So here is the situation, about a week or so ago I hit vtec and all that jazz, come home and find that coolant sprayed all over my engine compartment from the overflow bottle of all places. So I clean it up and check the coolant level and it's low. So i add more coolant to the radiator to top it off. 2 nights ago I checked my overflow bottle and it was at the max line even after it cooled down for about 4-5 hours. So I drain the overflow bottle to get to the min line and check coolant in radiator and it's where it needs to be (did this before and after I drained)

I decided to give the car another run today and all seemed well (2nd gear pull only). I check my engine bay and there is no coolant spray that I saw. I have since let the car cool down about 4 hours now since 5pm and I went to check the coolant. I see that after 4 hours the coolant is still at the max line with coolant missing in the radiator (presumably drained into the overflow)

This thing happens only when I hit my vtec, normal driving is perfectly fine. I dont think there is an air pocket in the coolant system but I have been wrong in the past. I dont want to vtec again for fear of spraying coolant everywhere again.

Thoughts? comments? advice?:dontknow:

PS - It's not overheating because of the fact that my temp level stays put even after this vtec/coolant/crap.

Check your oil for coolant. Milky... yucky looking stuff. lol

If there are signs... DON'T DRIVE IT! You can change the oil but I still wouldn't drive it if you saw signs of coolant in the oil. It could mean a blown head gasket.

If that's not it... well someone else may have a guess.

I tried that too, checked the oil from the dipstick and even the oil cap, no milky stuff in either area.

Hey have you tried blasting the heat to see if you get any? Wrong time of year I know.. lol See if your radiator cap works good too and doesn't look worn out. If it won't hold pressure to the system then the boiling point is reduced significantly.

rad cap. extra internal pressure from the water pump spinning at high revs is a bit too high for the cap to handle. it could be weak from age or you just need one with a bit higher pressure rating
