Turbo d16 Overheating, Need some help
 

I just finished my set-up on my civic wagon. Unfortunately, the engine is supposedly over heating.

Attachment 24031

I am using an autometer temperature sensor because my OEM sensor stopped working after the swap. The gauge will slowly creep to <250F however the coolant is not boiling. I can take the radiator cap off with very little pressure.


The top radiator hose is hot and the bottom radiator hose is very warm; too warm to hold onto for more than five
seconds. I am using a dual core aluminum radiator. I am currently using a thermostat. I am running 50/50 pre-diluted antifreeze.

Could this be a warped head? Could this be just a lack of air fplw through the radiator being that the intercooler/ bumper is now blocking it. Could running the radiator fan constantly solve this problem? Please give me some feedback. I am a bit lost.

Thanks

do you know how to purge the air from the cooling system? im not trying to be an ass, but that can cause lots of headaches

Re: Turbo d16 Overheating, Need some help
 

I believe that the purge is on the front housing connected to the top radiator hose. I have not bled that but I Have run the car without the radiator cap on. I am pretty positive that there are no air pockets in the lines. I am not noticing any fluctuation in the gauge and the heater is consistently blowing hot.

are there any kinks or section of colapsed hose in the lower hose? that will do it too

Re: Turbo d16 Overheating, Need some help
 

No. I am actually running slighly larger diameter hose because of the larger radiator oulets. All hoses are straight and unkinked. The system seems to flow well.

What would be the symptoms of a warped head?

Re: Turbo d16 Overheating, Need some help
 

what thormastat you running ??



is you fan kicking on ?




you have to bleed the coolant system, you cant assume it ok ya know

Re: Turbo d16 Overheating, Need some help
 

if you have a warped head you would be losing coolant either burning it or going into the oil and if you are burning it most of the time your car will idle funny

Re: Turbo d16 Overheating, Need some help
 

Is that an ebay radiator? Because I had endless problems with the ebay radiator I used. Maybe a weird design or something, but it would build up pressure in the system until you were blowing off rad hoses, even after swapping the chinaking rad cap for an oem style one.

Re: Turbo d16 Overheating, Need some help
 

I don't remember if the fan was kicking on or not. I will try to bleed the coolant through the bleeder and hopefully that will help.

Car Idles very nicely. Oil is very clean. Coolant still glow green.

I am using an ebay radiator. I figured that no-one could screw up a radiator. There is no build-up of pressure in the system (i dont think). I am not using an oem radiator cap.

IAny more advice is welcome. Thanks so far; very helpfull tips that I will try this weekend.

that sounds like a winner to me. those slant-eyes may win the welding competitions almost every year, but they can't mass produce for ----.

Re: Turbo d16 Overheating, Need some help
 

Have you tried driving around without boosting to see if it stays at an ok temp?

That happened to me a while back, and as soon as I would boost a couple times the temp gauge would go up. A set of ARP head studs and a new headgasket fixed the problem.

Re: Turbo d16 Overheating, Need some help
 

No/little pressure in a hot radiator is your problem.

- bad cap
- bad headgasket

Re: Turbo d16 Overheating, Need some help
 

I would do a compression test to see if there is any obvious head gasket problem.

I might also suspect the water temp gauge is bad. If you can, hook your OEM gauge back up to see if it reads high or normal.

I don't quite understand how at 250 degrees you arent getting any boiling.

Re: Turbo d16 Overheating, Need some help
 

nothing wrong with those rads, i run one with a shitty cap and never had a problem

Re: Turbo d16 Overheating, Need some help
 

I'd LOVE to get my OEM Temperature Sensor working again. If anyone has had some experience with troubleshooting them, PLEASE let me know. I really hate having extra gauges in my car, especially autometer.

I changed out the actual temperature sensor with another one I had. It did nothing. I have the autometer hooked up to that sensor directly. I checked all fuses to my OEM temp sensor but didn't find ay blown fuses. Does anyone know where the fuse is for the Temp sensor because I only checked under the steering wheel.

If anyone can shed some light on fixing my OEM temp sensor, I'd be a very happy man. I trust the OEM honda temp sensor over any after market sensor any day.

Thanks

One wire female butt connector under the dist cap, goes to the one prong sensor. If you ground the wire the gauge goes full hot - this will allow you to troubleshoot the wiring/gauge side of things. After that, swap in another sending unit from any 88+ Honduh and you're good to go.

Re: Turbo d16 Overheating, Need some help
 

coolant can get well over 210F without boiling because pressure its under increases its boiling point. by opening the cap and releasing any pressure that is in there while its hot is a bad idea, 1. hot water can shoot out and burn the ---- out of you, and 2. if the water temp is over 210 it will then boil. If you take off the rad. cap when the coolant is hot (not that I suggest it) there should be some pressure under the cap. Make sure you're fan is working that will def. cause it to overheat, i've seen people destroy motors because of somthing as simple as a 10 cent fuse had blown causing the fan to stop and the motor overheating.

Re: Turbo d16 Overheating, Need some help
 

wait your running a honda sensor with a auto meter guage ?

Re: Turbo d16 Overheating, Need some help
 

^^^^^^^^^^^^^^^^^^^^^^

Yes. I am using the OEM honda temperature sensor connected directly to the Autometer tamperature Gauge. Is this not the right way to do it?
???

Re: Turbo d16 Overheating, Need some help
 

holy ----. thats probobly your problem. i cant imagine they are calibrated the same

Re: Turbo d16 Overheating, Need some help
 

How do I solv this problem? Is there a different sensor I need to buy? I really feel in the dark ont his one... :S

Thanks

Re: Turbo d16 Overheating, Need some help
 

Connect the lead to the OEM temp gauge.

Re: Turbo d16 Overheating, Need some help
 

???

It is already connected to the OEM temp gauge. This is giveing a high temperaturen reading. I did not receive an after market sensor with the autometer gauge. I need to know if i need one/ where to find one and where to put it.

Thanks
