i have a 88 hatch with a b18a1 swap and it runs good when its cold and crappy when it get warm i am having a problem with overheating also i have replaced thermostat and upper radiator hose but it still gets hot. and sometimes then engine will baugg down and act like it doesnt want to go and i do not know what is wrong any help would be great thanks

 

is your fan working?

 

yeah i got it working

 

an d15 will help that out... jk

 

does the gauge read as if it were "over heating" if it were over heating the coolant would overflow in your resovor box... if it dont do that i dont think your gauge is correct... so as for checking your gauge i dont really know how to check that...
