Belt tensioner arms over time and mileage bind up then jump instead of taking up and releasing belt tension smoothly. This will increase belt tension increasing strain on the belt as well all the accesory items driven on their bearings vs maintaining a constant tension during hot and cold thermal expansion cycles of the engine, components and belt.
That PS stunt with coolant in the system, how many times has the system been flushed by draining and refilling with PS fluid to remove all traces of coolant from the system? Coolant is the enemy of rod bearings as example but now it's in your complete PS system, ouch it may (will) bite you in the butt later in parts replacements and labor.
Had me thinking your starting in a cold climate, if a low ratio of coolant to water mix were added the water mix in the PS unit turns to ice, boom frozen pump and broken belts.
You should of had the LR towed to a dealership and let them do everything required to make everything right then presented the bill to the shop that screwed up which sounds like a court case a big cash settelement, parts and labor all in your favor.
Dealing with a scumbag extended warranty vs out of pocket replacement engine in my case I also had the LR dealership also fighting for me. Service writer and mechanic also personal friends for years.
Months of delays no vehicle parked inside the dealership while the clock kept ticking running out on the 7/100K warranty, Western General kept stalling and delaying the dealership from investigating deeper into the engine preventing them from coming up with more internal damage to be added to the warranty coverage bill. Their replies not being answered to several questions sent to them.
It took a letter with an attorney letterhead across the top to convince Western General their 7/100K mile extended coverage after they were ordering the dealership to do a patch job on the wounded engine to function an additional five plus weeks longer being just over the end of their 7/100 coverage before the engine would of failed again.
Nope, factory new LR shortblock installed along with replacing the timing cover replacing the faulty oil pump with a new timing cover / pump assembly that already had damaged the engine. New shortblock along with new timing cover / pump assembly.
Would of hated going to court but hated more spending over $8,700 out of my pocket my money when all said and done.
All the best getting back up and running again. Check all idler pulley bearings or replace them as they have a hard life spinning two to three times faster the the engine. I'd also carry a spare belt along with wrench to unload the tensioner arm. Broken belt on the side of the road just a belt failure not any accessory or idler bearing failure you'll be glad you had that spare belt and wrench. I don't leave home without them along with tools, digital meter, spare distributor, alternator, tape, gallon of coolant and quarts of oil. All this as important as having the spare tyre. Failed starters not an issue I can bump start this five speed.......~~=o&o>.......
