Ah, was completely ignoring the fact that occasionally engine temps can go well over the desired operating temp. So basically you only would want to increase the pressure if for some reason you wanted to run your engine hotter(and it was designed for it) and your radiator and thermostat were adjusted as well or if for some reason you had to run a lower coolant to water ratio and the system can deal with the pressure?

Hubs are fairly easy to replace, ~$75 on Amazon for a Timken last I checked. Could be brake related as well. The dust shield could be rubbing or the pads are shot and/or a combination of a seized caliper.

 

The system is designed for a 50/50 mix of coolant and distilled water, and a 13-16lb radiator cap. When the fluid heats up, it expands and builds pressure. If it gets too hot, the pressure would build indefinitely and you would find the weakest link in your cooling system. The OEM radiator cap is rated to give the widest range of operating temps possible, before releasing to "blow off" pressure, so your radiator tank/cooling hoses don't burst from excessive pressure. It functions similarly to a turbo wastegate in that regard.

 

Additionally, letting off pressure is part of normal operation. Reservoir level fluctuates constantly.

 

Just out of curiosity whats the formula for that? also what about a 70/30 mix? or a 60/40?

 

too much coolant can eat up the insides and not enough coolant can cause inside to rust out

 

Also, too much coolant (really, not enough water) doesn't transfer heat very efficiently. Too little allows corrosion to occur, as you mentioned.

 

I'm not sure. I looked up the numbers to make an accurate post.

 

lol... glad SOMEONE ELSE finally got the picture here.

Let's not forget the obvious... too much water to coolant ratio will allow the water to freeze during the sub-freezing months

 

Anyone know of a flasher relay that will work with LEDs without resistors?

 

I thought you just got one?!?!

 

didn't work, tried it and it did the exact same thing as the rest. Went to the auto parts store and got one that actually works just now, but here's a new problem. When I turn the lights on, both of the turn signal arrows dimly light up, and this causes the front side markers to be dimly lit.



Also, when I hit the brakes the turn signals, and interior dash/gauge lights light up.

 

What is this harness for?






One wire is red (pink?) and the other is black. Looks like a sensor but I couldnt find anywhere to plug it in.

coming off a 98, 2.5l.

 

Under hood light?

 

I think you're right.

 

Add a power resistor in parallel to match the resistance of the original bulbs. 1/((1/R1)+(1/R2)+...)
