If your water pump isn't leaking or making a lot of noise (when the bearings go it makes a lot of noise, and it will leak),don't change it. Check the radiator cap, it could be shot, and it's a cheap fix. Next step would be to flush out the system. If u haven't done it in a long time, there could be a problem w/ rust and sediment plugging up the radiator, not allowing the coolant/water to circulate properly, causing it to overheat. Let me know how it goes. countrycurt0

My 2001 pt cruiser limited over heated. It has already had a new radiator and both fans replaced with in the year. Should i now replace the water pump which is the original?


Overheating is caused by:
1. plugged radiator core
2. Wrong mix of water and coolant.
3. Low coolant level.
4. stuck thermostat
5. hoses collapsing.
6. Air lock in system
7. Bad fins on water pump.

No heat coming from the vents.


If it is a manual system--sounds like coolant low ie: air bubble in system. If it is ATC system, Check Codes, if no failure codes, coolant may be low--air bubble in system--most Durango's have air bleeders in system.

Dan how do I bleed 2004 Kia coolant car temp is good but sometime at idle heater starts to blow cool hit throttle gets great heat


I agree with your logic. Attached vid addresses bleeding. Sounds like at low rpms, not enough flow to transfer the heat. So bubble or maybe a partially obstructed core. There are a couple of vids on clearing a core... GOod luck, let us know if you figure it out.

Temperature gauge cold then back to normal


You have to make sure the thermostat is working properly and is the correct one. Idle the vehicle for about 20 minutes and then feel the upper radiator hose. It should be hot to the touch. Drive the vehicle and when the temp gauge falls to 'cold' stop and feel it again. If it is much cooler to the touch than before the thermostat is defective or wrong.

Cause no heat temp gauge red lined in


sounds like the thermostat is stuck shut..unless the head gasket is blown somewhere.. it will pump the antifreeze level down to form an air pocket.. this will cause overheating constantly check each cylinder for even compression..the lowest reading will most likely be the blown cylinder..

The high temp gauge will max out and then back to normal. Also the heat will not work then kick in all of a sudden.


Let me guess...When the temp gauge goes hot, the heater goes cold, and vice versa? Check your coolant level first in the radiator (when the engine is COLD) and also in the overflow reservoir. ONLY use a 50/50 mix of coolant and water, using the same COLOR coolant that is already in the radiator (if it's green, buy green, if it's orange/red, buy orange/red). Next thing to have checked/replaced is the thermostat which is inside the cooling system of the engine. Finally, and the most expensive, have the water pump checked/replaced.

I would put my money on low coolant level in the radiator. As the engine heats up, the coolant will "surge" through the system as the water pump tries to **** air through the system due to low coolant level. If the coolant isn't flowing, the heat can't escape the engine block and it starts to overheat.

My truck is over heating what is causing for geting over heating?


their could be several problems that cause over heating, now the most likely cause is that the thermostat has packed up and needs replacing that would be the first thing to get replaced.

how ever other causes could be:
coolant leak, this lets air in the coolant system and this causes it to over heat so have a good look for any leaks in the hoses, rad, water pump.
if the rad fan does not cut in when the temp gauge goes right up past 90 then this could be the cause of your problem you may need the fan switch replacing.
another problem could be with the water pump if this is leaking or the bearing gone then this can cause over heating

now worse case the problem could be head gasket failure but first rule out all the above as this is worse case scenario, most likely the thermostat needs replacing

Heat gauge shows hot , have to add antifreeze although no leak


Very common fault is head gaskets.  causing coolant consumption and bubbles in radiator.  Run vehicle, have a friend accelerate once or twice hard, while you smell exhaust for sweet smell of burning coolant.
