Engine heats up quickly

[rare1]

Hey guys. My engine warms up fairly quickly,about 2 minutes till regular engine temperature, at idle. This is my first turbo car and I bought it with no cylinder head so I don't know how it ran before all the work I did. It's got a rebuilt head,180 deg. thermostat,new radiator,new waterpump,timing belt,balance shaft belt, and a new head gasket. Any help would be appreciated.

This is normal. Turbocharged applications produce so much heat, even at idle even with the new parts you have ie. water pump, and thermostat. Might I suggest a bottle or 2 of redline waterwetter put into your cooling system, in a mixture with as much water and as little antifreeze as possible because it is summer and you dont have to worry about it freezing up and cracking your block....but when winter comes flush your system and replace it 50/50.

I thought so but my friends 92 awd doesnt heat up nearly as quickly and he has a bigger turbo{non-watercooled}. Somebody told me that I might have a blown head gasket that lets the turbo pressurize the cooling system and heat it up that way,but I did a compression test and boost leak test, all okay there. Thank You, I was just worried

If you have a headgasket leak and water gets into the combustion chamber it would be characterized by white smoke out of your tail pipe.

As long as you are not losing coolant and the temp stays within a safe range you should be ok.

Good Luck

I know it isn't technically "good" to do, but in the summer I run w/o a thermostat. Around here temps hit 100 degrees + a lot of the time, so I just forgo the t-stat until ~Sept.
Just a thought if it turns into an over heating problem and your strapped for cash.

My car takes about 15-20 minutes to warm up DRIVING it. If I let it idle, it would take a long time to get to temp.

This is normal. Turbocharged applications produce so much heat, even at idle .

When not under load, turbo motors don't run any hotter than NA engines. In fact, due to their lower compression ratio, they probably run cooler.

So long as you're not overheating, don't be concerned with a rapid warmup.

Never run a modern car without a thermostat. You're begging for scorched and scored exhaust valve guides.

Your thermostat is leaking. Replace.

I agree, its never a good idea to run w/o a thermostat. Most thermostats have a variable spring that controls the flow rate of coolant. Running with out one is causing your coolant to be passed through the cooling system and cooling off the coolant all the time. Hence your engine runs colder than normal operating temperature and will give you a rich air/fuel mixture condition. Not only does it cause you to run rich, but your bearings will rapidly wear due to oil sludging from being too cold. Running your fans all the time isn't good either because you can bring the operating temperature down and cause it to run rich. Only time its necessary to run your fans via a switch is at idle.
