Have a coolant leak and nowhere out of the winter to fix it. I've got it reduced to a seep (< 1 oz a week) using epoxy and that should hold me till spring when it is warmer. So, I'm going to change the radiator but in looking at the radiator removal video it looks pretty involved so I have some questions and need some advice. (I know, asking for advice can be dangerous. :-) )
1. Do I have to vent the A/C system to change the radiator?
2. I'm going to change all the hoses.
3. What else should I change while the front end of the car is off? Thermo changed 2 years ago. Coolant Temp sensor? Crank angle sensor O-ring, or the crank angle sensor as well? The A/C comp was changed in 2012. The multi V belt tensioner? ANy ideas would be helpful as I'm not maintenance averse, but then I don't like taking things apart unless I have to. I've got plenty of time to get ready with all of this stuff.

 

Nope....just support the ac condensor, fold it out of the way.
"Service mode" can be done in about 30 minutes...looks dramatic...but not too bad, honest. Did it the first time, no diy.

 

There's a couple things you could do while the car is in service mode for the radiator: Coolant flush (obviously), fan relay kit if it hasn't been done yet, radiator foam (if it is deteriorated or missing), crank sensor leak, visually inspect the water pump for leaks, as well as any sign of oil leaking from the PTO gear on the supercharger.

I wouldn't waste the money on a new crank sensor o-ring, just clean the leak up with some mineral spirits and brake clean, then remove, clean, apply black RTV to the sensor o-ring and reinstall. The o-ring will just leak again, any time we're in the area of the crank sensor doing work we will take the time to clean and reseal it, it's a quick job and once done properly doesn't leak again.

If you're "part time" Michigan residency is through the winter months we would be glad to help you out!

Get a Mishimoto

 

Thanks, NKFRY. Water pump, thermo , A/C comp replaced 2014. Already flushed and replaced coolant with water free coolant. No blower. I Christmas and summer in Michigan. Do you have any recommendations for anyone who works on convertible top mechanisms on the west side of the state. If not, how about in your area.

 

Depending on mileage and age, I'd just replace the 3 main hoses and the hose on the bottom of the reservoir. The rest are a serious pain to reach. Concur about the AC lines. The DIY instructions will tell you to just carefully swing out the condenser, then support it on the bottom to keep it relatively level. If you intend to keep your car for a long time, +1 for the Mishimoto. Lifetime guarantee...no matter what.
