Okay guys here is my problem, i redid all of my coolant system. I have found plugs for all the holes except, there is a hole just above my heater house on the driver side and right under the filter area. I cant find anything to fit in it. Can some one please tell me what size of thread it is???? thanks this is the last thing i have to do so if some one can help out it would be appreciated.

 

why are you plugging them? just run a piece of 5/8" hose from the other side of the engine and connect it to there if you arent using your heater

 

no i am using the heater hose im talking about the small hole above the heater hose, its very small and i cant find anythign to plug it

 

Are you trying to plug your oil or temp sender hole? Those are the only holes I know of above the heater tube. If that's the case, plug them with the senders.

 

its the water temp sensor hole.... The easyest thing to do is get that sensor and put it back in to plug the hole... BTW you should be useing that sensor so you know what the water temp is anyway...

Guys this is a completly modded car, i have mechanical gauges to tell me what everything reads, dumby lights are pointless, i will figure this out trail and error. thanks any way

 

trial and error

 

Get the stock sensor. Read the Size of the thread and then use something that size.

 

i dont have the stock sensor, the car did not have one when i got it, it had a brass plug in it and all the threads were smashed.

 

pull one out of your parts car.

 

well never mind guys i will figure this out on my own, seems im going to have to. i only have one car no parts car. i thought this would be simple to figure out but doesnt seem that way now

 

what happened to your original sending unit? i would suggest taking temps from there anyways since its how the car was made.

otherwise, dig through your shop and find a bolt that'll fit to plug it. i personally wouldnt do that though. if you are taking temps up near the rad hoses you have to take into account the thermostat and how those wont ever really be that reliable.

g'luck

 

I tried all of my taps, both metric and sae, none of them fit in the temp sender hole. Chanches are the brass plug was stripped because it was close, but not the right thread pitch. I know the oil sender is that funky 3/8" bspt, the temp sender may be something similiar. A stock sender, even cut down will be your best bet and fit.
