Honestly just change your coolant mix to be more water based, coolant had a low freezing temp and a high boiling temp. For a daily driver you guys started off wrong. put actual coolant mix in it and let us know whats up.

Well it turned out to be a bad HG. thank u for the help everyone

Triperformance · 06-13-2010, 06:29 PM

You see that nasty water pump a few posts up missing it's fins, it could eventually cause it to seize and then the pump goes boom. I just recently fixed something like that one a toyota t100, it was so awesome. I really never thought something like that could happen in the cooling system. I guess it has to do with what anti freeze's purpose is..

I'm not a genius so scientifically I dunno what the fuck happened. All I know is I saw some shit explode and it was epic and there wasn't a piston or rod behind the part that blew up.

lol, T100 is pretty old dude. Toyota and water pumps is nothing new, consider every 60k miles to change one, which is why most people replace them during the swap cause the jdm engines can have up to that mileage.

Corrosion and water pumps don't mix.

Use inhibitor/antifreeze

Sounds fun lol. I guess antifreeze is a good thing. Lesson learned today....USE antifreeze.

Im not to worryed about the HG its not my car (cant see it from my house) lol. But on a real note. I have a extra HG sitting at my house im giving him and he's picking up some arp's also. It just sucks cause the guy that he bought the engine from said it has new rings and bearings. So that prob a lie. Atleast we found the prob.

Om1kron · 06-14-2010, 12:02 AM

Sounds like your typical rebuild (lets rebuilt the bottom end, not deck the head) and slap it together with a head gasket.

s14kdizz · 06-14-2010, 06:28 PM

the problem with it over flowing in the res would be air in the system but i found out by letting the car run longer that there was a little more then just air in the system

BLKTOPSR20DET · 06-23-2010, 11:43 AM

the coolant lubes the seals and shit like that in the cooling system and it boils up at higher temps but its always better to mix coolant with water 50/50 mix and if you have a blown HG sometimes the motor oil doesn't get milky and sometimes when you do a compression test it dont show low compression it might just be a small hairline crack in your HG a friend of mine had the same problem or you just might still have air in your cooling system
