Spring Projects
I'm planning my spring projects for my 94 LT1. I'm planning to pull the radiator and upgrade to a new Dewitt. Also flush the system and pull the knock sensors. While I'm in there I'll replace the water pump and thermostat and the hoses. The opti and serp belt werers replace about a year ago before I bought the car. Anything else I should do "while I'm in there"?
Not currently having any issues, this is all preventative maint. on a 23 yo car. Not a track driver, just casual and the occasional spirited drive.

I didn't see it in your list. How old is the pressure cap on the surge tank. When i changed my heater core I found my cap gasket was cracked. Didn't notice it till I was putting it on. So had to run get one. And everything local was 16lbs vs the factory 15 lbs.
your changing out almost the whole cooling system. i'd pull the passenger lower panel and look for evidence of coolant. Mine didn't get to the carpet but had coolant on the insulation on the panel.
It's a pain to change the core, but would suck to change all that and then find it leaking.

Hi guys - first post. My first project is trying to locate all the FX3 parts to reassemble my suspension - last owner put crap shocks on and threw out FX3 shocks and actuators. Gona cost a bundle if I can locate all these parts used, but I would really like to get it fixed back to factory.
It's a 1990 coupe - will 1989 parts work for me? Thanks!

After I pulled mine nothing came out. had to poke the hole with a small crew driver to brake a thin crust out then it flowed. And there is more coolant than you think in the block

you might consider adding a bottle of "wetter water" or "wetter water" to the new coolant. Its good stuff . I think I bought mine at Auto Zone.

Good idea. Lots of opinions on that stuff. I first used it on my British TVR. A really fun car, but always ran very hot. The water wetter did a great job to help cool the car. The stuff is a surfactant and lowers the surface tension of the water increasing the heat transfer capability.
