Having overheating problems
 

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

Re: Having overheating problems
 

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.

Re: Having overheating problems
 

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.

Re: Having overheating problems
 

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

Re: Having overheating problems
 

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

Re: Having overheating problems
 

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.

Re: Having overheating problems
 

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

Re: Having overheating problems
 

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.

Re: Having overheating problems
 

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?

Re: Having overheating problems
 

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

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

Re: Having overheating problems
 

Water pump can't go the wrong way. If the blades on those are stamped steel, I've seen pumps with a nub where the fins rusted away. check the water pump.

Re: Having overheating problems
 

the only thing is that the water pump is brand new!?!?!?

Re: Having overheating problems
 

The pump cant go the wrong way, unless somehow your engine is running the wrong way :). What makes you think that its overheating? Just the gauge?

Re: Having overheating problems
 

So can you see coolant flowing with the engine running and the cap off or not really? Check the actual coolant temp in a log with Link.

Re: Having overheating problems
 

I have said it was the water pump since day one. I hope im wrong chris but I think map should replace it for free since you have just been buying tons of shit from them to try and fix your over heating problem.

Re: Having overheating problems
 

Well I just got off the phone with Alex from MAP and I'm dropping off the car tomorrow for them to look further into the hassle of overheating!

Re: Having overheating problems
 

I have ECMlink v3 and its set up so that when it gets to a certian temp then the check engine light goes on and when that happens the gauge is about 3/4 of the way to hot!

I cant really tell if its flowing or not because when I turn the car on the coolent level goes up and sits level with the mouth and just kinda vibrates... if that makes sense? I'm thinking that there is some sort of restriction that is causing it to overheat.

Re: Having overheating problems
 

And spent alot of money!

I got the mishimoto radiator
F.A.L fan shroud

Then the fan shroud wouldnt fit so I ordered a MAP 02 housing and got that coated which was over 300 dollars

F.A.L fans still wouldn't fit so I bought 2 12" mishimoto slim fans

Got them to both run at the same time, and at all times and alot of money on coolent taking the radiator in and out so many times its just F-in rediculous!

Re: Having overheating problems
 

Hope everything works out for you and doesnt cost you any more money. You have spent enough

That is my thread with all the crap I had tried on my car. Might be worth scouring through quickly.

Re: Having overheating problems
 

Could it be a gasket restricting the water flow possibly on the pump or somewhere where coolant flows but not enough to cool the car?

Re: Having overheating problems
 

That is another thing that I was thinking and brought to maps attention...

Re: Having overheating problems
 

Ok so MAP called me and they found a small leak right below the thermastat housing and fixed that... also they said my 2 fans running off of the one wire isnt sufficient enough..
SO, They need to weld a 90 degree elbow onto the turbo, then they need to redo the bottom intercooler piping so that a factory fan will fit on the passenger side. and move 1 of the mishimoto fans over to the drivers side.. Then rewire the fans so that they are both running off of there own seperate power source.. 1 off of regular heat and 1 off of the a/c wires... $230!!!!!!!!! I wouldn't think that I should have to pay for anything really since I paid over 7k on the motor and then over 1k on just trying to keep my engine cool.. We will see what happens though....

Re: Having overheating problems
 

I hope this resolves the issue.

Re: Having overheating problems
 

I would say they try this and if it fixes it, then pay them and if it doesnt then they should not charge for things they are just trying. Ya I realize that they are a business, but when you pay for a engine swap, you expect it to work correctly when you take possesion of it. You have had tons of problems and you have not even gotten a deal on tuning.... Something needs to happen, its not even my car and it pisses me off.

Re: Having overheating problems
 

Mike pretty much feels like i do but is expressing himself more.. I am pissed off about it and hope that this fix's my problem that I have had for the past 2 months since I got the car back from them..

Re: Having overheating problems
 

Thanks Brandon I aswell hope all goes well and gets resolved.

Re: Having overheating problems
 

Chris,

As we have said MANY times if something that we did is causing this issue you will not be charged to rectify it. On the other hand, your car is approaching 15 years old and there are many components that we did not touch / replace on your build. You paid us to replace your short block, assemble it into a long block, and get the car running which we have. If you would like us to rectify this cooling system issue we will do everything in our power to do so, but I simply can't understand why you think we should do this work for free if it has nothing to do with the work that we performed? Also, the suggestions we made in regards to replacing the radiator and fans were exactly that, suggestions. When trying to diagnose an issue like this there is no way we can be 100% certain that our suggestion will rectify the problem. With that said, regardless of whether or not moving and rewiring the fans rectifies the situation we will need to be compensated for our time. If there is any issue with this please contact me immediately so that we can stop working on your car.

Re: Having overheating problems
 

how much boost u run to get them numbers?

Re: Having overheating problems
 

29 psi

Re: Having overheating problems
 

Called and talked to Chris and everything is being worked out with no hard feelings and I will find out probably tomorrow if this will solve the overheating problem...

Re: Having overheating problems
 

Why is the power so low? Stock cams? Mitsu exhaust housing holding it back?

Re: Having overheating problems
 

I'm not really sure myself... I was expecting more. I have bc272 and everything is built.. possibly because of the mitsu housing.

Re: Having overheating problems
 

Got my car back from MAP today and as for now I couldn't be happier with it! However I need to put my thermastat back in because I cant even get up to running temp without one.. This is no big deal. I'm just glad I can get from point A to point B without getting hot.

So special thanks to John at MAP and also to MAP for there help and support on getting my issue fixed!

They ended up having to weld a 90 degree elbow onto the turbo and to push the intercooler piping out of the way far enough to fit a stock fan on the passenger side and then rewired the hole thing so everything is perfect!

Re: Having overheating problems
 

car feels really quick. I got a ride in it today, only thing is its a little laggy.

Re: Having overheating problems
 

Good to hear.

Re: Having overheating problems
 

Glad it's worked out.

Re: Having overheating problems
 

I'm glad to hear we were able to resolve your issues sir, and I hope you didn't take my comments above the wrong way. We run into this situation all too often and it is frustrating for both parties, but I like to think we have a pretty good idea of what we're doing here ;)

Re: Having overheating problems
 

Yes, I am very happy with my car. I have been driving it all day and still no overheating problems! However like I said I cant quite get it to regular running temp so I think I'm leaning twards putting my 180 degree thermastat back in and drill 2 holes in it. Hope it makes warming up easier..
