Having overheating problems

[GsXtUrBo98]

I'm still overheating!!

I put spacers on the hood
Removed the thermastat " MAP recomended it "
Bought a mishimoto radiator and cap
running mostly water and some coolent
have 2 mishimoto 12 inch slim fans running at all times
REMOVED A/C
Put a heat sheild on my manifold and turbo

I had a 180 thermastat in there before I removed it, All of this has been happening since I got it back from map and I dont know what else i could do.... I think it could be my water pump because I will let the car run for 20 min at idle with a funnel and a radiator cap with a hole cut into it to suck in when needed and nothing, but when I turn the car off it bubbles and sucks some in.... the I do it again but at the end it doesnt suck any in... next step I put the cap on and move my car like 25ft then look again and my hose's are callapsed!! what could this be?

Any help would be greatly appreciated

Have you done a pressure test on the coolant system? Is coolant disappearing?

When you bleed the system with a funnel, so you see it flowing at all?

You shouldn't run without a thermostat or restrictor plate, that can cause all kind of problems and tuning annoyances including even worse overheating in some cases. Race cars that don't run a thermostat will still run a restrictor plate to allow the cooling system to be able to build pressure easier(water boils at high temps at high pressure) and to keep from causing any "short circuits" in the cooling system.

No pressure test yet want to do that today..
I do not see it flowing but there is a big funnel with fluid in it on my car..
I had a 180 thermistat in there before I took it out and it made no difference but people have been telling me to put it back in, so I may do that today aswell.

Should both of the hoses be pressureised? Top and bottom?

[Kracka]

Yes. Sounds like you've tried a lot of band-aids to cover a serious problem.

Im till scratching my head about this... I dont have a pressure tester and would need a new gasket to put in the thermastat its a 180 degree one that map put in before and maybe drill a hole into it.

Also, Is it legal to drive without a hood on your car?

I have in my 2.3 the same radiator as you, 190 thermostat, a 10" and 12" slim fans wired stock as pushers, no AC, and I never go over half way which would be under 200. Sounds like a water pump possibly.

Well I'm glad that someone else thinks the same thing that I do! I was just talking to my naighbor and he said that maybe the water pump is flowing the wrong way???? which could callapse the hoses, but I'm not sure that I believe him about that because the 1g's and 2g's both flow the same direction dont they?

^ What? That doesn't make any sense to me.

I'd say replace the water pump if you can't see any coolant flowing.
