I recently got the water pump replaced and the car over heated. I thought this was because of gunk in the radiator, so I got the radiator flushed out this week. The car STILL overheated though!!! When I stopped the car, I could hear bubbling from somewhere in the engine, but it is not the radiator. The bubbling was coming from somewhere over on the right of the engine. The car is a Mazda 121.

I had the whole system flushed out not long ago. And also have had it checked for air bubbles - there are none.

try having your system flushed - Basically, they run all of the fluids out of your engine, clean the workings all out, and then refill it. It shouldn't run more than maybe $100.

i haven't heard of a mazda 121, however,depending on the year, i will asume it is at least a mid 90's, most vehicles that were front wheel drive[especially GM cars] you have to occasionally "bleed" the cooling system after any type of work has been done on it. There is typically a bleeder screw mounted on top of or right beside the thermostat housing. When the car is runnin loosen the screw before it gets too hot,as the car heats up,loosen it a bit more,there should be steam coming out, when you see water flowing out, you know it has no air in the coolant line,the air is what causes the overheating. fill the radiator back up,your in business.

Could be a number of things, bad thermostat, leaky hoses or rad cap. Could be your sending unit went bad & is reading faulty, this happens some times after an engine actually did overheat & the sending unit went bad. Radiator core may be plugged to much for flushing & needs rodding out instead. The best thing is to have someone u trust look at it. It's impossible to say acurately without looking at it. A bad thermostat will cause an engine to bubble & get hot, they tend to stay closed thus not allowing the fluids to run through the engine properly.

Well first of all I can tell you that it is not your head or head gasket being cracked.........(as stated by srtransmision) If that was the case, there would not be any pressure for you to hear the bubbling , also, you would notice that water is mixing with the motor oil. (milky white mixture under the oil cap). I can certainly guarantee that it is your thermostat stuck closed and the bubbling you are hearing is where the water is being pushed into the antifreeze reservoir which is usually mounted on the finder wall.

If air is effervescent into your tank, that continually signifies that your head gasket is leaking. do this popular, although. bypass to a diy automobile wash and potential WASH the gap between the radiator and the A/C condenser, the position computer virus bodies, leaves, paper, seedlings and animal droppings have accrued. this can fix air go by potential of radiator and keep issues cool. potential wash engine too, on the grounds that extra warmth receives dissipated from a sparkling engine block. examine top and reduce heater hoses to be sure in the adventure that they are the same temperature. If there's a clog, one hose will be hotter than the different. in contact about the effervescent sound.

air in the cooling system. when the engine is cool take off the radiator cap. start engine. let run until aie stops bubbleing out of radiator fill cap. coolant should begin to overflow. wait until level goes down refill and put cap back on.

I never heard of a Mazda 121 but you may have a bad thermostat, when they replaced the waterpump they should've replaced, or at least checked your thermostat.

the problem with your car is and I'm 99% sure that the head gasket or engine head has cracked.compresion from cylinders is leaking into the cooling system causing it to over.take it a shop and have it tested for an "ENGINE BLOCK LEAK"it takes few minutes via the radiator

If you did all that your thermostat is stuck shut.Its at the end of a big hose on the top of the motor.
