For some reason my water pump belt snaped while test driving and my gauge got to about 85% before shutting down. How fucked am I ???

 

ok does anyone see my posts or am I in like invisible mode?????

 

it seriously shouldnt do anything bad just make shure to keep an eye on it next time

your engine should be ok.

 

Now is when you realize the wisdom of dual water pump belts. If your air pump is removed, get a dual pulley for your alternator.

Only you can answer your question. Run it again (once you fix the belt). If it overheats badly, smokes white sweet smoke, or burps coolant out with exhaust-smelling bubbles, you're due for a rebuild. Otherwise it's probably OK.

as long as you didn't put it up in the red it should be okay. If it hit the red at all then you're coolant seals are probably shot.

 

Thanks for the responces everyone I was beginning to think no one liked me Anyways I didn't let it get into the red but 15% more and it would have. I was just driving around the block when I heard a loud Pack! and then blue smoke and then rubber smell. Anyways I was about half way around the block when I noticed it get to above half and then I was home and shut down by 85%.

 

It only takes one time for the seals to go bye bye.

It may drive for that remaining day or month but they will go.

I over heated twice in my GTU and then 2 months later it left me on the side of a road for 3 hours.

 

I was sitting at a stop light and looked down to see my temp gauge rising like that. It also got to 85% or so, I pulled over and shut it down; put a new belt on (from the trunk); and drove back home (600 miles).

That was in my 88C 6 years ago. Engine still running strong.

 

I love your avatar.

I drove my 10AE about 30KM with it at 3/4 and about 5 KM with it past the H.

no damage.

 

Mine? If so that is a first Anyways thanks everyone but digi7ech for giving me some hope, lol, jk digi! Anyways I'm going to pull the fan and everything back off tomorrow to change the damn belt but if thats the only thing I have to change I won't complain. Thanks again.

 

That's what you think.

Like I said. It may not havw crapped out that second.

It's probably reduced the life span of the engine by a few years at the minimum.

 

damn digi you ARE the voice of dispare, I think I will just ignore you lol. Anyways do you think its that bad for it to reach 85 percent? it didn't over heat just got real hot.

 

Well.

If your really lucky the seals weathered it well and they will last you a while.

I say this stuff out of experience.
Over heated my 88 SE once or twice.
Then months later it started puffing some white smoke(coolant seal)

Then 88 GTU like said above went out a few months later after overheating time.
I hadn't gone rev happy or anything the day it went out either.

 

Though it is true. Litteraly took years off it's like. I always heard with the shitty stock gauges anything over 50% on the gauge is overheating...

 

Digi, nice ride man! Love those GTU models.

 

halfway up the guage is nearly operating temperature on the S5's. Half on the guage should be okay for an S4 but obviously your cooling system needs inspection.

 

S4 guages are good for actual readings.
S5's have been said to have 3 settings. Cold,Running,Dead engine......

At about 1/4 up a S4 guage your at 180Degrees.

1/2 -3/4 your close to 220-250

I know because I had a Autometer temp unit in my 88 SE.

 

all new cooling system including koyo radiator just my water pump belt broke and yes its an s4

 

I wouldn't worry about it. Just because the engine got hot, doesn't mean it's instantly dead (even though I make a point to say that on my website...it's for scaring newbies to fix their cooling systems). As long as the engine wasn't under load, and you noticed immediately, you'll be fine. It's really the excessive overheating under load that kills things. Or having marginal o-rings to begin with.

 

My 87 kept trying to overheat until I noticed the fan clutch was worn out.
Six months later the oil rings started to go but the O-rings had no problems.
It just smoked (blue) more than normal when you held a fast idle for a while.

 

Well, while we're here, what would "hot" on a 88 SE be considered? During light highway running, my gauge runs about 1/4, and with the AC on or during hard driving, it gets up halfway or about a needle's width over halfway. Is this anything to worry about? I've heard that the gauge calibration changed on the 88s so halfway was normal, but other places say halfway is getting towards the hot side of things.

halfway is starting to get on the hot side of things for an 88. Normally I'm at 1/3 if I'm driving hard (TII). 1/4 is about normal operating temperature. 1/2 probably won't hurt your car, but it is getting to the point when I'd start worrying about things like turning the heat on full blast and maybe a bottle of water wetter. if it only gets up to 1/2 when you're driving hard then i would suggest rolling your windows down and turning the heat on full blast. That's good for a few degrees right there. Watter wetter is also good for a few degrees.

 

How much does ambient temps affect the guage reading on the S4's?

I have an '88 TII. I have removed the air pump, running a duel pulley setup with a FD alternator, but the belts are not exactly the same size, so one belt is noticbly looser than the other one, but I haven't seen any slippage from it. I am still running my clutch fan.

On hot days my running temps seem to be running slightly below half way (like a hair or so) On cooler days it seems to be more like 1/3. Hard driving brings up the temps a little, but I haven't seen anything go above half way...

I live in South Carolina on the coast, so I'm at sea level and see average ambient temps of ~100 degrees F (with heat index correction) during this time of year.

Should I be worried?
