sup all..
i have had this over heating problem for about 5 mounths now
heres the prob. when i drive the car on the street it is ok..temp about 185 to 195 some times 198 depending on time of day

as soon as i get on the freeway the car slowly rises in temp..from 195 or so up and up so about 230 the longer i drive the higher it gets . if i turn the heater on full it will stable the temp ..so if the temp is at say 210 it will say 210 and slowly come down or if it's like 198 or 199 it will stay even when im on the freeway for more than 30mins

what iv done to try and fix this is. i have changed the head gasket a few times ..had the head resurfed, and checked ..flushed the system many times ..i have water and weterwater ,, no thurmastat, have presertested the system up to 20lbs and no leaks. i ave a fel fan thats blowing the right way. iv check the water pump and even ran the car with the up hose off see if the water is being pushed and all is ok ..i just cant figure this out plz if any one has idea feel free to say thx alot guys

set up
fullybuilt 84mm sleeve
topmount 35r

 

Sounds to me like your radiator is too small/inefficient. and running without a thermostat wont help anything, it will actually make things worse.

 

What chassis are you running? what radiator? give more info on the setup. Generally if your running cool on the street and hot on the highway and you've done the simple things then you have an air flow problem to the radiator. The car should be able to run cool on the highway without the rad fan running.

post pics and what the setup is. Have you wrapped the manifold ? are you running a turbo blanket on the turbine housing or at least have it hpc coated ? sounds like its due to heatsoak and poor air flow

 

this sounds like the typical honda, lack of airflow issue. at higher rpms the radiator/fan cant keep up especially in the summer.

pull the bumper and see what happens. if that helps then you will need to find a way to get more air to the rad at all times

 

here are a few pics of the setup

 

Definitely an airflow issue. Not only are you losing a lot of airflow by having your radiator diagonal to the flow, but you have a ton of crap behind it that is blocking a lot of airflow.

 

First and most obvious is the radiator on the diagnal. Secondly get a blanket for that turbine housing, then wrap your topmount and double wrap the DP if you have to. all those things should drastically reduce underhood temps and the radiator being straight will allow more air flwo to it. then go from there. also spacing the hood in the back allows the heat to escape the engine bay and helps out somewhat

 

if i put the radiator back to thr front and not diagnal, the down pipe sit on it. it has already started to melt the fel fan and u can see where the wrap started to ripe from rubing on the radiator ...but i can try puting it back

 

well you can easily see that the problem is the angled radiator. you will just have to find a way to make it straight since you said it hits the dp. IDK but maybe you will have to bend the frame and manuver it in there somehow.

 

Put a "pusher" fan in front of the radiator if you need the extra room behind the radiator. It doesn't work "as well" as a pulling fan but compromises have to be made.

 

or you can leave the radiator the way it is and direct all the air to the radiator with sheet metal
