yet another thread about the crankshaft pulley...

[mssteed]

When driving along about 2 months ago, my crankshaft pulley bolt decided to snap right off and long story short, we replaced the bolt and torqued it on at 160 lbs. It is wobbling though, is this because it is supposed to be at 180 lbs? Also, the car started overheating a bit and the battery is running low on volts. Usually runs around 14 but it's been on 12 and almost dies when I am still and I turn the wheel. This only happens sometimes and started about a week ago. The crankshaft pulley has been fixed for at least a month. Are these two related in any way, or do I just need to get a new thermostat and battery and tighten the crankshaft pulley?
I have a 1992 lude with F22b JDM original motor if that helps at all (please don't say that doesn't exist)
BTW, does anyone know where to get any kind of repair like manual for that motor? I can't find it listed in any parts stores so far (i.e. auto zone, advance, napa,etc.) And it would be nice to not have to research what parts I need for hours.

Since the JDM F22b is VERY similar to the USDM H23a1, I would download the helms manual in the FAQ section and use that. The main differences are the internals; bore, stroke, crank, etc...
But all the external/accessories are ALMOST all interchangeable.

When you simply slide the crank pulley onto the crank (before bolting it down), can you wobble it by hand? Cuz you shouldn't be able to.

The alternator belt could be slipping due to the wobbling, which wouldn't charge your battery correctly.

And when does it overheat? At idle, on the highway? All the time...

Thanks for the info. It is overheating mostly at idle. But sometimes on highway, usually on the highway if it does start to get hot I just flip on the heat and it goes back down in minutes, but during idle it is worse and the heat doesn't really help it much.also when idling the rpms go up and down for around 15 to 20 minutes which I have been told is the tps (throttle position sensor) could that effect anything. Of seems also that the battery is losing voltage as I drive along, it will start at 14 then slowly go down to 12. The exhaust being very loud, also sounds much deeper than normal.
My Bf says that he remembers that he could not wobble the pulley before putting it on, but he could be mistaken. Thanks so much for your help.

Hahaha sounds like you got alotta problems goin on.

Overheating and a bouncing idle are both symptoms of low coolant, or an air bubble in the cooling system. Check your coolant level, and if its good, continue with this thread;
the FINAL idle problem thread!!!!!
^^ That's only related to bouncing idle, and if its still overheating after you check all those, then its a bigger problem.

Exhaust leak is negligible, wouldn't really affect anything.

Hows your AC system work? Does it overheat when you turn it on? Does it blow cold?

do our cars have coolant temp sensors ?

Yeah it has it's fair share of issues. When u don't have much money to maintain it, problems seem to stack up. But we figured out the problem. The battery is bad, which I thought it was, and we figured out we put too much seafoam in it, yeah were idiots, so the oil is too thin. So, we are going to change the oil and get a new battery. Also found that the idle issue is the map sensor I think it is called? Something like that, either that or we need to clean out the throttle body, which we are going to do. As far as the crank pulley, we looked at it tonight and it wasn't wobbling at all... Not sure if it fixed itself or what. So all and all not too bad of news.
