Might suggest you do a compression test and see if you have a low cylinder, which might indicate gasket failure

Four bolts hold it onto the support bracket. Remove both radiator hoses and disconnect the electrical connections to the temp sensor and fan sesnor. Take out the 4 bolts and lift up and away. Transfer the sensors from the old radiator to the new one. Do not mix up the locations of the sensors. Re install the radiator, put back the 4 bolts and reconnect both radiator hoses. Fill the radiator with the correct mixture of antifreeze and water for your vehicle. If it won't all go in, start the engine and let it run until the thermostat opens and then finish adding the coolant. Add water to the radiator until water can be seen circulating. Add some water to the overflow container and put the cap on the filler neck. Run a little longer then shut the engine off. When the engine has cooled off check the level in the overflow bottle and add coolant to the mark.

What is wrong with a saturn sl1 indicator says it is hot after running for 5 minutes

John sounds like your sensor may be bad. Next it could be your thermostat sticking use a temp gun and measure the temp of your radiator at the cap. Do not remove cap. Just take temp. If it is getting hot it should spit water out. Check to see if the electric fan is coming on the sensor to cut the fan on maybe bad or the fan. Hope this helps.

Radiator overflow bottle

Any bottle should work, capable of withstanding the heat and chemical. Be sure you're using a cap designed for coolant recovery, a hose into the bottle at the same height or lower and the hose reaches to the bottom of the bottle suck the overflow back when the bike cools down.

Where do u put the water in on a colt? Can't find it?

A tank used for storing excess coolant; connected to the cooling system with a small-diameter overflow hose.

The coolant reservoir is the bottle,under the hood, that holds the radiator fluid. it is also known as a overflow bottle. When the car gets hot,the overflow bottle, releases steam to relive the pressure in the radiator. excess coolant is also stored here.


I hope this helps, Mike from fixya.

Heat is not working - coolant was low so filled it.... problem here... heard something about an air pocket

If you dont have an external coolant leak anywhere under your hood that has shown up on your driveway it could be the intake manifold or the headgasket leaking. Also check the thermostate to solve the heat issue.

I just got a 97 fzr 600 how do i check the coolant level

With the engine cool, locate the radiator cap on the right side of the motorcycle under the fake tank (the real tank is under neath a plastic cover). You may have to take off the right lower cowl. Remove the cap and fill the radiator to the top. Now, take off the seat and fill the overflow bottle to the high mark. You can follow the overflow tube from the over flow bottle to the radiator cap and vice versa. Ride the motorcycle and check the over flow tank level again after the bike cools down .

Bleeding Air from Cooling System

With the system cold, fill the radiator with a 50/50 antifreeze and water mixture - fill it all the way to the top, then put the cap back on. Now, fill the plastic overflow bottle about 1/2 way with your antifreeze solution.
Ride the bike until normal operating temperature is achieved (or longer, if you like). Now park it and let it cool down again. Then, check the coolant level in the overflow bottle and add more antifreeze, if needed.
When you operated the engine until normal operating temperature was achieved, all air trapped in the cooling system gets pushed out by the expanding coolant (out through the overflow bottle and into the atmosphere). Then, during the subsequent cool-down period, only liquid is drawn back into the radiator from the overflow bottle as the engine coolant cools and contracts, not air. From this point, as long as the radiator cap is not removed - and the overflow bottle is maintained at the 'full' level, no air will enter the system.

Cooling system over flow system. and how it works

The overflow system has a different radiator cap than on yesteryears cars. The old cap would let extra water vent out of the radiator and you would lose that coolant. The newer radiator cap lets water go both ways through the vent tube. Then the overflow uses a tank to catch and return the water. It siphons the fluid back into the radiator.

The system was invented when the thermostats were set at 205degrees and up for pollution systems. It also saved some aluminum with smaller radiators and using a plastic overflow bottle instead of a bigger metal radiator.
