My car is acting really funny. I turned it off the other day and heard something shooting out like an air leak or something so i popped my hood. I opened it to find that my coolant was shooting out a bunch of air and some coolant into my resevoir. My coolant is a little dirty if that helps. What exactly does this mean? Car still runs fine and all... ??

 

sounds like either a bad rad cap or you overheated the **** out of your motor. if you did the latter, im sure you'd have mentioned it.

 

thermostat stay closed maybe?did it overheat?

 

Was the vehicle overheating when the coolant was shooting out of the reservoir? The easiest test would be for combustion gases in your coolant which would indicate a blown HG. The radiator cap opens to allow the pressurized coolant into the overflow. It also opens to allow that same fluid back into the radiator once the vehicle has cooled. The cap was venting the hot coolant into the overflow but it was pressurized even after exiting the radiator. This points to a HG issue unfortunately. hth

 

well i'm doing a head swap soon... so part of me hopes its just the HG. It didn't overheat.

 

hey so im new here and im sure this has been asked but here goes have a d16y8 in my 98 lx car runs amazing lots of power no smoke no smells no leaks but my coolant back pressures upper read hose to the point ive blown one ive changed water pump tstat twice rad cap twice and just did the rad from what im getting from reading its starting to sound like a head gasket but i dont get it cause it runs mint lots of power no white smoke etc it has cold air intake throttle plate header 3inch exhaust and has a g-force chip

 

Take the radiator cap off.
Start the car with the hood open.
Rev the engine a little.
If water shoot out the radiator, you need a new hg.

 

just started car took rad cap off and reved up engine it shot straight up so it looks like im doing the head gasket i already anticipated it was this so i picked up another d16y8 head im thinking about getting it milled 3thou and a 3degree grind any other suggestions while its off of the car on a budget but can do some mods..thanxs in advance

 

Could be a ton of air in the coolant system.

 

2008.
Would be funny if he's still got the issue!

 

NO! Fooled by a new user bumping a 5 year old thread AGAIN!

 

got my head back from shop he milled 6thous. off of it didnt bother with the valves or anything i picked up another d16y8.. going to do a rebuild over time on it but for now i will just do head gasket on this one... gottta love pick and pull got motor(block) and head for under 200 bucks... and wont be funny if i still have same issues pretty much cant be anything else did water pump timing belt tstat twice rad cap twice and rad too....fingers crossed

 

What? This isn't your thread and you're bumping it with something completely off topic.

 

Pulled into my garage yesterday, heard something like water bleeding out of something. Opened the hood, saw coolant under the hood, coming out of top of the overflow bottle. Car did not overheat and it was about 96 degrees yesterday, drove it 28 miles from work. This morning, the coolant level in the overflow bottle was down between max and min lines. Anyway, tried the method below. When I took of the radiator cap, coolant spilled a little as it was full. Reved the engine, saw some coolant flowed out over the rim of the radiator but nothing shooting out or up. After the first rev, I really had to rev the engine up to see a little coolant flowed out of the radiator rim. Checked the oil and it's good. Could it be HG or something else? Thanks
