Replying to: the_big_al (Oct 03, 2009 2:34 pm) Low coolant will effect heater operation. Seeing you have a V6, I would suspect the infamous intake manifold coolant leak, most times they will leak external. That's good news for you, get it repaired ASAP.

Replying to: gonogo (Oct 04, 2009 5:53 am) although I am not looking for a step by step process (I'm pretty good at reading a chilton ), but what is the basic process to do this?? Replies to this message: gonogo (Oct 07, 2009 6:13 am)

#34 of 36 S-10 cooling....1st time poster by jetjunky Nov 08, 2009 (9:55 am)
I have a 2002 S-10, 4.3, A/T. I just change the thermostat to a 195 deg. The operating temp now stays at 210 deg.( mid range on the gage ). My question is will this be detrimental to the life of the engine, will I see any difference in mpg, any adverse effects in warmer outside temps? I live in Phx. Ariz. so the temps can get quite hot in the summer months. What is the recommended operating water temp? Thanks for any help. Replies to this message: the_big_al (Nov 11, 2009 11:02 pm)

Replying to: jetjunky (Nov 08, 2009 9:55 am) As far as I can remember, my S-10, an '01 4.3 A/T has always read right at the 210 (midway) point once warmed up. In the summer it has been dead on mid-point and in winter it reads just a hair below. My truck also spent several summers in Phoenix and I had no problems. I have the standard 180 degree (I think it's 180) T-stat. I have changed it once and I stuck with an OEM one.   You won't see any damage if the temps stay at 210. What you do need to worry about is that in the summer, you might see the temp range in the higher side rather than the low side because of the 195 degree t-stat. That is something that I would be careful of. Instead of operating between 100 and 210, you are now operating between 210 and 260, which can get dangerous on hot days. Especially in rush hour traffic traveling at only 10 MPH.    In my opinion, I would switch back to the standard factory t-stat. Is there a reason you went to the 195 degree one? People make all sorts of claims pertaining to running one, but I haven't tested it to be sure and so I don't know. They all sound like hocus pocus to me.

Replying to: peter931 (Mar 31, 2009 12:56 pm) You could be 180 degrees off? At # 1 cylinder both exhaust and intake should be loose if you want TDC ( top dead center)? This means that. both intake and exhaust valves should be loose upon inspection or both are closed. This is a common mistake and don't feel bad about it! When you turn the crank, the rotor should be pointing towards #1 on the cap or distributor? Wires for #1 should be located at front not back of engine. Hopefully, this will want you!
