Facing front of car is bottom right at rear of rad.

Funky, drains slow.

If you pull out very far after clearing threads it doesn't seem to want to go back in far enough to catch a thread. But, it will, just push in harder.

got the coolant changed, i decided to drain it from the drain plug, took 1 and a half hours frown.gif Also changed the oil, made the mistake of putting 10w40 in instead of 5w30 and now my oil pressure gauge says i am running 255lbs of pressure. I guess its just not used to 10w40. Theres nothign wrong with the oil levels. I think i will keep it in there till my next oil change and then put 5w40 in, wont hurt it any i guess. Still trying to find me a reconditioned brake accumulator tho, cant really afford a new one right now. (hint hint readers)

Are a lot of postings and even a factory TSB about erratic reading oil pressure senders. (see past posts). Is something to replace immediately since most do not return to zero and will not turn on the warning light/off the fuel pump if you lose pressure.

Orinoco;

Read carefully and follow precisely and report your results.

Ok?

Got it?

Turn your ignition to the on position.

DO NOT START!!!!!!

On the CRT enter to the gauges display.

Read and report your oil pressure. (NOTE: your engine must not be running!!!)

I use 10W-30 Valvoline or Castrol in my modern cars. Keep several cases on hand. Change about every 3,000 miles. Lots of past in-depth discussions of oil and filters.

At 6psi indicated, the oil warning light may or may not be coming on.

Are two types of oil pressure senders, the long metal one is famous for reading erratically, high, and not returning to zero. Is on top of the oil filter housing.
