anyways…here’s my problem,
when i go outside in the morning…my car starts like a champ…if drive it for any amount of time and turn it off…it takes some cranking to start it…once it does start, it feels like it builds up the firing. once it starts, white smoke comes outta the exhaust (smeels like coolant) but if i drve away it will stop doing it.
today i got home from the store and turned my car off, only to have to start it right away cuz i was blocking someone in the driveway. it took some cranking to get it started again and when it did, it felt as if it had to build up firing power…like one cylinder at a time kinda. once it sarted alotta white smoke was coming from the exhaust and some came out from under the hood! so i popped the hood and hopped out to see where it was coming from and found this…
now besides the obvious fact that the hose is leaking and needs to be replaced…is there another problem?
i feel like coolant is just flowing through the iacv into the throttle body making the car hard to sart and also, once the car does start, getting burned and sent oout the exhaust in white smoke…
can i just bypass the iacv?
how would i do that?
i recently
did the timing belt
water pump
tensioner
oil change
put frest coolant (which is being burned)
new spark plugs
wires
cap
rotor
igniter
i don’t see how coolant would even be able to leave the iacv and get into the tb.
i guess anything is possible?
the iacv just opens/closes an air valve based on coolant temp to adjust the engine’s idle.
take 15 minutes, remove the hose, remove and check the iacv while the hose is off, clean around where the hose clamps to the engine and make sure that is where the water is actually coming from and not some unseen crack (or head gasket?). it could just be that the hose clamp isn’t in the right spot, or tight enough anymore.
while you have the iacv off check the rubber gasket, looks like an 8 rather than an o. mine was hard and not sealing properly so i threw some sensor safe RTV on it but replacing the gasket would be ideal. fixed all the rough/fluctuating idle issues i was having once the car was warmed up.
and replace all those coolant hoses leading to those idle valves and make sure all the little passages the hoses connect to are clean and not plugged with gunk.
What’s weird is that I dont really have an idle problem…
possibly blown head gasket is my first guess… jus becz its white smoke and smells like coolantt
If it was my head gasket… Wouldn’t it smoke all the time???
Or only at start up, like I’m doing??
depends on how bad the gasket is i’m sure.
as stated in this thread already;
check oil for presence coolant, check coolant for presence of oil/gas.
replace that hose (and others) if they are bad, if it’s not bad clean off where it clamps to the engine.
make sure its on all the way and clamped properly (looks like the clamp is slightly off where it should be).
the water might not even be coming from that hose, could just be dripping on to it from somewhere else.
check IACV for coolant coming through the two holes (doubt it, but worth checking) clean it out & reinstall, if the iacv gasket is hard/brittle replace it because it will probably leak like a mofo and effect the engine idle & etc.
A head gasket can be fully blown or partially…either around the edges of the head or between each cylinder or even between only 2 cylinders giving you intermittent white smoke…it will eventually get fully blown…jus buy a new one like 100$
