Coolant leak from intake...

Coolant leak from intake...

Postby dacosta [OP] » October 20th 2009, 4:00am

I recently replaced the radiator, and water pump on my 2000. I check for leaks with a rad pressure tester. I got some leakage from the front corner of the intake. Very small and under about 15lbs of pressure. I dont want to ask how difficult it will be to remove the intake. It is not leaking into the engine - only out the front and down the block. There is a small water stain on the side of theblock - so I dont think it is very bad. However I am going on a trip soon and was wondering if I should run the van with the cap vented or shoudl I switch it to lower pressure cap - maybe 7lb or something like that? Please advise. Thanks Dan

dacosta,
Lowering your caps pressure will only lower your coolants boiling point.
Fix it right, carry plenty of water, enroll in a AAA towing program.
You pick.

I would also have to vote on the fix it right idea. Lowering your boiling point would not be a good idea, especially since you have a leak.

You could try a "snake oil" block type sealant that may help. But going on a long road trip, I'd fix it right.

X3 on the fix it right, if things are half clogged up to start with, the stop leak can gum it up worse.
