    yes i did and everything that is necessary to do when changing head gasket.

    one more thing, the radiator volume is 1,5L. but it was the same when it was working normal.

    the fan is on all the time, I replaced the thermostat I dont thikt they put it in backwards, thermostat is used. Radioator have some paint at front not much, and it is not complete there is 1/3 of radiator, beffore that was not a problem, it is losing antifreeze but no one knows where.

    when I start enginte in 5minutes it is overheating

  • enis786 Apr 25, 2009

    oil is OK, there is no visible antifreeze leaks, engine is 1.6 B6 62KW.

    What can be a problem, I mean engine is overheating after 5 minutes, standing in place.

    Make sure cooling system is not air locked. Check your manual on how to refill cooling system. Do you have white smoke coming out of the exhaust when you first start it? You could have a stuck shut thermostat.

    What size motor?

  • Dennis Yachimec May 11, 2010

    Did you check your oil to see if it is a milky color?
    Do you have any visible antifreeze leaks?

  • Dennis Yachimec May 11, 2010

    Is your fan coming on? Did you replace the thermostat? Is the radiator clean on the front? Are you losing antifreeze? If new thermostat, did they put it in backwards?

  • Dennis Yachimec May 11, 2010

    When you changed your head gasket did you get the head checked to make sure that there where no cracks in it or that it was not warped.

All i can think of is the thermostat is not opening. or you may have a clog somewhere preventing the flow. Check the T-stat and hoses and radiator ( for clogs) Good luck

My mazda tribute is overheating alot

Hi and welcome to FixYa!

There are few things that can cause the vehicle to heat. Please check the following to resolve the issue:

- A faulty water pump can cause the car to overheat. If the water pump is faulty the coolant will not circulate properly on the engine which can result to overheating. You will need to have it replaced if that's the case.

- A worn out or damaged radiator hose. Just a small hole on the hose can cause the vehicle to overheat so have it replaced.

- A weak radiator blower motor. If the blower motor is weak it tends not to cool down the engine so have the blower motor replaced.

These are the few things that can cause the car to overheat so please have the following be checked.

Hope this helps and thank you for using FixYa! Have a good one!

Changed bad water pump and timing but car is still overheating causes

Overheating is not always caused by a bad water pump or bad engine firing timing.

The most common causes are:
  • faulty radiator cap: steam/water will be escaping from the caps when engine is hot or oveflow tank overflows or empty!
  • crack cylinder head gasket: check when engine is cold thru radiator cap hole for milky oil in water radiator or large bubbles in radiator water after starting engine. Also check if water steam comes out of exhaust.
  • cylinder head itself: same symtoms as for gasket above.
Hope it helps you find your problems.

Cylinder head gasket

hi, if you are changing the head gasket then it may be worth checking the water pump and thermostat as it could have been one of these that failed causing it to over heat and then blown the head gasket so check the water pump and thermostat once you have the cylinder head off.

You may need the head checking to see if it has been warped but this is unlikely on this make of vehicle.

Once you have done the gasket make sure that when you fill the coolant up you only trickle the water in to prevent any air lock as this will cause it to over heat again, check for any bleed screws on the coolant system to let the air out whilst filling the coolant up,

Its best you check in the workshop manual for these as their may not be none as it could be self bleed system.

It also worth checking if the head bolts need changing as they do stretch and can cause the gasket not to seal properly so replacing these may be a good idea.

Let me know how you get on or if you need further assistance ok.

ps what makes you think the head gasket has gone??

Engine overheating full of water

Before to look a new radiator, check for no leaks any where, thermostat, pump, head gaskets. If this its ok, if the fans on right check fan clutch, make sure water is topped off, if all is ok, then replace the water pump thats the last thing you need changed.

Good luck (remember rated this help).

Mazda bongo 2.5 turbo diesel 1996. over heating

no im a mechanic it sounds like that you have an air lock in the cooling system .i am familiar with ford freda and bongo and the design where the engine is is a bit far from the radiator ,so the problem with air locks magnifies.really the solution is just drain the water and refill it slowly while you are pressing and releasing,just repeat the action on the top radiator hose to get rid of any air trapping within the system,it's as simple as that want it to have just water and no air as this will cause a blockage.
