240degs?? did she over heat

bianchi1 · #1 (**permalink**) 10-12-2007, 03:52 PM

just wondering.. just fixed my car.. ran it for a while.. saw that the temp was 240*

only for a short time( was warming up the car)fan did not turn on. the temp was only there for 2-3 mins at the most..shut the car down lots of gurlging sounds

, re conected the fan.. works ok..started it back up. reved it no steam at all. cool rainy day here in sunny n.cal.

( yet????)should i be woried.

. new head gasket , only 2-2.4 thous.on it... thanks

Don't worry about it.

You are probably ok, but if you really want to know, then top off the oil, and check if there is any additional consumption over the next few weeks... Engines that have higher comp pistons, ported heads, and high lift cams do warm up a lot quicker than stock engines, because they generate more heat. You have to be careful about overheating a "performance" engine, as a head gasket does not have to blow for there to be an undesirable consequence...

Best regards,

I don't suppose there's the vague possibility that the gauge sender wire earthed and made the gauge run up like that is there?

I can't imagine how a cold engine that was being idled to warm it up could go that high in a short time. (presuming your warmup was less than say, 15 minutes)

Well, I could imagine a few causes actually:

Belt slippage
T-stat totally blocked and unopenable
Seperated vane plate inside the waterpump
Really whacked ignition setup
Massive false air leak between the head side of the throttle body
And mabe a few other things.

Yes, higher performance intended parts can make for quicker warmup, but IIRC, bianchi1 isn't set up too much beyond stock, so one would imagine that to get super hot in a short amount of time isn't really 'normal'.

I guess it would help to know what he's got going on in the engine and how long the 'ran for a while' timeframe actually was.

.. can't sleep.. head is not milled, just a really good port job right now.. the elec. fan was disconected.. as for time...no more than 3- 5 mins of running time. including a short drive around the parking lot..only sitting running the motor ofr a min or so after that.

That high in 3-5 minutes doesn't seem like it's even possible, at least in the sense of a normal warmup cycle.

I'm falling back to the sending wire is/got shorted and spiked the gauge.

the elec. fan was disconected, i guess while i was doing some bodywork, i must have dislodged the connector

.. so far it's ok..on the crankcase hose to the oil seperator, i have a clear hose, so much yet...run's fine.

I gotta learn to focus more I guess or drink less

I overheated my old spider, blew a heater hose, noticed it right away and shut down, still cooked the valve guide seals.

Water under pressure won't boil until well over 250 degrees F.

Taking into account inaccuracy of the temp gauge, system at about 15 psi, steam chart says water boils near 260 degrees F. That's not taking into account coolant mixture and altitude.

I agree with Papajam, you need air circulating through fins of radiator to effectively cool. Drink less, stay cool. I have same problem
