Question about 1990 Mazda MX-5

1 Answer

1990 mazda miata

My car does not overheat,but the hose that goes from the radiator to the overflow reserve tank leaks while idling and when I drive the car and turn it off, the reserve tank is almost empty of antifreeze and I have relaced the radiator cap but it leaks quite a bit from the opened end of the tube on the reserve tank. I have not notice any water on the passenger side floor board .when i turn the car on after it begans to get a little warm up , it squirts antifreeze from the hose on the tank, and after i turn the car off.

also the fans that are behind the radiator,are they suppose to run all the time ? or just when the car heats up?

Will pepper swtop a radiator leak
Improvement done by sickofjunk
There are radiator sealants available at many auto parts stores. I personally have never been able to get them to work though another good way to seal a leak if it is on the aluminum part of the radiator is to soder it with silver soder. And no i don't think pepper will stop a radiator leak.

1999 chevy express van.I have two hoses that run off of my reserve tank one of the goes to the radiator. and another hose that looks like it goes on the acumlator


From the reserve tank, one hose should go to the radiator and the other should be for overflow. Sometimes that one goes to an accumulator, sometimes its left dangling cause its just there to drain any excess fluid from expansion in a hot system. Depends on the vehicle. If its in an enclosed system or plugged you would get an excess of back pressure which would further heat up the coolant and inhibit flow. Just leave it there. If it pukes coolant when hot then its doing its job. Don't overflow your reserve tank.

Dodge neon overheating


I would be thinking radiator or water pump. When the engine is warmed up and the upper hose is hot, feel the lower radiator hose. It should be hot too, just a little cooler than the upper hose. If there is some blockage in the radiator, the lower hose may feel cold or just lukewarm.
Even though the water pump doesn't leak, the impellers may be made of plastic and have considerable wear. That would restrict circulation.
The heater core should not be an issue. Heater cores do not cause overheating even when totally plugged up.

Overheating coolant boiling out into reserve tank


you have a blown head gasket.. doesn't have to have coolant in the oil for a blown head gasket... if hoses are rock hard when running then you have exhaust leaking into the coolant via a blown head gasket...

Have to keep adding water to overflow tank...Code read PO117 for mazda miata MX5


You have a leak in the radiator, water pump, a hose, the heater or a head gasket. Check these and see if there is any water coming out of the exhaust or in the sump.
Take off the radiator cap, fill it right up to the neck, start the engine and warm it up. See if there are any bubbles in the top of the radiator, keep it topped up so there is no room in the top tank.
If there are continuous bubbles then there is a leak in the head gasket.

I have a 2002 jeep grand cherokee and am having coolant problems. Every say 2 weeks or so, the coolant low level warning will come on and the overflow tank will be empty. radiator is still full though...


The hose is an over flow drain. If you've seen no signs of leaks then most likely your radiator cap is bad. The cap helps to pressurize the cooling system, if it is bad it allows to much coolant out to the over flow tank and the extra is dumped while your driving. When you turn off your engine the fluid is drawn back into the radiator and your coolant mysteriously disappears.

I have a 2001 chevy Malibu. Have problems with


Due to the complexity of the newer cars on the raod today!! what you are experiencing is Normal!!! since the coolant systems on the newer cars run at such a higher pressure and a high Rpm the reserve tank which has it's on drain hose for excessive overflow from the radiator allows the extra high pressure release from the radiator to back flow to the reserve tank and then out the reserve tank overflow hose on to the raod

2002 mazda miata mx5 has strong gasoline smell in trunk. Had smoke test done at dealership and showed no leaks. Help.


The fill pipe is right back there. Check to see if a hose has been damaged. Check the spout area, is there a overflow pipe or a seam that could be leaking into the trunk?
