The story:

I had my stock radiator crack, replaced it with a mishimoto one, I had 2 leaks the hose that goes from the rad neck to the hard line that feeds the overflow, fixed those saw that my over flow was low, put in more coolant mix, notice its still losing coolant, no overheating ( going by my temp gauge) no coolant in my oil, no heavy white smoke so I'm stumped and also my fan doesn't turn on with the heater but does with a/c any help would be greatly appreciated

research (search) for bleeding the cooling system. It is a long process.

You could always install your own relay switch for the fans. It's not hard to do and is very cheap.

Did you plug in your radiator fans when you re-installed the new radiator, Sounds stupid, but I did it once... Also sometimes it takes a few tries to burp the system.

the best way I found to add coolant is to add coolant to the block through the upper hose till full, then add coolant to the radiator through that same hose, and then through the turbo reservoir.
I didn't have to burp at all doing it that way.

that being said. you probably just have air bubbles that are being worked out, that's why your coolant is appearing to disappear.

The fans will not turn on when you turn on the heater but will turn on anything that uses A/C like the defrost.

I've never really had trouble bleeding the stock system, (provided the thermostat was good and installed properly), but I did have issues like yours when I installed a Mishimoto radiator.

Like you, I never experienced an issue with overheating, but I did notice some coolant disappearing. I had a feeling air was still in the system, so I did the following:

-Opened the coolant reservoir by the turbo and stuck a tall funnel in the top to catch overflow

-Turned the heater on full blast

-Started the car and let it get to FULL operating temperature, revving it up a bit once it was fully warmed up. Once the thermostat was open, I got out and "burped" the upper and lower radiator hoses as well.

I saw a lot of small bubbles for quite a while... for a moment I was paranoid I might have a leaking head gasket. But then, after about 30-45 minutes, it stopped.

After that, I pulled the funnel, replaced the cap, and have used next to zero coolant since. All I can figure is that it's a big radiator, and as a result getting ALL of the air out is a bit more difficult.

Hopefully you are dealing with pretty much the same issue.

Start with burping the system. Sometimes it helps it go faster if you raise the front end. Then check your thermostat and make sure its opening. You just boil a pot of water,then put the thermostat in it and you will either see it open or wont. If it doesn't budge then you have got a bad thermostat. Also check your fan. Turn the heat full while its running when you're burping the system.

I agree, it sounds like you just haven't burped it fully. Has the car ever shown any signs of being overheated on the gauge?

When I do anything that requires changing coolant I run the car with a funnel in the upper res. and keep it running until the car gets up to temp and the fans cycle twice on their own, while the heat in the car is set on full, but keep the blower fan off. This can take quite awhile with a big rad, I would say it takes me around an hour generally, and I have a big 3 core aluminum rad.


The sensor that controls the fans is on the water pipe under the intake manifold, behind the alternator, just as an fyi.

I have a 2002 bugeye wagon and just replaced the radiator with a Koyo with no cap. I figured with one less cap there was less to break or leak. Plus thats how the car came. I had no problem getting air out of the system. First I ordered the Lisle 24610 spill free funnel. Amazon has it for $21. You can read about it in the cooling system FAQ thread.

There's a small vent hose that goes from the top of the radiator on the passenger side to the expansion tank. I disconnected it at the expansion tank and tied it to the hood prop so it was high enough coolant wouldn't flow out. Next I capped the expansion tank connection for this hose to keep coolant from flowing out while filling the system.

Using the spill-free funnel I then filled the system. Almost all the air trapped in the radiator went out the vent line tied to my hood prop. This eliminates the need to burp the upper radiator hose but go ahead and try it to make sure. I did.

Next I reconnected the vent hose from the radiator back to the expansion tank. If you skip this step you'll have a fountain when you turn on the engine. Ask me how I know.

I then started the engine and let it run until the top of the radiator was hot and the driver side cooling fan came on. I made sure the funnel had coolant in it. I had some bubbles but not many.

Next I shut the engine off and replaced the expansion tank cap and filled the overflow tank to the upper line. The few remaining bubbles worked themselves out the next time I drove it and were replaced with coolant from the overflow tank.

There is no need to turn on your heater since there are no heater valves in the cooling system. You need to be sure you put the thermostat in correctly if you replaced it. There's a small jiggle pin in the thermostat flange, it has to be at the top. It vents air out of your lower radiator hose when filling.

On Subarus with two caps, one on the expansion tank and one on the radiator, the lower pressure rated cap, 108 Kpa and with ears, goes on the expansion tank. The higher pressure one, 137 Kpa with no ears, goes on the radiator. The expansion tank is the highest point in the cooling system. This will make sure any air bubbles in your system will be vented out through the expansion tank cap. Having the caps reversed will means pressure increase when the engine warms up will vent coolant out instead of bubbles.

Its been almost a month and no coolant loss except a very little which is prolly due to the temp going from the 60s to the 30s thanks for all the help guys
