We hit the track with Flyin' Miata's latest power adder.
A few questions (car is BMW e36 3 series):
About the most complicated work I've done myself on a car has been brake work: changing rotors, pads and replacing brake fluid. Does swapping in a new radiator, hoses, thermostat housing and water pump sound like it'll likely stump me?
Does it sound like I'm missing anything necessary in the coolant system? I want to effectively replace the whole shebang.
Any tips for flushing the old crud out of the block/heater core?
Opinions on the BimmerWorld kit?
PS - I do know about the Pelican Parts walkthrough, btw.
There's also a bypass hose I would replace and the reservoir and coolant level sensor. Its all tied together in one mess and you want to change it all at once because its a pain.
Just did it all on the E46, definitely include the sensors, my coolant level sensor broke during the dismantle and the fan sensor O ring was bad
One thing I'd add is the belts (A/C and water pump). And I regret not replacing the overflow reservoir when I did everything else...
FWIW: just replacing the water pump on the e46 isn't a good idea - the overflow reservoir split the next workday when I did it that way.
I agree it's best to replace everything at once (including the heater core hoses - they don't look to be a fun replacement at the side of the road). Best thing is they are inexpensive when ordered online.
If you're getting aggro with the car it may be worth considering a Stewart water pump.
When I was pushing my '36 M3 over the cliff toward being a track car I replaced the whole mess w/:
Zionsville AL race radiator w/ AL o'flow tank
AL shroud + 16 SPAL 2 speed fan + 2 relay kits
AL t'stat housing
Fresh BMW coolant-distilled water-Redline Water Wetter
