My car has recently started to run like crap. Like it did when I had a blown motor. The motor seems like it is very hot. after shut down I check the underhood area and everything feels hot (more that normal) No cats on the car so it's not a cloged cat. M2 intercooler and cold air intake so it's not that. Turbos seem to be boosting as normal. I only run 12 lbs. I'm not using coolant as far as I can see.
Only thing I can think is it may be a stuck thermostat. Has anybody removed it from the car and run without it? Is it possible?
I can't remember if the car seemed hot when I blew the motor the first time but does it run hot if blown?
Thanks guys.

 

You might think about cutting the "guts" of the thermostat out and leaving the outter metal ring in the filler neck. The ring will act as a reducer so the coolant will not circulate so fast.

 

I put two 1/8" holes in the thermostat body flange and this seemed to drop the high speed temperatures a little. Perhaps I need to increase the flow rate more.

 

what water temps are you running? also, are your fans working?

 

Don't remove the t-stat, the coolant will flow too fast. Perforating the diaphragm/gutting will work better. As the others said, make sure that your fans are working on all three speeds. I had a t-stat go bad myself earlier this summer....

 

Fans are working fine and the heater works so I don't know about the tstat? I don't know what exact temps I am running but the car feels a lot hotter after I shut it off. and there is the lack of vac it was at about 18-19 lbs of vac now it is going to about 10-11 lbs?

 

DANGER DANGER

DO NOT REMOVE THE THERMOSTAT AND DO NOT GUT IT. Why?

Look at it. There's a flat disk end that is spaced from a bypass port in the thermostat housing when the engine is cold so that some of the coolant bypasses the radiator straight back into the block.

When the engine is hot, the flat disk end abuts against this bypass port to prevent coolant from bypassing the radiator and therefore coolant must flow through the radiator.

Remove the thermostat and a major portion of the coolant will not flow to the radiator as this portion will bypass through the port. Don't ask me how I know.

 

Remove your thermostat and test it or replace it. Simple as that. In the grand scheme of things it doesn't cost that much and the removal/install should be less than an hour.

Cheaper than getting a new motor. DO NOT REMOVE IT. As for gutting it...never tried that.

 

I'm going to try the tstat to see if it's good, but as the heater works VERY well It may just be a blown motor.
I got a check engine light last night too so that's not good at all.

 

ill be right over. never leave a boy hanging.
