Car overheats at idle!!
 

Im having a problem with my d16z6 in my crx with it overheating when I drive it and when its just there idling. I also find it instresting that the cooling system does not develope pressure as the temperature rises to 200 and up. I can remove the cap and nothing. I look in the radiator and I do see coolant moving through the radiator. Ive gon with the eg radiator with an aftermarket fan. The downpipe sits kinda close to the radiator , but would it have that big an affect on the overheating. Im using the manifold sold by donald125 on the forsale section with a t3/t4 turbo running uberdata. I had changed the headgasket hoping this would fix the problem but nothing, now I did not have the head resurfaced, and dont know if this is the culprit. Is there something I am missing? The car is also not running a thermostat and I have made some vents on the front of the hood to aid in fresh air to come in the engine bay. Anyone have this problem help me out , im almost completely fed up with this car that wont behave. Thanks in advance. :D

get a thermostat in it you dumb nog. It's designed to have a t-stat. Plus make sure you fan is kicking on, and then buy a new radiator cap for shits and giggles.
Also are you running 50/50 mixture?

plus i hope you checked the head to make sure it wasn't warped too badly

how long does it take to over heat sounds like a stuck t stat ,,,

Put in a thermostat.

If that fails then I'd put money on your radiator leaking through the end tanks. WTF nig, don't be noobish.

if u have a half rad u shuld have a block off plate for the other side to help run the air through the rad

also is your fan running?
if it is running make sure its going fast enuff

Alright I'll try to put a thermostat in it, as for the radiator leaking it is brand spanking new , dont think it could be leaking since the car when driven or idling is never low on coolant. Fan is running and even tried to have it in a push setup for shits to see if that would make a difference. Im not running running a 50/50, instead I was running the water wetter with about 30% antifreeze the rest water. The radiator car is also new , but I have had new stuff bad from the store before. Would it be worth a try to remove my intercooler to see if that works. The more and more I think about the more I am leaning towards taking the head off and starting from scratch. As far as the fan is concerned its a fan they sell at american autoparts its a 10" fan and fits nicely on the radiator. And also do you recommend the insulating the turbo with a blanket and wrapping the exhaust with some heat wrap? I wish I had a five gas analyzer to sniff the radiator for hydorcarbons. Im only home for about 12 days of the month so im trying to brain storm to have a plan when I make it home . Thanks again :1

you can try a cylinder leakage tester and then look for air bubbles in the coolant. And then with the 8G's you save from not buying a 5 gas, you can just pay me O0

Thats probably what ill do , but I cant recreate the pressures created during combustion with the tester. Im just going to change out the gasket. But the CLT will help if the gasket if damaged that badly. Thanks for the imput.

Re: Car overheats at idle!! UPDATE!
 

Took the head off and had it checked for flatness and checked out . Turns out I had two bent exhaust valves, the guy at the machine shop said the head really wasnt badly warped. Put some ARP headstuds on and put the thermostat on. Actually had some pressure but I started losing coolant. Next day there was a puddle by my balancer of coolant. Waterpump took a crap. Its going to have to wait till I get back in two weeks to change it out.

well your wp may have been the start of the problem
