cooling problem

IIRC, the TSB addressed the A/C condenser.

I linked to the infamous "Colorado Crunch Cobra" website from years ago in the following thread - the owner of the site had scanned in the TSB papers and corresponding part numbers/procedures for the
'96 TSB. Not sure if it is still online, but worth a shot if you are looking for background info:

Also, there are a plethora of mixed reviews on aftermarket radiators - lots of recent trouble with the Mishimoto (jury is still out on their new revised bracket, etc). Just do your research first if you decide on an aftermarket radiator - some people would say a replacement radiator from the local parts store or from Ford is your best bet.

Thermostat is located at the lower radiator hose near the driver side front of the car (low to the ground) - it will be in that housing IIRC.

Additionally, if you are not already aware the 32valve cobra engines have to be refilled a specific way, when adding coolant to the cooling system (you pour in at the coolant crossover tube location via removing that little 1/4" black plug direclty in front of the radiator) after any cooling system work.

Run a search for some of the previous terms if you need more info - there's a few past threads with lots of good info/detailed instructions.

G'luck.

just change your rad to a 03/04 cobra and save some cash > there fully alum and can be picked up on e-bay for around $150.00 some times cheaper.
