Stant10231 Radiator Cap - 16 PSI Vented

This Stant 10231 Radiator cap 16 PSI with a Vented in case of over presser. is very well made It fit my stock radiator for a 1994 Chevy S10 4.3L I am using a stock fan with a 160 degree water temp.and I have no problem over heating it stays 160 even on the hottest of day in traffic or the coldest of days around outside air temp as low as -8 degrees.Im sure you will love this radiator cap I sure do.if it ever needs replaced I will try to buy the same name brand and PSI by Stant.Also in mind I am using a stock air cleaner with a paper filter with stove pipe.from the exsust heat.that will make warming up the best so the computer will know it is warm and go out of open loop mode.when open loop mode is working than the other sencers start working and better fuel mpg starts.

I would have gone for the lever type cap, but this was great so far. my old one was cracked rubber seals, the budget price on is great. car should jot boil over anymore

It's a radiator cap. Not much more to be said here. I seem to be having issues with escaping coolant. No leak, but when the motor is warm I can get a coolant aroma around the engine compartment. I figured the stock cap was 18 years old, let's get a new one. The old one may be opening under higher than the suggested pressure. That's what led me down this path. I can't say yet if this is the end all-be all.

Good cap, works well,

I bought this cap because I've been having problems with the cooling system in my 98 Jeep Cherokee 4.0L. This item was exactly the right specs and very much like the OEM that I took off. I had bought another cap from NAPA in my area and that one was a complete failure. This product was snug and was shipped quickly. I highly recommend the Stant brand for most replacement parts. I will be ordering other products from them. Great company.

Fit perfectly and works perfectly on the Dewitt’s Radiator in our 1969 Mustang, with a 351W and a coolant reservoir set-up.

Almost a good idea to buy this even before your old cap dies. Mine was leaking so I ordered this and did the quick swap. Old one was probably the original and 20 years old.So much easier to take the new version on and off as the old one was in bad shape. Just crusty and old and was much more difficult to take off.

Great cap fixed my slow coolant leak
