so i went offroading for the first timeat tahuya in my new truck its a 90 with a 22re and i went through some miniature "lakes" and in the middle of one my truck died and flooded it. ever since then my truck has been acting weird i dont know how to explain it it just hasnt ran right.
any input would help me find/fix the problem thanks.

also beside that when i got the truck my motor didnt read on my temp gague so i swapped the thermostat and it fixed that problem but when my truck is warming up it goes to the red then cools down. what could be causing this

thanks

 

This tends to be fairly normal..
My 92 22re did this same thing and I never worried because it always ran fine and never got hot.
I attribute this to the location of the temp sender for the gauge versus the location of the thermostat. The thermostat opens and it still take a few minutes for the water to get to the sender. So this shows a high temp for a few moments until the cooler water gets to the temp gauge sender.
I would not worry about it at all.

 

1. check you spark plugs cap and rotor might of got some water in there some how. Also on the temp might have some air bubbles in the cooling system did you flush the system when you replaced the T- Stat

 

thanks ill check that
and no i did not flush it should i have?

 

I'll second the air trapped in the cooling system. The quick overheat and then cool off is symptomatic of a temporary hydrolock that pushes through on its own under pressure.

 

Hydrolock, aka "hydraulic lock" is caused by the displacement of compressible material, a.k.a. the air/fuel mixture, by non-compressible fluid, most likely water, which prevents the movement of the piston through its stroke because fluids like water cannot be compressed to any appreciable density.
"Temporary" hydrolock results from sufficient fluid being ingested into the cylinder to cause a misfire in the cylinder yet yields enough compressible volume to allow the piston to travel through top-dead-cylinder without stressing the reciprocating assembly enough to cause deformation of the connecting rod(s) of the affected cylinder(s).

Hydrolock, hydraulic lock, is neither symptomatic nor resultant of overheating.

Can we get some facts here?

Besides that, regardless, how can it push through on its own, and under pressure at the same time? It either would push through on its own, without help, or push through due to pressure, which means the pressure helped it push through, no?

 

have u checked your air filter water could have rotted that..
how deep in did you go? if it went above the hood try unpluging all the electricals on the left side and letting them dry

 

Good point, and thanks for being so polite about it...

Airlocked is what I meant... Again, typical in 3.0s, not familiar with 22re so???

 

yeah dude , remove your spark plugs , and then turn the motor with the key , gently , this will blow out any excess water from inside the cylinders, then replace your cap and rotor , and you might wanna change the oil , your oil may have got contaminated with water.......

 

for future reference, your bland generic title will get your thread deleted by mods, you need to add some detail to it. Define "runs wierd" does it run rough? is the idle too high? some details would be nice. So you flooded the motor and stalled it in water? did the water get to your seats? if so.. your ecu is by the passenger side kick panel and could have been submerged. If theres moisture in the tps its gonna run bad. Hell if theres moisture in anything computer controlled its gonna run like crap.
