I have acquired a 1993 4 Runner and found two sensor/components broken off in the back of the engine. I identify them as a coolant sensor and a coolant switch. Parts store produces sensor and switch with different caliber threads. I suspect that this is not the original motor and do not know how to identify the year/model/generation of motor I need to order parts for. Any help would be greatly appreciated.
I have removed all of the air intake and many, many hoses and lines to access the broken parts which are above the trans bell-housing at the rear of the intake manifold. Because I am a "NUBE" and apparently "computer illiterate" , I failed to attach pic's to this post. Happy to e-mail pic's of my mystery motor if anyone who can help. Just ask at troylund444@hotmail.com troylund444@hotmail.com. (One of these).
The motor is marked with V6 3.0 EFI (on the intake manifold), 3VZ-E (on what I assume is the timing belt cover), and 65 100 3023 (on the final air intake that enters the aluminum intake manifold).
I have a 2 ton yard ornament until I figure this out. Thanks in advance...

 

upload pics to photobucket, then use the [img] tags to post them here

 

Here are some pic's of my pain. Can anyone tell me where to find numbers on the block or anywhere else to I.D. this 4 Runner motor?

 

thats a 3vze v6. the two on the back under the manifold are coolant temp and a bvsv vacuum valve that works closed until at operating temp than opes, this can be deleted and bypassed

 

Music to my ears... These have obviously been non-functional for some time and I will let them continue to do nothing. Thanks for the help.
