2005 Jeep Liberty 3.7L overheating


it's overheating, for sure,
is coolant levels dropping? cold checked at rad cap?
"pulled over and found a hose to cool the radiator and hose near the thermostat,"
i can not understand this statement"above"
if it overheat only parked, check fan for full ops.
if overheats moving too, wont stay cool moving fast
then:
bad rad cap
bad thermostat , they have 7 year life says STANT. (and why)
belts slipping (to water pump)
rad cores blocked (IR thermo gun it) ask
water pump impellers rust 1/2 gone?

all this assumes no coolant loss, if you have loss, tell where.,
where it leans
ground
passengers toes (foot well)
engine oil pan? milky oil
if A/T TRANS, check it for milky too.

New water pump, but now s70 is overheating faster


Who did the job? If you did it it privately, possible you did not do the whole job. You have to bleed the system for air comes out of the cooling system, also check if the timing belt is correct fitted.And last check if the cooling fan is working.

2.5 turbo diesel overheating


you have to use the thermostat or the water never stops to cool off. the thermostat stops the flow of water cools it off the lets the cool water in the motor and then cools down the hot water and so on put in a new thermostat if it still does it you have a blown head gasket

98 dodge caravan overheating...heater works..checked fans they came on later but when I drove it after it cooled down and it overheated...check engine lite came on.


About the only things are the thermostat and the water pump.There could be something with the radiator but that is the rarest because the water shoots straight through.If it overheats fairly rapid,it's most likely the thermostat.Sometimes a water pump will let you go 20-30 miles before overheat.The thermostat is cheaper and easier if you're going to try it systematically.Overheat will probably cause the check engine light too.Good luck!

I KEEP GETTING ABUILD UP OF PRESSURE IN THE COOLING SYSTEM ON MY CBR 1000FH


hi,might be able to help,i dont want to be the bearer of bad tidings but generally the only thing that will do that is the exhaust gasses getting into the cooling system,which will then pressurize the system and blow the water out of the overflow bottle,you may find that the head gasket on your bike has failed,i would recommend getting it checked over fairly quickly because if you dont 1 of 2 things will happen,1 all of the water will get blown out when you least need it and the engine will overheat(this normally happens miles from anywhere in the dark and it is raining)or the engine will start to cough splutter and die as water in the cylinders doesnt burn nearly as well as petrol,this will also happen miles from anywhere in the dark and the rain,hope this helps...cheers ian
