Question about Cars & Trucks
I have a 95 impala i changed my radiator,water pump & hoses i changed everything on the car to stop making it run hot...but now it doesn't run hot but the water in my reservoir tank is keep boiling & my water hose never get hard
Sounds like your coolant is not circulating for some reason. Typically it's the thermostat that blocks the flow. If turning on the heater inside helps the car not overheat then your coolant is not flowing. Other issues can be a water pump that isn't working, air in the system that has not been bleed out, engine head broken (blocked).

I have had this problem with my 98 aurora and have replaced all the same components. Temp gauge routinely shows 200 on highway (Fine) but in the city in stop and go will get to around 245. I installed a switch to manually turn on the cooling fans by connecting the ground to pin 86 in the relay for the fan(s). Otherwise the fans will not turn on to 245. This fix works but would like to know an actual solution.

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

SOURCE: Water not staying in Radiator
yes, not having an overflow reservoir for your radiator will cause you to lose water. As your engine warms up the water expands and creates pressure in the cooling system. When the pressure reaches a certain point(usually about 15 psi.) the radiator releives the pressure by releasing water into the overflow tank. When the engine cools back down the water shrinks pulling water back into the radiator from the overflow. If there is no overflow, the everytime the engine warms up on a drive water will be lost and not recovered on cooldown.

I had the same problem, whole new radiator, new hoses, new thermostat, and still overheating. What the problem was for me...bad radiator cap...all that money and a $20 fix...try it?

Testimonial: "YES... I HAD THIS DONE ALREADY... BUT IT HAPPENED EXACTLY AS YOU SAID... THANKS ANYWAY!!!"
the water pump and thermostat should have solved it. an air pocket can cause that but usually not to that degree.
don't get one of those cheap *** plastic impeller water pump for sissies. Get the metal impeller one. get a cool running thermostat and drill two 3/16" holes in it 180 degreess from each other. you may have installed the t-stat backwards.
