I am unsure about what's happening. The car runs fine, but today and just today (for now) the car's temp needle went to 2/3 HOT. I quickly turned on heat and it went down. Also, it seems that it's taking awfully long for the heater to get warm. I have my fan wired to a switch (which I have on most of the time.)

Is this my thermostat or am I missing something?

 

 

when was the last time you had the cooling system flushed? Fan spins the right way?

 

Fan is working fine...I've never flushed my system in two years. Can this be related to the sudden coldness? I heard a thermostat can stick...

 

Might as well change it, a thermostat is only like 5$ from pepboys or autozone...

 

Do both. Change the thermostat and flush the cooling system.

 

I'm about to go pick up a thermostat for my 93 Cx. Can someone tell me how I change this part out? Pics of this would be great! I am going to flush the coolant as well.

Yesterday, my car was idleing like $hit at red lights and the temp. gauge is going up and down like a roller coaster.

Thanks!

 

While your at the parts store, pick up a Haynes. I think they're about $15. It should cover the thermostat install. After that if you want to tackle bigger things get a Helms. Helminc.com I think they're about $66 shipped.

 

I'm about to ditch that engine for a GSR so I'll have to skip the manual. I found intsrucs on a different thread. The thermostat is located in the lower radiator hose where it connects to the engine.

I am thinking about rebuliding the Cx engine so maybe I'll pick up a Helms for it after I do the GSR swap. Can you believe I am actually going to try and do this swap with the little knowledge I have .....but, I'll have my pops there who knows a good bit, a couple of friends, and of course the boards
