thermostat question

[gumtree]

if u take out a thermostat, will it effect anything in a bad way. the point of doing it to get full coolant flow and better cooling. if i take it out i know it will take longer for the engine to warm but will it hurt the car taking longer to warm?

You'll get crap fuel economy as the choke won't come off and the engine won't get to optimum running temp hurting performance (running rich all the time will strip the oil of the bores leading to faster wear too). The thermostat was put in there for a reason. IF you are getting hot running temps you should fix the problems instead of bandaiding it.

Hey man, my mate had over heating problems in his hilux, and first thing he done was checked the thermostat, and it didnt have one in it, he hadnt noticed anything going wrong with his engine, over heating problem was from his radiator.

yeah give the radiator a good flush or 2 and check the thermo is working.

took the vitara to the radiator place a couple months ago for a full radiator flush and engine flush. added new quality coolant and a new thermostat.

the car runs fine all day long even with air con on but as it goes up steep hill like over a range or a few minutes of constant climbing it creeps up to 3/4 (normal is 1/3 way up). that is why i took it in and its still the same as before pretty much.

i thought coz its an auto and has that big auto gearbox radiator behind the normal radiator the air flow wont be as efficient as a manual? Joe blow said maybe they need to take the radiator and actually shove rods down it to clean it properly rather than just flush it with pressure.

any other experience if this is normal for an auto?

If the coolant flows through the block too fast it does less to cool than coolant flowing at a slower rate. Also, the longer it stays in the radiator the cooler it gets.

Put in a thermostat, but drill a small hole in it, about 3-5mm.

These are recommendations by a mate's dad, a NATRAD owner...

Keep it factory. components in the cooling system are there for a reason. chuck the thermostat in a pot of water and heat it up to see if its actually operating properly.

In saying this my cooling system that i'm building at the moment will run a restrictor disk instead of a thermostat. but coolant temps will be monitored electronically and will run pumps and thermos to maintain correct operating temps dependant on what the coolant temp is doing.
