As soon as we pulled the Parts Cannon Pontiac out of the garage for a victory Test Drive, the engine started stumbling, and the P0107-MAP Signal LOW code popped on AGAIN!! WHY?
After resolving that issue, the cars runs great, but is it OVERHEATING?
Owner wants us to install a “toggle switch for the fans”…but WHY?

 1 YEAR of Pontiac PARTS CANNON?! (P0107 MAP Signal LOW…Again?? Overheating?)')){kind=link}
That add-on aftermarket gauge prob included a sensor that had a different range than the original sensor, hence the wrong reading on the original gauge. Unloading the 5V line was def the quick way to find the excessive load. Great fix Ivan!
Where is your Trump sign haven't seen it lately
If I remember correctly & someone please correct me if I'm wrong but the numbered temp gauges were phased out because people were freaking out over higher than normal temp readings. The higher temps were for a more efficient burn as fuel injection became more modernized vs TBI in the 90s. People were so used to seeing temps under 200 & newer cars were running 210-220 range. Thats why most modern cars now just have a sweeping gauge with no numbers.
or is the same stop leak coating the temp sensor giving bad readings? got myself burned by sensor lying I was overheating once.
Is it possible that the cluster gets a temp signal from a place other than the PCM? That used to be the case in the 90s and this is kind of a 90s car.
Not fixing the check engine light is a mistake, even in a non-emissions state, if he really wants to keep that car on the road longer. I know the EGR valve is probably a bit pricey but I'd replace that, too….
The parts collection in part 1 was just littered with wrong guessing, it’s not enough to get a cheap scanner, to properly diagnose a car you need to have a high quality scanner (expensive) several years of training either by YouTube or with an experienced mechanic and knowledge of wiring harness and electrical repairs.
I’m just in awe of your consistent skills and your ability to doggedly pursue a problem.
My mother, and i owned both an 85 and 86 Buick Centuries with the 2.5L Iron Duke 4 cylinder engines. Those engines were gutless even though they were very reliable fuel efficient for the time. The most common problems with those engines was both engine block cooling fan sensors or cooling fan relays. Years later while reading a page about the Iron Duke engines it was advised for owners of the cars with those engines was to install a toggle switch for the cooling fans which my brother recommended years ago lol.
Ivan, these GM cars with the 3.1 including the Buicks command fans at 226f, it's normal .
Another DIYer that caused more problems than they solved. It usually costs them 3 times as much when I get it than if they would have just brought it to me in the beginning.
Ivan you are actually a little spoiled compared to other Techs across the country… I live in a small Colorado mountain town and don't have the luxury of putting factory parts in everything… we have to deal with A/M on many things but if I stick to Standard, Wells, Echlin, Blue Streak etc I usually have pretty good results… run into more problems with A/M steering/suspension and driveline parts quality/longevity. Most of my customers can't wait a week to order in factory parts and alot can't afford them for across the board repairs. Isn't a perfect world for all mechanics especially outside the cities with every make and model dealership at your disposal. Luckily some of the parts stores do have access to certain factory parts though.
Generally the 3.6 V6 in Pontiac's are fairly bullet proof ,They were usIng them in T GM-H Commodore in Australia from 89 to 95-6 we love them even when they went to EcoTec they were still a good engine.

I know it is the customers choice but i would not run a vehicle without a good thermostat. The coolant doesn't stay in the radiator long enough to transfer heat. It probably will when idling but not going down the road.
Another awesome video Ivan thanks for sharing.
Great diag Ivan… Bonus of no parts needed..just your expertise…!! Kudos
Umm, he may still need a thermostat during winter driving. Without it, the engine will run cold and you won't get much heat, if any when driving on the highway. But if the customer is fine with that, then what else is there to say?
Great diag Ivan. What warranty did you give the customer on the Chinese herbal tea can.
Are you going to replace the egr valve
Or not needed?
