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?

 

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....

 

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?

 

replaced the cap

 

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