we have a chevrolet lumina sedan,the water is not going through the engine to cool it we have already changed?

Question

the thermostat & sensors . we only drove for about ten mins the other day & it was on full overheat (past 260)...we are also having transmission problems (dragging & surging).we dont want to give up on it yet I love chevy's.it is a 1995 & had a new engine in when we bought it

Answer 1

I agree with RON B it sounds like the water pump, best way to check on your own is right after you start the engine open the hood and have someone take a firm hold on the upper coolant hose or radiator hose as some call it. after the engine warms up and the thermostat opens you will feel a slight pressure in that hose from the water pump circulating the water, if you don't then it has to be the pump.

Answer 2

If your car has a V-6 engine, you probably have air in the cooling system. These cars have two air bleed screws in the cooling system. One will be on the thermostat housing and the other on the bypass pipe, located above the water pump. To bleed the air, fill the system as much as possible, then open these screws one at a time and keep adding coolant to the radiator until you get no bubbles from these bleeders. Install the radiator cap and let the car idle while watching the temperature gauge. If it gets hot, slowly crack open the bleed screws and see if you get more air. You may have to crack them several times to get all the air out. Sometimes you will even have to allow the car to cool completely and do the process again. Keep at it and you will get the air out.

Answer 3

Small airplane have air cooled engines because of the fact they are lighter and much less complicated then water cooled engines. there is despite the fact that a diesel engine it incredibly is obtainable that does have water cooling. unsure why it is water cooled different then its makes for greater constructive engine temperature administration. the main engine cooling required is at low altitudes and extreme potential placing while commencing up and mountaineering to altitude so the chilly of extreme altitudes isn't available for cooling.

Answer 4

SOUNDS LIKE A WATER PUMP PROBLEM OR A BLOWN HEAD GASKET IS THE RADIATOR STOPPED UP HAVE IT RODDED OUT AND CLEANED. CHECK RADIATOR AFTER ENGINE TEMP IS HOT SEE IF IT IS HOT ALL OVER OR JUST ON ONE CORNER ,CHECK ALL THE WAY ACROSS RADIATOR DID THE TRANS ACT UP BEFORE OR AFTER PROBLEM IF IT WAS NOT ACTING UP WHEN IT WAS RUNNING AT CORRECT TEMP THEN IT MAY NOT BE BAD JUST GETTING TO HOT WITH ENGINE IF SO AFTER YOU FIX PROBLEM CHANGE FILTER AND FLUID IF NOT PUT IN A NEW TRANNIE

Answer 5

Replace the water pump. It's rare but I have seen the pump impeller come loose on the pump shaft and not circulate the water.

Answer 6

water pump would be something to look at.

lets break it down for you...

the water cooling system goes like this.
1. radiator.
2. thermostat
3. water pump
4. heater core.

water must flow, you do have 2 radiator and heater hoses.

whats blocking the water or preventing it to flow??

hummmm......water pump.....hummm, don't know

maybe????

as far as transmission, take it to a shop!!

rat.

Answer 7

sounds like the water pump is shot, not difficult to replace. If it has a serp, then replace at the same time.

Answer 8

head gasket could have a problem
this is costly do not drive till you have a mechanic check this one

Answer 9

YOU SHOULD HAVE SOMEONE THAT KNOWS HOW TO BLEED OUT THE COOLING SYSTEM, SOUNDS LIKE THERE IS AIR TRAPPED IN IT.

Answer 10

it seems everyone forgot to mention the radiator it could be clogged
