Tricks for changing these sensors?? ECT and oil press send..

Thanks again for your continued support and concern. I dread taking that
damn serp off (is that the OEM Helms manual standard for service??) because
I have a stubborn tensioner for sure... Ah well... We'll so what we need
to in order to get to the bottom of this one...
Thanks!
Andrew.

Andrew-with all the other stuff you've done the serpentine belt
should'nt be too tough for you. May be 5/8th's on the adjuster(not
entirely sure-have my breaker bar already set up in my tool box-use it
nearly daily) but...use a breaker bar with the proper socker or if you
don't have use your 3/8's or 1/2" drive ratchet with a small(one foot
or so)section of pipe or copper pipe, etc. to assist you. If it gives
you too much trouble maybe you have a bad tensioner. good luck-once
off, you should be able to use the proper extension to get that coolant
sensor out. Good luck jery.TakeThisOut@peru-motors.com

Andrew I changed the oil press. sender on my 95 W-series S-10. I don't
remember if I removed the distributor or not but I did remove the upper
manifold to give more room. If the distributor does have to come out it's
not too bad a job. Just mark positions. Mine was pinned in one position so
timing can't be adjusted by moving the distributor and it will only go in
one-way and be aligned correctly. Also it helps to have a curved dist.
wrench to get the hold-down bolt loosened. You may be lucky and be able to
reuse the upper manifold gasket but suggest having one located in case you
need it. A few years ago the p/n was Felpro MS95818. HTH
