L20B upper radiator hose insie diametre.

[Bentaxlebob]

Looking for the inside diametre size for the upper hose ( rad) L20-B engine. Anyone happens to have a hose handy? Looking to install a mechanical water temp gauge. Want to keep the OEM temp gauge connected and add the water temp gauge as complementary. That way I can see when the temp is getting dangerous and visualize what it really is ( stock gauge will only tell you your engine is 5 min away from blowing up....abandon ship !)

 

For that matter I need to install a sender adaptor that goes in the upper hose. I will post the part number and brand once I get the right adaptor for those interested.

Could not edit tittle. Meant to say inside diametre.

Measure the size of the thermostat housing and viola, you get a pretty much perfect measurement.

Pretty sure they're 1.38" 35mm

I'm thinking of doing the same thing

Check Glowshiftdirect.com

They're like 15$ and look great.

^{Hi. Got the part and ready to install the gauge sensor. But before doing so,I have seen that my Thermostat Hpusing has 2 bolts on the housing. There is a 3rd aditional lower opening where the stock temp gauge sensor hooks up to.}

 

^{I can always use the part I bought for another car, Anyone tried to hook the temp sensor to any of these 2 bolts/openings on the thermostat housing? I have been busy but plan on taking those bolts off to see if the sensor would fit. I am concerned about the thermostat. I think at least one of those openings is for the smog device temperature selenoid sensor for the air pump system.....air injection intanifold.....all that is gone.}

 

^{Will try post a pic of what I am talking about. If anyone has a photo ofthe Thermostat Housing,please post it.}

i hooked mine up to the side where there was 2 vacuum ports originally

[Ranman72]

I have 2 ports on my thermostat housing on L series motor

I used one for the stock gauge and the other with an adapter for the after market gauge

the threads near the front with the pink Teflon that you can barely see is the stock temp sensor the one on the right is the secondary spot

some of these have up to 4 ports

Thanks.

 

That is what I was looking into. I was not sure if the thermostat would be in the way. My housing has 2 ports besides the stock port ( on other side, just like yours.)

 

Good to know. I will connect my gauge into one of the ports available in my housing,.
