I drove by my friend's house earlier and gave him a few tunes from my tailpipes, revving the engine, done it many times before. Get home and temp gauge is up in the 200+ range, shut her off.

Got hose and hose it down, turned her back on and kept hosing it down assuming the fan was turning, look at gauge, 220+. Shut it off as soon as I can. Hose it down and get a floor fan out, cools down smoothly and pretty quickly.

Went out and just now noticed the engine had chucked the belt when i revved it (only 2 houses down from where I parked it) and I guess now I know my culprit, belt was probably too tight or something.

It was only in the 220+ range for a couple of seconds, but it does have SMOG heads (it's and SBC). I put the belt back on and ran her a while, everything seems fine, no signs of coolant on the dipstick *knock on wood* at this point. I am running Mobil 1 10w30 also.

What should I do, run the engine through some heat/cooling cycles to make sure no coolant is leaking and getting into the oil pan? Then change the oil to make usre there's no coolant?

Or?

I wouldn't worry about it. How accurate is the guage? I don't know how accurate mine is either, but I've had my smog head 350 up to 220-230 many times..... no problems.

Unless you notice anything out of the ordinary, I wouldn't worry about it smile.gif

I wouldn't worry about it either. If you watch the gauge after you shut it off, you'll notice it usually climbs at least 10 degrees...

You haven't lived until you have lost a belt like 15 miles from home on the highway AND have to limp home!!

been there, done that with my old, junk 301 several times until I found out I had an alt. bearing going bad...

220 is nothing as long as you're not driving at that temp all the time. Replace the belt and drive it. As was mentioned, on a hot day after shutting it off the engine can jump to that temp easy.

I knocked the petcock off the radiator of my 66 Malibu that I had a few years back,drove it at least 10 minutes to the house,rattling like crazy,would not idle,,got water in the radiator and kept in running til it cooled down and kept it running for a while,never hurt the motor at all. If they're built right,they'll take quite a bit of abuse.

Thanks, car seems to be running fine. Made a 30 mile run to the junkyard and back with no problems, temp at a steady 190 at idle, stopped at read lights, 180ish while driving.

Now, I brought back an electric Ford taurus fan, and I've got the first piece for upgrading my cooling system. Next is a higher output Alternator and the relays/wiring to hook up the fan. At least this way if the belt comes off I'll have a fan cooling the engine til the battery dies.

The only thing I would worry about is that cold hose water on a HOT engine.....CRACK :eek:

I was worried about that too,actually thought I had already hurt the motor and didnt have anything to lose, stuck the hose in the radiator and it cooled down fine, replaced the radiator and it kept on ticking. Even made a pass at the famed Orange County International raceway,and ran a 13.20 with no second gear in the powerglide, swapped in a muncie 4 speed,drove to Missouri from California, sold the car and bought a 68 Camaro.
