Angry Overheating

Talked to Everett and I know what Im going to do but figured Id put it out here

SO Last summer my car started to heat up really quick sometimes overheating and blowing out coolant when it was not moving. I deployed in June so I didnt really mess with it and In November when I came back I took the whole front suspension apart. Well 2 months later and alot of patience I got her all back together and wanted to go for a spin. Well while driving it was fine and really only 50 degrees here in Virginia Beach. So during the drive it didnt heat up. I get back home and park in the drive way leaving it running so I could talk to the neighbor about my car and have a cool guy feeling because it sounded so nice. Well out of nowhere it starts smoking because its spewing out coolant out of the radiator overflow tube thing. I shut it off and saw that the temp gauge was maxed at 300. After talking to everett Im going to start by changing the thermostat.

I didnt see any belts slipping but another option is the water pump. So what do you all think? Sorry if my terminology is off. This has been my first really car that I have ever done anything to so Im learning....slowly! oh and when this all happened I looked like a little kid falling on the ground kicking and screaming

Re: Overheating

If you have a clutch fan it may need to be replaced.

Re: Overheating

Times 2 on the fan !! If it stays cool when you drive it,but heats up when you stop and let it sit there running, must be the fan!!!

Re: Overheating

when the car is moving there is lots of air going through the core, the min you stop the fan needs to do the same, if you don't have a shroud the fan picks up the hot air from all around the engine and not through the core to cool the rad off if you do have a shroud maybe a plugged rad or even a wrong water pump the one with the opposite rotation. timing is another thing you need to make sure is ok.

Re: Overheating

You need to put a shroud on it first, that may well fix your overheating. Drive it, you will know if you warped a head quickly, it will start blowing steam out the tail pipe all the time, probably lots of it.

Re: Overheating

One of the things I always liked about fan shrouds is if a blade comes off the fan the shroud will probably contain it so it doesn't smack up the hood or even cut hoses and lines. Or stick in someone's head if the hood is open.

over heating does cause detonation, but to be safe check your timing.

Re: Overheating

Shrouds are necessary evil just use cleaner and polish. Plus it's a good place to put stuff when you are working under the hood and stops wrenches from falling an hitting the radiator and making holes.lol PS glad you did not hurt anything

Re: Overheating

well Im going to go ahead and get a shroud and replace the thermostat. Its cheap anyway and rather easy from what Ive heard. At least this way I have taken two factors that could be contributing to the issue. Does anyone know if I would need a 180 or ? Thermostat. Its a 350 so not sure what the difference would be...

Re: Overheating

Benito - Full system check list:
Test existing thermostat before replacing it on your stove with a candy thermometer - should open fully at 180 degrees. If not replace with new 180.

If your fan clutch is in working condition once you put the shroud around it should pull enough cool air while parked. When at temp does it look like it is spinning normal speed?

Also check your water pump to see that it is belted without slipping and the impeller is not all chewed up so it is pushing the right amount of fluid.

Open the radiator cap and start her up, watch as she comes to temp for good full flow in to the tank if you got weak flow recore the radiator.

Other possible cause are timing issue and a stuck passenger exhaust "heat riser" sending exhaust back through intake passage if so equipped.
