Question about 1999 Ford Mondeo

Ford mondeo problems

We replaced the thermostat 3 weeks ago due to the overheating and all seemed ok,but now the car is overheating yet again.It stays at normal for a short time and then almost reaches the red overheating warning.We have no idea if it's the pump,a blockage or even the fan and wondered if anyone can advise as to what the problem is.As Oap's and hubby not mechanically minded whatsoever and no appropriate tools for using (as always)could the car be on it's way out and ready to scrap as we are constantly throwing money at it lately!

SOURCE: ford ranger truck overheating

I have had this happen with my ranger. Changed everything I could to try to fix the over heating. It turned out that I had a small leak in my head gasket and it was allowing exsaust gas to go into the cooling system witch was over pressurizing it. Also the air from the exsaust will heat up much faster than liquid making your thermostat to read hot and will not be able to blow hot air in the cab because there is no liquid going to the heater core. This happened to me when my blet came off and I tryed to make it home. If you had it over heat for a long peirod of time it may have ripped the head gasket.

You most likely have air in the system. These things can be a royal pain to get the air bleed out of the system.
Look back next to the brake booster and you will see a rubber tube with a screw cap in the end of it(this is the heater bleed), also on the front of the intake area you will see a black tube with an allen sloted cap.
Remove the slotted cap and screw the screw cc on the rubber tube. Add coolant to the coolant jug allowing the system to equalize until no more coolant can be added. Add as much coolant as possible to the engine fill( the sloted cap near intake). The heater air bleed will remain open.Replace the engine fill cap.Start the engine and turn the heater to MAX position.Close the heater air bleed when a steady stream of coolant comes from it, during engine idle. Allow the engine to idle for five minutes, add coolant to the degas bottle as needed to maintain the cold fill MAX mark.Reopen the heater air bleed to release any entrapped air and close again. Maintain engine speed of 2,000 rpm for 3-5 minutes or until hot air comes from the heater.Return to idle and verify hot air is still coming from the heater. Set the heater temperature setting to 75° F and allow the vehicle to idle for two minutes.Shut the engine off and allow to cool.After the engine has cooled, add coolant to the degas bottle to bring the level to the cold fill MAX mark. This should have the air out of the system.

yes there is a know problem with the fuel system. fuel pump breaks down, empty your fuel filter into a bowl and check for metalic, if you have this in the filter your pump is F..... along with all the other common rail stuff. expensive job... error codes though, i find that hard to believe, fuel pressure faults will occur, i think you garage does not know what to do. or does not want to tell you the cost of the job and he will be in doubt himself of wether he is right..... was you engine coil light flashing at any point.!!!

the thermostat can be easily changed from up top, the T-stat is located at the engine end of the upper radiator hose under the flange the hose connects to. Make sure u follow manufacturer's cooling system bleeding procedures when you refill after the T-stat is changed out.

The heater on my 02 mondeo takes about 30 minutes to start working properly, if I put the blower on too soon the temperature gauge shoots down, any ideas?


It sounds like the thermostat is stuck open. The thermostat is closed until the coolant in the engine gets heated up. Once it get hot, the coolant is cycled to the radiator to be cooled by air passing thru it. The coolant that was in the radiator is cycled to the engine where it is heated - or more properly termed, is used to cool the engine to keep it from overheating and seizing. The heated coolant is used to provide heat for the cabin in cold months.

Heres a video showing the job on a 2001 Mondeo and should be pretty similar job.

Check engine light is staying on again , i drive about four miles , see the temperture hand rise and fall when the thermastat opens (replaced bad thermostat 3 weeks ago) ck eng light starts flashing @39...


Hello, If this is a Turbocharged or boosted engine, the Code 39 means there is a problem with the Bypass Valve control. It would also explain the heat retention in the motor.

You can get a FREE scan at Autozone, Advance , or Oreilys autoparts to verify the results of the "Check light". If you miscounted, the scan will still help and give a diagnosis.

I hope my solution is very helpful to you.

My 1997 subaru impreza overheats


Could be a couple of things, did they check to make sure the fans were bad before changing them? (trial and error is very expensive if you pay a shop for it). Your thermostat could be bad (not opening) your water pump too (would make this a last thing due to cost to replace). And possibly even your fan relays/relay sensor. When your needle gets high does the cooling fan(s) come on? They should. If they are not coming on then check those little things first. You may have replaced fans that were good. i would also try another shop for diagnosis. Those are small things your shop should have checked first.

Random Overheating Problem on Peugeot 206


It sounds like your thermostat has gone bad and sticking close, Replace the Thermostat and Antifreeze. When replacing the thermostat, buy a fail safe thermostat so you will not have a overheating problem when the thermostat fails. Good luck and hope this helps. Keep me posted, be glad to help.

Mini Cooper convertible is overheating, fan contiues after stop


I had this exact same problem -- for about a year and a half! Replaced thermostat, replaced sensor twice, replaced overflow tank, replaced radiator cap, placed a grounding kit on the car in case the problem was electrical ... and was ABOUT to replace thermostat again and then the water pump when a new mechanic suggested we bleed air out of the cooling system. The heater core was PACKED with air, as was the upper hose valve area. Previous mechanic had been using a pressurized fill device to bleed the system and this had just been backing air into the heater core. There are two valves under the hood for bleeding air -- one on the heater core and one on the upper hose. It only takes a few minutes to fix this!
