SOURCE: 1996 jeep grand cherokee blower works but no heat

Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

SOURCE: 1998 olds aurora water is

You may need a new water pump considering the age and if the pump has not been replaced in a while. Try to check also for leaks in the radiator hoses and under the engine. See if you can move or disconnect the radiator hose by hand. If you can, it may need refitting or if the hose is to hard for you to squeeze it may need replacing.

If the hose is ok, when putting in coolant squeeze the hose to get as much air out and observe the engine.

At cold start remove the radiator cap and observe the water while the car idles. If there are bubbles or white smoke from the exhaust. Then you may have a bad head gasket and you are loosing water from the head and it may be going to the exhaust or the cylinder.

New thermostat, fan switch , fan comes on, still overheats . Upper hose hot, same lower hose but both are hard feels like the water is not circulating . Bad water pump, or head gasket ?

Most likely pump. Head gasket will usually put hot gases into the cooling system and will appear as bubbles in the cooling fluid container. It may also feed lubrication oil into the coolant. The coolant pump is driven by fan belts. Make sure you are not missing any belts.

Heater hose hot one side cold on other

If it is hot on the engine side and cold on the radiator side then most probable the water pump is nonfunctional. The water is not circulating and hence remains hot on the engine end and cold on the radiator end. The water pump needs immediate attention as the engine may get harmed if not rectified.

I put on new water pump.Motor still gets red hot.could it be rad.

You need to make sure the coolant is circulating. Check to make sure the top and bottom hoses are hot and firm to the touch. If the bottom hose is not hot and firm the water isn't circulating which means the thermostat is stuck in the closed position. Also check to make sure the radiator isn't clogged or doesn't have to many crushed fins that prevents the air from properly cooling it.

Overheating: 1999 bmw 323i m series 2.5 ..Installed: new water pump , thermostat. radiator,new Water Reservoir, cap.. hose on top side hot , lower hose cold even when engine is water circulating at...

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.

The fan works and i changed the sensor

you need to first check that the water is circulating if not could be a water pump or thermostat problem also check for signs of oil in the water this could indicate a head gasket problem if your unsure this can be checked out using a special fluid

1989 Isuzu troop temp gauge goes straight to hot when key turned

there is a sending unit for the guage.but if it has been running a few minutes and gets hot you may need to check the thermostat or water pump.check the water pump by taking the radiator cap off.then start the vehicle,look into the radiator and see if any coolant is flowing or the cheapest fix first

Temp gauge goes from cold to hot.

You can remove the rad cap and run the engine ( do not remove cap when hot!! ) You should be able to see the coolant circulating in the rad. You can also remove a heater hose and hold upwards and start engine, if coolant flows out the pump is circulating. If all looks good at that point I would start to suspect a cylinder head gasket leak and / or cracked cylinder head. Hope this helps .. Good Luck

Daughters 1996 ford contour 4 cyl. died on the road.After sitting a while it started again then drove it home.It starts and runs good but after warm up it bubbles out the expansion tank, I replaced the cap...

dear sir,

the solution to your problem is simple. yes you say that it has a new water pump, but the reason that a vehicle bubbles out of the expansion tank is because the water pump is not circulating coolant, the coolant boils in the engine and bubbles out of the expansion tank. secondly the reason the fan never kicks in is because the temp sensor is not seeing the heated coolant because the water pump is not circulating the coolant through the cooling system. 3rd. the heater never gets hot because the water pump is not circulating coolant through the heater core in order for it to get hot and provide heat. and the temperature gauge never seems to go up because yup you guessed it, the water pump isnt circulating coolant in order for the engine temperature sensor to see hot coolant and thus send a signal to the engine temperature gauge as to the coolant temperature. i know you said it has a new water pump, but i have heard that this type of vehicle may come with a plastic fin pump. i would remove the pump and check the passages for foreign matter{ trash} in the passages as well as the condition of the new pump. also one last thing, the reason the vehicle died on the road in the first place was probably because it overheated. happy hunting and please post to see what you found. i am a mechanic by proffession.
