Question about Honda Cars & Trucks
I have a 93 Honda accord with 115,xxx. I been noticing after it's been ruining for a while, it starts to overheat and the coolant in the resevior and bubbling and starts to leak out. I replaced the thermostat, and I still have the same issue. I seen online that it could possibly be the head gasket. I checked the oil it isn't milky and I also checked the coolant and there isn't any oil in the coolant. And there isnt any white smoke coming from the exhaust either. The car runs very smooth and quiet, you can barley tell that it's running. I took it to a mechanic, and he perform a leak down test, and said it wasn't the head gasket. He told me that it was alot of air in the system. He said he burped it and got all the air out the system. I drove it that day I got it out the shop and it seemed to be fine. I drove it around two days later, and the same problem happened again where it was bubbling out of the resevior and leaking out. I went to my local O'Reillys and the guy told me it could possibly be the water pump is going. Just want to know what could this possibly, because I don't want waste money fixing something and it still does the same thing. Thanks
Keep in mind what I am going to say is via long distance. I would need to check it myself to make any solid judgements.
The leak-down test would show a leaking head gasket IF the gasket is leaking all the time. But it is possible the gasket is only leaking when the engine is hot. A leaking head gasket is the most common way you get extra pressure (bubbles) in the cooling system. The head gasket can leak when the engine is hot and you would not always see oil in the coolant or coolant in the oil as you would if it leaked with the engine cold.
Another problem could be the radiator cap. It may not be able to hold 15 or 17 psi of pressure when the engine is hot. If the coolant is not under pressure it can boil (bubbles) before it reaches 250 degrees.
Another factor is the radiator and fan. If the fan is not running when the engine reaches 220 degrees, or the radiator is not able to dissipate the heat from the coolant, the engine can run ok until it gets to 220 degrees then keep getting hotter.
If the water pump were failing, it should start overheating right after you start driving the car.

SOURCE: White smoke from Exhaust
hardly likely the exhaust job would cause that, but yes it sounds like you got a blown head gasket. badl lock stricks hmm! also preasure test cylinder head for leaks

One of the gaskets has blown at a point where the a water jacket is blowning into the cylinders but not mixing with an oil jacket on the heads. Try to use some Bars Leak and see if you can get it to seal and if not, their are also aluminum shavings mixed with sealer for some of the worse problems. If it seals you will then know that it will need a gasket replacement at some point
