I have a 93 honda prelude with a jdm h22a i just got it back from the shop for over heating too much and kno it just barely heats up one bar above, as soon as i turn on the heat it goes down. im gonna try this product in my anti freeze that lowers the temp 16%, is there any thing that i could do?

 

umm that **** is wierd..is you sender unit hooked up right. i know if its not hooked up and touching something it will be all over the place

 

See if your fans are working, check the engine and ECU grounds, check the thermostat, bleed the cooling system, etc...

 

I believe that it is, so ur saying that cooliing stuff in ur anti freeze is weird? another thing is that as soon as i turn the engine of from reading a little hot and turn it back on its back to normal...

 

my fans are working my ecu seems fine, i just got the damn thing back today and it was running perfect the fans would come on even with out the key in it as normal but now they dont come on after i take off the key..

Ok, I'm sure the ECU is fine, but bad/loose grounds can cause the temp gauge to act wierd.

 

ok i will test all of my connection tomorrow

 

There's a main ECU ground right on the underside of the thermostat housing (where the longer lower radiator hose goes into the engine), also check the tranny ground and valve cover ground. Basically just unbolt and sand down the mounting surfaces with fine sandpaper so the connection is good.
