That was indeed a whole day. Caravan now back in the parking spot blocking it in again.Fred wrote:That's basically a whole day
- DONE! Drive it out into the open
- DONE! Refill it with straight water
- DONE! Bring it up to temperature, perhaps with a drive
- DONE! Dump the water, flushing as much as I can through with the hose
- DONE! Fill with concentrated oxalic acid - no fear of water pump issues, it's coming out anyway. The rest could do with a derust :-p
- DONE! Take it for a drive to get full cooling system coverage at a nice high temperature
- DONE! Come home and dump the acid out
- SKIPPED Flush with fresh water a few times until satisfied
- DONE! Fill with strongish solution of sodium carbonate (not bicarbonate like last time's minor fail/explosion)
- DONE! Take it for another drive to ensure that circulates through the entire system too
- DONE! Bring it home and dump out the carbonate solution
- DONE! Flush with water until satisfied
- DONE! Oil change, fill it with cheap 15w40 and maybe a new filter if it's lucky :-p
- DONE! Blow cooling system parts/engine dry with compressed air
- DONE! Back into the garage she goes
- DONE! Remove hoses from water pump and radiator
- DONE! Remove radiator from car and flush with water
- DONE! Pull the water pump off the engine
- DONE! Pull the alternator off the engine
- DONE! Pull the trigger wheel off the engine (blocks access to large bolt)
- DONE! Pull the pulley off the engine (blocks access to small loose bolt)
- DONE! Degrease the front cover and clean under the water pump etc
- DONE! Pull the loose bolt out and clean the hole
- DONE! Put away all tools, neatly arrange parts so they're not lost
- DONE! Hose down driveway extensively half a dozen times...
- Measure the hole depth, find a suitable replacement, torque up the new bolt with locktite
- Get the alternator fixed up and in good shape - as quickly as possible, reinstall as is if no luck
- Reverse of the above, but with new water pump and refill with nice green coolant for the first time in years, LOL.
So left to do are:
- Sort out the bracket fastener situation
- Tweak the bracket to give more clearance for drain bung and water pump bolt
- Fix one radiator mount bracket
- Derust and paint a few items
- Pull the radiator support out of the car, clean up, paint, reinstall
- Scrub rusty water stains from fan shroud
- Scuff up the pump mounting face until bright steel
- Clean various fasteners that are greasy and/or rusty
- Install the new water pump with a small amount of well placed silicone
- Get the alternator fixed ASAP
- Reinstall pulley, trigger wheel, bracket, sensor, bolts
- Reinstall alternator and belt, tension belt correctly
- Refill with water for the first time, bring up to temperature, check for pressure and leaks
- Drain water, refill with glycol coolant at 35% and water 65%
On the weirder side, it was slower post oil change! Why?
1) Higher oil level
2) Old oil was broken down and thin
IE, higher net friction post change.
