Default question on gauges and tranny cooler...

okay I don't know jack about gaues and what they are measuring...

Water Temp Gauge - What does it measure? I mean I know it measure water temp, but where?

Temp Range - if I get a Tranny and Water temp gauges, what range should I get them in? 100-250F? or 140-280F?

Tranny Cooler - Which is a good one? For those with BM Racing Super Cooler, what size do you have? Thanks!

Anything else I should know about? Thanks!

Water temp gauge is just like your temp gauge on your dash. It measures the coolant temperature.

I would get 100-250 for water temp gauge, but that' my personal preference. I can't say anything about the tranny temp gauge.

Are you really concerned about your tranny oil temperature? Do you have auto or stick? If stick, I wouldn't worry about it much. If auto, it may be a good idea if you drive hard. Do you have a turbo on your RS or something?

I would get oil temp gauge or oil pressure gauge. I have a oil pressure gauge on my car because I don't even trust the oil idiot light on the dash. If that lights comes on while you're driving, then your engine is already dead.

thanks a lot tmat3. Yeah I have an auto and I autox that's why I want to get a tranny cooler. Man, who came up with these names anyway? I would have known if the name was coolant temp gauge!

Okay, so this oil temp gauge is the engine oil? Can you explain a little more on the purpose of the oil pressure gauge?

again, i don't know jack about these thing, well heck, cars in general! but coolant is used to cool the engine oil down correct? If I get the oil temp, I don't really need the water temp correct?

what about this vacume gauge? what and where does it measure? what's the purpose of this gauge? thanks!

I would say that if you are going to AutoX with an auto then go with the Water Temp guage, Tranny Temp guage and Oil Pressure guage. This will be a good starter guage pack. Later if you start messing with S-AFC's or chips or whatever you might want to go with an Air/Fuel guage. Help you tune the car.

Oil pressure will more than likely have to be tapped into at the original oil pressure switch behind the alternator. I'm still waiting on PAM from ISR to ship the parts I need to do this. They are so GOD awful slow! 3 weeks and counting. And she said she'd ship it the next day. HA!

I'm not to sure where you can pull the water temp from. I would suppose on the heater hose going to the heater core but again I'm not to sure on that.

Tranny temp guage is another tough one. If you go with a good tranny cooler you could tap into those hoses. Just be sure to tap into the line that is coming from the transmission and not the one that has been cooled. I have found a fuel line "T" tap in the JEGS cataloge. Has 3/8" openings and 1/8" NPT female fitting for your sender. Haven't checked to see if the openings will be to big or small.

As for the tranny coolers, I've always heard that the plate type cool better than the thin fin type. I will be using a plate type on mine when I'm done with the stereo system.

Oil pressure gauge measures engine oil pressure. On our cars, you should be running around 75-85psi at 60mph, 25psi at idle. At least that's what it says on mine. If the oil pressure gauge reads really low, that means your engine is out of oil and engine will die permanently very soon.

Oil temperature gauge measures engine oil temperature. It may be a good idea to have if you drive hard in high temperature locations. Oil that's too hot can lead to engine failure. You should drive hard only when the engine oil is at normal operating temperature (I think it was around 70 Celsius, but not sure).

you have an auto and auto-x a lot. It is a good idea to have a transmission cooler, but not truly required. Either way, make sure to change your tranny oil every so often. 30k for normal driving, and 15k for frequent hard driving.

thanks a lot guys! now I have more question...

Can someone explain the differences between the plate type and the thin fin type cooler? Pics would be nice.

So for now, I am pretty much set with
- Oil Pressure Gauge
- Tranny Temp Gauge

But should I get a water temp gauge or oil temp gauge? I drive mostly in the bay area and I don't think I'll be moving anything time soon. Mostly in San Francisco, Santa Clara, and Santa Cruz area. I really appreciate all your helps! Thanks!

I have a B&M Supercooler. It is the 19000 GVW model (#70268). I like it because it seems much more durable than the Hayden one. THe B&M is a plate type cooler. It was about $42 at carparts.com. It fits perfectly. I haven't measured how effective it is yet.

Where are you getting the tranny temp gauge from?

Default Hey Blue!

I bought the B+M polished aluminum racing tranny cooler and the B+M tranny temp gauge. The cooler was $49 at a local speed shop and the guage with complete installation kit (t-fitting, wire, etc) was $43. I also got some anodized fittings.

The B+M looks like the way to go. Smaller, more efficient and clearly more solid than the Hayden. Check their website for a detailed schematic of how it looks and works.

I haven't installed mine yet but will be doing so over the next few days. I am now considering bending my own 3/8 " steel tubing instead of using hose to supply the oil to it. I pulled all of the shrouds this weekend and it looks like the only challenge will be getting the tubing or hose from behind the radiator out to the front grill on the underside....I will have to bend a metal heat deflector and perhaps cut or bend the plastic engine undercover. I also plant to mount the tranny cooler in front of the A/C cooler leaving about 1/2 to 1 " of space....the guy at the speed shop suggested using rubber to insulate it from the mouting bracket to minimize vibration which could froth a fluid (I'm going to check on this with some techies).

As for the gauge....you need to install it inline with metal tubing (the line coming from the tranny is 3/8" metal and ends 3" from the bottom left of radiator). I'm not sure where I will put the gauge but I will probably stick it somewhere temporarily...like steering column or center console....I plan on a 3 gauge setup using a defi pod or something later with multi function Westech gauges....

I'll try to take pics as I go and post them here.

Interestingly, the B+M can be used as at tranny fluid or an engine oil cooler.........and there is ample room for two in the front grill area...one on each side or stacked.

Willman, the hose routing was no problem. I mounted mine in front of the A/C condenser on the driver's side. The hoses went from the top of the cooler to an opening near the top driver's side corner of the radiator.

I was going to go with steel lines too, but I figured the stock lines are rubber anyway, so if you want absolute protection against the lines bursting (which I doubt they would) you would have to get rid of the stock lines too. I think tranny cooler hose (it's actually called this at Autozone...you have to ask for it) is good enough.

The installation kit (which you may not have gotten with the race version cooler) includes little foam pads that go between the cooler and whatever you are mounting it to. These look like they will reduce vibes. They place the cooler about 1/4" away from the A/C condenser, which I think is enough for me.
