging and both the top and botto hose into and out the firewall are hot if the top is hot and the bottom one is coldyou may still have a lot of sediment /gunk in the core itself and reflushing the core is required and remember not to use full force when doing so or you risk rupture to the unit /core with the motor off remove the 2 hoses face the bottom or top on towards the catch pan because its illegal to disburse it onto the ground and whether your back flushing it or just running the water through you will also dislodge the air bubble as it fills with water after your sure the above is all looked into check to ensure the flow of fluid is present ...this is my starting point on your issue ...

Wont start when hot


If you recently had a waterpump replaced or leaking, i would say its the opti spark distributor. Main problem with the LT1 engines the water leaks all over distributor that sits behind pump causing the start no start up. When ever you change the waterpump always include the opti spark and wired connector.

I wanna know how to change waterpump


Remove drive belt. Remove all coolant, remove hoses to water pump, Remove all screws from water pump, remove gasket from hard surface, use permatex gasket sealer on both sides of waterpump gasket and apply to engine side, then waterpump, hold water pump in place until all water pump nuts screws are installed, use torque wrench, no more the 10 ft lbs. The rest is the reverse of uninstallation.

The car was running fine and suddenly made a loud noise like water gurgeling all warning lights about water temp came on is it the thermastat


Sorry, not the thermostat. Check the coolant level and refill and locate the leak. I suspect the waterpump, make sure the belt is turning the waterpump. Do not drive an overheating engine.

Water pump chang on mitsubishi Galant 2.5 V6


Waterpump replacement requires removal and replacement of your timing belt. Because of this it is not your typical do it yourself repair. Engine timing is critical, and not having your belt set correctly can lead to catastrophic engine damage.

You can purchase a service manual at your local parts store to get an idea of what is involved, however this being an interference engine you should leave this job to a professional if you are uncertain enough about your abilities that you need to ask for help on it. The cost to replace the waterpump is far far less than the cost to repair a engine that had an incorrectly set timing belt.
