I start my engine from bone cold and in 1 or 2 min it reaches 220*!!! And it dont have the stat on. I beleive is the sensor or the gauge.

What sensor did you used?


Thanx

Also I noticed that whe I start the engine a whine sound comes from the engine. Its like supercharger sound but not loud. Another thing is that I can hear the valves thiking all the time, is this normal?

Are you sure the noise isn't the injectors clicking (normal)?

The temps sound like you have air in the system assuming the gauge is working right. We used the stock gauge sender (green wire, not brown/yellow. That's for the ECM).

The whine is likely the timing belt. Normal on the one's I've been around, but it wasn't real loud. Could be the alternator too. Remove the accessory belt for a second and see if the noise goes away.

We flushed the cooling system system and the problem persist. A un usual behavior was that some times the gauge was 2 lines above 100* and then start to climb to 200* then go back to the previous position. This was with the the engine in idle and direct radiator fan.

Other one is the engine in idle at 200*, turn off the engine and put the switch back on and the gauge start to lowering the temp pretty fast to -160 and we fire up the engine and then it goes to +200* in fast.


About the injectors clicking I will have to verify. It sound like lifters but im using 5w30 to make the oil get all over faster. Is there any way to know if are the injectors??


The whine sound is like u describe. Sure is belt. Makes sense. I adjust it very tight.

Thanx

My water pump made a "super charger" like sound just before it died... Im pretty sure I over tensioned the belt, which caused pre-mature bearing failure..

It'd still push some water around, but not very much..

How long does it take to swing up and down? In seconds, it's air (usually), in a minute, it might be normal since it takes time for the coolant in the front to flow to back and close the stat back off. Getting all of the air out takes a couple of burps.

Getting to the injectors is a bit tough but you might be able to get to an end injector and put a long screwdriver to the body of one with the handle to your ear and use it like a stethoscope. Injectors sound more like clicking vs the rattling of low oil pressure in lifters. Both will follow the RPM in rate so that doesn't help much. You can try turning the TPS while the throttle is closed. It will put it in power enrichment and the injectors will change sound. If it's lifters, it won't. Doing that will make the engine run rough for second.

My engine dont have the stat. Since day 1 I had overheat problems. The first time with the stat on while we where fixing a few stuff a heater hose blew off. Since then I running w/o stat.

Its possible that hooking the exahust(cat and muffler) did this effect????

normally you would want to run with a thermostat, it is there to restrict the flow down to a usable level. the antifreeze flows through the radiator too fast for the radiator to cool it down. but this is only noticable on warm days and the temp would not rise as fast as you say.
first thing i would check is to feel the radiator hose at the front of the car when the gauge says it is getting hot. check to see if it is warm to see if the water is flowing through.
on my swap i modified the 2.8 housing and put it on the 3.4 and i can take the cap off and put my finger in the water to see if the water is warm ,which means the water is flowing
