Running No Thermostat

[Guest trikdoutvl]

Simple question, will running no thermostat make my rb20 run hotter? I had my car overheat on me and the cultpret was a bung thermostat.. So I pulled it out and now the car runs at around 190-200f. It tends to creep up when I am idelling at the lights. Just wondering if removing the thermostat would have caused that or should I put a new 1 in??

I would have thought no thermostat would just mean it takes a lot longer to warm up which isn't a good think, If its a daily I would deffinately put one in..

Buy a thermostat, you probably have a circulation problem now . The thermostat blocks the bypass when it opens up and allows water to flow through the radiator, so hot water is probably recirculating around your block.

Pulling thermostats out only works on old cars.

pulling out a thermostat will cause ur engine to reach full operating temp a lot later meaning more wear and tear. it will not cause it to over heat

put a thermostat back in, if its overheating with a new thermostat in there you have a problem

-new thermostate

-radiator service

should be sweet after that as it covers all bases, if problems persists consult your local GP

I should of added I had the radiator flushed the same time I took the thermostat out..... My temp gauge is aftermaket and in farenheight.. Is 190-205 normal temp for a 20? It goes up down between idalling and driving. I was thinking of installing thermo fans next.

$16 new thermostat, full coolant flush, new oil, check for cracked head gasket.

i noticed in my car it ran much cooler but it can screw with electrics with your EFI, when your ecu depends on water temperature to decide how much fuel it needs to put in when u start car and so it knows when car is warm to convert back to normal map.

thermo's block flow to the radiator until the car warms up, then open to allow it to stay at that temp via radiator cooling. your car overheated cos the thermo was stuck closed causing it to be in the "warm up" stage until cooked.
