It overheats to quickly but how much should it cost to get both head gaskets cleaned, pressure tested, planed, timing belt changed and a radiator flush on a 2litre v6 1994 mazda astina 323

Hi
If you haven't ever done one then i suggest take to a garage.
You need to take the engine head off.
Timing belt off.
Radiator flashed / change
all water hoses off and cleaned.
head pressure tested
head skimmed.
Oil flush
New oil and oil filter.
Its not a simple job. whilst everything is open. change the timing belt and water pump as well.
check the radiator for blocked cores. have a radiator shop do a flow test. I hope that you put the thermostat in the correct way around. check the cooling system for air locks in the system
I don't see any mention of having the cooling system flushed or the water pump being serviced. Both could be creating your problem. Also are you sure the new head gasket was installed properly, the right one and not upside down.
The only other thing I can think of is maybe you put in the wrong kind of coolant? Not every type of coolant works in every car. Other than that, try head gasket sealer because if your head gasket is leaking, it can't be a big leak, otherwise you'd have problems right away.
Head gasket between engine block and valve header is leaking coolant into engine oil crank case. Expect a major costly repair because mechanic has to remove many parts to replace head gasket. If you have not overheat the engine, it may cost less. Because overheat engine will damage other components such as radiator,water pump, main seal, oil seal, timing belt.
I would recommend that you bleed all air out of the cooling system. The bleeder valve is located on top of the engine. Once engine starts to overheat or when you can hear bubbling back into the overflow bottle, turn car off and open bleeder valve. If you see bubbling you have air in your system. Bleed the system a couple of times and see if this helps.A heat sensor sending unit which controls activation of the electric fan could also have failed.But if the heat sensor is properly working then check the radiator cap is it properly fitted or got loose.If its loose it will release the pressure and car will overheat.But if the radiator cap is properly closed.Then its time to check the HEAD GASKET.As you have replaced the head gasket still get it checked is it overheating very quickly or is the head gasket placed properly also check the coolant level in the car.Thanks. you can rate this solution and show your appreciation.
before you start taking it to bits have you checked thermostat is opening ok and that radiator is not blocked also that the cooling fans are working a chemical test or sniff test can be done to check for gases in cooling system these engines are strong not prone to head gasket problems
YOUR WATER PUMP COULD BE BAD.CHECK TO SEE IF WEEP HOLE LEAKING IS SO REPLACE IT IF NOT.MAKE SURE COOLANT FAN IS WORKING.HAVE RADIATOR SHOP PRESSURIZE COOLANT SYSTEM.TO CHECK FOR LEAKING HEAD GASKET.ALSO HAVE RADIATOR SHOP FLUSH RADIATOR.IF ITS CLOGGED UP.IT WILL CAUSE OVERHEATING PROBLEMS.ALSO MAKE SURE YOUR ENGINE COOLANT MIXTURE 50% WATER 50% ANTIFREEZE.TOO MUCH WATER IN RADIATOR WILL CAUSE OVERHEATING.
