I have to agree…anything under the dash is maddening to fix. You have to damn near be a contortionist

Bought a Chevy truck to beat around, 2011, 4 x 4. One headlight was frickrd up so ordered a new one from RockAuto. It was the whole lights, blinkers and all. Couldn’t believe all the shite I had to take apart to get the old one out and put the new one in.

If you look at it from the standpoint of what SHOULD be an easy job (but isn't), it is the heater core without a doubt. The most complicated job for such a basic component. Take it to a shop and ask what they will charge. You will see 3-5k in labor.

They specifically engineer components in cars to last the warranty period and then fail. It takes a lot of engineering to plan it all out so that it fails immediately after warranty, but they spend a lot of R&D making sure this is the case. It makes no sense from a business perspective to make components last - they want you buying a new car every 2-3 years.

Rebuilding an automatic transmission. It takes experience. The solenoids are easy though.

I rebuilt an automatic transmission all by myself. It did not last very long.

After watching this experienced mechanic bash away with a big wrench on his wheel housing for 15 minutes trying to disassemble it, I decided to take it to a mechanic.


A YouTube video pretty much tells me all I need to determine whether I fix it myself or take it to a mechanic. I have saved alot of time and frustration on a couple of potential self repair jobs. Also have saved a boat load of money on some relatively easy repairs that a dealership wanted an outrageous amount of money for parts and labor.
Replaced windows regulators in Cadillac dts on all 4 doors. I replaced these as they failed and not at once. Also replaced fuse block on same vehicle after fuel pump relay burned up. This was a known issue and the dealership wanted a small fortune to disgnose and repair. 75 bucks for a relay block and the problem was solved. These two repairs should give an idea of the wonderful quality of this vehicle. All this happened before 100k miles.

I had a car that the battery was in the worst place imagineable. It was in an area in front of the tire and the only access was to pull the driver's front tire off.

Whoever designed that crap ... needs to go behind the woodshed for a good old fashioned arse kicking.

Think it was on a Chrysler Sebring but not 100% sure.


There were several Chrysler models like that.

Imo heater cores


I used to work for a company that sold some parts/supplies to dealers. I had gotten friendly with the head mechanic at a Mercedes Benz dealer.

One day I walked into the service area and he had a 1980's era big sedan (maybe a 560?)all torn apart with stuff covering up three bays, all spread out. Engine on a stand, dash parts, pretty much everything but the frame.

I asked him what in the world he was fixing on this car. He told me "Heater core." As is usual with many German cars, they start with the frame and firewall and build out from there. And the heater core is one of the first things to be installed at the factory. He told me that the Mitchell labor guide for that repair was tons of total labor since you had to pull almost the entire front interior and the engine. Said it would be several thousand dollars for a dealership repair (and this was over 25 years ago).

That's insane.

That's inconvenient, but doesn't seem like a horrible repair job...

This! I can build a powershift in a scraper tractor and have it come out no problem- I TRIED once to do a stuipid simple C6 Ford, and I fried it in less than an hour.

Those guys that can build new 10 speed autos are a different breed.

Something about having all the clutch packs in line.

For all the heater core people- don’t mistake tedious and straightforward for actual hard AF to do it right.

Heater cores are a pain in the arse but I would have to say a timing belt or chain. I’ve changed out pretty much everything on an engine.
