    i have a 89 acura integra that is running just above the middle on the white temp line. i have had recently a new radiator and within the last year a new water pump and thermostat. but its still hotter than it should be i think. the fans come on i know when the a/c is on for sure but not sure when the a/c is not on. the old radiator had tons of corrosion and alkali/ calcium build up so i'm wondering if that could still be in the block somewhere and causing the poor circulation still. and if so what can i do about it? my email is tremonti23@gmail.com

    Out of curiosity have you verified the temperature that your gauge is showing you? When you say it gets hot, are you using the gauge in the dash as a reference, or is it getting hot to the point where you're steaming over, blowing radiator cap gaskets, etc? I ask, because if you're going by the gauge in the dash, keep in mind that those gauges can go bad with little notice. If you've ever overheated seriously, it is possible the temperature sending unit may have been damaged and is now reporting inaccurately. In fact, the sending unit might have just gone on it's own, as well. Also, don't confuse the sending unit with the temperature sensor. They are two separate entities. One reports to the ECM, the other sends the temperature to your gauge.

    There are a few other things that could cause overheating conditions. The radiator could be plugged. You could have a leaking head gasket that is allowing exhaust gas in the cooling system. Did the vehicle overheating causing you to replace those things, or did you notice a leak from the pump and replace it without it overheating first?

New thermostat, fan switch , fan comes on, still overheats . Upper hose hot, same lower hose but both are hard feels like the water is not circulating . Bad water pump, or head gasket ?


Most likely pump. Head gasket will usually put hot gases into the cooling system and will appear as bubbles in the cooling fluid container. It may also feed lubrication oil into the coolant. The coolant pump is driven by fan belts. Make sure you are not missing any belts.

I have a 1996 Acura Integra. I recently drove my car and found that my gauges were showing that it was overheating quite substantially. I checked the engine itself to make sure it wasn't my gauges...


Check if the Fan is working normal, also check if the water is at the normal level. Make sure the water is not filled up because it has it normal water level.

Acura Tl 3.2 1996 sometimes the tempeture go to the max and then after a few seconds go back to normal, the thermostat and the water pump are new


  • There is only so much that will make your cars temp spike like that. You got a new pump and thermostats so considering they were put in right and functioning properly we'll go from there.
  • First thing you want to do is make sure the fan is coming on when the temperature rise. The fan malfunctioning will cause the car to overheat just like that. The fan relay could cause this malfunction along with wiring issues. The fan relay will be under the hood.
  • You want to make sure your radiator is sealing correct. If you have a bad radiator cap it will not hold pressure and can cause some overheating.
  • Make sure to change/flush your antifreeze every 30,000 miles for green and 50,000 for organic antifreeze. When antifreeze gets old it begins to break down and will not keep the engine from over heating. Make sure it is mixed 50/50 and not to this or it will not work properly either.
  • Hope this helps.

Regards, Tony

Thermo valve broken, does this cause over heating?


if you mean "thermostat" valve .. then that can fail either open or closed . if it fails open then the engine will not reach normal operating temperatures .. if it fails closed then yes the engine will overheat .. another common failure is the radiator fan .. it only runs when the car is not moving .. as long as the car is moving then cooling air is available so the fan is not needed ... so if your car does not overheat when driven but overheats when stopped or idling then suspect the radiator fan or thermal switch (mounted on the radiator) .. that switch turns on the fan when the radiator gets so hot ... you can just listen for the fan when hot .. you should hear it .. .. if your car gets too hot while driving then suspect a bad thermostat or clogged radiator .. sometimes a bad water pump (broken implellers) will cause the trouble ..

Can i put a 1994 acura integra ls trans to replace a 1989 acura i


I don't think this would be possible wihtout some hassles.

The engine type build changed twice between the 89 and the 94 series integra.

I would suggest you speak to Honda specialised mechanic before you purchase the 94 tranny.

Also check out the Honda forums as they ahve guys who have done some handy things with the ol integra

If the cooling system has no bleeder valves to vent air, you may have to temporarily loosen a heater hose to get all the air out of the system...Also check to see if there is water in the oil...If there is water in the oil then it could have a head gasket problem..Did you ever replace the thermostat? If it is stuck then it would also cause overheating...Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.

My 1995 toyota avalon is overheating. When this happens, antifreeze fills up my reservoir container, even when I didn't put that much antifreeze in it.
