such thing.. Too much coolant?..

[SLOsClipse]

So if you put too much coolant and not enough water in your mix for radiator, will it cause' your engine temps to spike drastically?... or mixing coolants?

Not drasitically, but it will rise a little bit because water cools better then coolant. I run 70% water, 30% coolant.

i just replaced my radiator... now I went driving and it spiked fast and hard!! babied home... now whatg?? UGH!

flush and get new coolant and mix 50/50

pray its not your water pump

Head gasket. Run a compression test. If that checks out good then do a cylinder leak down test. If that checks out good change the thermostat it might be stuck closed.

If you didn't burp the system while filling it then you'll need to refill. What I usually do is fill it, let it run and fill during the run. Then put the cap on, let it get hot, then let it cool down and refill then I KNOW my system is full.
Edit: the reason I do this is because if you just fill it to the top before starting the car, or even when you dont let it run long enough, there is still air in the system and it WILL overheat, no matter what you think. There will not be enough fluid and it'll toast.

^ I do the same with mine, its the best method for sure.

I like to squeeze the lower radiator hose while burping the system.

Check for air pockets like the 2 above mentioned. All coolant does is raise the boiling point of water, lubricate the water pump, and lower the temperature for the water to freeze.
Water is what cools the motor, not the antifreeze. So basically, more water the better. I wouldn't suggest a straight 100% water but if you do, mix in some antifreeze and water wetter into the mix.

+10 on the water wetter. Me and my dad used to run that in the race car we worked on out here at the local dirt track. In the late model class(their motors have more horse that NASCAR motors). +10 on burping the system. There is a pretty nifty tool that you put where the radiator cap goes then hook it up to a air compressor and the way it works it sucks the air completely out of the system and puts it into a vacuum and then you take the air hose off and then put the hose connector on it and put it in your bucket of water/antifreeze and open the little valve and then the vacuum in the system actually pulls the mix in and leaves no air pockets its called an Airlift is the brand and its called a airlift though.

I would look into a new thermostat like mentioned b/c i had a faulty one that wouldn't open all the way and the second I would take of my temp would shoot up quick.

if you have not did a whole system flush on your coolant. do it now. I found a small silicon piece that was blocking the water passage in the thermostate housing. do a new system flush and replace the water pump( if you have not did so) than it will be fine.
