1992 240sx fastback KA24DE overheating!!!!! still...

[niemczykj]

my car used to overheat a lot before i bought it... i replaced the cylinder head over the past few months, and replaced a bunch of hoses and sensors...well now that its back together it still overheats!!....i replaced the thermostat and that didnt help... i have a hole in my overflow tank if that means anything..

i need help please i dont know what else to check... my radiator is good and there are no leaks from underneath...help please

I know you just replaced your head gasket but have you done a compression check? A leak in the head gasket can cause the coolant to get air and cause over heating. Did you resurface the head before you put a new head gasket on? Too much timing advance can also cause it to run hot. Does it only over heat on the street or does it also do it on the highway. If it only does it on the street your clutch fan might be on its way out.

the head was resurfaced, compression is good....it overheats driving on the street, i havent taken it on the highway yet...

it overheats quick...like 300yards of driving

Try and borrow someone else's clutch fan and see if it makes a difference. I'm not totally sure how you would go about testing your own just know that if it overheats on the street and not on the highway that usually means the radiator is not getting enough air.

my fans works fine....it blows hard...

Only other things I can think of are either there is air in the system, bad cap ,or bad water pump. Changing the cap and coolant is cheapest.

im gonna go get a cap now...the one i have now idk if its good.... while the car was running it started getting hot...so i shut it down.... when i popped the hood there was coolant all around the cap like it had gotten out or something... does that mean its bad/?

have you checked the water pump?
