So I bought this car recently..... Replaced the radiator.... Yet it still pukes up coolant every time I shut the car off and have to refill before I go anywhere....

Now tonight I have been fighting an issue where the car hesitates and bucks under partial/cruising throttle... doesn't matter the speed, happens under like 3k rpm. After driving for about 10-15 mins it drives normal again.

Whats up with these issues?

It pukes coolant? Where, does it burn it as in smoke cloud or leak? Is it over heating?

NavyFD3S

will puke from the overflow tank..... It will only overheat if I don't get it filled all the way and there is air left in the system.

I would do a presssure test of the coolant system

Yea pressure test... Although if youve overheated it a few times it may be the least of your worries.........

Thats what I am worried about. Contacted a builder in my area to see about a rebuild. Going to be doing pressure test tomorrow and see what I find....

NavyFD3S

Did a pressure test... no leaks found... System held pressure.....

Removing the overflow tank from the system all together and blocking the nipple on the t-stat housing?
I do have a Megan Racing Radiator installed

Did you test the cap?

NavyFD3S

replaced the cap

do you see bubble in the coolant with the engine running and the cap off?
