Hey guys I noticed the other day my 2003 zx2 took a little while to warm up. So didn't think anything about it. Of course when they start doing this I know there Is a problem. So i went bought a thermostat. Changed it no change. Filled back up with 50/50. Checked oil no coolant. But sense it does this fans dont kick on unless I turn heat on. Changed 40A fuse cause it was starting to look rough. No difference. Still stays on cool side till it's hot almost over heating I would say any ideas?
