What Matt said. Also possibly the inter-lock cable that connects from the shift assembly under console up to the steering col. There's a solenoid at the shifter that acts up sometimes.

Actually this is the same thermostat that was in the motor before the pump change, and I did drill 2 holes in before install about 4 years ago. And yes car was on ramps that I have been using for the last 20 years, (4) four stacks of 2 x 8's.

I've been wanting to change the thermostat to a 180* just because of the fan cut on/off changes I made several years ago. 215*\199* . I'll just go ahead and change the thermostat next week and start from scratch on the bleed.

Thanks
Joel

Just looked at that Lisle 24680 funnel, nice tool!

I have burped this thing at least 20 times in the last few weeks. I even ran a lever type rad cap for several days and drove the car around some, every time I stopped I would release the lever trying to get any air out.
Never had any problems with this car burping before this. I've had the coolant system opened many times over the years, and NEVER had this problem.

Now, I can't say 100% there is no air trapped somewhere in the system. I did change all the heater hoses when I installed the water pump, so this did introduce even more air into the system. Seems like a lot of people run these high flow pumps with no problems. Some people have reported problems similar to mine.

Just reading up on these "high-flow/balanced sleeve" thermostats seems logical that they could possibly help this issue, but they are all China made crap. At least the Stants claim they'er USA made.

Thanks for the replies

Any experience, opinions, etc. with this product? I've never used one of this type, always the Stant Superstat.

This will be for my 89 with a Edelbrock #8815 water pump.
I installed this pump several weeks ago due to my original leaking out the weep hole. Temps were good with old pump, usually 194-200 at light cruise at 45-60 mph and in town also. Have a 195 thermostat now, with coolant fans set to run at 215*, off at 199*.

After the Edelbrock install, temps are about 10*-20* warmer.
Temps also spike quickly and go back down while just driving along normal. Did not do this before.

Thanks
Joel

Just to update this: I finally decided to replace the water pump on my 89. Installed the Edelbrock #8815 thru Advance. Got a good deal with a $48 on-line coupon.
I did use the Gates clamps. Used the #32320 on top hose and at the lower hose to radiator connection. Used the #32324,which is a little larger, on lower hose to W/Pump connection. I'm happy so far with the clamps, they seem to tighten down just fine.

Thanks guys. I did look at those constant tension clamps, but I'm thinking they're just a little bulky for that tight area where the bottom hose connects to the pump.

I've used the old worm drives for 50 years on cars, very little problems considering the cost and design.

I got to change the water pump soon, that's really the only reason I would like to "upgrade" the clamps. I usually use the Ideal brand clamps, but they're getting to be poor quality in my opinion.

It's been many years since I had my hands on a TH400, but IIRC the 400 had a electric downshift. The 350 was linkage from the carb.

Glad it was a easy fix! I just assumed that kit was a plug-n-play.

The 1989 model year has a slight quirk in the "tune" that requires a longer crank time. Some info here:

If you're sure pump is running, I'd say pull the pump back out. Possibly the pulsator slipped off or even the pump is loose from feed line.

Yea, I understand about sticking with a tried and true product. That gas cap took some serious effort to look that good, just a regular polish would have been a waste of time. I use the Nu-Finish on "delicate" surfaces first before the more aggressive cleaners.

This would be a perfect example of the old saying "the more you screw with the worse it looks".
Have you tried Nu-Finish Polish to clean the bezels? It's a gentle polish that works good.

If you're trying to check the pump, ground the G terminal on the ALDC and then turn the ignition to on. Just don't leave it grounded for more than a few seconds.

If you're checking the relay just swap out one from the MAF power or the burn-off behind the battery. they're the same on a 89 model.

I already emailed the seller so we will see what the resolution is. And all to try to screw an unknowing/unsuspecting customer out of $2. Unreal.

Hope Tommy and Sue are having fun.

These are a real pain to find! For years I used the Trico Exact Fit, but they have changed the design on them and they hang up also.
Last set I put on my 89 came from the dealer #12363800 for approx 20 bucks. Worked good. But these are discontinued now!!
Not sure if the part number will cross over, haven't tried yet.

Try #12533416 GM parts.

Joel


I see the Delco # 8-2202 / 12533416 should fit.

You can jack the car up by placing jack under the K- brace. This this the wide metal cross-car assembly that is directly in front of the oil pan. Just be careful not to let jack catch the oil pan when you start jacking.
Next, check fluid level in pump and do not over fill.
Start car and very slowly turn steering wheel left to right,then back without hitting the bump stops. Turning wheel too far will just agitate the fluid making it harder to remove air. Need to do this approx 20 times or more depending on amount of air trapped.
It is a slow process, so don't rush it.

Part #16183247 for 1994 and 1995 only, H body which is the olds delta line, Buick LeSabre/Park Avenue line and Pontiac Bonnevile. Yard gets $40 each with a 45 day return. There's two more cars there so I'll go back and pull those out next for a spare.

Of course all this has just jacked up the wife telling me we need a "newer" car. Mid 90's are still late model for me.

I found a 1994 LeSabre at the local yard with damage to the r/s rear, this told me the car was running prior. Pulled the PCM and it was a reman unit,so that was another plus. Installed it and the car started instantly, runs perfect as usual.
Now I've got to decide on buying another reman unit for approx $230 or go back and hunt for another unit in the yard for a spare. Since this is the car I drive to Chicago to visit my daughter, I WILL have a spare just in case.

Just wanted to up-date.

Looks like the subscription is for one year as the shortest time allowed. Less than $30.00 for the sub for one car is great but bearable.

I haven't even looked on the E-bay for any manuals, I honestly never even think about looking there.

I'm going to look around for a used ECM for the car today, depending on price, just as a "let's try it gamble"

Anyone use it? I've got a no-start problem on my 1994 Le Sabre. ( Yea, I know-why not just junks it?) It's still a nice car with 87k one owner.

Injectors won't fire, no pulse, I'm at a dead end.

Thinking about a short subscribe to Alldata for this problem.

Thanks
Joel

Sorry about the car, glad you're OK!
When you start the inspection, use the best flash light you've got. Good luck

Joel
