Of preshure.I think the coolent lines is messed up or somthing.its got a brand new head gasket.arp head studds.there is a extra small water nipple off of the water neck and there is anouther one off the thurmo housing.plz help me I need this thing running cause my boosted hatch got stollen and this is my only ride.I like need a coolent diagram for a ls vtec setup.its a b16 head with b18 block.thanks

 

Did you burp the coolant system yet?

 

Iv like tried a little to bleed it and everything but like if i drive it for 20 mins and cut it off you can hear like water driping from the iacv hose.its like building up so much preshur its trying to find any where to come out.and the rad hoses are realy realy hard.its got me stumped.I know I'm proly not giving the best details but its making me mad lol.why do peaple got to steal cars I just don't get it

 

what timing belt/water pump you using?

are you sure a iacv hose or iacv gasket isnt bad ?

 

Ok so I changed some hoses around and its running a lot better.it only runs bad if I'm in trafic and then it starts idle surging.and then it feals like the car is lagging it like bairly has pawer then it kicks back in agin.and if I pop the hood the hose from the back water pipe to the iacv has a lot of preshur its almost like its not letting it circulate through it.could it be bad or something,.its like when it gets warmed up the throttle response is horable.what you guys think it could be.would if be worth trying to change the iacv
