    Would that be a warranty issue? The truck is actually a 2006 with 90,000 km on it

  • perry freake Mar 04, 2009

    Yep we "burped" it than drove for about 200 km when the guy who was driving my truck noticed that it was starting to over heat on the hills (had not done this previously). when we checked the resevoir had dropped considerably

Did you drain coolant before you changed the thermostat? If you did and you just filled up directly after, the system didn't get bled. You have to have vehicle running with radiator cap off, then fill and let it run through, fill more and more until it doesn't get any lower anymore, you can also gently squeeze the radiator hose when pouring coolant in also helps bleed the system.
To properly fill and bleed the raidiator and coolant system, should actually take about 10 - 15 minutes.

When you first pour fluid in it will go to top of radiator or reservoir, then it will slowly drain into engine block, then you add more and patiently wait for it to drain in engine block, keep doing this until the entire system is full and level no longer drops.

How do i fix an engine which is overheating?


there are only two causes of overheating - and that applies to all engines in existence...

1. insufficient lubrication
2. insufficient cooling

best proceed with cold engine, on level ground

re1. check lubricant level and flow, check lubricant condition for presence of foreign mater or liquid, best, change oil and oil filter.

re2. check coolant level, including overflow bottle, if insufficient - add coolant. check coolant condition and flow. do not close the cap, start the engine, check for presence of bubbles in the liquid while engine is running, if there are bubbles present - it can indicate blown headgasket, especially if distinct smell of fuel is present. switch off the engine and feel top and bottom of the radiator, it should be same temperature or very similar, if it is much colder on the bottom than on the top - there are two possibilities, thermostat is gone and need to be replaced or too much gunk in the radiator and need flushing.

hope this will help you - do not forget to vote...

How do i change the coolant/flush radiator in 2004 ford freestar


Open the petcock on the bottom of the radiator and allow the old coolant to drain.

Close the petcock.

To refill you will first fill the degas container to the cold fill range, leave the cap off the canister. Turn all of the heater controls to warm and turn fan to full. Idle the engine until the thermostat opens. Top off the coolant and put the cap back on. Idle at 3000 RPM for several seconds and then idle again for a minute or so. Check the level and then repeat this 4 times, or until heat is coming from the front and rear heat units.

If you want to flush the system you will have to remove the thermostat and hook up your flush system to the radiator hose at the thermostat housing. Follow the instructions on your flush system then put the thermostat back in. Follow the instructions above to refill.

Need diagram where bottom radiater hose attaches to engine where it appears to be leaking


This is how I like to do it. Make sure the car is parked with the front end at an upward angle. Drain the coolant from the petcock at the bottom of the radiator. Remove the upper and lower hoses at the radiator. Remove the thermostat housing, and the heater core hoses at the fire wall. Flush out the radiator by pouring fresh water into the overflow, and the hole where the thermostat was. Flush the heater core as best you can by pouring fresh water into the heater core hose connections.
Let all the water drain out, then button everything back up and replace the thermostat with a new one. Refill the rad and engine by filling the coolant reservoir with a mix of 50% water and 50% antifreeze, or buy the premixed stuff from the auto parts store. (Buy 4 jugs of premix or 2 of straight antifreeze)
Run the engine until it reaches operating temperature and the upper rad hose gets hot. Rev the engine a little to help get the air out of the cooling system. When the thermostat opens, the coolant level will drop in the reservoir, so top it up and replace the cap.
Check for leaks, and check the coolant level for the next few days, and check for leaks.
Dispose of the old coolant responsibly

2002 pt cruiser overheating was told i need a new raditor and thermostat for 1 grand sounds fishy


Flush rad & change coolant & thermostat. Check operation of rad fan, & make sure it is coming on when engine reaches normal operating temperature. Be sure to bleed air out good when refilling rad/cooling system. Start engine & turn heater on when refilling & let rad fan come on & off at least 2 or 3 times before putting cap back on rad, and refill rad as needed as you do this. then fill return bottle to proper level & see what happens.

I have a 2002 Chrysler Town and Country minimvan that has a 3.8L V-6 engine. Water gets out of radiator but no leaks are seen under vehicle. Water in reservoir tankstays full even though radiator is low of...


You may have a faulty rad cap, grab a new one at autoparts store, and try this first. With engine cool, take rad cap off, start engine & turn heater(not defrost) on. Top up coolant in rad to 1-2" from top. Let it run with cap off and add coolant as needed, until the engine reaches normal operating temperature, and the rad fan comes on, then shuts back off. Let it run like this until that fan comes on & off at least 3 times. Add coolant as needed in rad, while you watch it, and rev engine slightly every once in a while for 5 or 10 seconds. After rad fan has come on & off 3 times, make sure to top up coolant to 1-2" from top in rad, and put your new rad cap on all the way, and now lets see what happens. If at any time the temperature gauge goes up too close to hot, shut it off, let it cool down & try again. Top up coolant bottle to marked level .Let me know. It should now run normal temperature and have heat as required. If yu feel ambitious, it never hurts to change thermostat if it hasn't been done in a while, but at this time, it may not be necessary. My guess is problem is faulty rad cap & an airlock in your system. After all this is done, if all seems o.k. keep an eye on coolant level, my guess is it will be o.k. , if not get back to me.

Coolant problem


Sounds like you might have an air pocket in the cooling system. This can develop, usually after a service, where the cooling system has to be opened to replace a water pump, thermostat, or other reason. When refilled, the air displaced by coolant has to go somewhere. In many cases, youll find that air is trapped in the highest place it can go...above the level of the radiator cap or overflow bottle. This can be a portion of the upper rad. hose, a heater hose, or a coolant line running thru various parts of the intake/throttle body area. What I do after topping up the system, is let the engine warm to normal op. temp./ W radiator cap still off. When upper hose becomes hot, you know thermostat is open. Now, if a bleeding device is not present, back off a hose clamp at the highest point in the system. Take a pair of pliers and twist the hose just enough to break the seal. You should see steam or drops escaping from your "breach". Once the steam stops and becomes all coolant, you have likely bled all air from the system. Top up radiator and coolant bottle to proper mark and close the system. (tighten your hose clamp) Check for leaks. Keep an eye on your system for a day or two, to insure no leaks are present.

Road

Caution! As with any task that involves opening the cooling system...Coolant and water can become very hot. Hot water and steam can be very dangerous. If you dont feel qualified to perform this task, let a mechanic do it!

'98 Century--Sporadic over-heating


Be sure to have heater (not defrost) on when refilling rad with coolant, and leave cap off until rad fan has come on & off 2 or 3 times, then replace cap. Airlocks are common on vehicles cooling systems, and will cause symptoms you are describing.
