You may have an air pocket in your system which some times happens.  One way to get rid of it is to take the upper hose off on the engine side,  fill your system with water until it runs out from your engine block, replace the hose, start your car turn you heater on and set to hi keep the radiator cap loose until the temp start to rise then close tight.  Once the air pocket had been remover you can drain some of the water from the radiator using the lower drain plug and add antifreeze.

Why would 2002 ford ranger 3.0L temp guage stay on extreme cold after water pump replacement?


i would think there is an air lock in the coolant system , have you run the engine whilst at stand still and opened the heater control to the hot position and leave to run for 10 mins or so , let cooldown then check coolant level

1995 mitsubishi Galant 2,4 v6 overheating replaced thermostat and flushed system fine for a while with some rise in temp at times now pressurising water out header tank and temp gauge does not move above...


a few things to check before we condemn it as a leaking head gasket(pressurising water out).
First check the radiator cap seal,no cracks and that it takes some pressure to push the spring loaded part down.
Does both the top and lower radiator hose get hot as temp gets to normal(where thermostat should be open).if not,the thermostat may be a faulty one or has slipped out of seat as the cover was bolted back down onto it.(temperature will differ either side of it).I have had some of these come in with part of the waterpump impellor rotted away.same symptom of one hot and one cold hose,and water doesnt flow inside radiator with cap off(ensure this is not removed if engine is hot)and temp where the thermo should be open.
Possibly the radiator needs sending out for the top or side tank to be removed and each tube cleaned out.this is a lot more effective than trying to reverse flush with water only.
But if temp is normal these areas should be fine.
Do the hoses swell with pressure and become hard to squeeze in a short time?this could reveal a leaking head gasket and should be tested with a teekay type tester for the presence of cylinder gases in cooling system.
Do the fan(s) come on if sitting idling at normal temp for 5-10mins?water can be pushed out if they dont come on or their cut in/out temp is incorrect.hope this helps.
let me know some times re when it pushes water out,do you hear a boiling sound from inside engine or radiator when this happens,any other info that may help diagnose.

Sounds like you have a blown head gasket or a cracked block, pull the plugs and see witch one is wet that will be the cylinder that is leaking.

I have a bmw318 on a 94 plate have had the water pump checked the thermostat checked and had a new radiator fitted the system runs fine when cold but when reaching normal temp the hoses become solid and...


sound to me like you have a blown head gasket, try letting it heat up with header tank open and if coolant overflows when you give it a rev up this would tend to confirm it,check also for water in oil or oil in water, water in exhaust all point to head gasket or head crack problems.

Cressida still pegs temp guage????????


1st do you loose water from the header tank or water dripping anywhere under car when stopped yes or no if yes to loss of water from h/tank then the problem is you have a Head Gasket blowing compression into the water jacket next to the cylinder,and its only small now but will get worse very soon, so get the Head removed and cracked tested and Head surface ground .

OVERHEATING


Normally it is the head gasket not the manifold gasket that causes overheating, it does it by cracking and allowing water from the coolant system to be blown out of the exhust or get dumped into the sump.

When you start the car is there water coming out of the muffler

If not then dip the oil , is it like a thick chocolate milk shake

Final check is to take the cap off the radiator or header tank and see if there are lots of air bubbles coming up.

Any of the above means a shot head gasket
