'87 GXL



I have three questions...what does the afm look like?? Is it possible that a car can run without an afm? I think that the previous owner might have removed it when he installed a k&n cone type filter on the car..(the cartoon pictures in the haynes manual don't really help any)



Second question, does anyone know where the blockheater is on the block??? I noticed that the plug is just hanging down...not really helpin me out in canada. It's freakin cold and I get worried about leaving my car in the parking lot for more than a couple of hours.



Where abouts could I get a new coolant overflow resevoir??? I think mine is cracked...there is a slow coolant leak...I can see the coolant pooling in the chassis just infront of the radiator. Is there anything else in front of the rad that could leak coolant?? Tried mazda trix (I think they stock the most oem parts on the net) but they don't have resevoirs for models past '85.

1) no, unless there is a standalone or aftermarket computer installed



2)unsure, wish I could help



3) multiple guys in the forsale section parting out cars that you can ask, they surely can help you out. you also have a heaterline on the bottom of the lower radiator hardline, the clamp may be loose, or your radiator drain **** may be leaking, or worst case your radiator itself.

there are no aftermarket computer parts on the car...do you know anyone with pics of or around an afm??



I'm pretty sure it's not the rad...looks fairly decent. I need to clean it off though and see if the white build up on the front is just salt from the streets. I really think that the leak is infront of the rad...coolant drips down onto the chassis parts that look like skid plates.



thanks for the help

I live in canada...I think it's almost required to have a block heater, and I have seen them plugged in. I do have the block heater wire, just don't know where the block heater is...I'm assuming that there is one, and was never reconnected whent he motor was rebuilt.

I am not sure where you would even be able to put a block heater in for a RX-7, more than likely it is a tank heater plumbed into the heater core lines, when the rebuild was done the tank itself possibly was not put back in teh engine compartment.
