I had a chance to get underneath my 2008 ISF and noticed the pink dried coolant. I am unsure where the coolant can be coming from knowing that the valley plate and water pump are notorious for leaking coolant. Any other places I should look to be able to figure out where the leak is coming from? Also I posted a pic above of the LCA bushings that came with my car when I bought it used. They dont look oem but again, can anyone let me know if they are or what brand they are! Thanks and all information is appreciated!

 

Looks too low flowing to be a valley plate issue... It could be your water pump. if you take a look at the front of the engine and have a look at the water pump and see if there are any coolant drips or dried coolant coming from the water pump. I doubt it is the valley plate, but who knows.

 

will check tomorrow, Thanks!

 

It's the valley plate pooling up and leaking back onto your transmission.

 

The LCA bushings should be Figs.

Should i be concerned at this point and go ahead and address this issue or should i monitor the coolant levels and add accordingly? I really do not want to go through the hassle at this time to do the job and really dont wanna spend a lot of money to get it done somewhere else. Will this affect performance in any way to let it leak and how much do they typically leak/how often should i add coolant based on my 1000 mile/month driving? Thanks for the info!

 

Valley plate leak. Figs (SuperPro) polyurethane bushings.

Can you ignore it? Sure. Better check your fluid daily and have some on hand to top it off and if anything changes be ready to have it fixed ASAP.

 

Well, if it's your valley plate, you'll have a massive mess in the valley of the engine. You'll probably lose a lot of coolant, but fixing it is expensive and requires some work to do it (if you do it by yourself). You could ignore it, you'll just have to buy loads more coolant... and make sure that nothing else bad happens if you let it go, it could turn into a more serious issue. There really isn't a typical leak... yours look sort of normal, but they all leak different amounts. Also, if anyone knows, does the newer version of the 2UR-GSE (aka the engines in the RC F and GS F) have the same valley plate issues as the older version does?

 

My car has similar faint old stains on the transmission from a valley plate leak many miles ago

 

That's what I was thinking it could be an old stain do you know the history of the car.

 

I just did my valley plate leak and it leaked more along the top side of the transmission bell house (looks "veiny"). I recommend getting some hot water in a spray bottle and spraying it down and checking to see if it comes back.

Are your coolant levels fluctuating?
