i need to know what makes my 94 sunbird get hot and stay hot....?

Answer 1

possibly no coolant, or broken water pump, stuck thermostat, clogged radiator, cooling fan not working, relay for cooling fan not kicking on when needed, electric thermostat not sending signal when needed, cracked block causing coolant to go into engine. I would check coolant first and check for leaks. If low fill up with water to find leak if any. unless your confident with tools check the thermostat

Answer 2

Check the thermostat, and water pump. The easiest way to do that is to find the lower radiator hose, while the car is still cold. Start the engine and carefully squeeze the hose and release it. did you feel a surge of water go through it? If yes than the water pump is probably okay. When you car overheats, is the radiator hot or cold. If it's cold, then the thermostat is bad. If the entire system is hot, you need to check if the cooling fan comes on. This is controlled by a sensor that sends a signal to the computer and is a little complicated to explain. Another problem could be the radiator cap is not pressurized enough and allowing coolant to boil away. In short, there are a lot of issues. Don't drive without the thermostat either. Fuel economy and emissions will suffer as the car has to run in an open loop mode.

Answer 3

Take this vehicle to a radiator shop formerly some thing rather is going incorrect. seems such as you desire an excellent kind of issues examined. First is the thermostat, a thermostat while that's undesirable won't open or won't open all the way next is the radiator, if the fins on the radiator are loose the radiator will over strengthen (radiators are made to strengthen to a undeniable quantity) and this might reason the vehicle to over warmth, a cloged radiator or a cloged heater middle could additionally reason a vehicle to over warmth or make the temperature upward thrust very quickly and variety. A radiator shop can attempt the cooling device (thermostat, radiator, rad cap, heater middle and the top gaskets with a tension tester) The mechanic that put in yet another fan on the vehicle did not assist you.... All he did is what's called a rapid fix, and in case you reside have been it snows you're able to have difficulty... in case you have the two.8 or 4.3 motor (6 cyclinder) in this vehicle i might guess that's a head gasket leaking or a clog interior the device. those engines have been primary for cloging problems if the device wasn't periodicly serviced... What you're able to do is circulate to the interior of sight aspects shop and purchase a clean thermostat and a flush kit for decrease than $20 greenbacks in case you're able to do slightly artwork your self. merely shop on with the guidelines on the flush kit and run water via the device with a backyard hose.. My kin owned a radiator shop for years and that i've got seen many cases while you're actually not getting good warmth that the heater middle is cloged and the temp will upward thrust, the vehicle will over warmth and the temp gage will variety..

Answer 4

I'm going to assume that you're talking about the Engine coolant indicated by the water temperature gauge.
This could be caused by:
A sticking thermostat
Low coolant (antifeeze) level
(also check for cracked and leaking hoses and gaskets which would cause a leak )
Improperly filled coolant--- Sometimes an air pocket develops if antifreeze was not filled properly. You might have almost enough antifreeze, but the gauge is not indicating correctly.
Bad water pump.
Faulty fan or fan sensor switch.
Take it to a repair shop.

Answer 5

If it starts to run hot when you are idling or at very low speeds (traffic) you have an AIR circulation problem, such as bad cooling fan, in most cases.

If it runs hot only on the highway, you have a water (coolant) circulation problem, such as clogged radiator.

EXCEPTION: a bad thermostat will cause overheating at low speeds.

Answer 6

Check your coolant level and your radiator fan. If it's low, find your leak. If your fan isn't running, just hotwire it to the ignition. Good luck. Oh, you may also have a stuck thermostat.

Answer 7

First thing I would check out is the Thermastat if that has failed in the closed position then you will constently be over heating, if that is good then check your electric fans make sure they are opperational and then I would check the water pump.

Answer 8

a bad water pump could also cause overheating, and check your hoses and clamps for leaks.

Answer 9

maybe you need to have it check out, or it may need water but I would have it check out

Answer 10

check your thermostat our your radiator.
