Hi, I have civic 1995 coupe. The car overheat every time when I drive it or when its park and running. I took it to the mechanic and he told me that the water pump was licking so it needed to be replaced, he changed that and timing belt, but theproblem wasn't fixed. He checked the car again and he said that could be the head gasket, then he did replaced the head gasket and replace the old thermostat. but that didn't fix the problem, then he decided to flush the radiator and check the hoses, he told me that everything is working fine and the car should no overheat, I took it for a ride and the car overheated again. I brought the car back and he checked the fan if it was working and it was working fine. he doesn't know what could be causing the problem so I have no idea what should I do with the car.
Thanks in advance for any advice

^^ x2.......You might also try bleeding the system. Do this with your car parked on an incline, or with the front end on jack stands....

Geez, sounds like your mechanic did almost everything.

Are you having trouble with your car overheating? It can be a frustrating problem to deal with and diagnose. This article will go over some of the most common reasons why cars and trucks overheat.

One of the most common reasons for a vehicle overheating is a stuck thermostat. It can stick or freeze in the closed position blocking the flow of coolant to your engine. The easiest way to check if your thermostat is not open is to feel the upper radiator hose. Once the engine warms up it should become warm. If it does not get hot the thermostat is probably not opening.

A second common cause of overheating is a leak in your vehicle's cooling system. If your vehicle is loosing coolant there will not be enough left in the vehicle to keep it cool. This is easy to diagnose as the radiator will be low on fluid and there will probably be a pool of coolant on the floor of your garage. Look for leaks in the most common places like around hoses and around the welds of your radiator. If you can not find the leak you might need to take it to a shop to have the cooling system pressure tested.

The third cause is a faulty water pump. The water pump is a vital part of your cooling system since it is responsible for circulating coolant through your engine. With a faulty water pump your vehicle will not run for more than a few minutes without overheating.

The fourth cause of overheating is a bad cooling fan. There are two types of fans, electric and mechanical. The electric fan should come on automatically once the vehicle reaches operating temperature or when the A/C is turned on. If it doesn't you should have it replaced. The mechanical fan will run all of the time but has a clutch which makes it turn faster when the engine heats up. With the car turned off the fan should not turn too easily especially when the vehicle is warm. You can also check for signs of leakage from the fan clutch. If you see any problems have it replaced.

The fifth cause of overheating I will talk about is a clogged radiator. Over time the radiator can accumulate deposits of rust and debris. This is especially true if radiator fluid has not been flushed on a regular basis. If you suspect a clogged radiator you should take it to a shop to have it professionally cleaned.

Those are some of the most common cause for vehicle overheating. Vehicle overheating can cause a great deal of damage to your vehicle. If you are experiencing trouble be sure to fix your vehicle or take it to a quality mechanic as soon as possible.

Does the fan switch on when you are parked while the engine is running? I use to have this problem, and i replaced the thermostat and fan switch and problem was fixed for good. Total cost was less than $20. You should check this. Good luck and screw your mechanic playing guessing games taking a stab in the dark.

I tried boht and the car still overheating, anyways I talked to another mechanic and I told this guy all the work that the other mechanic had done to the car and he said "the block its cracked".
I checked the oil this morning and it looked clean, (no milky) and no tinny bubbles in it. car doesn't run rough and there is no white smoke. So can he be right? can the block get fix? if yes how much would it cost? how much would be a used one? I ask these question as a reference b/c I have no idea about prices

ask your mechanic to show you the parts he replaced... almost everything that has to do with the cooling system has been replaced.

ok i hate to suggest this because its usually NOT the case and its a pain to check... look at all your coolant hoses, i mean all even the heater core hose, that one on my car was the culprit that caused me to go on a cooling system goose hunt. also your heater core may be bad, for the age of the car it is becoming more common, but again its a pain in the ass to check. i do not recall reading, are you running out of coolant? if not it can also be your temp sensor-sender unit. there is still a lot un-tested, a simple coolant test can tell you if you are working with a blown gasket/block sleeve. what are your compression numbers?
so in order of cheapness and ease of tests
1. radiator cap
2. thermostat
3.temp sensor
4.coolant test
5. hose replacement
6. radiator replacement
7. heater core

Well, I took the car to a different mechanic, he did some test on the car after i told him what another mechanic did on it, he came with a brilliant solution, "change the engine", that would cost me $ 1200. I've try everything that I possible can and I can't spend more money.on this car, I have no clue what that hell its wrong with this f....! car. I give up.

What you can do is directly connect the fan to your battery and see if that helps the problem at all. But first check to see if your cooling fan is engaging
