thermostat replacement

[tomsj30]

on my 94 j30 i would like someone to let me know where the thermostat is located ,and if it's a problem or just pay to get it done?

You think you can handle it? about an hour if you know what you are doing.

The shop book shows 2.5 hours labor. I just paid a guy like $60 to do it which was cheap.

nismochi's pic shows area well -all the cam +crank pulley removal isnot necessary though .best to get a checklist noting exactly what was removed in order + anything to remark as special attention .the two short hoses better be replaced - water pump also would besmart to replace (I beleive it needs to be loosened or removed here) .One potential headache is one of the stubby bolts(w/rubber inserts) which holds left timing cover half interferes slightly with outlet of waterpump you gotta get creative , angle parts , shave length off a little,etc. but it can be done - or if you don't install that bolt it's not the endof the world either ! don't overtork anything going into aluminum/magnesium and youll be ok permatex water outlet silicone sealer is good specially made -non contaminating or corrosive stuff forthis job (w/pump and/or thermo) good luck .......
