Hi guys im new to Honda tech my names Marcus. I've recently bought my first car (1998 Civic EX coupe) and its been overheating after driving it for about a mile or two. I changed the thermistat thinking it would fix it but it diddnt. My fluid boils and shouts out of my reservoir while im driving. In the morning i check it and look at my hoes and there sucked in like theres no coolant in my radiator. i check my coolant bottle and theres coolant in there as well. I have no leaks of coolant or anything. My fan works but it seems like it only turns on when the gauge is nearly at the H and not on the 3/4 mark. I also did a compression test on my radiator and it loses compression aswell. One of my coworkers tells me i have a blown head gasket but i dont have coolant mixing with my oil. It feels like i have lose of power and my engine idles rough as well. I dont know what to do because its annoying to keep stopping and i dont want to go and sell it either. Please Help

 

Pressurize the coolant system with the spark plugs out. Shine a flashlight into each cylinder and you will likely see coolant entering one of the cylinders.

This means exactly what your buddy said, a head gasket job is in order. And depending on how badly and how many times the car has over heated will depend on if there is a warped head or block and if it's even repairable.

Might need a motor swap if it's bad enough.

 

Oh yeah I forgot to mention that I checked my spark plugs for wetness and the dry as well >< but I'll still do that test though
