Another overheating problem help plzzz

[T3X_S13]

First off I serched n serched for answers to my problem.Well I have a s13 sr20det and its been overheating.At first I thought it was the ka rad goin bad so I replaced it with a cx racing rad with new fans I also changed the coolant and blead the system.Wen I have the car ideling its okay but once I get it on the road 10 min later it starts to heat up and the upper rad hose gets real hard??Also doesn't leak any coolant.Could the water pump be goin out or maybe the headgasket is blown it dosent smoke white out the exhaust?I only had the car for about a month now. Thanks

you can just use a crossover hose....

my freind had an overheating problem like this, turns out he was using old nasty hoses and the buildup in them was breaking off and clogging stuff up.

Check your thermostat and radiator cap.

[T3X_S13]

No termostat,I'm pretty sure the cap is good...

If you don't have a t-stat i hope it isn't your daily.

Flush the radiator/engine, check for air bubbles in the radiator when idleing, check thermostat.

I've had multiple problems with cars in the past overheating (mostly because they are old, and the previous owner abused the hell out of them.)

If the upper hose is hot and the lower is cold, then that means you are not getting good circulation throughout the coolant system, and would easily point to engine overheating after it gets to normal operating temperature.

If you do have air bubbles in your radiator at idle, then your headgasket might be at fault, but i would try the other routes first, because they are cheaper, easier, and very well could be the cause of your problems.

Keep us updated.

hehe fat and hard....

hot upper cold lower could mean air in the system / no flow

Okay I was working on it 2day.The car dosent overheat at idle it stays at normal temp even wen I rev it and stuff but wen I get it on the road 5mins later the radiator hose gets real fat upper and lower but don't overheat right away takes a couple of more mins am totally stumped on this one I even changed the radiator cap now . Am really hoping it ain't the headgasket.
