Just finished replacing my radiator (was cracked) added a magnefine transmission filter and installed B&M 70264 transmission cooler on my 97 honda civic AT.

I was also planning on putting in a Mishimoto Fan Switch and a Low Temp Thermostat.

My problem is I couldn't get the thermostat housing open. I was able to remove 2 of the 3 screws.

I believe the 3rd screw is rounded so the ratchet doesn't have a secure grip around it to turn it.

What can I do to remove this bolt and how do you remove the thermostat housing after that? I was trying to move it but it seemed not to budge.

QUESTION 1: Any tips on removing this stuck 3rd trouble bolt???

I would like to install my fan switch and thermostat for better cooling.

QUESTION 2: How to wire my new go autoworks radiator slim fan to the stock connections?

I noticed the connectors aren't the same as the stock connectors. I'm guessing, I will have to cut the wires while leaving some sticking out? What tool do I use for this.

I'm suppose to connect the black and black and the blue and/or green wires together. Just as long as black is connected to black?

Wrap/tie the cords together and put duck tape? or a connector? what's the best way to attach these two wires?

Great.

Why?
Is the thermostat bad?
Is the fan switch bad?

Is the engine stock, and do you think you know more than the engineers that built it?
Is the engine modified, and with what mods? Does it NEED to run cooler than stock?
Do you know what negative effects there are with an engine that runs too cold?

Good.
It's trying to tell you something.

Yeah.
Reinstall the 2 bolts you managed to remove.
Get a real service manual.



Adding cooling capacity is one thing, and that's ok. May be overkill, but ok.

Overcooling is NOT ok unless the engine is heavily modified and you are specifically directed to do this by the builders.
Refer to my other snide comments above.

Cut
Splice
Solder
Heat shrink and seal.

Maybe, maybe not.
Wire colors don't matter now.
Airflow direction matters now.
You should know how a fan blows.
You need to know how the original blew.
You need to make the new one do exactly the same thing as the old one.

You have a 50/50 chance of getting it right or wrong.
You should figure out how to make the fan run on a cold engine for testing, before you overheat and trash the engine trying to see if it worked.

Wow.
Am I harsh this morning or what?



/Yeah, I got issues.

How many bolts hold this thermostat together? Which bolt is stuck?

I think the thermostat and switch could be bad. It's still the stock one. I drive the car hard so I want it to be sufficent cooling. I usually always make sure I have been driving for about 10 minutes before I drive the car rough.

The car is stock. Engine is not modified. Yes, I know what negative effects happen when the engine runs cold. Has about 151,000 miles.

There are 3 bolts that hold it together. 1 on top right. 2 on left side.

I was able to get the 1 top and 1st left side one out easily.

The bottom left side #18 is the one that is stuck.

I think my thermostat is stuck because it never goes up at all. Even when my radiator cracked, nothing happened.

Easy enough to test, with the right tools.

I drive the car hard so I want it to be sufficent cooling.

Larger capacity radiator is plenty sufficient for a stock engine.
Heck, the stock setup was sufficient.
Doesn't matter how hard you drive it.
Until something doesn't work right.

Good, don't wanna be hard on a cold engine.

And you are willing to live with the negative effects of running cold?

There are 3 bolts that hold it together. 1 on top right. 2 on left side. 2 hold it together. The third one is for ground wires.

I was able to get the 1 top and 1st left side one out easily.

The bottom left side #18 is the one that is stuck.
Put the other one back in before jacking on the stuck one.Try a little penetrating oil
a little heat
While turning it.

Twist sockets are incredible tools, if there is enough meat left for it to grab on to:

beating on the head of the bolt
beating on the side of the housing where the threads are
slice a slot in the head of the bolt for a screwdriver
chop the head off, slide the housing off, then deal with the stuck bolt

How about a bad temp sender or gauge
how about it never lost enough coolant to get hot
You can waste a lot of money firing the parts cannon and never fix it.

All this stuff can be checked, much of it quite easily.
Test, don't guess.

^A little rough yes but true. You will spend thousands throwing random parts at problems that could be so simple as a temp sensor.
