my radiator for some reason blew up the top of it just block apart well i replaced the radiator now when i started my car it started reving realy high like 2000 rpm then i gave it a little gas and it started to jump up and down to like 1000 and then back up there is no check engine light on what could of coused this nead help ASAP im 2 hours from my house in morgantown and nead to go back on sunday

 

im ANYTHING but an expert....but my friend had the same kinda problem w/ his rx7 t2......its could just be your engines automatic warmup system, or it could be a faulty temerature sensor or water pump....

 

did you do a pressure test?

is the bypass clogged?

thermostat is working properly?

 

does anyone know if it would be safe to drive back the 2 hours with it like this becousei work at a honda dealership but i doutn hwant my car overheating and leaving me stranded in the middle of nowhere

 

no clue i just drov down to where i am and pulled in to park my car and as soon as i stoped and whent to turn off hte car the damn radiator just blew up iv fixed that but i have no clue what could of whent rong sence the time i drove up here to now i have nothing but a socket set that i luckily put in my car before i left

 

so the plastic end tank blown up?

 

the top plastic part blew up the radiator cap and a large chunk of plastic was laying on my intake

 

You need to get the air out of the passageways in the manifold. did you properly bleed the system?
try unplugging the fast idle valve and see if your idle will drop.

I think it's okay for you to drive it to the dealer, once the car is warmed up the fast idle should drop... given that there is coolant in there.

 

i didnt blead anyhting there realy wasnt much left in the radiator when i took off the drain plug. i just put water in the radiator for now but i tryed sqeazing the hoses to help pump it threw the lines

 

air bubbles in the coolant lines can cause a surging idle at times, particualrly after a radiator replacement

 

Quick question regarding bleeding the system, how long is normal to let the car idle with the radiator cap off? I have a surging idle much like the topic creator, and I filled up the radiator and let it idle for 5 minutes with the cap off, but when I look at the stream of anti-freeze going by, it still is bubbling at the top.

Very frustrating, maybe I have a leak somewhere allowing air into the system...?

 

last time i hada a aproblem with bubbles in the coolant it was a blown headgasket.

Do this. It's probably air in the cooling system. Bleed it...

you are not suppose to open the cap, the bleed valve is not the rad cap, it's located at the highest point in your cooling system, the cooling system is a pressureized unit, 1.1 bar of pressure that keep the boiling point down, way down.
