immediately after mounting the turbo and getting everything setup and running good, i noticed my temp gauge went up to about 3/4 the way up and then after a few seconds came back down......i didnt think much of it at first - figured it was just the thermostat being a little slow to figuring out how hot the water really was...

but after about 40 minutes of driving its unrecoverable - the heat will just not drop and will continue to go up....i even blasted the heater to try using it to disipate some of the heat, and nothing.... finally i just have to turn off the car, and leave it for a few hours to cool down.

i have a fluidyne radiator (smaller civic style) and fal fan that runs full time.

taking the thermostat out just makes it worst and only lasts about 10 minutes before it reaches an unrecoverable heat.

ive tried both a 190 and 170 degree, and they both ultimately end up overheating also.

i dont drive hardcore or all aggressive, and to even see if it was cuz of the turbo or not, i cruised real easy on the highway for about 15 minutes in vacuum, got off on the next exit, and boom, at the light it started to creep up.

the motor only has 2,000 miles on it, and waterpump was brand new honda oem.
its possible the pump may be going out - but very unlikely.

at this point im stumped. any suggestions guys>?

ps- there are no kinks or restrictions in the hoses, and there is no air in the system, ive bleed it several times to confirm.

 

Either you have a air pocket in the coling system or you have a blown head gasket, that is just barely seeping somewhere.
do a compression test to check.

Here are a few suggestions for you I don't know if you have tried them already but its worth a shot...

1. When the car is warm feel both the top and bottom coolant line and see if there is a difference in temp the top should be hotter than the bottom pipe.

2. Take your oil cap off and see if there is a milky colored residue in the bottom of the oil cap if there is your headgasket is blown.

3. Have the cooling system professionally flushed, basicly what they do is suck all of the air out of the cooling system and than fill it up with coolant.

I hope I was of some help for you...

busted thermostat? coincidence? I have a B18C turboed, and i use the small EG rad. no problems even on long drives.

weird

 

I would say the easiest thing to do is take the radiator cap off and let it idle until the thermostat opens, if it starts to bubble uncontrolable out and kinda pop then there is a headgasket leak with getting air in the system. Or you could see if the hoses are pressurized and after driving the car for a little while. Just check and see if the hoses are blowing up,expanding. Let us know if this helps.

Note:Unplug the fan or set it back to stock where it comes on after the thermostat opens or you will wait 30mins or so.

 

thanks for the input guys, lemmi update u on a new theory ive got.

ever since i put the turbo on - i had to drain out almost a quart of oil, because my moroso oil pan's turbo tap sits like half way down on the pan, so i had to let it drain to the point that it would not back up into the turbo return....

i checked the stock dip stick and its like REAL LOW...but i figured the pan was engineered correctly and that with all the extra quarts it takes would make up for what i had to let out...

this was done at the exact same time i put the turbo on - and its ever since its been over heating.

my oil light has flashed a couple times on different occasions and needless to say, scares me to see it come on.

im going to put a stock oil pan on tonight, tap it high, and fill the oil to the correct levels - i'd almost bet money thats what it is.

if u think im on the right path with my thinking here, let me know.

 

when i put my turbo on last year my car over heated alot. for 3 months i had to put up with the heat blasting when it was 100 degrees out side or if i flew up a hill. then i drained my cooling system out ran a hose through it and filled the radiator with 2 bottles of redline water wetter and the rest of the way with water and put a new thermstat in it since my swap didnt have one in it for some reason. after that it would over heat once in a while but not that bad. but it did turn out after i took my head off last winter my gasket looked like it was blown . but the water wetter sure did help alot.

 

lots of people have been there and done that.

its your HG man, fix it asap.

 

thanks for all the input guys, i figured out what it was....

the radiator cap was sucking in air once the coolant heated up.

so i would purge it air tight, and then 40 minutes later, was saturated with air...

did a pressure test on the coolant system, and it held solid for half an hour.
put on a new radiator cap, and its worked great ever since.

thanks

 

What about the tap being so low? Has anyone else heard of this or talked to moroso about it? I got a buddy whos turbo setup ill be helping install and he was planning on getting that pan. If it will be a problem I would like to know before the motor is done. Thanks

 

There was a thread on this elsewhere. It doesn't matter where the tap is. The only important thing are the fluid levels. The oil level in the pan must be lower than the oil source in the center bearing. Nothing else matters. A Fluid Dynamics course clears up that misconception...

 

Yeah, I can understand that, I was just thinking that since the oil supposivly comes out of the turbo as a frothlike substance instead of just normal liquid that the froth may back up all the way to the turbo easier if its not allowed to spill on top of the oil.
