What am I looking at $ wise for a do-it-yourself, spring project.

He said that he would be doing it himself.

Ok fellas, Went to NAPA today and ordered the kit, should be in tuesday. However I drove the cat today about 20 miles round trip some highway and some in town, didn't get above 210. sidenote... When I park the car and let idle with temp at 205-208 the fans didn't come on. 38 degrees outside temp. turned the heat on and no fan, turned the a/c on 60 degrees and still no fan. could this be the problem, and what should I do to get the fan on.

Fans should come on at about 224 degrees or anytime the A/C compressor is engaged. Try defrost. That uses A/C at any temperature.

Thanks Ranger. You and everyone else here are very, very helpful. I'll keep the forum updated....

Oh that reminds me, When the surge tank boiled over coming up my 1/4 mile drive as stated above the temp reached about 235 and the DIC indicated (A/C OFF). Could this be any clue?

[Ranger]

That just indicates that it overheated.

I'm curious as to why you changed the t-stat if things went good on your 700 mile trip. Maybe had air trapped after stat install?

Concours,
when I changed the pump I re-installed the original t-stat and rubber gasket. When I got back within a week noticed small leak from around the rubber gasket where it bolts to the housing. Replaced the bad gasket with a new one and t-stat. Should have done it the first time.

Fans aren't kicking on in defrost mode nor a/c, but a/c wont kick in due to outside temp around 30.

I will drive it around today and keep an eye out, Combustion gas test coming Tuesday. got a feeling (wishful) that it's not a HG....

Update:

Did the block test this morning and the fluid turned yellow.... HG is the problem. Thinking about a DIY job, but taking the engine out the bottom is scary. Going to call a couple home shop mechanics and see what they charge labor wise. After weighing all options it's not out of the relm of possibility to make the 7 1/2 hr trip to Onterio and see 97Eldorado.


Two things for sure: I do know I will keep the car and I will be using the Studs, anything other than that I will keep all posted.... Thanks.
