M50 is overheating

[02stu]

I tried to drive my car back from midas today and it overheated. I'm using an m42 radiator but I think I have way to much antifreeze and not enough water. Is it possable to overheat from that alone?

[Mike B.]

Did you bleed the coolant system? Are the heater lines hooked up correctly?

[02stu]

the heater box is bypassed right now, I thought I would have this done before it got cold out, and I have bleed the system. It overheats right after the thermostat opens. The temp. gauge is also not working, but it appears to be hooked up properly. I don't have a fan though, is anyone running a m42 radiator w/out a fan?

Is it a new thermostat?

Get a fan tho, you will need it.

[bimmerboy570]

get the fan delete kit or build one yourself maby even a diffrent coolent if you do go the fan rout watch your radiator

[CarsSuck]

I think you may just not have enough cooling capacity with a radiator for a 4cylinder and no heater box and no fan.

What is a "fan delete kit"?

Thanks

fan delete kit= lower temp thermostat, lower aux fan switch, and redline water wetter, and a fancy nut to cover the waterpump threads hahaha

A fan delete kit involves the removal of the belt driven fan from your car, and switching to a lower temperature thermostat (80 instead of 88°C). This is to get rid of the parasitic losses associated with moving air.

I really see no point in that. the m20 fan fits and does almost too good of a job cooling with my rad (and it is an auto rad)

I can run an m20 fan on my m50? Thats good news, I can't believe there is room. With no fans and my m42 radiator with a 50/50 mix and no thermostat at all I can stay at the half way mark in traffic untill it gets to 70 degrees outside. with low humidity.

im running the m42 rad as well, i used to over heat but since i switched to the m20 80 degree tstat it has been staying cool...i still do plan to add water wetter and get a e-fan to help out come summer time.

But, it adds more parasitic losses moving less air with a less efficient type of energy.

HAHAHA. :finger:

Yes I know, there are losses associated with turning mechanical energy into electrical energy (alt), back to mechanical energy (fan motor).

I was just stating what the E36 crowd does to get 1 whp in isolated test conditions.

IMHO it's not really worth it. But I already installed an E36 radiator so I don't think the M20 fan's going to fit.
:curse:

1whp is within the margin of error of most dynos.

The e36 radiator is identical to the e30 one. I am running one also. So was ///Mpressive and he found room for a mechanical fan.
