Where can i order a mugen thermastat?

My car hasnt overheated for a month but yesterday i was stuck in traffic for over an hour, next thing i know its almost at the red. It was pitch black and raining hard. I could hear the coolant fluids boiling into my resevoir jsut like it did a few months ago. Bottom hose was cold, top was hot. Only thing i can think of is that the thermastat didnt open up. Its a new thermastat but ive replaced everything else. Ive driven it every day for a month, 1 hour to school, 1 hour to work each day, never had any problems until last night while stuck in stop and go traffic.

Ive replaced

timing belt
water pump
radiator
radiator fan assembly
thermastat
hoses
spark plugs

and just about anything else that can be replaced under the hood, where is the bleeder valve located on a 99 jdm itr? "And no, its not on my radiator, my brother's bleeder is on his d16z6 sol is right on the block."

I checked the resevoir for fluids a few days ago and it was fine, checked after it boiled and there was none in the resevoir. But probably just ebcause it boiled all of it out. Oil is fine, been right on the full marker for a month, color is perfect. There is a possibility there were not enough fluids into the resevoir for the radiator to suck down, causing air in the system, causing the overheating, however i still think autozone sold me the wrong thermastat. The first 1 they sold me seized up like 2 days after i bought it. They dont have 1 for the Type r, they just have the 98 dohc vtec, i assume thats the gsr but they dont know for sure.

I would imagine King Motorsports would have them in stock.

 

they have them in stock

any oil in the coolant under the radiator cap? head gasket leaks or smoking from the exhaust?

 

didnt notice any oil in the resevoir, no noticible head leaks and exhaust is always smoking because its been raining for 3 days straight and its cold

how about the thermostat switch that tells the fans when to turn on? i know spoon(not sure about mugen) sale these to go with the cooler thermostat

 

have you ever flushed the coolant system? and does the fan actually turn on?

That's what I was thinking.
If you let the car warm up, does the fan go on?

 

i replaced the cts sensor as well

im going to go run my car for 30 minutes and make sure the fan is kicking on, when i first got the fan it wasnt working, maybe it went out

i dont know where the coolant bleeder valve is located, there isnt 1 on my radiator, and im not sure if they flushed it when they did my water pump/timing belt, saw them adding fluids and letting it run with the cap off, that was about it

"also, im usuing a 1.6L del sol si "sohc", radiator, with a junkyard fan assembly" Would the size of the radiator have anything to do with it? I was told the radiator would be just fine for dohc motor's."" Ill be back in a little while, gonna go run the car and see if the fan kicks on"

 

what about a cap...i'd try that first before getting a diff t-stat. If your t-stat was stuck closed the top hose wouldn't be hot. Sounds like you're bleeding pressure from the cap....

 

caps only like a month old as well

Not sure about the JDM R motor, but there is no bleeder on the block of B18C5s.

Hello, why was this not told before???

.

 

dual core civic radiators should be fine. thats not the issue (dual core, vs full itr style)

 

yes but i dont know if the radiator i am using is single or dual core, my original single core rad was stolen from gerage, when i ordered a replacement i asked for a dual core del sol vtec radiator, but the one they sent looks exactly like the radiator on my brothers sohc del sol, besides it is silver in color. I can take a pic if that would help.....

car has been at idle for aprox 30 minutes, it has been at normal operating temperature for about 10 mins, top hose is hot, bottom hose is hot, fan still has not kicked on yet

and the hoses are limp, they are hot from the fluids but they are pretty easy to sqeeze ect

*edit*

i just got out of the gerage, temp needle was mid way like it always is, fan never kicked on and the car ran for about 40 minutes at idle, both rad hoses were hot but limp, rad cap also hot, i noticed the overflow "coolant resevoir" actually gained more fluids instead of losing, i put my hand on the resevoir and it was making thumping noises, shut dow the car and removed the resevoir cap, the entire resevoir had filled with coolant and was boiling slightly. temp guage still read mid way....

now i gotta leave for work but without a car.......

obviously need a new fan assembly....still not sure what core my radiator is, single or dual, reciete says dual core but its the same size as my brothers sohc radiator from his del sol d16z6..........i would assume thermastat would be opening sense both hoses were hot "correct me if im wrong"........

common fellaz, help me fix this mess....need my car running

I really doubt the Thermistat is your problem. Even if your current one is working fine getting the mugen one will most likely not solve your over heating problem. I had a similar problem and got the mugen thermistat and have already gotten rid of it for the stock one again, it was more trouble that it was worth. It sounds like it is the fan or the radiator. I would also do what RTW DC2 said and check if there is oil in your coolant or vice versa.

*edit* well sounds like you solved your problem.

bump, 2 post up i explained in detail exactly what happens

 

3 posts up I said it looks like you solved your own problem, Your fan is not comming on.

 

you should figure out waht the problem is before you keep throwing parts at it

aw c'mon, the Black magic diagnosis always works. Try replacing your windhshield first.

I advise you to let the car idle from dead cold for 25 minutes with the radiator cap off. By then, the fan should of come on twice. If is doesnt, you have a electrical signal delivery prob/dead fan (hook up to electircal source and test/take a reading on the ecu to fan plug with a voltmeter). If in fact they do come on, and you see multiple bubbles and a thin rainbow "slick" developing in the coolant you have a blown head gasket. Dont be suprised if massive "burping" occurs in the first 10-15 minutes, thats air escaping. From there, you should of gathered enough info to make an educated decision on wheather it indeed is electrical or a mechanical failure (blown HG)

 

i already know my fan is dead, wont even spin when tapped to my battery directly.....picking up a new assembly tomarrow mourning...

im gonna run it w/cap off for a bit as well, hoses are not getting hard enough=lack of pressure= possibly bad rad cap or like you said blown head gasket from overheating
